2. Introduction
R2428 lithium iron phosphate battery is one of new energy storage products developed and
produced under TAB’s quality requirements, it can be used to support reliable power for var-
ious types of equipment and systems. R2428 is especially suitable for application scene of
high power, limited installation space, restricted load-bearing and long cycle life.
R2428 has built-in BMS battery management system, which can manage and monitor cells
information including voltage, current and temperature, further provide protection base on
above information. The BMS can also balance cells during charging to extend cycle life.
Multiple batteries can connect in parallel to expand capacity and power in parallel for larger
capacity and longer power supporting duration requirements.

◊Cathode material is made from LiFePO4 with safety performance and long cycle life;
◊Battery management system BMS)has protection functions including over-dis-
charge, over-charge, over-current and high/low temperature;
◊The system can automatically manage charge and discharge state and balance cur-
rent and voltage of each cell;
◊Flexible conguration, multiple battery modules can be in parallel for expanding ca-
pacity and power
◊Adopted self-cooling mode rapidly reduced system entire noise;
◊The module has less self-discharge, up to 6 months without charging it on shelf, no
memory effect, excellent performance of shallow charge and discharge;
◊Working temperature range is from -10°C to 55°C, (Charging 0~55°C; discharging
-10~55°C) with excellent discharge performance and cycle life;
◊Small size and light weight, standard of 19-inch embedded designed module is com-
fortable for installation and maintenance.

4. Installation
4.1 Package Items
Unpacking and check the Packing List
1) For battery module package:
Two power cables and one communication cable for each battery package:
Grounding cable:
Grounding cables use 10AWG yellow-green cables.
R2428_Operating_Manual_13.05.2021.indd 14R2428_Operating_Manual_13.05.2021.indd 14 17.5.2021 11:35:4717.5.2021 11:35:47
R2428 modules’ grounding is based on metal directly touch
between the module’s surface (SGCC) and rack’s surface.
If uses normal rack, may need to remove the paint at the
corresponding place.
Or install a grounding cable to the grounding point
of the modules.
2) For battery system connects to inverter:
Two long power cables (max. current capacity 120A) and one communication cable for
each energy storage system:
NOTE
These three long cables are NOT in battery package, they are in another extra small cable
box.
If there is anything missed, please contact dealer.

4.2 Installation Location
Make sure that the installation location meets the following conditions:
• An indoor environment
• The area is completely waterproof.
• The oor is at and level.
• There are no ammable or explosive materials.
• The ambient temperature is within the range from 0°C to 50°C.
• he temperature and humidity are maintained at a constant level.
• There is minimal dust and dirt in the area.
CAUTION
If the ambient temperature is out of the operating range, the battery pack stops operating
to protect itself. The optimal temperature range for the battery pack to operate is 0°C to
50°C. Frequent exposure to harsh temperature may deteriorate the performance and life of
the battery pack.

Installation
A. Put battery modules into the cabinet and connect the cables:
(1) Put the battery into the cabinet, follow below picture;
(2) Fix each module with the cabinet with 4 screws;
(3) Connect the cables between battery modules, including grounding cables, follow
below picture.
R2428_Operating_Manual_13.05.2021.indd 17R2428_Operating_Manual_13.05.2021.indd 17 17.5.2021 11:35:4817.5.2021 11:35:48
(4) Connect the cables to inverter.
The power cables’ current capacity is 120Amps(peak).
If the battery system is supposed to congure with an inverter/charger
≥100Amps/2.5kW, must congure multiple pairs of external power cables following the
inverter/charger size.
Power Cable connection:
• For 1 pair of external power cable, connect as A + D or B + C, donot connect as A+B or
C+D to avoid unbalancing current transmitted.
• For 2 pairs of external power cable, connect as A + D and B + C.
• For more than 2 pairs of external cable, need split the battery module into another string
to further handle the connection.
(5) There shall be a manual disconnecting device (breaker, etc.) between battery system
and inverter.

B. Power On
Double check all the power cable and communication cable, check the
ADD switch.
(1) Switch the breaker between battery system and inverter.
(2) turn all the power switch ON.
(3) The one connects communication cable to inverter is the Master Battery Module,
others are slaves (1 master battery congure with maximum 19 slave batteries).
(4) Press the Start Button (SW) of master battery to power on, all the battery LED light
will be on after master battery starts.
If all the battery LED lights on, and then off, which means the battery system is good and
working.

5. Trouble Shooting Steps
Please check the ‘LED Indicators Instructions’ table for the detailed faulty denition be-
fore any trouble-shooting steps.
5.1 Problem determination
1. Whether the battery can be turned on or not;
2. If battery is turned on, check the red and yellow light is off, ashing or lighting, follow
the ‘LED Indicators Instructions’;
3. If the red and yellow light is off, further check whether the battery can be charged/dis-
charged.
5.2 Preliminary determination steps.
1. Battery cannot turn on, switch on the lights are all no lighting or ashing.
Solution: Turn power switch ON, and then charge the battery with external power supply
voltage 26V or more, if the battery still unable to turn on, turn the power switch off and
contact the installer.
2. The battery can be turned on but cannot charge or discharge. If the red/yellow light is
lighting, that means system is abnormal, please follow the ‘LED Indicators Instructions’
to check:
a. Over/Low temperature: Above 55°°C or under -10°C, the battery could not work.
Solution: turn off the battery module, move battery to the normal operating tem-
perature range between -10°C and 55°C.
b. Over Current: If current is > 100A, battery protection will turn on.
Solution: Check and change the settings on power supply or load side. And wait
until battery release the protection.
c. Short circuit/Reverse polarity:
Check power cable and grounding cable connection whether is wrong or missing.
Check inverter/charger connected of a potential short circuit source.
d. High Voltage: If charging voltage above 28.5V, battery protection will turn on.
Solution: Check and change the settings on power supply side. And wait until bat-
tery release protection or discharge the battery.
e. Low Voltage: When the battery discharges to 23.2V or less, battery protection will
turn on.
Solution: Charge the battery by external charger, with voltage ≤28.5Vdc, current
≤55Amps.
