I’m going to overpanel my 40a renogy solar controller (12v / 520W) and in theory it should work. My renogy controller is 100vdc and my panels are 535w each. Each panel has approx 50v and 12.5 amps. I will be wiring these panels in parallel using 8 awg wire. 8 awg wire can do 40amp . So these 2 panels in parallel will only be at approximately 25amps at peak times and my solar controller with only be using 50v of my 100vdc. I heard a guy say that the panels don’t push power to the control the controller takes what it needs from the panels. And gave an example like this…..A light in your car uses 20w/ 1amp. You battery doesn’t push its full power to the light. Think of your solar controller as the light . The light will only take what it needs from the battery, as long as you are below the specs on vdc.
Am I wrong, and is this a bad idea?
