Working Principle
1.Grid power mode: When the grid power supply is normal, the load will be supported by grid power from by-pass, which will charge the batteries at the same time.
2.Inverting mode:When grid power is abnormalor disconnected, the batteries will drive the mains transformer to supply pure sine wave power to the loads through inverting circuit.
3.PV charging mode: Connecting the PV panels, the built-in MPPT solar charge controller change the batteries.
