The inverter can work with a smart sensor to achieve Export Power Management function.
NOTE:
Inverters are classified as "Meter Model" and "CT Model" due to hardware
difference.
Meter Model can only connect a smart meter.
CT Model can only connect a smart sensor.
Please consult Solis Sales Rep before placing the order.
NOTE:
To achieve Export Power Management function, the smart sensor
must be installed on the grid side.
Below is the connection diagram of the smart sensor.
Detailed settings please refer to Section 6.5.12.

4.3.9 Logic interface connection
Please follow below steps to assemble RJ45 connector.
1. Insert the network cable into the communication connection terminal of RJ45.
3. Connect RJ45 to DRM (l ) . ogic interface
2. Use the network wire stripper to strip the insulation layer of the communication cable.
According to the standard line sequence of figure 4.29 connect the wire to the plug of
RJ45, and then use a network cable crimping tool to make it tight.
After wire connection, please refer chapter 6.5.9.1 to enable the logic interface functi
on.
Logic interface is required by some local regulations that can be operated by a simple switch
or contactor(Not available in South Africa).
When the switch is closed the inverter can operated normally. When the switch is opened,
the inverter will reduce it’s output power to zero within 5s.
Pin5 and Pin6
of RJ45 terminal is used for the logic interface connection.
