Modes:

There are three operation modes:
     -    Grid-tie with backup.
     -    Grid-Tie.
     -    Off-Grid.

Grid-tie with backup:

PV power can feed-in back to grid, provide power to the load and charge battery. There are four options available in this mode: Grid-tie with backup I, II,III and IV. In this mode, users can configure PV power supply priority, charging source priority and load supply source priority. However, when Grid-tie with backup IV option is selected in PV energy supply priority, the inverter is only operated between two working logics based on defined peak time and off-peak time of electricity. Only peak time and off-peak time of electricity are able to set up for optimized electricity usage.

Grid-Tie:

PV power only can feed-in back to grid.

Off-Grid:

PV power only provides power to the load and charge battery. No feed-in back to grid is allowed.
