I like how you shared your mistakes, and the learning process. Thank you.
Wow, I am so thankful you clearly explained how much energy can be lost just through the cheaper charge controller and battery. Decided to go with an MPPT and AGM battery. The cost is really not that much more, Thank you so much for allowing others to learn from your mistakes, this is the good side of youtube !
Thank you for the kind feedback. I’ve completed the fourth and final version with a number of enhancements - the video will be out in a few days. It may give you a few more ideas. Good luck with your project!
I can see you've put a lot of work into this video. One of the most informative, straight forward explanations I've seen. As an electrician with an interest in this kind of thing, I find myself having to explain all of these concepts over and over to people who are setting up off grid supplies, or RV's. From now on I'll just send them a link to your video. Great work.
Always nice to hear from someone else with experience. I hope the worksheet helps your people plan out a system you’d approve of. And it’s alway great when someone recommends the video - many thanks!
AMAZING JOB !!!, Ive been a solar contractor developer for almost 20 years
I wish I had some insight or information to add, but you have nailed it
The equipment lists and calculation spreadsheet is very helpful
Thank you
Thank you. Finally a video that helps me understand why our off-grid system keeps killing batteries. 🤔 Really appreciate your calculator sheet.
Awesome Video and instructions, Thanks for doing all the R&D and for everyone to use your design.
Best DIY Video Ever.
Thanks,
Jordan
This channel is awesome. Hopefully you'll get active again. I'm going to try to give it a go soo. I wish I had found this channel sooner. Thank you for the information.
LOVE IT !!! I've watched a couple of your vids on this system and will definitely be building something very similar. When I'm done with the dozen or so projects that are currently taking up all of my time, I will start this one and get back with you on a couple of questions. Thanks for the in depth videos and keep them coming !!!
Great job! This just gets better when you upgrade info!
Thank you so much.. Your discussion of efficiencies of each component was an eye opener.
Subscribed straightaway ..................Very much appreciate you're time and Guides Im going to build my own with the fantastic help from you're Design Guide Worksheets
best help I have seen
Subbed. I'm converting a cargo van for camping, arb fridge, charge phones, laptop, tablet lights at night. I'm learning a lot from this, I'll use two batteries
Thanks for the subscription. I'm just finishing the final build on the generator, and I'll post a video on the build in a few days. I'm toying with the idea of a major solar upgrade on our RV -- I think the diesel generator could be relegated to use only in the most extreme situations. If it happens, I'm post video...
I just wanted to say thanks for putting in the work to explain it. I'm going to build one for my overlan ding adventures in my truck but I want it to be more useful then charging just a cell phone. Thanks, now I have a idea of how to do get it done.
Thank you- this is so helpful from a novice perspective. Keep the videos coming.
My pleasure. Thanks for the kind feedback.
This is an excellent and informative video and thanks for the worksheet download. I have been wondering about making my own solar generator and this is all the inspiration and how-to info I need. thanks very much. First rate stuff.
Happy that it helps you get started, and hope your project turns out great!
Thanks! I have been thinking about building something like this. Your videos are well designed and I will use them to build my own system.
Thank you for sharing, learned a lot, saved me time & money to experiment and build prototypes. Planning to build the system on a wood rack with provision for mobility using a dolly for refrigerator backup use. Already have system built in 2012 for a tankless water heater using ExelTech XP1100 inverter and 31-GEL Trojan battery. It is a permanent installation next to the heater.
Tried to run the refrigerator with our latest power outage using an extension cord. Refrigerator run for about a hour, but due to the high surge current during startup, the system will no longer run, the inverter shuts down, but it runs the tankless water heater with no issues. Inverter is rated at 9.4 amps, the surge current MAYBE as high as 6 times the running current of 1.46. Calculated surge current is 8.76 amps.
To solve the starting current issue, plan to use an ExelTech XP 2000 with an output current of 16.7 amps.
Will use your Excel spreadsheet to calculate the number of Trojan 31-GEL battery to use.
What a cool project! You really did your homework.
THIS is exactly what I've been looking for. Well done & Thank you!
My pleasure. You might like the build video for the final version of the generator which details the build process and includes a parts list, wiring diagram and engineering worksheet to help choose components. czcams.com/video/QZYAAatdlmc/video.html
You've helped me understand solar better. Thx
Glad to hear it’s helpful. (cool handle, btw)
wow that was awesome, you really explained that so well, even i think i got most of that.love the diagram
Awesome info! Thanks for your edification of my limited knowledge!
Having this available for use on job sites where there is no power is what I like about this setup.
Great idea!
Wow, Now I understand more. I have a 3 unit 200 amh 12 volts deep cycle solar master by motolite and this video really helps make it more efficient. Thank you and thank you again. Also, in the Philippines, I can buy a 12 volts pumps and lights and even refs, I do not know if we have this in the US but at amazon that is where I bought my 12 volts lights, that I do not to use the inverter which can really lower inefficiencies and cost. Please make more videos like this, educational, fun, entertaining and enlightening, More Power and God Bless you.
Thank you so much for the kind feedback. You’re SO right about using 12V devices - gets a lot more utility out of the stored energy. I’ve just finished the fourth major version of the project, and collecting the measurements I’ll be reporting in a new video next week. Stay tuned...
What an amazing video. I watched this one and the original. It would have been good if everything worked right from the beginning but learning from one's mistakes (and someone elses's) is really helpful. I'm glad you were able to improve on the original design.
Best & most helpful DIY Solar Generator Video I've seen so far. Great Job !!!!!!!
Thank you so much -- glad it helps.
Excellent series
Thanks - appreciate the comment.
New to this solar energy thinking of one for our camp in the woods very informative.
You might like the build video for the final version of the generator which details the build process and includes a parts list, wiring diagram and engineering worksheet to help choose components. czcams.com/video/QZYAAatdlmc/video.html. Let me know what you think..
Very thorough & well documented. Many thanks & much appreciated.
Glad you enjoyed the video. Thanks for the comment.
Karlosss please help with the documents the site is down
thanks, looking forward to seeing more of your videos.
Wow your projects is so beautiful and interesting
Some very good info thanks for sharing and God bless you always
Thanks for the kind comment. Blessings...
Very good job, awaiting version 3.0 to start my solar generator project.
i’m just assembl(no the revision 4 model now, and expect to shoot video on what I think will be the final version. It incorporates the best of the ideas viewers have generously offered. I’m very happy with the result, and will be posting a builder’s guide that shows how to make it.
So much useful information that's correct, and he didnt even ask us to like or subscribe 😥
I miss the old CZcams
Great video/content sir, thank you very much for sharing.
First of all, I want to say thank you. Your videos and ideas are awesome. The second reason I am here is to ask you something. I am not sure if you would know but its worth a try. So in general houses have a grid tie system or can be completely islanded without an issue. When it comes to making the house both grid tie and off grid functional, the battery based grid tie inverters cost is a HUGE deterrent. I have heard that instead of using a Battery based grid tie inverter you could possibly use a generator. We are building a solar powered system so we wouldn't want to use a fuel generator which is why I stumbled on your video. As you know grid tie inverters are designed to detect the main power grids frequency and/or voltage if it doesn't detect it will shut off. When a blackout occurs this is a problem so you would usually design your system with a battery based inverter or a generator as well to fool your grid tie inverter into allowing the continued flow of energy. (take a breath) So the question is if you think that this generator you built can be used to substitute that generator/battery based inverter. I am sorry if this is a silly question. In addition, you should know that this is for a project so I don't need to power up an entire house now, but it must have the potentially to feasibly power up the load in an entire house in the future.
Let me start by saying my knowledge of grid-tied systems is limited, so it will be important to gather advice from other sources. A fuel generator system would, in my opinion, be of limited utility due to the fuel volume and storage requirements. My 3800W generator runs for roughly eight hours on four gallons of fuel. To provide continuous power for a week would require more than 80 gal of gasoline, and it would need to be replaced about once each year to ensure it was OK to burn when needed. If your solar / battery system is to run simultaneously with grid power, you’ll need some kind of synchronization capability. If just for standby emergency power, then a transfer switch will be necessary. Without knowing more about your specific needs, I’m not sure this information is particularly responsive, but others here may have some suggestions 9f you can outline what you
d like to accomplish.
Desert Prep first of all thank you for responding. I might put this question on hold for now. We found a device that might help us so I'll come back if needed. This solar power generate wouldn't run all the time It would be more for an emergency. I really appreciate you taking the time to respond, thank you again!
very nicely done..... thanks for doing this video
Outstanding presentation and build. We need these in the desert, but I can see using this while I'm travelling too.
Thanks for the kind comment. A number of people have spoken about adapting for RV use, and I’m toying with the idea of upgrading the DC power system in our coach...
Great idea. A unit that does not include the inverter will provide more power at lower loss.
We did something similar for NASA years ago, only powering a number of DC devices, from Laptops to VHF Transceivers, and GPS units. This was before cell phones really took off. I will rethink that concept, based upon your unit.
To get higher DC voltages we had multiple deep cell marine batteries in series, with taps in parallel for 12, 24 and 48 volt outputs. My personal budget won't support more than a few, but I like your AGM option.
Much more research to do for a second unit, but I'll start with your model.
Your spreadsheet is a wonderful start.
The multi-tap idea is brilliant. The new generation af MPPT controllers are almost magical - gracefully and efficiently converting higher-than-needed voltages into optimal voltages at increased current. Two 12V AGM batteries in series could be efficiently charged by two panels in series, and you could dedicate certain devices to each of the batteries. (Perhaps one battery would power the fridge alone...)
Awesome video! Thank you for sharing your design. You have one new subscriber to your channel.
Wow, I saw your 1st video & this behind it.....lol, truly you've done a lot of homework($) ! I started
all this work but put it off because of low funds. thank you for all the information! For people with
little means you'll help us to get it close to right the 1st time out.
peace
Thanks for the kind comment. You make a great point about getting it right so there’s no money wasted. I’ve just finished the final version, and the video will be out in a few days. Good luck with your project.
please help with the documents the site is down
Thanks for sharing awesome information
Great work. Thank you....
Nice work
Excellent video!
Great stuff.... thank you
impressive
One other thing to keep in mind is 100 watt panels will never produce 100 watts of power outside a lab. You need to take those inefficiencies into your equation too. Also if you're not tracking the sun with your panels that will be another loss to take into account.
It's looking to be a very good setup.
Good feedback. I’ll add that to my consideration for the next round. Appreciate your comments.
Ok I'm done with solar, saving in my building ideas and moving on. I subbed just in case you do something else offgriddish...Thanks
Nice job on updating your previous
I wanted to know if you recommend the Inverter , looking to get one but could not find any reviews, thanks.
I like the inverter a lot. Works very well, quite efficient, and love the status panel. It also has some pretty good protective capabilities, including an alarm when you’re driving your battery to damaging low voltage. The price is quite reasonable, and the dine wave is very good. I’d definitely buy it again...
The cheapest solar panels per KWH are the 250w high voltage ones (public prices around 90$ each) standard size 1.6m x 1m x 40mm. Mounts are all designed for those, so cheaper also. With 100w RV 12V panels you triple the cost par KWH. Even worse with flexible ones that do overheat. Those 35V panels require mppt.
Any thoughts about utilizing 24v or 48v systems? What would the benefits of those on higher draw, what inefficiency would be converting 24 to 12v. Are there efficiency’s to be gained?
Great video, Thank you very much! One question, How many solar panels can you use with this system? Thank you
My roommate bought Kodiak solar generator off of Amazon added solar panels and an additional lithium battery and accomplished the same thing, Prettier to look at as well for those who are feeling lazy.
I would use MC4 for solar panels to the trolley. MC4 exist for 3 different cable gauge. MC4 is good, waterproof, secure, etc. FUSES exist in MC4 waterproof housings to put inline with the panels, panels in series are good to lower cable gauge, smaller 10A fuse, higher voltage means you can have longer cables and get more to your batteries, etc. Good idea to fuse the solar panel line "in situ" in case of thunder, the automotive fuse is not good, a ceramic barrel fuse (in an MC4 housing) might stop the bolt. -in my case is did. An automotive fuse will not. Maybe you could do all the connections on one rail 2x for panels 2x load 2x battery disconnect (disconnects can be fuse holders, or breakers in the right specs ) I prefer fuses : disadvantage : not instantaneous, advantage, if everything melts, the barrel fuse will really cut contact, breakers could be traitors (current in reverse, thinder, etc). You can manually pull the fuse holders, it acts like a swich. Those on a din rail are really neat. There is no battery disconnect on your diagram. Adding solder in the MC4 crimp is a plus.
Hello, what a great video and excel table ! Question : is it compatible with 220v AC (Europe) ? I think it is okay regarding 24V system vs 12V; are there some modifications to make ?
Hi I like your video and information on your solar Generator I am in the process of building it out of my own ignorance could you list all of the wire sizes thanks.
Excellent tutorial. Are there any other reasons for not choosing LIFePo besides exposure to lower ambients, and price dependent decision-making? Do LIFePo control schemes require special charge controllers or unique wiring? Thank you, Tony
Hi very interesting videos about solar power,and i am very very interested on it.
but i have a suggestion for ya rather than run your fuel generators with gasoline,why don't u run your generators with HHO? also u could run your cars with HHO (Hydrogen Generators) which has an almost unlimited generating capacity (also less smelly than gasoline). Obviously even the HHO generator need a lil maintenance,disassemble clean up and reassemble all the stainless steel plates and for fuel demineralized water and potassium hydroxide.
On this way you fixed the problem of gasoline (sure the generator won't run as good as when it runs with gasoline,but you're pretty close for very low cost and maintenance).
lastly i wanna thank you for sharing this very very informative built.which in the near future i will try to adapt for home,and let you know how it goes.
One quick note on your system (actually on your loads):
Instead of a small fridge, consider a small chest freezer. It's much more efficient due to the chest design (cold air doesn't fall out when the lid is open) and the insulation is usually better than that of a fridge. You can convert the freezer into a refrigerator using a device with a drop-in thermostat that switches the freezer's AC power on and off as needed, raising the chest temperature up into the refrigerator range. It's easy to install (plug the module into the wall, plug the freezer into the module and drop the temperature probe into the freezer compartment), is 'fairly' inexpensive ($60?) and requires no rewiring of the freezer. There are several manufacturers out there. This is not an endorsement, but Johnson Controls comes to mind. I'm sure Amazon carries some.
Digging down into a chest refrigerator is not as convenient as opening a door, so there is a convenience factor to consider. But, if efficiency is a major requirement because of long duration power outages and limited backup capacity, then this simple conversion device may be worth looking into.
Nice set of videos by the way.
I just checked Amazon and found some temperature controllers as low as $18. Some are dual purpose working with refrigeration and/or heating equipment. Johnson Controls, Inkbird, Digiten, and KKmoon, plus others.
That’s a very creative solution. In a long-term emergency, your plan could make a real difference to sustainable food storage. Thanks for the idea, and for going the extra mile in locating potential controllers. I’ll bet you’ve started a lot of people thinking. Much appreciated.
Or use freezer to make ice to place in ice chests to use as fridge
Was wondering if it would be prudent to ground the system/battery to an RV frame during long term/overnight use? I know nearby lightning or powerlines can cause a lot of static buildup.
I think you forgot the inverter draws power when online but with no load (understandably), I measured mine at 30W on the dc side. And mine is sold for 91% efficiency (not yet checked) but I put 85% in my calculations. As I plan a 24/7 off grid system without oversight, there will be hours where there are no load but the inverter will not be turned off. So that is 720 WH to add on the loads for one day. 1x idle inverter 30W 24H 720WH in the table.
You need to add a Low Voltage Disconnect, similar to this: mwands.com/store/battery-protection-switch Then you won't inadvertently kill a battery.
A DC bus bar would make the setup nicer, placing most of the stuff in a water resistant cabinet would be a good idea too.
Joe Malovich Thank you. This was my recommendation.
normally the inverter and or solar charge controller does that
An extreme rain day is not zero, the result vary from best 1/4 the power to worst 1/10 the power of a sunny day. The best time to run the generator is at sunset of that rainy day so that you keep whatever benefit from the rainy day solar power generated. The solar controller can extract more or less power from the clouded sun : some MPPT are faster for clouds, others are better at obtaining a better total from rainy day. So the total at sunset is more variable depending on the controller than the full sun total. Around 1 PM I have NEVER seen less than 2KW output from my 8,5 KWC system. Max 6,3 KW on the best sun days. The only way to get zero from the panels in one day is to unplug them.
Hi there, just wondering about the feasibility of connecting this up to charge from a generator until we can arrange a place for the solar panels.
You have done an incredible job that appears highly efficient well planned and executed however ...I am pretty sure there is one very important thing you have missed. . YOU FORGOT TO BUILD ME ONE.
Where did you get the battery discharge monitor.....and is there anything that will automatically shut battery output off if they get to 50%....thanks
Great video.. I Can,t open the links for the wiring. Does this system need some grounding other than the battery itself ?
Your design sounds terrific! Thank you for your rigorous research.
2 questions, which may be due to my lack of understanding of solar generator principles:
1) Does this design allow for both charging the battery from solar panels and discharging them to a refrigerator etc. at the same time? (Some commercial solar generators have this as a big advantage vs. their competition.)
2) How long does it take to recharge the battery when it's low or just about empty? - or is this system designed to keep a high level charge always in place? (Some commercial solar generators take 27 hours to recharge when the battery is completely empty, and some others take 6 hours or less.)
Thanks for your help!
Two good questions.
1) yes, the system is designed to both charge the batteries, and drive the load simultaneously
2) charge time will depend on: the amount of consumed battery power being replenished; the number of sun hours in the day; the size and number of solar panels; and the amount of charging power being diverted to the load while the batteries are charging
Unless you have the most expensive battery type, you can only draw 50% to 80% of the battery’s capacity (depending on the type) without damaging the battery, so you can’t “empty them”, and this also needs to be configured.
Since there’s so many variables, I built all the math into the Design worksheet you can download. (Link in the description. elle the video.). I’m working on a build video for the final version of my generator. Look for the video next week.
Hope this helps...
Thanks very much! Looking forward to your video next week. Best regards.
Great build!! I can't wait until your Rev 3 video. I noticed your diagram is named Rev 3 so video may be coming soon :)
I almost have all the parts for my build. I wanted to know how much 10 gauge wire did you use?
Did you use any other gauge wire? If so, how much of each?
Thanks for the kind feedback. The welding for the rev 4 cart finished today, and the paint is drying. Tomorrow, I get to do the final build, and.that’s going to be fun. There’ll be a final version video, wiring diagram, and likely a more detailed guide video in about a week. There’s very little 10 ga wire - just what’s needed to get from the charge controller through the fuse block to the battery -less than 2 ft. The inverter uses the heaviest wire - 6 ga that came with the inverter. The 12V panel uses 12 ga and 14 ga - about 4 ft. of each gauge in red and black. I’ve added a DROK DC 8-63V LCD Digital Battery Capacity Monitor to the unit ($14 on Amazon), which you will have seen in the Rev 3 diagram. It really helps in evaluating voltage to protect the battery. Use an MPPT controller if you can - it’ll give your system a higher capacity. Good luck with your build...
Someone gave a suggestion in a comment about using a Low voltage Shutdown Relay Switch for this system. They recommended this product:
mwands.com/store/battery-protection-switch
What do you think?
Thanks for the link. A low-voltage relay’s been suggested before, but the particular model was hundreds of dollars, considerably more that he battery it was to protect. You suggestion is much more attuned the the project budget. I’m not sure about the cutoff voltage spec though - I’ll do some homework and respond back...
In Step #2 of your spread sheet, explain where you get the "Minimum inverter wattage" figure...
Great Exposé One other consideration is the Standby power draw, i.e. How many watts the inverter draws when it's on but with no load on it
This particular inverter has a negligible no-load draw - 0.12A @12.8V or under 1.5W. Good call - I hadn’t considered it. Thanks!
Desert Prep Glad I could help, All inverter's have it, Usually the higher the capacity the higher the Standby draw.
But wouldn't you just turn the inverter off if there's nothing plugged in? just saying
Judith Lawrence That’s true for intermittent uses, such running power tools and appliances, But for a Refrigerator the Inverter need to remain on continuously because Refrigerators cycle on and off
Excellent design and documentation! I understand the economics of battery choices, not the best but my pocket book would probably have made the same decision.
1.5 watt standby for the inverter? Is that a measured value or an advertised rating? Seems way low to me, there is usually a big jump from 1kw to 2kw on inverters.
Possible improvements: Mount one end of your panels with a piano hinge and use a notched wooded arm on the other that can be adjusted from below to maximize solar output. 1notch each for winter, summer, then fall/spring.
Upgrade your battery charger to a NOCO GEN2 charger @$150
For a 2kw inverter I would have at least 3 batteries and a low voltage disconnect.
Overall excellent design.....now you have me itching to build one, which means expanding my existing “Deer Camp boondocking” setup.
If this is really a “Prepper” setup your still EMP vulnerable.
I'm looking for a system to give current down in JA. We have a ton of wind but also sun. I'm looking at this one as I'm good with the physical and not the technical.
hi verry good will like to build one need to calculate how many battery to run a refrigerator for 12 hrs iam in puerto rico
Can you provide a wire gauge list for each connection
In the parts list. You have "X2Power Premium AGM BCI Group 27 Car and Truck Battery" in the description. Because this a car battery is there a better battery to use?
Bless fore the no lege
Hello, I have recently purchased the black and decker trickle charger. I attached it to my pop up camper battery and let it charge for 3 days. The outside temp was in the 90s so I decided to see if the trickle charger was getting hot. I found that it was really hot to the touch. Is that normal? I unplugged it to be safe. I had purchased it to make my solar generator.
Does this work on wind turbine generator stator-and magnetic rotor. Coz I’m thinking about it, thanks
I HAVE 1 100W AND 40 W CAN WE MIX THEM AND DO I NEED BOTH POWER CONT OR WILL THE 100 W BE OK
How about adding a super cap to the kit
Hi! Thanks for this excellent work!! However,I could not download the guide. Any help?
Does anyone have an updated link to the design guide worksheet? Thank you.
Why have you still got the PWM wanderer Charge Controller and not a MPPT like you said ?
👍
Could I double the amount of solar panels and/or double the amount of batteries in order to operate a full size refrigerator using the same inverter and MPPT controller?
Isn't there a way for the system to automatically cut of before the battery gets to low.
I don't see protection for the battery? in my case I put a 80A trip switch in which cuts the battery of from the system.
I’ve given some thought to this, and with everything on the battery fused just inches away, I’m not sure there’s much utility in a main battery disconnect. If I build a similar setup in my RV, for instance, I’d definitely have the disconnec6 switch, and a battery isolator as well. Thanks for the suggestion - I’m sure a lot of viewers will be on your side on this. BTW, there’ll be a follow up featuring the complete assembly of rev 4 of this project out next week. You might be interested in the upgrades in the rebuild.
How can I use this on my wan/tiny house??
im trying to print off the diagram but im not finding it ,can you help me pot.
The links no longer work. Are the wiring diagram and design guide still available?
Hey there, I followed the 4th gen instructions and part guide, but the fuse box is entirely different from the one you use in your videos. I wired it up like you show, but it does not work. I took it apart and it seems that one entire side of the fuse box is not for connecting positive power. It also seems like I would need to connect the batteries to the bottom bolt instead of through one of the fuses. Not sure what I'm doing wrong or if I need to buy the identical fuse box you used
You're right. The new fuse block is more sophisticated, and I'll update the wiring diagram to correctly show it. For now, connect the main power wires to the pos/neg studs. Then connect the pos wire and neg wire for each item on opposites sides of the appropriate fuse (be sure of your polarity). The new block has internal busses to provide neg ground for each of the pairs, and fused positive on the other side.
Can you please provide me with circuit diagram and equipment required ........
May I buy on of these unit, please respond at you convenient.
Is there an updated link to the files?
You keep mentioning that "you have to make sure the battery doesn't fully discharge". Exactly how is that done? Once the load is being drawn on the battery........it keeps being drawn until there is no more. Can that be prevented? Can a "battery saver" be installed inline to preserve enough power to save the battery? Or is there something out there?
Regardless, great videos and Thank You for not believing in moats. Godspeed.
I think you can find good solution on Avasva.
have you got an email address that i may be able to email you on?
I know more about diy from Avasva handbooks!
I don't know why but it drives me nuts when people call a solar panel and battery backup a solar generator. At least in this case it's the two together and not just the UPS or power bank, he's calling a generator....
I recently found a website from which you may get coins and gems. It is called Gamecrook.
