Electrical problem I think??
So I thought my rover 20a had gone out, reads day but not processing any power and input like 12.3v 0 amps
after working thru cables etc I find if i unplug solar cables from the rover I can test 70V all over the series, remembering I have a pwm also so I try it before order new rover LI and boom same issue
60+v ( cloudy now) when I plug into the pwm It kills it to 12.3v just like the rover???
3 100a batteries read 12.5v and power the controllers fine
