-- Monitoring software for real time status display and control

Working Principle

• Grid-tied with backup mode: The extra electricity will be transfered to the grid system after the batteries are full charged.
• 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.
• Inverting mode:When grid power is abnormalor disconnected, the batteries will supply pure sine wave power to the loads through inverting circuit.
• PV charging mode: Connecting the PV panels, the built-in MPPT solar charge controller change the batteries.
