Electrical Safety
Before installation, ensure that the equipment is intact. Otherwise, electric
shocks or fire may occur.
Do not connect or disconnect power cables when battery is power-on.
Which may cause electric arcs and sparks more overfire or personal injury.
Before connecting a power cable, check the positive or negative connectors are
correct.
Do not parallel connection with different batteries.
Do not connect battery with AC directly.
Do not connect battery with PV wiring directly.
Do not connect batteries in series.
Do not connect battery to faulty or unqualified inverter or charger.
Do not create short circuits with the external connection.
Make sure the grid is cut off and the battery is powered off before
maintenance.
Make sure the earth cable is connected correctly before operation.
Recharge battery in every six months.
Recharge battery within 10 days after battery is fully discharged.
Please engage greater than or equal to two batteries when maximum
charge current is more than 80A.
Make sure battery cable placement is installed correctly.
When the battery is being installed or repaired, make sure the battery is
powered off and using a multimeter to make sure there is no voltage in the positive
and negative terminals.
Please use dedicated insulated tools for install and maintenance.
Please make sure all batteries are power-off when multiple parallel connection.
Please check lights on sequence when battery power-on.
Please make sure communication connection connect correctly with battery
and inverter.
Please make sure ADDS dip switch settings are correctly for single or multiple
batteries.
Please check inverter alarm or SOC reading when there is BMS
communicated with inverter.

1.4 Environment Safety
Ensure that the equipment is installed in a dry and well-ventilated
environment.
The installation position must be away from direct sunlight and rain.
The installation position must be far away from fire sources.
The installation position must be far away from water sources such as taps,
sewer pipes, and sprinklers to prevent water seepage.
The bracket must be installed solidly and horizontally.
Do not expose the equipment to flammable or explosive gas or smoke.
Do not perform any operation on the equipment in such environments.
The operation and service life of the battery depends on the operating
temperature. Operate the battery at a temperature equal to or better than the
ambient temperature. The recommended operating temperature range is from 0°C
to 30°C.
1.5 Transportation Safety
The products passed certification UN38.3.
The products have MSDS.
The products belong to class 9 dangerous goods.
Please protect the packing case from the below situations.
Being dampened by rains, snows, or falling into water.
Falling or mechanical impact.

2.5 Working status display light
Standby :Green light flashing Discharge : Green light normally on
Trouble/alarm：Red light normally on Charging: Blue light normally on
Alarm
When the red light is on, some parameters of the battery have reached the warning
value, or the battery has begun to be protected, BMS will send a warning when the
battery is being charged or discharged.But after the battery protection, some
functions of the battery can not be used.
2.6 Operation
Power Switch ON/OFF
To power on the whole battery system, no power output.
Power Connector
There are two sets of power connectors in the operation area, as shown in the
figure, the one on the left is the positive pole, and the one on the right is the
negative pole. The polarity of the power connectors in the same group is the same,
and the battery can be connected in parallel or the inverter can be connected.
Please remove operation plate to find operation area.
Please wire in cables from bottom inlets firstly.

Please use standard M6 lug to install cable and connectors.
Communication Port
There are three RJ45 ports for BMS to inverter and parallel batteries communication.
INVCOM is for updating battery information to compatible inverter or top tier when
necessary. It is RS232 communication. BATCOM is RS485 for link to next battery
pack to allow parallel batteries to work as one group.
INVCOM
The BMS has the RS232 communication function for battery pack data upload, and
the baud rate is 2400bps. RS232 upload communication interface. It can
communicate with the host computer through the RS232 communication interface.
INVCOM pin interface definition
BATCOM
The BMS has RS485 communication for battery pack collection, and the baud rate
is 9600bps. RS485 communication interface adopts 8P8C network cable interface.
