I put together an emergency solar powered, 12 volt system to play around with solar. This is in preparation for the 15Kwatt grid-tied system that I’m currently putting together. The 12 volt system uses 2-Renogy 200 Watt panels connected in parallel to a 12 volt Solar charge controller, a variety of 12 volt batteries and a Renogy 2000 watt pure sine wave inverter. This puts out 120 vac single phase. The home system in the US generally used 240 vac that is split into 2-120 vac lines that should be evenly divided amongst the house’s outlets. In order to drive your entire house, you need to measure how much current you’re using. If you drive both 120VAC lines with the same 120VAC output from your DC/AC inverter, you have to make sure this is less than the current the inverter is rated at. So for my Renogy inverter rated at 2000 Watts AC, that’s 120 vac at 16.666 Amp. Converting this to DC, we get 12vdc at 166.66 Amps. After being overly confident I ran my Tile Saw with the Inverter and blew the Renogy’s internal fuses even though I had a 250 Amp fuse between the battery and Inverter. I discovered that the Renogy’s 10 - 25 amp automotive blade fuses were soldered to the circuit board. I ordered some fuse holders and 5 new 50 Amp blade fuses to repair and it has worked fine ever since. So do your measurements and calculations and if it didn’t rain so much in Oregon, I would suggest using used solar panels.
