User Manual V1.0-2023-10-30
The inverter reserves a dry contact controlling port, which supports connecting additional contactors to
enable/disable the loads, such as household loads, heat pumps, etc.
The load control methods are as follows:
• Time control: set the time to enable/disable the loads, and the loads will be turned on or o
automatically within the setting time period.
• Switch control: when the control mode is ON, the loads will be enabled; when it is OFF, the loads
will be disabled.
• BACK-UP load control: the inverter has an integrated relay controlling port, which can control
the loads o or on. In o-grid mode, the loads connected to the relay port can be turned o if
the overload at BACK-UP is detected or the battery SOC value is lower than the battery o-grid
protection setting.
For more detailed instructions, please refer to the WE Mate User Manual.
