If there’s one thing I can’t stand more than anything else 😂 With a white board behind you😂😂😂😂😂 Can’t make that shit up😂

Had my Powerwall 3 for a week now. Quite happy so far

This guy in pajamas forgot to clean up and us not an authority on the subject.

Great info thank you

Thank You for All that you are doing for our Planet Earth.. .. Peace.. Shalom.. Salam.. Namaste 🙏🏻 😊 ✌ ☮ ❤

In NJ for install 4 5p batteries companies want 38.5k $ this insane. 2 tesla powerwall 3 cost 22k $. Same chemistry, more capacity and more output. One thing is different tesla powerwall 3 can not be charged from generator.

A great video, thanks for taking the time to put all of these new features and capabilities of the Powerwall 3 on a video. Perhaps the single biggest and in my view most important, features is that huge peak power capability. I live in the desert and have two AC units. For everyone else's inverters operating in backup mode, something has to be done to prevent the inverter from shutting down and going off line if both AC compressors start up at the same time, particularly if the OAT is over 100 degrees! I also have couple of quick comments / questions. On the mid circuit interrupters, in round numbers solar panels put out around 50 volts around midday, two in series output lethal voltage, so wouldn't the mid circuit interrupters need to be placed on each panel, not on every two or three? At least according to the Fire Dept. where I live there shouldn't be any lethal voltages when the system is in rapid shut down. You also said that you would have to buy enough Powerwall 3 units to power the whole home during backup. Doesn't it have any sort of load management / load shed capability? It seems that a good portion of the competing manufacturers either have automatic load management or are working on it. I would like to see another video on the Tesla App and in particular how it interacts with the Powerwall 3.

Great Vid ! Gracias Amigo !😁

Really enjoyed a lot of the points you made in this video. Enphase is gaining more and more popularity depending on what the individual's needs are. With the ever changing solar industry, it's not always easy to keep up with new trends and equipment. Very educational piece. Keep it up!!

How am I getting a Gateway 3 installed with my PW3 ? I have an existing system with a SolarEdge inverter and optimizers. They tell me it can be AC coupled?

I have 4 Enphase 5ps installed. Calling it good for the next 20 years assuming I live that long.

I just looked at Tesla website, if you go to buy a power wall it does not say definitively what power wall version you are buying. Anyone know why?

Great video. Thanks. 👍

Wow. Talk about major limitations. Not even compatible with there own older systems. Just a way to force you to buy more equipment exclusively from them.

Can we AC and DC couple at the same time? I think yes. What are issue will occure during the the setup? As DYI Trying to see what benefits for both system intergrated?

How about an install on a house that already has solar but no storage? Is there a way to install a PW3 so it charges off excess solar during the day and runs the house in the evening/night, without tying into the current solar system?

Very good video. Would be great if you can do more on microinverters such as install steps or components needed like dc/ac disconnect

wholesale sol-ark cost $5500

Nothing new, Tesla is just catching up to the competition.

I have been into Solar for Years and I am an EE. Some of these comments are just missing the point completely. This is about safety and what the inspectors want to see. It does not matter if your PV is limited to less than the Amps rating. It does not matter if your batteries are limited. Every Inspector knows that the Amount of Panels may increase and more batteries could be added later. They are only Interested in what is the Maximum the Inverter, Wiring and Panel box can handle when put together. This was a good video but could have been better if the Buzzer sound was eliminated.

I'm glad Sol-Ark has dropped the made in USA advertising. Also, I've seen too many vids of the Sol-Ark inverter being underpowered. I do like Will Prowse (sp) recent video of the EG4 12k showing the inverter able to start 4 compressors and a car lift without tripping the inverter. I'd love to see if the Sol-Ark 15k can do that. Also, pricing is a huge deal. Lastly, the ferrite filters they add to the panels as an EMP protectant I would have a hard time relying on. I would go with EMP Shield's products, it's much less expensive that paying to EMP hardening the Sol-Ark inverter and you can get all the proper protection for less cost, ie protection from the grid, the solar array and the battery.

I’m pretty sure Tesla has had a meterbase mounted Backup Switch for 2-3 years already. Is this Backup Switch you’re describing different from that one?

your talking solar not the inverter that is doing the dc to ac

Do you have a source for the 20,400 watt peak for the 18kpv, I can't find a source for that and having an official source for that would make permits much easier for a project I'm working on.

Where do you get that 10 second power number for the 18kpv? I've been unsuccessfully looking for an official source for a peak output as part of dealing with some compliance issues if I want my ac on it as I'd need the peak output to be above the lcked rotor amps of my ac. If there's an official source for that 20,400 number it will save me a lot of work.

Build Country of Origin for both...................CHINA

when the dc expansion packs come out, is it possible to add just that to enphase panel system ? or do we need the pw3 and the dc pack can only be added to an existing pw3 ?

Informative Solaredge Ecosystem. Nice work!

17:00 The Tesla backup switch, eliminates relocating loads to a Backup Load Center. If there’s not enough space in the main panel for the PW3 breaker a generation load center might be needed. 20:05 The PW3 can work with a Generac backup. Main panel, Gateway, Generac breaker in Gateway, then Generac relay, then Backup Load Center.

MAJOR PLUS for EG4 is that in can be installed right on top of the cable trough, because it does not have a requirement for any space at the bottom like the 6" for the Ark-Sol.

Unfortunately this data is still incorrect. The max usable PV of the 15k is 18kW (with batteries). Without batteries it's only 15kW like your whiteboard shows. The maximum continuous inverter output without PV is also not a fixed 12kW. The maximum DC discharge rate is 275A and the output is based on that. So lets say the batteries are currently at 52V, after inverter losses it'll be able to output around 13.5kW. The 18kPV has a 250A max battery discharge rate so the maximum inverter output ends up being around 9-10% less than the 15k at a given battery voltage.

The inverter is the heart of your system, Sol-Ark cost more best is has proven itself in the industrial market and is well made. I had nothing but nightmares with 3 Growatt 5000es and Signature Solar did not help. I used to wake up at night to make sure they didn't kick off and I had to restart them. Now with the Sol-Ark 15K running the while house including a 5 ton heat pump, I have had nothing but peace of mind. The customer support is top notch and they have moved their monitoring servers to the U.S.

I have a question about the 200 amp bypass for the grid connection for these inverters. With grid on, and the loads are exceeding the inverter output capacity, will the grid assist in powering the loads to prevent an inverter over current shutdown situation? TIA!

Hi, great explanation, im about to buy a 6.9kw array on an East facing roof. I have been offered either a 5 or 7kw invertor for the same price. Which one would work better, i live in the UK so not especially a sunny climate. Im also having a 10kw battery if that impacts anything. Many thanks

Great comparison. I would also pay attention to amperage. Sol-Ark MPPTs are full sized, not irregular amperage. This means greater design flexibility on the roof and not pushing to the limit for those larger PV arrays. You could call that max PV size conservatively specified as that line item isn't part of the UL certification. The Sol-Ark battery charger is also more powerful, which makes a big difference when wanting to use the inverter at maximum 12kW capacity throughout its life. Finally, there are a few features that might be considered a tie on the whiteboard. The winner of the tie should be the company that innovated the feature, not the one that copied it.

Adding 2 PW3 to my existing Enphase PV system. Would not give up my individual panel monitoring. But the PW3 is a lot of bang for the buck. Installed after all credits and utility rebates OTD for $19K. My second PW3 is the Expansion unit. I'll have the best of both worlds.

Gotta tell you that this video is pretty much a waste of time. A bunch of numbers written on a white board. Then a price comparison. Absolutely of no value to a site that wants to set up a battery backed grid tied hybrid system. But you keep click fishing.

I need some help figuring out my solar needs and what I build myself with an electrician. Thank you

Looks like a great battery and it comes with a 6 string inverter! I was thinking of getting micro inverters for our apartment but if I can save money and still have just the battery and a gateway in the garage then I'm happy. Good to see they have rapid shut downs.

Not having Micro-Inverters, is a deal killer for me.

Nice overview and thanks for correcting previous info. That's a righteous thing otherwise, bad info piles up.. Hey, so one thing I'm always interested in is where the company is based and also where it's manufactured. I know, I can look it up but I think it's important in a side by side comparison. And besides employing my 'neighbors', it also may have warranty implications. I always prefer to buy American, except for an occasional Honda motorcycle... Thanks for your efforts! N

Why would different strings need to face the same direction? PW3 has 6MPPT connectors. Wouldn't each string wired to different MPPT's not care which way the other one is faceing?

I was deciding last month between these same 2 inverters... I ended up going with EG4... a MAJOR factor was the friendly support from their tech support people, answering questions before the purchase and this continued after as well

For the love of all that is good, please put down the pointer! It's really annoying.

Good video, you know your stuff. Please put down the pointer when you talk bro!

Sol Ark hay a better tech support. EG4 has a terrible tech support. I have experienced this.

True, hopefully they will be around for a long time. They seem to have lots of sales.

Okay , these are the comparisons numbers for now , could change!

How are you protecting electrical workers from backfeed during storm restoration effors?

How much energy (in kilowatt hours) can the power wall 3 actually store?
