Reset
Switches the battery management system (BMS) ON and OFF. The
BMS needs to be turned on initially. Please refer to Table 3 for the LED
indicator definitions.
•Switching ON: This is done with a short press and release of the
switch, after which the green RUN LED will start to flicker green.
•Switching OFF: Pressing and holding the switch for 3 seconds will
switch the BMS off. The SOC LEDs will switch off sequentially and
the RUN light will switch off.

RS485 port
There are 2x RJ45 MODBUS (RS485) ports on the battery. Use the
MODBUS port to connect the BMS of the battery to a parallel battery.
Some inverters also use MODBUS to interface with the battery. Please
refer to Table 4 for the pin assignment.
10
CANBUS port
The RJ45 CANBUS port provides communication between the inverter
and the BMS of the battery.
11
Address
Used to set the battery address when the batteries are used in parallel.
•The DIP switches need to be in the OFF position when using a
single battery.
•The DIP switches need to be setup to a unique address when being
used in parallel. Please refer to 5.4 for further detail.
12-13
RUN / ALM lights
Please refer to Table 3 for a detailed overview for these indication lights.
•RUN (green):
•ALARM (red)
