Product description :

How to connect the sensor?
1.Connect the RS485 cable of the AC power acquisition meter to the 485 port of the inverter.
2.Plug the connection terminal of the transmitted current sensor into the port of the collector "CT-IN" (no +-)
3.Connect the AC power supply port "AC-IN" of the collector to the same AC power supply for the load. After the connection, it will light up.
4.In the inverter LCD, enter the "battery grid connection", through the SET {Bat AutoLimit Grid} for Y 4.Connect the inverter to AC power first, then connect the battery, the inverter will automatically output the same power as the power detected by the collector.Therefore, the inverter will not have excess electricity to be sent to the grid (ie: automatic limiter function)
