I see people have Error codes but i cant seem to find where you locate them. i have been reading and cant find answers so decided to see if anyone could help or point me in the right direction before i purchase a new MPPT.
I have a 100/50 MPPT it can charge batteries during day but when i check in on it in morning its switched off no LEDS. i have disconnect positive Panel and Battery on MPPT re connect and it will charge batteries all day again. same thing next morning, not sure when it turns off or why. couple weeks prior to this issue i upgraded the solar from 120w panel that looked shattered to the 320w panel, but certain its was working fine and ive only just notice this problem,
System 220AH battery, 320w 12v Solar, MPPT 100/50 controlled by BMV 702
appreciate any help or direction
