I’ve got a fm80 charger controller charging 16x Winston 200ah cells.
It has been running amazingly for almost 2 years with only needing the generator twice.
I got home from work today and the battery was on 50%!
The CC showed CHARGED where is normally says bulk or float and 0amps going to the battery.
It was overcast and about 6:30 pm but I selected restart on the CC and it went into BULK charge and was putting out 10a.
I believe it did this once before in 2 years.
Does anyone know why it would not recharge the battery once it is drained to say 98%?
Thanks
