Two 48V EG4-LL batteries will give 5.120 x 2 = 10.24kWh and 200 Ah, if I have a inverter like EG4 6K Off-Grid Split Phase Inverter | 6000EX-48HVconnected to the battery and if I draw 2.4kWh (10A) from the Inverter @ 240V, will the battery last for 200A of battery/10A draw = 20 hrs. or 10.24kWh / 2.4kWh = 4.26 hrs. May be I am totally wrong, please guide me.
