Networking with Third-party Inverters

Only a SUN2000-(2KTL-6KTL)-L1 inverter or a SUN2000-(3KTL-10KTL)-M1 inverter can be connected to a third-party inverter.
- SUN2000-(2KTL-6KTL)-L1 (V200R001C00SPC117 or later)
- SUN2000-(3KTL-10KTL)-M1 (V100R001C00SPC140 or later)

After the Smart Dongle is updated to SDongle V100R001C00SPC126, meter 2 can be connected.
A WLAN-FE Smart Dongle is required for SUN2000-(2KTL-6KTL)-L1 or SUN2000-(3KTL-10KTL)-M1.
Power meters are required for SUN2000-(2KTL-6KTL)-L1 or SUN2000-(3KTL-10KTL)-M1 to control battery charge and discharge. The system does not restrict the output of third-party inverters.
Meter 2 measures the AC output of a third-party inverter and is not involved in power control at the grid-connection point. When a third-party inverter is connected to meter 2 and the quick deployment is complete, add meter 2 through the Smart Dongle by referring to Adding a Power Meter Through Smart Dongle in 6.3.1.
When charging from grid is enabled on a third-party inverter, it can supply power to loads and charge batteries through the Huawei inverter. In this case, the batteries can work in maximum self-consumption and TOU modes.
If a Smart Dongle is replaced, add meter 2 through the Smart Dongle after quick deployment.
If meter 2 is disconnected, the PV output power and load power displayed on the network management system and app will be abnormal.
The energy flow diagram on the network management system displays the total energy flow of the system, but not the energy flow of a single inverter.
The energy flow diagram on the network management system does not support the display of third-party inverters and their corresponding power meters.

Figure 4-17 Networking with third-party inverters

The RS485A and RS485B on meter 1 are connected to the RS485A2 and RS485B2 of the COM port on the inverter, respectively. The RS485A and RS485B on meter 2 are connected to the RS485A1 and RS485B1 of the COM port on the inverter, respectively.

The communications cable of meter 2 (used to measure third-party inverter output) is connected to the RS485-1 port on the Huawei inverter. RS485-2 port is used only to connect the LUNA2000 and meter 1 (used for battery control)
When meter 2 is connected, only one Huawei inverter can be connected to the third-party inverter. In this case, multiple Huawei inverters cannot be cascaded through the RS485-1 port.

If a third-party inverter is connected to a meter, add the meter through the Smart Dongle after quick deployment.

Log in to the FusionSolar app as installer, choose Me > Device commissioning , and connect to the Wi-Fi of the Smart Dongle. (The Smart Dongle Wi-Fi can be found within three minutes after the Smart Dongle is powered on. If it has been powered on for more than three minutes, reconnect the Smart Dongle.)
