Reset
This reset has the functions of manual wake up and start, manual shutdown and sleep, and reset. Users can flexibly use it according to the actual situation. The specific operation methods are as follows:

Manual Wake Up Function: When BMS is in hibernation state, press the button for 35 and release it. BMS will be activated and the battery will return to normal working mode.
Manual Sleep: When the battery is in the normal working state, press the button for 3 seconds and release the button. The battery enters the low-power sleep state.
Reset Function: Press for more than 6s to reset the battery when the battery is in normal working state.

RS232
It can communicate with the upper computer through RS232 interface and monitor various battery information through the upper computer. The default baud rate is 9600bps.

RS232 Port

RS485
RS485 terminal: (R145 port) the RS485 terminal outputs battery information. The default baud rate is 9600bpS. When batteries are deployed in parallel, you need to set the address of each battery using a dip switch.

RJ45 Port

Pin definitions of the RS485 port

RS232
CAN terminal: (RJ45 port) the CAN terminal outputs battery information. The default baud rate is 500K. When batteries are deployed in parallel, you need to set the address of each battery using a dip switch.

ADD Switch

If battery strings are connected in parallel and need to communicate in cascading mode, the hardware address of each battery must be configured. The hardware address can be set using the dip switch on the board,
When the batteries are in parallel, address 1is the host and other addresses are slave. The battery at address 1 is connected to the inverter, If the address is 0, it is in single-battery mode. For details about the switch, see the following table.

Schematic diagram of battery parallel installation

Note: When multiple batteries are connected in parallel, the battery at address 1 communicates with the inverter.

NOTE: The battery should be turned off during installation. After installation, check OK and then turn on the battery.

Installation Tools

Attention before installation
Insulation tools should be used to prevent short circuit during installation.
Power terminal installation must be checked for tightening, whether there is rust, corrosion or other foreign bodies, if there should be wipe Clean, tighten the bolt, the battery bolt virtual connection will lead to the connection voltage drop is too large, even when the current is large
The heat burned the battery.
Following tools are required to install the battery module:

Electric tools

wire cutter

Crimping Modular Plier

NOTE: Use properly insulated tools to prevent accidental electric shock or short circuits. If insulated tools are not available, cover the entire exposed metal surfaces of the available tools, except their tips, with electrical tape.

Installation Steps

When installing batteries, strictly follow the following steps. Do not change the installation sequence at will

Before installing the battery, ensure that the battery is powered off or hibernated, If the battery is turned on or woke up, press the “REST” button on the battery panel. Hold down the button for 3 seconds before releasing it. At this time, the battery will enter the hibernation state, and the battery has no voltage output.
Place the batteries to be installed into the rack one by one, and install the screws that secure the batteries to the rack.
Connect the negative wires: After the battery is fixed, connect all the negative terminals of the battery together, and finally connect the negative terminal of the inverter DC input to the negative terminal of the battery.
Connect the positive wires: Connect all the positive terminals of the battery. Finally, connect the positive terminal of the inverter dc input to the positive terminal of the battery
Connect the parallel communication lines: See the figure below.
Use this cable to connect the communication connection between the batteries.
Connect the communication cable between the battery and the inverter:

Label Name: Remote Box This end connects to the Remote Box of the inverter.

Label Name: RS485 This port connects to the RS485 port of the battery.

Note: This communication line should be connected with attention to the direction.
Setting the Battery Address: After the preceding operations are complete, set the IP address of the battery connected to the inverter to, and set other IP addresses from 2 until all the Settings are complete.
Note: The address of the battery must not be the same. Otherwise, communication will be affected.
Check that all connections are correct and firm.
Start the inverter to charge the battery. In normal state, all the batteries will be activated and enter the working mode.
Note: if the inverter has no battery wake-up function, you can manually press the rest button to wake up the battery.

Trouble Shooting Steps

Preliminary determination steps
The battery can be turned on, but red light is lighting, and cannot charge or discharge. If the red light is lighting, that means syster is abnormal, please check values as following:

Temperature: Above 55°C or under -20°C, the battery could not work.
Solution: to move battery to the normal operating temperature range between -20°C and 55°C.

Current: If current is greater than 110A, battery protection will turn on.
Solution: Check whether current is too large or not, ifit is, to change the settings on power supply side.

High Voltage: If charging voltage above 54V, battery protection will turn on.
Selution: Check whether voltage is too high or nat, ifitis, to change the settings on power supply side.

Low Voltage: When the battery discharges to 44.5V o less, battery protection will turn on,
Solution: Charge the battery for some time, the red light turn off. Excluding the four points above, if the faulty is still cannot be located, turn off power switch of the battery and repair
The battery cannot be charged or discharged

No charging: First check that the charging voltage of the charging device is normal, if the charging voltage is normal (52.5V-54.75V), and then use the upper computer to connect with the battery, read the detailed data of the battery, check whether the voltage and temperature of the single battery are normal, if the charging equipment is normal, the general reason for not charging is: the single charging over voltage protection or high temperature protection

Fail to discharge: Disconnect the battery from the load and measure whether the voltage of
the battery is normal, If the battery has no output voltage, press the Reset button to sleep the battery first and then wake up (restart the battery), and test the battery voltage again.If the battery voltage returns to normal, it indicates that the battery is protected.Check the load,

If there is no voltage output after the battery is restarted, connect the battery to the host computer and check whether the battery voltage and temperature are normal.

Generally cannot discharge the reason is: temperature protection, over current protection, under voltage protection.

Emergency Measures

Leaking Batteries If the battery module leaks electrolyte, avoid contact with the leaking liquid or gas. If one is exposed to the leaked substance, immediately perform the actions described below.
- Evacuate the contaminated area, and seek medical attention.
- If the body comes into contact with harmful substances such as electrolytes, wash it thoroughly with soap and water immediately. I you feel unwell, seek medical attention immediately.
If smoke or open flame is found in the battery, use only a dry powder extinguisher. If possible, the battery should be removed and placed in a safe place before the battery module catches fire to avoid greater damage.
Damaged batteries are dangerous and must be handled with great care. If faulty batteries need to be stored, store them in a special warehouse and take fire control measures.
If the electrolyte of the battery is found to leak, then the battery needs to be scrapped, Contact a professional battery recycling company in your area.
