Fluctuating amps during battery charging
For 30 amp input AC current charge setting this would be 3600 watts input. At that power level the inverter is about 87% efficient so the output power would be about 3130 watts. If battery is at 24.3 vdc then charge current would be 3130w/24.3v = 129 amps. When battery gets to 27.0 vdc then charge current would be 116 amps.
