Page 8: Lithium Battery Connection
Lithium Battery Connection If choosing lithium battery for SPF 3500 ES /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. - Page 9 LCD setting To connect battery BMS, need to set the battery type as “LI” in Program 05. After set “LI” in Program 05, it will switch to Program 36 to choose communication protocol. You can choose RS485 communication protocol which is from L01 to L50, and you can also choose CAN communication protocol which is from L51 to L99.
- Page 10 Default 20%, 5%~50% Settable Note: Any questions about communicating with BMS, please consult with Growatt. Communicating with battery BMS in parallel system If need to use communicate with BMS in a parallel system, you should make sure to connect the BMS communication cable between the battery and one inverter of the parallel system.

Page 24: Parallel Installation Guide
Parallel Installation Guide Introduction This inverter can be used in parallel with two different operation modes. 1. Parallel operation in single phase with up to 6 units. 2. Maximum 6 units work together to support 3-phase equipment. Four units support one phase maximum. Note: If the package includes share current cable and parallel cable, the inverter is default supported parallel operation. - Page 25 Step 3: Remove two screws as below chart and remove 2-pin and 14-pin cables. Take out the board under the communication boards. Step 4: Remove two screws as below chart to take out cover of parallel communication. Step 5: Install new parallel board with 2 screws tightly. Step 6: Re-connect 2-pin and 14-pin to original position of parallel board, and re-connect 2-pin and 6-pin to original position of communication board.

Page 37: Battery Equalization
Battery Equalization Equalization function is added into charge controller. It reverses the buildup of negative chemical effects like stratification, a condition where acid concentration is greater at the bottom of the battery than at the top. Equalizationalso helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this condition, called sulfation, will reduce the overall capacity of the battery. -
