I'm building a system that will have PV for disasters, and an AC charger to
quickly replenish the batteries after a blackout.
What is the convention for sizing these chargers for use with golf cart
batteries?
A charger spec for a 2 or 3 state charger gives the maximum "bulk" charge
rate.
I can choose

between a 15, 30, or 45 amp charger.
However, the 15 and 30 can charge a battery while still drawing current from
the inverter, functioning as a UPS.
The 45 cannot, because the charging algorithm can't sense state of charge
under those circumstances.
The batteries will be the standard 220 ah 6v, series-paralleled into one 660
ah 12V bank.
