3.2 Work Modes

There are three basic work modes that end users can choose through inverter APP.

- Self Use:

The energy generated by the solar panels will be used in the following order: supply to the home loads; charge the battery and then, feed into the grid. When the PV power is not available, the load will be supported by battery to enhance self-consumption. If the power supply from the batteries is not sufficient, the grid will support the load demand.

- Back up:

Under this mode, the battery is only used as a backup power supply when the grid fails, as long as the grid works, the batteries won't be used to power the loads. The battery will get charged with the power generated by the PV system or from the grid.

- Peak Saving:

This mode is designed for time-use mode customer. The customer is able to set up the charging/discharging time & power via APP.
