•  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 BOA.

• Make sure battery cable placement is installed correctly.

• When the battery is being installed or repaired, make sure the battery is powered off and us ing 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 communication with inverter.

Environment Safety

Dimensions

Capacity Options

The battery can be parallel connected for extending power(kW) and energy(kWh)

• The maximum power(kW) is limited by main cables from master battery to inverter
• The maximum 8 battery packs can be parallel communicated.

For example, ONE PACK is 2.56kWh,

• 2.56kWh

AND MORE ….. .

Working status display light

① Standby :Green light flashing

② Discharge : Green light normally

③ Trouble/alarm: Red light normally on

④ 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.

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.

BATCOM pin interface definition

• Please find communication ports in operation area
• RS232 communication baud rate is 2400
• RS485 communication baud rate is 9600
• Please wire in cables from bottom inlets firstly.

Address switch settings

Multiple Batteries Parallel Connection

• Please set dip address switches as above.
• Please see communication ports link connection below
• Please see power parallel connection below.
• Please ensure that the equipment is connected permanently to the protective ground individually or parallelly.
