5.8.4 Smart Energy Meter Connection
The inverter can provide export control but will require the use of a external smart meter.
The export control functionality has not been tested to AS/NZS 4777.2:2020.
The inverter is equipped with the feed-in power limit function, so as to meet the
requirements of some national standards or grid standards for the output power at the grid
connection point. For the setting of feed-in power limit, refer to the section "7.4.2
Initialization Procedure"
Contact SUNGROW to ensure that the Smart Energy Meter model is available
locally.
This section mainly describes the cable connections on the inverter side. Refer to
the quick guide delivered with the Smart Energy Meter for the connections on the
meter side.
Procedure
For detailed connection description of the Smart Energy Meter cable, refer to the section
"5.8.3 RS485 Connection". Plug the wires into the Meter terminal according the labels on
the bottom of the inverter.
The energy meter is mainly used to detect the direction and magnitude of the
current. And the energy meter data may not be used for billing purposes.

.
The connection procedure of the dry contact is the same as that of the RS485
terminal block.
5.8.5.1 Dry Contact Function
Connection method of the dry contacts is similar to that of the RS485 terminal block.
The configuration circuit board is provided with fault output dry contact and emergency stop
dry contact, as shown in the figure below.
