My name is Billy i live on my 200 acre farm in central Ontario with my girlfriend and our GSD and chickens. I am working on my solar system as I can afford it. I have a 300 watt 48vdc panel now, with 4 car batteries and a cheap MIJ charge controller. It seems the charge controller wont work when I connect the battery bank in 48 volts, but will pass voltage when its connected either 12vdc or 24vdc. I had it at 12 vdc for an hour or so, as the sun came up it started to bring the voltage up too high, so i shut it down. connecting it at 24 VDC will pass current too, but just not at 48vdc. am I doing something wrong? or should I just scrap this 80 dollar controller and get something decent?
