View Full Version : Charge controller

Is anyone using a PWN charge controller with 12 volt batteries and higher voltage solar panels? I was going to use the tristar TR 45 PWM controller with 24 volt solar panels but I was told that I would be loosing 50% of the power the panels were generating. Actually I want to hook 2 24 volt panels up in series so I would have 48 volts. I would have 2 banks of 2 panels each with 272 watts in each bank, that way I could use smaller wire from the roof to the controller because of the higher voltage. According to the voltage calculator I am using I could use #10 wire from the roof. This would be more user friendly and I can get it with the matching connectors that my solar panels have.
