I have 12 60W panels in parallel. They have a total current of 10.8A for the panels (.9A each). 300Ah 12V battery bank. If i discharge the bank to 50% capacity (150Ah), what other information do I need to figure out how long it would take to fully recharge this bank? I see the specs of the bank have a reserve capacity of 140min 25A, whatever that is. I have a FM-80 MPPT charge controller. Can anyone help?
