* <mark style="color:blue;">Only third-party inverters that not support off-grid functionality are allowed to connect.</mark>
* <mark style="color:blue;">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.</mark>
* <mark style="color:blue;">On the "Device" screen, set related parameters based on the third-party inverter. Then, you can check detailed settings on the "Device" screen.</mark>

### Method 2: **Connecting using an electric meter**

<mark style="color:blue;">Before connecting to a third-party inverter, make sure that:</mark>

* <mark style="color:blue;">The third-party inverter is properly connected to an electric meter which is purchased from our company.</mark>
* <mark style="color:blue;">The electric meter is properly connected to the COM port of our inverter. For connection ports, please refer to the respective Installation Guide.</mark>
* <mark style="color:blue;">A single or multiple third-party inverters can be selected. Please choose based on your actual situation.</mark>
* <mark style="color:blue;">If an RGM meter is used, the corresponding device serial number (SN) must be selected according to the actual wiring configuration.</mark>

* <mark style="color:blue;">The diagram displays the connections among different cables of equipment. The specific ports shall be determined by actual equipment.</mark>
* <mark style="color:blue;">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.</mark>
* <mark style="color:blue;">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.</mark>
* <mark style="color:blue;">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.</mark>
