Third-party inverter

Method 1: Connecting using Gateway

• Only third-party inverters that not support off-grid functionality are allowed to connect.

• Before connecting to a third-party inverter, ensure that the third-party inverter is connected to the smart load circuit breaker of the Gateway. For connection details, refer to the Installation Guide of the respective product.

• On the "Device" screen, set related parameters based on the third-party inverter. Then, you can check detailed settings on the "Device" screen.

Method 2: Connecting using an electric meter

Before connecting to a third-party inverter, make sure that:

• The third-party inverter is properly connected to an electric meter which is purchased from our company.

• The electric meter is properly connected to the COM port of our inverter. For connection ports, please refer to the respective Installation Guide.

• The diagram displays the connections among different cables of equipment. The specific ports shall be determined by actual equipment.

• On the "Device" screen, set related parameters based on the third-party inverter and the connected meter. Then, you can check detailed settings on the "Device" screen.

• In the off grid state, when the operating power of the third-party inverter is ≤ (load usage power + Sigen inverter charging power), the third-party inverter can operate normally.

• In the off grid state, when the operating power of the third-party inverter is greater than (load usage power + Sigen inverter charging power), the third-party inverter will stop running.
