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.
NO TE
● 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.
