6.9.2 Connecting the CAN Cable
The CAN cable enables the communication between the inverter and the Li-ion battery from
SUNGROW, BYD and Pylontech.
Procedure
For detailed connection description of the CAN cable, refer to the section "6.7.3 RS485 Con-
nection". Plug the wires into the BMS/CAN terminal according the labels on the bottom of
the inverter.
6.9.3 Connecting the Enable Cable
The Enable cable along with the RS485 cable, are used for communication between the in-
verter and the Li-ion battery from LG Chem.
Procedure
For detailed connection description of the RS485 cable, refer to the section "6.7.3 RS485
Connection".
For detailed connection description of the Enable cable, refer to the section "6.7.3 RS485
Connection". Plug the wires into the Enable terminal according the labels on the bottom of
the inverter.
6.10 DO Connection
The inverter has one DO relay with multiple functions as follows:
• Consumer load control. In this case the DO relay will control a contactor that will open or
close in certain condition. Please choose the appropriate contactor according to the load
power, e.g. the contactor types of the 3TF30 series from SIEMENS (3TF30 01- 0X).
• Earth fault alarm. In this case, the additional equipment required is a light indicator and/
or a buzzer.
Relay Trigger condition Description
Consumer load
control
The load control mode
has been set via the iSo-
larCloud App.
The relay is activated once the conditions
of the control mode are satisfied. See
"8.10.9 Load Control".
Earth fault alarm The earth fault occurs.
Once the inverter receives the earth fault
signal, the relay closes the contact. The
relay remains triggered until the fault is re-
moved. See "8.10.12 Grounding
Detection".
