Connect one end of RJ45 of battery to BMS communication port of inverter. Connect the other end of RJ45
cable to battery communication port.
Lithium Battery Connection (optional)
If choose lithium battery for the inverter, you are allowed to use the lithium battery which has been
configured. There're two connectors on the lithium battery, RJ45 port of BMS and power cable.
Please follow below steps to implement lithium battery connection:
Assemble battery ring terminal based on recommended battery cable and terminal size (same as Lead acid,
see section Lead-acid Battery connection for details) .
Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are
tightened with torque of 2-3Nm. Make sure polarity at both the battery and the inverter/charge is correctly
connected and ring terminals are tightly screwed to the battery terminals.
Connect the end of RJ45 of battery to BMS communication port of inverter.
The other end of RJ45 insert to battery communication port.
Note: if you choose lithium battery, make sure to connect the BMS communication cable between the
battery and the inverter. You need to choose battery type as “lithium battery”
Lithium battery communication and setting
In order to communicate with battery BMS, you should set the battery type to “LI” in Program 5. Then the
LCD will switch to Program 36, which is to set the protocol type. There are several RS485 protocols in the
inverter which can match some customized battery, Please consult with supplier first before you choosing
the battery model.
Connect the end of RJ45 of battery to BMS communication port of inverter
Make sure the lithium battery BMS port connects to the inverter is Pin to Pin, the inverter BMS port and
RS485 port pin assignment shown as below:
