In case you noticed, the efficiency calculation numbers were incorrectly stated, but the efficiency of the unit was correct. I explained more in PART 2 of this video. Thanks for watching!
Hi, has you uploaded the part 2 yet? Thanks!
Very helpful video. Thank you👍
You state there is a 220v version, do you know if it’s 2 phase or just 2 load on same phase?
@@fullyelectric 1 phase
What size battery to inverter cables are you using?
Absolutely terrific review! Always a thumbs up 👍
Much appreciated. Thank you! Looking forward to Monday's video.
Project farm getting ready to burn some inverters lol
dam if you project farm gives a kudos to a review, you know your doing something right!!!!!!!!!!1
Please make a video about this
I'm glad he mentioned he got it for free. I typically avoid - infomercials. He comes off trustworthy so I kept watching. I'm new to electronics. B4 this video I was pretty confused by all the different terms - amps, volts etc. This man is so thorough and easy to understand, I have a much better comprehension of how to hook up my solar panels to an end inverter to my batteries and be many steps closer to self-sufficiency/off the grid.
Hi Jules. I always mention if it was offered to me by a company. Normally I buy or request something be sent to me for review. I have many companies trying to give me products on a weekly basis, I turn down the majority(95%).If a person likes what they see, then I include a link to support my channel, if they don't like it, don't buy it. I don't create videos for the sole purpose of selling products like many other YT channels. I'd rather have more views than product sales. I have another 3000W that was shipped by another company, I'll be making a video soon. Be sure to look over my solar and battery testing video playlists below, also share. Thank you!

Your videos are excellent! I used to work in the field and am retired now, you keep me up to date on the new stuff. I also enjoyed your inrush current videos.Thanks for posting!
Awesome, thank you!
Wow...the end was a real bummer. 😦 I watched the whole video and thought that this inverter would have been a very reliable unit, until it was shorted at the end. But, this was still a great video!
Wow amazing review. I shared the video just a couple of minutes in. I was originally trying to find what size fuse I should use for the inverter. After watching a lot of video's trying to see what others are using, this video taught me more than I expected. Great Job 👍
Thanks Bill!
Probably the most detailed and best review I have seen for any product, I think, EVER. I just purchased this unit and am very glad to see you took the time here. Very informative! TYVM!
Thank you! Glad you appreciated and enjoyed the video.
The 24v 3Kw version is now on sale at Amazon for $265.66, so I decided to search CZcams for reviews. I have to agree, this review is very good, as good as those by Will Prowse. I believe that over time you will get more viewers. I have been aching for weeks on which pure sine wave inverter to purchase, and based on your review I am now going to pull the trigger. I will test it as you have shown (except short circuit), and if it fails I'll just send it back. As one person remarked, the makers of cheap foreign inverters leave the QA control to us, which is part of why they're cheap. I will do my part and QA it thoroughly.
@thefeet Are you still happy with your unit, I was set to get this unit until the ending in this video! I recently had to return another brand (Ampeak) because in a technical jargon kind of way, they said that the pure sign wave is not %100 of times!
@@alharrison3255
I think the unit is 1500 watts steady power and 3000 watts peak,
I Bought one too after seeing this video.
Fantastic review & that ending was quite something & unexpected! Great job! 👍👍
Glad you enjoyed it! Be sure to share. Thanks Steve!
Hello Doug, Good review as always, it's what makes your channel of interest. Your definitely unbiased. Watching part 2 in a couple minutes. All the best, C
Thank you!
Excellent video. Thank You for testing this unit.
Glad you enjoyed it! Be sure to watch the next inverter review tomorrow at 9am EST. Thank you
Wow! This needs some good amount of effort for testing and patience 👍. Appreciate your systematic testing. Like others, I wasn't expecting that ending! I'm sure in the days to come, this video is sure to pick up some momentum. Do let us know if you were able to the comments from the manufacturer in your video description 🙂. Eagar to know the reason for failure! Thanks for the 👍
I already spoke with them, and they sent a video showing a brief short circuit that worked. I suspect it worked for them, because they didn't have a huge battery and thick cables connected to the inverter for their test. My setup, a typical setup, can supply much more current than theirs. Thanks for watching. Be sure to share the video link with others. Unless videos like this get at least tens of thousand of views, they end up a huge waste of my time. Thank you!

Yes absolutely that was a great video I watch the whole thing right through understood it you explained it very clearly even to someone who probably has no idea about electronics whatsoever would’ve understood what you did in the last test said at all so that’s a huge deal that would’ve been a waste of money for a lot of people thank you appreciate that very much

Was not expecting that ending. Overall good unit if used as intended. Good review 👍
Me either. Now I need to fix it. When I do, I'll add a 25A push button breaker to the output. :-)
@@electronicsNmore Definitely make a video of that! Seems like a great unit outside of this one shortcoming. Love your videos!

@@electronicsNmore all you had to do was disconnect it from the battery then reconnect it and it would have reset and worked
@@AlabamaConstitutionalCrusader Incorrect. The unit was damaged, The company admitted there was a problem and they also tried making a different version inverter board, which still fails. If you doubt me, try it.
Nice no nonsense video thanks!

great video! I love my Reliable inverters. I have 2- 3000w, 1000w and just got a 600w, all 24v and from amazon warehouse for way less than retail.
I like them too, just don't short the AC output. :-)
@@electronicsNmore yea. dang. I seen that. Im actually fixing one i bought for $17. one of the mosfets was blown. waiting for them to arrive. should fix it. Where you able to fix yours. It may have just been a diode?
@@RodneySolarCircuitswhere did you find the unit for $17? Sounds like a fun project

Thank you @electronicsNmore for your thorough reviews. I recently found your channel and I just wanted you to know what a great job you are doing. It is obvious you are a master at your craft but what is even more impressive is your ability to teach so well, thank you again.
Where you able to resolve the issue with this inverter, I saw your followup video but I wasn't clear if it was resolved. Overall, do you recommend this inverter, less of the shortening failure and its downfall?

The company never sent the parts.
I recently purchased this model for running our furnace if power goes off. In this part of Minnesota we have experienced -40f to -50f (rarely) real degrees not windchill. But anything under freezing would be bad for our house. OK. Great set of tests that I was curious about. Sad about bricking the unit with the ac short test. But as stated, it looks good for the price. Thank you!
It's not a bad unit, but I found one better. You can see it in my newer video below. Thanks for watching Ray!

I know David Poz had an issue with their 5000w model, and they took care of him promptly. He says the company has good customer service. This video is very useful.
As I am considering purchasing this model inverter, this was an excellent review. Shame about the ending... didn't expect it to destroy the inverter.
The ending wasn't pretty! LOL Be sure to watch my newer inverter testing video below, I show a better 3000W pure sine unit. Also check out my very wide range of videos, and share. Thank you!

Great video, very informative. I have been using this exact model inverter for over a year to power my off grid solar home. It has worked flawlessly, 24 hours a day, and I have had zero problems, averaging 10 kwh a day output. I was surprised to see it fail after a short circuit on the ac output though, i would think it would trigger the overload protection before it would fail internally.
i had the same issu, a short circuit destroyed the board. Dont buy this anymore!!
Did you put an FI Switch in Between?
Would be interesting if that would have saved it.
Thanks for the video. I see WZRELB has many good power inverters.

You're welcome!
The 8:00 minute mark told me the answer I've been searching for. Thanks!
Great review
thank you sir for proving that this is not a short protecting device on the AC outlet... what more on the DC side of the Battery...
I have this unit. Have had it for about a year or more now. Started with 100w solar and 200ah lead acid batteries. Now I have 200w solar, 40ah li battery (soon 80) with a wanderer charge unit with temp sensor. I haven’t had any issues with the inverter, however I don’t use it for heavy loads. Just mainly charge yard batteries with it and the occasional power outage I’ll run tv, lights etc. My main weak link is the batteries which I’m slowly adding. It’s overkill for my intentions, but has been a good unit so far.
Excellent comprehensive tests I must say. I own a 3500W 24V version myself. Haven't blown it up.....yet. I am amazed it still "tried" to run with the overload, but only @ 98 volts or so. That is a fail. Below 108 volts is beyond standard grid tolerance. I know if I run a 1500 watt microwave, the output is around 112vac. Yes, still in spec, but I still don't like that. After watching some others review similar models, we learned that those ATC fuses are pretty much a false security. Usually the MOSFETS blow to protect the 20¢ fuse! I want to add some kind of "fuse" at the output side, but it's got to be super quick acting if there is a full on direct short like you did. Say I put a 15 amp ATC fuse inline and try to start say my circular saw and it blows. OK, kind of expect that maybe due to inrush current. BUT, say I do what you did and create a full direct short....Will the fuse blow before the inverter blows? Hmm. I DON'T really want to test that theory right now!
Anything 110v or higher is fine. Thanks for watching!
Yep the lack of proper protection on those mosfets at the input is the problem. Kinda sad because this is a great unit other than that crucial error. Almost comical that they could put blade style fuses in to protect mosfets on an inverter? Gotta wonder if any of these engineers have experience in the industry or what.
Still at the price point its hard to say this isn't a good buy. In a situation where you need an inverter that won't break the bank/can be replaced from death due to handling/conditions/etc this is a great candidate. For the most part it works, has a good sine wave, and I believe they also do custom voltage ranges for those that want to run unique battery voltages like 4S lithium ion in the 12V-16.8V DC range.
Brillant !
Although you destroyed the unit. I will still buy one. Outstanding video. Thank You
Be sure to use the supplied links. Thank you!
GREAT REVEIW
This inverter is rock solid ! I have a 48 volt 3000 watt and it works wonders.
Don't short the output because the company doesn't stand behind their warranty.
Thank you for your honest review of the inverter. You did a very good job. But on the DC side stepping up the voltage, are they transformers or coils? Transformers will have 2 sets of windings (primary & secondary) [4 connections on the PCB], while a coil will only have one set of windings [2 connections on the PCB].
Well done!
I have the same unit that I purchased in April 2022. Yours showed voltage (60-ish volts AC) on ground.....you mentioned it is center-tapped.
It seems there are two versions out there: an International narket version? And a US market version?
My inverter is zero-volts on ground relative to either hot or neutral.
The directions also state that it is OK to bond neutral to ground IN ONE LOCATION (the inverter or the load).
That is critical if you will connect into power panel which has neutral BONDED WITH GROUND.
Imagine what will happen if you connect up your unit (60v shorted to ground) to a bonded neutral US wired residential main load center via a transfer switch.
Literaly just picked exactly this 3000 watt up from my front door. ordered on aliexpress for cheap. got it to use with a solar 24v system. my first 24v system. got 2 100ah lifepo 12v batteries and 2 475 watt solar panels with a make sky blue 40 amp controller.
It works very well, just don't short the AC output! :-)
Great video awsome.
Glad you enjoyed it Edwin! Be sure to share the video link with others. Thank you
I bought that same inverter, but in 24 volt 3000 watt in 2015. It didn’t have any vents in the cover back then. That might be why it popped one of the capacitors, I then got a 5000 watt from another company, and bought another of the first brand in 3500 watts.
Good job I would still buy the unit. Short circuit you have bigger problems the unit still did its job.
Thanks Mike! You'll definitely want to watch my other 3000W inverter review, it's a better unit.
czcams.com/video/t6MTRxYTXuk/video.html
i have been using mine reliable 48v 5kw psw for about 8 months. i decided to try to power the hvac system from this and learned about a concept called "neutral ground bond", and apparently this inverter does not support. maybe most people knew that, but not me. just wanted to share. i will be uploading a super low production video i made of this inverter under a 5.5kw resistive load and on a scope at some point, to show the weird distorted wave form it produces.
Absolutely f%^#%k%g brilliant review.. Good job sir.. I'd still buy this unit based on its ability to handle such loads. Thanks for your service.
I respect all you guys that produce YT content, so please don't think I'm hatin' with this comment. Your hair dryer uses 412 watts according to the Kill-A-Watt meter, yet when you measured using an amp meter and a volt meter, your battery was only sending out 352 watts. You either have an inverter that produces more power than is input into it or you need to change the measuring devices that you are using. The tests for over wattage was very informative, so thanks for that.
That was an error brought up in the follow-up video.
One of the most complete reviews I have ever seen. I wonder what scerieos would occur naturally that would short the unit out? It’s a shame that it blew. Hey, at least it worked for all the tests. I tried a Renogy and it was dead out of the box. I tested a $600 harbor freight pure sine wave, it came on, ran my AC for a short period. I had 2x230 amp hour batteries so it should have run at least 2 hours. After it died, it would not come on. Returned it. It’s really hard finding an affordable inverter that is quality built. I’m going to give Renogy one more try,if this one is dead or fails, done with them on inverters, thanks
I have the same inverter, but 24v. I tested out the reverse polarity protection and I lost both the AC side and the DC side displays. I changed the 3 obviously blown 20 amp fuses and the DC side came but, but still no AC output. So i pulled the remaining 5 fuses that visually looked OK and all 5 were missing the smallest piece so i wound up replacing all 8. Unit is back to full function after replacing fuses. AC output is normal. So the reverse polarity protection worked for me!
My unit was ruined short circuiting the AC output, not reverse polarity. You were lucky it didn't get destroyed.
Hello thanks for your video. We purchased a Duracell 3000 watt inverter. Then we purchased a die hard battery.
I want to make sure the battery is big enough to power the inverter
An inverter that size, I would've bought a 4D or 8D lead acid battery at a minimum, or a 200+ Ah Lithium Iron Phosphate battery. Thanks for watching! Be sure to share the video link.
I own both 1500 and 800 so far am satisfied with performance
Just don't short the output and you should be OK. Thanks for watching!
Good one, do you think the no load current draw will be more if this was a 220v system?
Hi Karry. I would think so. If you used 24v to 220v, probably the same. Thanks for watching!
I've watched many others review/test these "Reliable" inverters. You tested other "features" that were missed by some other reviewers! I, after watching several videos, did purchase the 3500 watt, 24VDC model. It is nearly 2 years old already, and by the looks of yours here, Reliable did nothing to address it's shortcomings! Just having that floating "ground" is crazy! Mine has that too and measures 60 volts like yours. I don't use mine much either. I bought it just to play with more than anything! LOL. I tried to search for the video you said were going to post explaining what "blew up" when you crow barred the AC output. Too bad you didn't have that cool LiFe battery pack then to really test surge capacity. That one 24D thought it was cranking over a locomotive engine and it's voltage dropped to under 10.5 volts with that heavy loading on it! You may have needed like 4 of those 24D's in parallel to hold the voltage over 11 for those 200+ amps inrush currents I'd believe. All I know is mine has terrible output voltage regulation. Even with 22 volts going in (remember, I have the 24 volt model), AC drops to like 109 when running a 1000 watt microwave oven. If I was living off grid, or really had to depend on a REAL "reliable" inverter, I'd pony up for a low frequency unit, one that uses a honkin big iron transformer. They have drawbacks, but for stationary use, and near bullet proof, ya, that's the way I'd go.
Glad you enjoyed and appreciated the video Curt! Be sure to check out my wide range of videos and share. Thank you

Why is the ‘floating ground’ crazy? It’s not floating to itself.
@@fishhuntadventure Thank you for your comments. Well, after watching many other presentations on the Reliable 3000 watt inverter, I learned that the "floating" 60 volts is more of a leakage than a complete connection to either neutral or hot. I found out grounding it did not cause an explosion! Sorry if I miss led you.
Hello Sir!
Just wondering what 3000 w inverter you recommend, not including this one and one that will reset after a short circuit ?
Thanks... Great info ....I subscribe to your channel
Hi electronicsNmore for the review, I've always wondered, can I connect inverters in 'series' or 'parallel' like you do cells to form a battery of inverters in order to meet my power requirements? If my question sounds silly, I apologize but I've often gotten the best insights and knowledge for 'silly' question.
I don't recommend placing them in parallel unless they're designed to be "stackable" or slave units. As for series, If you have 2 identical units, it may work.
Thanks for the video.
On one of Will Prowse's videos, he held a resister against one of the cables coming from the inverter (sorry, I don't remember which one) before touching it to the battery terminal. He said that will prevent a bad spark. The idea was to discharge all the capacitors in the inverter that stored electrical charge. By far my biggest worry here is messing up and getting a bad shock, or an exploded battery.
Also: is there a rule of thumb for the sizes of the inverter output, relative to the size of battery capacity? On one RV channel on CZcams, they said that every 100 watts of load plugged into the inverter. requires 10 DC amps from the battery.
Thanks again.
Either side works. Not really necessary unless you're in an explosive environment. It needs to be high wattage and maybe 50-100 ohms. An inverter pulls roughly 9A DC for every 100W AC.
i think you misunderstood what will was doing with the resistor. he was using it to control the current into the capacitors by limiting the current through a big resistor, so the caps will fill more slowly rather than all at once creating the big spark.
@@jasonbrown467 exactly
The resistor stops contact damage from the spark and keeps you from getting tiny pieces of hot metal thrown at you
Luv Ur Expertly Detailed Review‼️
What minimum Capacity wd U Reccommnd to Recharge a 24v Jazzy W/C - 8A Battery❓ Thx
What are the specifications for the AC charger?
As other said " Great Video "
It is a solid inverter undoubtedly.
An unloaded circular saw. But you made up for that with it with the short circuit test that should be done on all inverters. So far you're the only CZcams reviewer I've seen do it.
Using a sharp blade on the circular saw will not cause much of a rise in current.
@@electronicsNmore Until you cut something. The harder the better. Or lock, or jam the blade.
@@bearchow1929yeah, there should be a sizeable difference in power draw when cutting vs free spinning operation. Not much work done in spinning the blade in free air vs. actually cutting wood.
Very helpful useful excellentful every ful on earth for you and your review, thank you ful😅
Wow, this video was very informative, well thought out and explicit. “KUDOS” to you. Did you have any feedback from the company? This video🎥 is rated ⭐️⭐️⭐️⭐️⭐️ PS... THEY JUST SHOT THEMSELVES IN THE FOOT, I WILL NOT BUY FROM THEM! Followup, I just read the comments from others, hope the company compensates you in some way.
Glad you enjoyed it. Since 2014, I try to make my videos as professional as possible. Other channels sit in a garage filming the video on a messy bench or lab, ramble on, all kinds of background noises, etc. If you don't short the output, it's a very good inverter. Thanks for watching!
electronicsNmore - Thanks for your response. I do understand what you are saying about the “SHORT”; however, you spent valuable time to cover every angle, explained what and why you were testing the product and gave positive feedback throughout the entire video... then “BAM” the Power Inverter is useless, you deserve a replacement. I am sure some folks will go buy this inverter as a result of your video thus more profit for the company. Your wisdom shines, have a “GREAT DAY”, everyday!!!
I did enjoy this video for maybe a different reason than anyone else...I bought an old welder once at the auction for $18...the cord needed changed so while doing that I noticed that this thing was so old that it has white copper windings (part silver)..so the potential inverter had to be able to run this thing...well I got to thinking after I saw this video..what happens if the welding rod sticks ? Pretty much a dead short there...kinda like you did..so while I had that on my mind I went and ordered a 24 v 2000 w Aims inverter/charger...the thing has two GFCI outlets and the hardware connection and I thought..that's all yours needed and it woulda been okay...so I thought it might save on your fuses and things to have those...I found a coupon for 15% and got mine for $653...its a lot of bread but I figured its better than having to buy another one when I least expect it...I put a 1450 watt load on it when I use my air fryer and it just does fine..I used two #2 welding leads on each post..each one hooks to 4 batteries in series/parallel for 24 v and they don't even get warm usually although that might change in August lol
2ga isn’t quite big enough. You should probably be using 1/0ga. Heck, I used 2/0 on my 1200W/12V inverter
@@fishhuntadventure Oops ...mine is 24 volts...there are 2 pairs of #2 cables on the batteries, so it's actually equal to a 1 / 0 cable, which is what it calls for. I have 18 batteries now. I used a pair for the eight 90 amp hour batteries, and a pair for the ten 105 amp hour ones. I just finished rewiring the battery bank with new #2 welding cable, it carries 195 amps. I have used the oven for an hour, and there was maybe a few degrees of warmth in the cables , but it was very slight and hard to feel any difference. The amps are less now because the batteries are always charged, so higher voltage, lower amps. My uncle loaned me his 2000 watts inverter, 12 volts, before I got mine...way more amp draw...that was the reason that I decided to go to 24 volts. After I got all these batteries, the voltage never goes below 25.0 volts, even after two days of no sun and constant rain. The welding cable that I used carries more amps than regular stranded wire. With 18 batteries, each one is only pulling 25 amps or so. So the batteries will last longer, and the wires stay cool...sorry if I wasn't clear earlier.
Depending on how bad the damage is, you might be able to replace the AC driver with your own.
Just found the problem. :-) I'll make a short video showing it.
Can somebody please explain to me, how is it drawing 350W from the battery and giving 410W to the dryer? (Something to do with the powerfactor? The way output power is measured?)
Very nice and detailed review, thank you!
I had a calculation error in the video. The updated video mentions it in detail. Thank you!
Hello thank you for your video. I would like to suggest to a test. I have a similar inverter I have noticed that when I use the outlet tester it shows as open ground even with a ground cable properly connected. That would help catch problems with the circuitry. When I did some research for this problem I found information that someone posted indicating that the customer should fix a couple cables. I bought mine over a month ago from Amazon
Most inverters don't have the ground, usually you connect the receptacle ground pin to the inverter's metal housing, and the metal housing to earth ground(a metal rod w/clamp)
@@electronicsNmore yes i understand but many do have outlets where you can plug in your devices directly. In my case even that plug after connecting the chasis to ground shows open ground which create an unsafe situation. I have received an email from the manufacturer indicating that there was a problem with the device.
Hopefully because it was a review of their product, they'll send you a new one.
Perhaps the output breaker doesn't trip fast enough and burns out the FETs or something. If it's FETs, easy replacement, relatively speaking.
Agree, as of now this video was a HUGE waste of time. No views, and no product as compensation. Honesty pays. LOL
@@electronicsNmore I wouldn't say it was huge waste of time. For one, it's not very old at this time, and two, for those of us who rely on non-affiliated reviews, this will be valuable for years to come 😎😉
@Korishan I hope you're right about the success of the video in the long term. I like making videos, but YT is a full time job, so without compensation the channel won't survive. I can't work for free while other people upload "goof off/clickbait" videos making thousand per week. The wrong people are being compensated. Honest people that take the time to help others, they're the ones that should be making the money. Our society is backwards.
@@electronicsNmore Have you tried doing some LiveStreams over on twitch? That might help balance out some of the income issues.
Tho, most of your videos are long in the making for only 10 or so mins of actual content.
@@electronicsNmore I don't know if you use Patreon, but you might do well to have a patreon account. Personally, I will never use patreon, but I do financially support some of the people I follow through a PO box.
Also, it is getting more and more difficult to make money off of youtube. Even videos with hundreds of thousands of views get demonitized and otherwise cheated. YT stole thousands of dollars off a YT user named Mister Metokur. He had thousands in superchats just outright stolen by youtube. CZcams does that a LOT.
But even channels and videos which are not getting demonitized got hit hard by the adpocolypse starting a few years ago. With YT loosing hundreds of millions of dollars, that is not likely to improve anytime soon.
Thanks for the video. Is there a comprehensive way to learn about the electrical components and principles involved in off-grid solar, so that i don't fry something out, or worse, get an arc flash?
It's very simple to set up a system. You can use the setup shown in this video, along with a MPPT charge controller that can handle the level of current supplied to your battery/inverter from your solar panels. Just be sure to use the correct size wire, use a fuse at the POS post of the battery, and keep the runs short as possible. Using a higher voltage system(24/48) will allow smaller wires to be used from the solar panels. You can find solar system wire size charts online. Thanks for watching!
@@electronicsNmore Thanks for the answer. I hope this isn't a dumb question,. but you only need the charge controller connected when you are charging the battery, but not when you are only drawing a load from the inverter? Is that right? Thanks.
@@rootcanal7188 When you draw a load from the inverter, at the same time the inverter draws current from the batteries. The charge controller needs to be connected and functioning at all times. It prevents the batteries from deep discharge from the load by allowing more current into them from the panels. But to protect the batteries from discharging too low and damage them, an additional battery protector can be installed between the batteries and the inverter. I have a Victron Battery Protector with integrated Bluetooth that can transfer up to 100A for 24V (2400 watts) and I programmed it using their free Android app to disconnect the power from the batteries to the inverter if it discharges to 24.85V which is about 40% discharge and reconnects power to inverter if batteries recharge to 26.10V.
@@MoooHamMad Thanks very much for the thorough explanation.
Fuses are very "slow" protection devices. Something else (usually a MOSFET) will let go before the fuse blows. So they are kind of useless unless you have a direct short form the positive input lug/wire to the negative input lug/wire.
If you size them right, and use a fast-blow type, they're very useful.
@@electronicsNmore - I disagree.
First, I don't believe that fast-blow fuses exist in ATO/ATC packaging.
Second, fuses can "hold" at much greater (even 100% over) than their rated current for SECONDS !
Third, over current can kill a MOSFET in microseconds. The fastest fuses take millisecond.
Fourth, if one MOSFET fails, its load/current transfers to all of the other MOSFET instantaneously and overwhelm them and they all die.
I have seen a lot inverters with blown up input MOSFETs. I have yet to see one where the fuse(s) blew to save the inpout MOSFETs. Designing some type of very fast electronics that would protect the input MOSFETs is probably not cost effective.
If they are useful, why are they so difficult to access ?
Great video. Did you ever repair this unit.? If so what part failed?
Hi Lee. No, the company never sent the parts.
@@electronicsNmorewhat part did it require?
Can you do pek power surge test like multiple motor at one time, all inverter I have so far can't run two vacuum at one time even up to 8000watt, it really frustrating.
According to the Amazon listing, the AC terminals are as follows:
Line (Hot) - RED
Ground - YELLOW
Neutral - BLACK
That’s an absolutely ridiculous assignment of colors. Unless someone is really paying attention, they’re going to wire it wrong and possibly kill themselves. Good luck to the next guy that comes along and has to service it, without the manual. (The terminals don’t appear to be marked, either.) The manufacturer needs to change this!!!
Agree. The color choice not correct. Yellow is always a "hot" color. The black and red are OK because each leg has power to make 120v, just like you use (2) 120v legs in your home to make 240v. The clear plastic cover is marked. Thanks for watching!
think of it as a 3 wire industrial setup: there isn't really a neutral (i.e. a grounded conductor that normally carries current).
Except maybe for some 3 phase systems which sometimes use red/blue/yellow combination to represent each hot phase, I battle to see how anyone would mistake the yellow wire as a hot wire especially on a single-phase inverter that needs to be earthed anyway. Ground/Earth is usually green/yellow. If it's not a combination of both colours (ideally), then either should still suffice.
Live ought to be brown or red, and Neutral blue or black. So long as Live is represented by the presence of either brown or red, then one should immediately recognize yellow or green as ground/earth, especially if it's the odd one out.
In DC systems, black usually represents negative, and red positive, and because red is often substituted with white, intuitively one would expect that the same would apply to AC systems, namely white could represent Live and Black neutral, yet in the US they use the exact opposite - black for live and white neutral, which truly boggles my mind!!
As with everything, lack of standardization can be extremely frustrating and sometimes even dangerous/deadly... When in doubt, bring out the multimeter :)
On a slightly different note, I'd be curious to know whether or not these Reliable inverters, which seem to have a floating neutral, would take well to bonding Neutral and Earth together? keeping Neutral and Earth unbonded could pose a safety risk as you don't really want a potential difference between them, especially if you're going to be feeding directly to your house's breaker board. Most Chinese inverter designs don't tolerate this at all as it causes a dead short. Taiwanese-made Meanwell inverters do allow it, though I'm not sure what difference in construction actually makes that possible, but I'm guessing some kind of galvanic isolation on the AC output stage. Indeed most inverters (even generators) don't ship with a bonded neutral or GFCI/RCD/ELCB breaker as there are cases where that would be undesirable..
@@DimitriPappas I think most north-americans do not associate yellow with grounding, just green.
electronicsNmore - You can’t call this a two-phase, or split-phase system, no matter how it’s configured. Also, the black ‘neutral’ and red ‘hot’ are legacy UK colors, which are no longer in use for new installations. They now follow the IEC standard, along with the rest of Europe, with brown for ‘neutral’ and blue for ‘hot’, to avoid any confusion.
I also understand how they are using the ground, like the neutral between the two legs of a US residential breaker panel. However, this is just completely wrong, on so many levels. Ground is ground. The ‘ground’ on this inverter is like a neutral, with a 60 volt ‘leg’ on each side of it. The ‘ground’ wire should NEVER carry ANY current, unless there’s a fault. In my professional opinion, this inverter is just poorly designed. I would be embarrassed to design something like this. (Yes, I’m an EE.)
Being that these are also made to be used outside, they’re wholly inappropriate for use with a GFCI adapter, with a 60 volt potential between hot/ground, and neutral/ground.
Again, I fully understand how this inverter works, but that doesn’t mean that it’s safe, or designed well. Again, ground is ground. It should never be used as a neutral. This is just a cheap, but dangerous, way to do it. I’m almost afraid to ask which terminal, if any, is tied to the case of the inverter.
We can agree to disagree, but this isn’t a matter of US vs. EU or UK standards. This is a matter of safety.
Thank you for showing this. I have the 24v 800w model, when I use a pedestal fan on low (50w kinda) after a while it just cuts off, back on and off again, Batteries are at 28.9v, I check and notice the cooling fans didnt kick on, so I turn it off and on and they kicks on for about 30seconds and runs fine for another hour, can I add two pc fans (with a 12v power brick) and leave them on 24h, thanks to you I see its an overheating problem. But it least it didn’t burn into oblivion like my last cheap inverter (dead fans)
I thought I heard you said something about the 24v version is better due to hooking up smaller wires? I’m planning to buy the 36v version and hook up tons of Ryobi 40v batteries in parallel. What type of wire would you recommend me hooking up the batteries onto the input?
Higher input voltage means lower input current, which means smaller diameter wires. You can find charts online for DC wire ampacity for desired length.
Can a quick-fix solution to the ending concern be puting an MCB after the inverter outlet (before household load)? Thanks!
Yes, I'll be showing that soon.
In case anyone doesn't know the reliable inverters typically have 60v on the neutral and 60v On the hot wire to make the 120v you will get shocked on either side. And it interesting trying to wire it to a breaker box. Because even in the off position there is still 60v on neutral 😒. Many other inverters are the same👍
In order to be safe, just like 240V requires (2) single pole breakers with a common trip, you can do the same for the 120V, use 2 breakers at 60V each, of course the panel couldn't be connected in any way to your AC mains panel. Thanks for watching!
Weird you came up with this one . I just purchased two of these inverters in the last two months. A 24v for me and 12v version for the mother in law. These were the only units I could find that were capable of producing what they are rated for. I've seen ZERO negative reports on these units. Would like a follow up on the unit you shorted out and failed. I would have expected internal Line Fuse to pop.
Using Nissan Leaf Li Ion Cells (12ea 4P 6S) initial battery voltage of 25.00v. The Low Voltage alarm kicks in before my batteries are actually in a low voltage status. My run time is a bit short due to the way the voltages match up but works quite well. Disabling the SonAlert I can run until the unit does in fact shut down and prevents battery damage.
The built in sockets are not wired for higher amp loads. Use the out board wires for anything over 12A.
You're correct! The testing was done before the unit were opened for inspection. I figured the AC receptacles and terminal block had the same size wire. That also explains why the voltage drop was observed under load. Like I said in the video, it's a great inverter, just don't short the AC output. I found the problem just a minute ago, I'll be making a very short video to show it. Thanks for watching!
You said the "built in sockets are not wired for higher amp loads." If that is true on this inverter, then it is not a good design, I have a 3,000 watt inverter that you can pull it's rated capacity from the outlets alone. Another inverter is only 2,000 watt and on this one it has a 15 amp GFCI outlet, if you need more power, it has a terminal plate. Don't want to sound like these are not good but for me, you should not be limited to current draw on the outlets on an inverter.
Very interesting ! Thanks for the review.
I am disappointed that the output voltage dropped below 100VAC with heavy loads. May the drop out input voltage should be closer to 11.0VDC. It would be nice to see how 2 of those giant batteries would drive that inverter.
I don't think you can pass judgement on the MOSFETs without testing them.
After opening the unit, i saw why the voltage dropped. The full AC output was using 14ga wires. If you replace with #10, I bet it stays well above 100V.
Do they have a 240v output version that is also center-tap ground like this one? 240v split phase... :D
They sell a 220V or 230V version. You choose the frequency and input voltage. The website is below.

Great video, I enjoyed the tests. I have a Reliable3000W and I'm thinking of reversing the cooling flow for the hot air to rise due to the position it is installed.
Do you think this inversion can damage the equipment?
Congratulations and thank you.
I wonder what would’ve happened if you had actually DISCONNECTED it from your battery. Would the short-circuit protector have reset?
I did that something by mistake. You need fast fuse on the AC side. Slow opening fuse won't help .
After that.. I did got 4000 thousands watts GIANDEL .. No problem with that one.. I put fast opening fuse 30 Amp at the AC output ..
So if you run a 3kW load, it will be dissipating over 400 watts of heat? I'd like to see this thing tested at 3kw or 2wk on a continuous basis. I think it is fairly likely to overheat and shut down. To me it seems like overkill for a portable unit with 120v outlets.
Only way to perform that test, would be to have at least 2000W of solar panels connected to the battery.
now how do we fix that when that happens?
how to troubleshoot and track down the failed components?
Would you recommend removing that silicone heat transfer film and installing good old thermal paste?
The best to use would be a silver containing thermal compound, but they usually don't burn up from heat. High inrush and short circuits are what destroy the mosfets.
@@electronicsNmore Thank you!
just noticed something weird at 13:41 352 watts coming from the battery but 412 watts coming out the inverter, that means the inverter is giving you an extra free 60 watts that is coming out of thin air . . that also means your equation was backwards and it was operating at an efficiency of 117% !!!!!!!!!!!!!!!!!!! did someone say overunity .lol . . . my guess is that the power factor threw off the reading and were looking apparent power not true power . if the inverter is supplying 412 watts and is operating at a typical efficenty of 90% it would be pulling 453 watts from the battery . . . either way it was great video and extremely detailed. im really curious about it being center tapped .. . . curious if you could buy a 240 model and use it as a split phase set up
I clarified that in part 2!
@@electronicsNmore sorry i just noticted your pinned post. .
good review! but becareful dont touch heatsink or anything inside when its running!
That's a big battery, is it just 12 volts or what? Did you check the waveform output of the inverter? Thanks
12v
👍👌❤️🇨🇦, gr8 review
Can you test the saw when cutting please 🙏
Kink of like to see the waveform while under a couple amps of motor load. Table Saw?
Too late now. LOL Watch to the end. I tested other inverters and observed that the waveform degradation under load was at a minimum. If I get it repaired soon, I'll test and report back. Thanks for watching!
What inverter brands do you recommend? I need a 48v 2500 watt inverter.
The system in this video, but don't short the AC output unless it's protected with a fuse.
Did you make sure to bleed caps off? Does it work now? thanks!
Working on it today, I'll give updates. Be sure to share and rate thumbs up. Thanks!
Wishing for a good PWM current shunt OC shutdown logic saving your 16 MOS switches.
What size fuse do you recommend from the battery to the inverter I have the same inverter but it's 5000w and I have eight 400 amp hour batteries the gel ones
