EcoRenovator - View Single Post - What is the Best Volts/Amps arrangement for Solar Panel Output to Controller

The losses due to heating up the wire increase with current.
Watts of loss= Current Squared x Resistance.

(Notice that voltage isn't in the formula).

I've never even looked at using a 4 panel series array to charge at 12V..
But, it seems like it would put more demands on the charge controller.
Even with PWM, controlling how hard you hit a 12V battery when starting off with 100vdc, isn't real simple. Something to research there..

In addition to (12, 24, 48 volts) battery packs, I believe my CC can be configured for Golf Karts.. 36volts! LOL!!
