Hybrid Solar Inverter Connect Lithium Battery
If choosing lithium battery for the inverter, you are allowed to use the lithium battery only which we have configured. There’re two connectors on the lithium battery, RS485 port of BMS and power cable.
Please follow below steps to implement lithium battery connection:
- Assemble battery terminal based on recommended battery cable and terminal size.
- Connect the end of RS485 port of battery to BMS(RS485) communication port of inverter.
Lithium battery communication and setting
if choosing lithium battery, make sure to connect the BMS communication cable between the battery and the inverter. This communication cable delivers information and signal between lithium battery and the inverter.
This information is listed below:
- Re-configure charging voltage, charging current and battery discharge cut-off voltage according to the lithium battery parameters.
- Have the inverter start or stop charging according to the status of lithium battery.
Connect the end of RS485 of battery to RS485 communication port of inverter
Make sure the lithium battery RS485 port connects to the inverter is Pin to Pin, the communication cable is inside of package and the inverter RS485 port pin assignment shown as below:
| PIN Number | RS485 Port |
