Gents.
The unit is 40kwh storage capacity and can load peak at 10kw @ output voltage 415vac which is phase to phase voltage of a 3 phase output. So 1 phase to neutral is 240vac. ( Australia 50hz ) different in other countries where voltage and Hz are different.
The DC stored in the battery is converted to AC voltage output of 3 phase via the dc/ac converter a sign wave generator which produces the AC wave form like a
Variable Voltage Variable Frequency AC motor speed controller.
Output can be controlled via the inverter.
The battery is just a swimming pool of stored electrons.
