Work modes Self-use (with PV Power) Self-use (without PV Power) Feed in priority
Force time use
Back up mode

Description Priority: load>battery>grid The energy produced by the PV system is used to optimize self-consumption. The excess energy is used to charge the batteries, then exported to gird. Priority: load>battery When no PV supplied, battery will discharge for local loads firstly, and grid will supply power when the battery capacity is not enough.
Priority: load>grid>battery The power generated will be used to supply the local loads firstly, then export to the public grid. The redundant power will charge the battery.
Priority: battery>load>grid (when charging) Priority: load>battery>grid (when discharging) This mode applies the area that has electricity price between peak and valley. User can use off-peak electricity to charge the battery. The charging and discharging time can be set flexibly, and it also allows to choose whether charge from the grid or not.
Priority: load>battery When the grid is off, system will supply emergency power from PV or battery to supply the home loads (Battery is necessary in EPS mode).

Make sure the load powering rating in within the EPS’s output rating. Or the inverter will shut down with an ‘over load’ warning.When an “over load” is appeared, adjust the load power make sure it is with the range of the EPS output, and turn the inverter on.For the nonlinear load, please pay attention to the inrush power make sure it is within the range of the EPS output.
