Solar Charge Controller
Looking at solar and seeing different options for controllers. What's the difference between PWM and MPPT?

Hi,
If choosing MPPT go for the highest voltage the controller can accept. Get the line losses down to 1%. Use a quality controller.
I have seen 17 amps @13.8 volts when the temperature outside was 39 c (100 f) from 256 watts of panels.
The unisolar panels do 3.88 amps each. I have four for a total of 15.52 amps.
So, at least in my case, MPPT works well for me at high temperatures.
