Simple DIY 800 Watt Off Grid Solar Powered Cabin Home Rv setup. so went to help my Neighbor setup a simple 800 Watt Off Grid Solar System for her cabin, she only has 4 led lights in her home 1 led tv and a Refrigerator. she has 6-6v golf cart batteries wired in series and Parallel to make a 12v battery system. 1-2,000 watt inverter, 1 midnite solar charge controller, 5 solar panels each solar panel is 160w I wired them in series to run the solar panels in high voltage. I also installed 3 dc disconnect switches 1 between battery and inverter 1 between battery and charge controller and 1 between solar panels and charge controller. The charge controller steps down the high voltage to charge the batteries Correctly. I will make some adjustments to the charge controller once I find the charging spec for the batteries. so far everything is running good but I will do a follow up. I’m glad I was able to help her.
