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.
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.
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 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.
