My 100|20 MPPT used to work great. But now it's not charging the batteries.
- lifpo4 battery bank 12v
- polarity is correct check with multimeter
- The battery voltage shown here is 14.19v. When I measure at the charger (bat) it's 13.19v.
Anyone know what to do?
Have you checked the fuse in the bottom of the mppt?
Any other fuses/breakers between the mppt and battery?
Has the BMS turned off charging for whatever reason?
What happens when you hook up a wall charger? Will the battery take current?
