Just to share, I have a small 12 volt system…Xantrex 40 amp pmw controller, 3 Kyosera 135GX-LPU 12 volt pannels (wired in parallel) . On the load side of the CC, I have a high grade manual switch where i can redirect the output current 1) to a small (6 golf cart battery) array; 2) to a modified...
Just Wondering, when you switched from pwm to mppt I’m assuming that you keep your panels wired in parallel….you current mppt pv panel configuration is not in series…right?
I understand that if you want to use LifePo4 batteries, a mppt controller is highly recommended. From what i have read, the pulse charge algorithm of a pwm controller is hard on lithium
