I recently purchased an off grid home, all was well till the shorter days , I find myself running the backup generator 2 hours a night to keep my battery bank ( 8 x 100ah gell) up above 12.4 v.
The only thing running on the batteries is water pump and our lights.
We pee outside to minimize flushing and turn on one 8 watt led for a few hours at night.
I have 4 x 100 watt shell energy panels (sm 100 12p) with a 2.8 kw magnum inv/charger. I find it hard to understand why 8 batteries can't keep a charge with only one light on and everything else is unplugged.
We use very little power( no appliances, toasted, hairdryer, absolutely nothing)
Do the batteries need replacing?
Can I replace with 2/350 amp hour vs 8x 100 am/h?
Please help
