Using my batteries wisely?
I have a off-grid PV system with 8, 200ah batteries. I have just been using it as a back-up system in case of grid power loss. The array is producing up to 5kw a day and I want to use it now to power a few small appliances which I will take off the grid, small fridge in garage and my aquarium. Given how the batteries degrade with each cycle, assuming I use 5% of the battery capacity each day, would the small savings off the electric bill offset this loss of life on the batteries? Any other ideas/tips how to use the wasted energy when the system is in float? Thanks.
