Power Limit Function
In discharging mode:
Example1:PV<Load, PV+BAT provide power to Load, BAT provides power to the Grid.
Example2:Load<PV<Load+BAT, PV provides power to Load first, PV+BAT will provide power to the Grid.
Example3:PV>Load+BAT, PV provides power to Load and Grid,and the remaining energy will charge BAT.
The function could be realized by:
(1) Make sure Smart Meter connection and communication well.
(2) Turn on export power limit function and set the max output power to grid on App.
Note: Even if output power limit is set to 0W, there might still be a deviation of a max of 100W
exporting to grid.
Zero Export To Load: Hybrid inverter will provide power to the backup load connected. The hybrid
inverter will also provide power to the home load and sell power to grid by the function of Grid Power
Limit setting.Smart Meter & CT Connection is not needed.
Zero Export To CT: Hybrid inverter will not only provide power to the backup load connected but also
give power to the home load connected. If PV power and battery power is insufficient, it will take grid
energy as supplement. In this mode, a Meter&CT is needed. The installation method of the Meter&CT
please refer to chapter 4.4 Smart Meter & CT Connection.
Grid Power Limit: the maximum power feeds to Grid.
