6.2.4 TEMPERATURE INFORMATION
6.3 COMMUNICATION PROTOCOL SELECTION
6.3.1 PROTOCOL CHANGE/SELECTION PROCEDURE
1. Power off all battery DC breakers and BMS power buttons.
Ensure that the voltage between positive and negative
busbars is 0V.
2. The inverter protocol can only be changed with the host
battery temporarily set to address 16 (all dials down). After
the dial is changed, restart the battery (with only the BMS
power button) for the settings to take effect. (See image on
right.)
3. On the host battery, press and hold the “Return” key for 5 seconds to
enter the “Protocol Setting.”
4. Select the corresponding RS485 program or CAN
program, and press Enter.
Press "Enter" on the Cell
Voltage page to view the
temperature information of
the PCB and the cells
(Shown in °C)
Note: There are only 2
temperature sensors
distributed evenly among
the 4 packs.
IMPORTANT:
Only the host 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 the CAN/RS485 port of the host battery to your inverter’s (or
communication device’s) BMS communication port.
