Protocol Setting Selection/Communicating directly with inverters

Required Operating configuration

Only the Master Battery (Address 1) needs to be set to the Inverter protocol, all other batteries must have

unique addresses starting at address 2 and ascending in chronological order.

You must connect either the RS485 or the CAN port of the Master battery to your inverter's BMS

communication port.

Protocol Change/Selection Procedure

1. Power off all battery DC breakers (while leaving the power button on), and ensure that

the voltage between + and - Busbars is 0V.

2. The Inverter protocol can only be changed with the Master battery temporarily set to

address 16 (dial all down). After the dial is changed, restart the battery (with only the

power button) for the settings to take effect.

3. On the master battery, Press and hold Enter for 5 seconds to enter the Protocol setting.

4. Select the corresponding RS485 program or CAN program, and press Enter.

5. Press the Return key to return to the main interface.

6. Change address dip switches back to address 1 (Switch 1,2,3 down and Switch 4 up )

7. Power the master pack on again, and the battery will correspond to the program.
