- I’ve gone ahead and used three 100w solar panels to charge three 100ah Renogy Gel Batteries that run power through a three thousand wt sine wave inverter that runs my eight thousand BTU window AC. I am not a professional or expert in any way, but that's what makes this so awesome, it means anyone can do this!
Items I have Used:
Three 100w Solar Panels (Random)
Three Renogy 12V 100AH - amzn.to/3K8gFMx
One Renogy 60A 12V MPPT Solar Charge - amzn.to/3uT1cK6
3000W Pure Sine Wave Inverter - amzn.to/3u7YBg1
If anyone wants to help support me, shoot me a message! Or if any company wants me to review anything, let me know!
300 watt solar panel isn't charging your battery fast enough to keep up with the draw from the AC, that's why you need 3 batteries.. up your solar panel to 600+ watt and you can run all day with just 1 battery.
Thanks really.I have 6 100watt solar panels and the same window unit. Actually I have more solar panels so I'm on my way
Thank you! This is what people who are trying to save money in Florida need!!!!
I suggest to people that one of the first things that they should get is a plug in energy monitor. Last I checked they were around $20 to $30. I got a couple straight from China for a little less.
With this, they are able to plug it into the wall, then plug an appliance into it, and it will measure the electricity the appliance uses in real-time and also over time.
If you had one of these, you would see that your air conditioner uses approximately 500 Watts while the compressor is running. You would also see how much it uses in a 24 hour period.
With this solid information you would be able to size your system appropriately.
A word of warning though. Once you start using free electricity, and you realize you can now be free from electric bills, you can become addicted quickly where you keep needing more, and more until you are powering your whole house and electric vehicle with it. For this reason, I also tell people to think it through and plan for expansion wherever possible. Also, try to purchase products that you would use on the finished system. For example, instead of buying a couple of 50 W panels that you would only use while your system is growing, buy 200 Watt or more panels which are made for a more full-sized system. You'll still be using the full size panels 30 or more years from now.
Have fun in your journey, and enjoy the addiction!
I Run 4 Renogy 200AH AGM Batteries in 24 Volt Packs with 2 Renogy 60amp MPPT Charge Controllers for each Battery Bank and Running 2 Victron 24/1200 Inverters and 1000 watts of Solar Panels on each System and They run anything I Throw at Them.

Well you seem pretty smart to me. I can wire a house or a car. Your video explained more than most of the SMART guys out there in a simple form people can understand.
thank you for showing us this!! this is amazing!
Cool setup. Wonder if you could get away with less battery if you had a few more panels. Been researching building a setup like this in Florida. Only problem is wife would kill me as well with all those components out in the open! Keep us posted when you build a cabinet.
You need a need a fuse on the battery and the solar in & out. Shorter battery cables would be better and you dont want the pos & negative battery cables coming off the same battery in the parallel chain
What size fuse is recommended
@derekwaltman6 If you have a 100ah battery and plan to draw upwards of 100A - 100A fuse and 2 AWG wire. The fuse for the solar controller will be the max your charge controller is.
With your three batteries wired in parallel you need to move one of the cables supplying the inverter to the third battery. In your present setup you are taking power primarily from just one battery and that is NOT good for the "health" of your battery bank.
Thanks for your video because I have been looking for a setup like this. I'm not ready yet because every time I watch a video it's something different And just like you said its thousands of dollars. I don't have thousands of dollars to spend.
Great video
I'm stuck in a van in FL without AC so I got a 5000 btu window unit and put it in my back window, put 460 watts on the roof with 60 amp mppt, and 200AH LiFePo4 and 1000 watt sine wave inverter... its been working but im about to try it in the florida sun and see if it cools the van while sitting in the sun
I hope you've got yourself unstuck from your van. I hear baby oil removes adhesive well.
Since it's been 2 months, how has your system been working out with the AC unit?
@@johnwyman6126 well i would need more insulation and that's the biggest issue i think. so I never used it much. I got myself an art studio and i been sleepin in here in Asheville. but yeah it's 20 deg cooler here than a lot of other places in the east anyways
Yesterday I ran an Frigidaire 5000 btu for 10 hours with a wetown 1500 and xzny 24v 2560…. It averaged 350 watts and it was hot outside, did an awesome job, boy it was hot yesterday. I did it as a test because my ac just arrived…. Good luck everyone also ac said it was Canadian lol energy rating
Hey @zodaguado6655, I’m trying to do a similar set up like yours in my pickup truck camper. Could you elaborate more on the equipment you used. You’re the first first person I found that is achieving some good results. 10 hours of AC off of solar would be amazing. I live in Florida.
@@oscarcandelaria6287 so it was Solar stored in a wetown 1500, 1280 wh, combined with a xzny 24v lifepo,,, they were both fully charged, the lifepo battery was connected to the wetown power station with an XT-60 to alligator clips…. It charged my power station at 333 watts an hour… as the 5000 btu Frigidaire ran, the power station was getting recharged by the xzny 24v 100 amp battery,,, worked really good and those frigidaires are strong… that was running it max too
Kevin great video stay connected
Thanks! I think I will be creating a follow up video and uploading it in a couple of weeks!
Maybe set the ac on Eco mode and let it run longer or even full time. Something to experiment with. Thanks, great info.
Thank you for all you've shared! Great job! 👍
How many watts solar panel do I need to power a air conditioner that's 500w ?
Thank you. Good job.
This was awesome, thanks for sharing!
A propane Preaditor 5000 will do all that for 16 hours without stopping. And More !!
Sounds like you need more solar panels.
Awesome, good job😎👍
If you are using more electricity in the daytime than at night, you need more panels, not more batteries.
I want to set one of these up. I would be using a 5,000 BTU AC, which is about 500 Watts. And the space is very large, so the compressor likely would not shut off. So a constant 500 Watt load.
I am thinking of getting 4, 250 Watt solar panels, to run the AC during the day while charging the batteries, then using the batteries at night to run the AC all night.
How big/many batteries do you think I need to do that?
From what little research I have done I want to build a 500 watt system for a 5000 btu window ac. Good build with no problems would be, 400-500 watts of solar and about 300Ah worth of battery storage. But that is for a 24volt system... I live in Arizona so that is why i have those numbers. But if you live where it is cloudy and not very sunny.. maybe bump up to 800 watts of solar 400-500Ah battery... But again this is just with what little research I did, I am definitely no expert at this stuff
How many watts solar panel do I need to power a air conditioner that's 500w ?
Thanks! Here it's sunny too. I am in southern California. @@andygarcia8220
Why can't you run your ac at night? Even on low during the night? Are maybe you need 2 more batterys????????
You need a lot more solar…that controller will handle a lot more.
hang on did you say you had your panels wired parallel? - the charge controller was reading 30v - 3.3amps suggesting series wired?? or am I reading it wrong?

What's the cost for all this that's exactly what I need
Usung the set up this year?? San tan solar.... you need some more panels bud
How many watts solar panel do I need to power a air conditioner that's 500w ?
I want to do this, what did it cost you to do it and was it easy? I have zero knowledge when it comes to solar
I just checked the price for his set up. Not including the solar panels or the a/c it's 1353 before tax.
Hey sorry about the late response! I actually made this all for JUST about 1k (USD). I bought some used solar panels and made my own cables which saved me money! The most expensive items out of my set up are my batteries, hands down. I wouldn't say it was easy per say, but I was in the same boat. I had zero knowledge going in, but there is so much out on CZcams and Redditt that you can make it happen! Just remember to be careful since it's electricity!
Dude, liked the vid. I’ve been toying with the idea for running my fridge in case I lose power.
