Homemade Solar Cart

Postby Flightnurse1 » Mon Oct 02, 2017 6:45 am

I came up with this idea after a friend gave me two B/P 40watt solar panel and a 800 watt AC converter. I wanted to build something portable so I decided to build it on a wagon. I managed to score 14 batteries (12 volt Lithium 12amp/hr) from the GE guy who came to the hospital to change the batteries in our x-ray room. The 20amp controller has usb ports for charging devices, and the whole thing took about seven hours to build. Works great for a small, portable, solar wagon!

Hmmm...That's impressive.

How many amp hours?

I'm wondering with 6v batteries and an inverter what that might be capable of.......???


A setup like that would be great in the back of my truck for RV camping instead of converting my storage for extra battery storage and access to the sun when the RV is shaded..... :-)


Thanks for the idea....
In honor of RebNavy...RIP buddy. You made me smile. :)

I am figuring the amp hours out. So each battery is 12amp/hr and I have 12 batteries in the cart. Now that it is built, I plan to slowly change the batteries to deep cycle marine batteries, but for now it's great. If I had to do it from scratch, I would probably use the started kit from Harbor Freight for 189 and by the batteries. I love that it is portable and I don't have to worry about protecting it at night.

If you're considering deep cycle marine batteries, check out wal-mart, that's were I got one of my battery banks from (4 batteries).

Everstart, Group 27DC, 80amp/hrs each, $90.00 each. Mine were bought in 2012 and still going strong.
