I have 4 12v 100ah lifepo4 batteries and 4 250w solar panels. Im trying to determine what charger/inverter i need to do 48v.
if the panels have an open current voltage of 37.6, in series would this give me 150v?
So i would need a controlled that handles over 150v and my 8amps is negligible.
Or would it be better to series- parallel the panels and get 75.2v and roughly 16amps.
Looks like the charge controller usually go by amps 20,30,50 etc. if my panels were in series I would only have 8amps so what size controller do I need?
