- Page 52 Mode Type Scenario Brief Description When the load consumption exceeds the Pmax, the inverter will take power from the battery and PV to supply power to the load to compensate for the power that exceeds the Pmax. *To realize the “Peak load Shifting” function, the load power that exceeded Pmax has to be within the inverter max output power, otherwise, the inverter will only output the max power which allowed.
- Page 53 Mode Type Scenario Brief Description Inverter will use power from PV and battery to supply loads in the predetermined period and the insufficient part will be supplied by the grid. In the purely off-grid mode, power from PV will supply the back-up loads first and then charge the battery if there's surplus power.
