I plan to install a dual outback Radian system for a residential customer with 20kW of PV power (15.5kW max power). Design calls for using 6 charge controllers, which theoretically could deliver 300 amps combined output to the 660Ah battery bank. Batteries charge rate as designed is maximum 200 amps. Question is, if batteries remain at 100% SOC at float voltage, will there be an issue of passing through 250+ amps through from the charge controllers to the inverter? In theory the battery should not be accepting any amp flow, correct?
If batteries were to be used in a grid down situation and needed the occasional recharge, would the 300 amp available charge rate overload the batteries?
Looking for recommendations on a 48V AGM battery bank that can accept 300 amp charge rate if this setup looks problematic.
