If choosing lithium battery for SPF 5000 ES, you are allowed to use the lithium battery only which we have 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:
1. Assemble battery ring terminal based on recommended battery cable and terminal size (same as Lead acid, see
section Lead-acid Battery connection for details) .
2. 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.
3. Connect the end of RJ45 of battery to BMS communication port(RS485 or CAN) of inverter.
4. The other end of RJ45 insert to battery communication port(RS485 or CAN).
Note: if choosing 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 protocols in the inverter. Please get instruction from Growatt to choose which protocol to match the BMS.
1. 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 pin assignment shown as below:

Communicating with battery BMS in parallel system
If need to use communicate with BMS in a parallel system, an external RS485/CAN HUB is needed to converge the communication cables from the parallel inverters to lithium battery.
RS485/CAN Hub:
Two inverters in parallel:
Six inverters in parallel:
Note: if inverters parallel as 3 phase system, only need to connect L1-Phase inverters with lithium battery RJ45 port to
communicate with BMS. When inverters on L1-Phase are more than 2 units, it would need an extra RS485/CAN HUB to converge inverters on L1-Phase to connect with battery RJ45 port to communicate with BMS.
Note: the above diagrams described the parallel system communicate with lithium battery in CAN communication type,
and it is the same to the RS485 communication type.
