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 1 is 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

2. Installation Tools
Attention before installation:
2.1 Insulation tools should be used to prevent short circuit during installation.
2.2 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
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.
When installing batteries, strictly follow the following steps. Do not change the installation sequence at will:
3.1 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.

3.2 Place the batteries to be installed into the rack one by one, and install the screws that secure the batteries to the
rack.
3.3 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.
3.4 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.
3.5 Connect the parallel communication lines: See the figure below.
Use this cable to connect the
communication connection
between the batteries

3.7 Setting the Battery Address: After the preceding operations are complete, set the IP address of the battery
connected to the inverter to 1, 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.
3.8 Check that all connections are correct and firm.
3.9 Start the inverter to charge the battery. In normal state, all the batteries will be activated and enter the working
mode.
4.1 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 system is abnormal, please check values as following:
Temperature: Above 55ºC or under -20ºC, the battery could not work.
Solution: to move battery to the normal operating temperature range between -20ºC and 55ºC.
Current: If current is greater than 110A, battery protection will turn on.
Solution: Check whether current is too large or not, if it is, to change the settings on power supply side.
High Voltage: If charging voltage above 54V, battery protection will turn on.
Solution: Check whether voltage is too high or not, if it is, to change the settings on power supply side.
Low Voltage: When the battery discharges to 44.5V or 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.
4.2 The battery cannot be charged or discharged.
4.2.1 No charging: First check that the charging voltage of the charging device is normal, if the charging voltage is
normal (52.5V-54.75)V), 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.
4.2.2 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.
5.1 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. If you feel unwell, seek medical attention immediately.
5.2 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.
5.3 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.
5.4 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.
