SmartSolar MPPT 100/20 no current



Hi all,

My new 100/20 isn’t loading my LiFePo4 battery. Solar voltage is fine and all seems to be correct. I checked the wiring and fuse, etc… I honestly have no idea what the problem could be. :-(

Battery reads 12,7v at battery pins and at the SmartSolar pins, but display shows 11,24V

Probably connections between the mppt and battery. Please check all clean and tight. Also any fuses.
