A solar array that i installed for another person consists of twelve 195w panels connected to a six-string PV Combiner Box, for a 24v system, to a 3000w PowMr solar charger inverter, currently with four 12v 100ah Sealed lead acid batteries (He would like to upgrade to Lithium batteries, to at least double, or triple, the storage capacity). Which is better, 12v batteries at 100 ah, hooked in the same manner my SLA batteries are configured, or would 24 v batteries be better? And if 12 v or 24 v batteries are recommended, which ah rating... 100, 200, 250? and which BMS rating...100, 200, 250? and How many? And connected in what array (series/parallel)?
Also, does the AH rating determine the discharge rate or would that be the watt hours? I want to upgrade to a battery bank that will take more time to discharge. But with that does it mean that it would also take longer to re-charge?
As soon as I think I've got it figured out, I watch another video that doesn't quite answer my question and I get confused all over again.
Not asking much, right?
