#1 too much battery...wrong
The correct answer 'Not enough solar for the amount of power used'
Cut down on power use
17v is the imp for most 100w panels , the peak voltage is 21>23v
Batteries don't charge at 12v , they charge at 13.6 > 14.4
300w of solar per 100 amp Hrs of batteries is ideal aka The off grid ranch house
It doesn't work that way for RVs
By that comparison I should have almost 2100w of solar on the roof
Or limit myself to 200 amp Hrs of batteries
