4.2. Battery Management System (BMS)
4.2.1. Voltage Protection
Low Voltage Protection in Discharging：
When any battery cell voltage or total voltage is lower than the protection value
during discharging, the over-discharging mode is activated, and the battery
buzzer makes an alarm sound. Then battery system stops supplying power to the
outside. When the voltage of each cell back to rated range, the protection is
over.
Over Voltage Protection in Charging：
Battery will stops charging when total voltage or any battery cell voltage reaches
the rated protection value during charging stage. When total voltage or all cell
back to rated range, the protection is over.
4.2.2. Current Protection
Over Current Protection in Charging：
When the charge current ＞45A, current limit protection mode is activated,
current will be limited to 5A，protection is removed after rated time delaying 10S.
Circulate like this until the current is lower than 45A.
Over Current Protection in Discharging：
When the discharging current is greater than the protection value 55A, the
battery buzzer alarms and the system stops discharging. Protection is removed
after rated time delaying 1min.
Caution:
The buzzer sound alarm setting can be manually turned off on the background
software, and the factory default is on.

7
4.2.3.Temperature Protection
Low/Over temperature protection in charging：
When battery’s temperature is beyond range of -5℃~+55℃during charging,
temperature protection is activated, device stops charging.
The protection is over when temperature back to rated working range.
Low/Over temperature protection in discharging：
When battery’s temperature is beyond range of -20℃~+55℃during discharging,
temperature protection is activated, device stops supplying power to the
outside.
The protection is over when temperature back to rated working range.
4.2.4.Other Protection
Short Circuit Protection：
When the battery is activated from the shutdown state, if a short circuit occurs,
the system starts short-circuit protection for 60 seconds.
Self-Shutdown：
When device connects no external loads and power supply and no external
communication for over 72 hours, device will dormant standby automatically.
Caution
Battery’s maximum discharging current should be more than load’s maximum
working current.
4.3. DIP switch
When the batteries are connected in parallel, the host communicates with the
slaves through the CAN interface. The host summarizes the information of the
entire battery system and communicates with the inverter through CAN or 485.
The connection mode is divided into the following two cases:
1- The communication cable from the host CAN IN to the inverter comm port
should be the correct one.
2- DIP configuration depending on Inverter type:

8
- Inverter: TURBO ENERGY HI, GOODWE, VICTRON, SOFARSOLAR, SMA, SOLIS,
LUX, IMEON, INFINISOLAR, SUNGROW, RENAC, DELIOS, GROWATT HVM
Master Slaves
- Inverter: VOLTRONIC Axpert-VMIII/Axpert King, Growatt SPH/SPA
Master Slaves
- Inverter: GROWATT SPH/SPA
Master Slaves
- Inverter: GROWATT SPF HVM

3- If the energy storage system has only one Lithium Series 48V 2.4 kWh, it is
the host itself.

1. Place the Lithium Series 48V 2.4
kWh unit on the rack bracket as
shown in the figure and push the
device into the cabin at the
installation position. (The cabinet
structure in the figure is for
reference only)
2. Secure the Lithium Series 48V 2.4
kWh unit to the rack with a nut
through the mounting holes top on
the hanging ears of the unit.

Installation method 2: With simple bracket installation
4.4.3. Electrical installation
Before connecting the power cables, use multimeter to measure cable
continuity, short circuit, confirm positive and negative, and accurately mark the
cable labels.
Measuring methods：
•Power cable check: select the buzzer mode of multimeter and
detect both ends of the same color cable. If the buzzer calls, it
means the cable is in good condition.
•Short circuit judgment: choose multimeter resistor file, probe the
same end of positive and negative pole, if the resistor shows infinity,
means that the cable is available.
•After visual testing of power line is connection, the positive and
negative poles of the battery shall be connected respectively to
the positive and negative poles of the opposite terminal.
It is better to add a circuit breaker between the inverter and the battery system.
The selection of the circuit breaker requires:
1. Place the Lithium Series 48V
2.4 kWh and brackets as
shown in the figure and insert
it into the brackets. Use 4
screws to fix the module on
the front bracket.
2. Install another pair of
brackets on the first one,
fixed by buckles between
them.
3. Insert the second one
Lithium Series 48V 2.4 kWh
into the brackets and
repeat for more batteries.

BAT cable is from master CAN OUT to slave1 CAN IN, slave1 CAN OUT to slave2
CAN IN…
Each pair of power cable, it is limited continuous current is 120A, so if the inverter
Max. work current more than 120A, please add power cable according to the
proportion.

5. Use, maintenance and problem solving
5.1. Commissioning and use of the equipment
After completing the electrical installation, follow these steps to start the battery
system:
1. Refer to the description of the DIP switch of 4.2. to prepare the battery
module before starting up, then press the ON/OFF button to the ON
position, next press and hold the SW button for 3 seconds.
2. After the indicator self-test, the RUN indicator will light and the SOC
indicator will be on (100% SOC status in the figure)

14
Caution
After pressing the power button, if the battery status indicator on the front panel
continues to be red, please refer to the "5.2 Alarm description and processing ".
If the failure cannot be eliminated, please contact the dealer timely.
3. Use a voltmeter to measure whether the voltage of the circuit breaker
battery access terminal is higher than 42V, and check whether the
voltage polarity is consistent with the inverter input polarity. If the circuit
breaker battery input terminal has a voltage output and is greater than
42V, then the battery begun to work normally.
4. After confirming that the battery output voltage and polarity are correct,
turn on the inverter, close the circuit breaker.
5. Check if the indicator of the inverter and battery connection
(communication indicator and battery access status indicator) is normal.
If it is normal, successfully complete the connection between the battery
and the inverter. If the indicator light is abnormal, please refer to the
inverter manual for the cause or contact the dealer.
6. Battery modules can be connected in parallel up to 40 units.

6. Appendix
6.1. Safety instructions
1. Please read the battery instructions before use.
2. Keep the battery away from high voltage and out of reach of children.
3. In operation, the battery should be kept in the set temperature ranges
(between -20ºC and 50ºC) and a humidity less than 85%.
4. During handling, be very careful to avoid bumps/falls of the battery.
5. Be careful not to touch the contacts at the same time.
6. The battery, at the end of its useful life, requires a recovery process, not
disassemble it.
7. Avoid locating batteries in damp places to avoid danger.
8. When not in use for a long time, store the battery intact and let the battery
be half charged. Wrap the battery with non-conductive material to avoid
direct contact of the metal. Store the battery in a cool, dry place.

the battery without safety conditions.
2. Never short-circuit the poles of the battery. Avoid contact of positive and
negative poles with metals.
3. Keep the batteries away from fire and extreme temperatures. Monitor the
distance to thermal bulbs, stoves, etc.
4. Keep the battery away from the water. Always be careful that the battery
is not located in damp places where the dew point can be reached.
5. Do not use batteries that have physical damage that may be due to falls
or bumps.
6. Do not weld near the battery.
7. Overheating will result in the loss of the protective function of its life cycle,
even, it could render the battery useless and in extreme cases self-ignition
of the battery occurs.

18
8. Never connect this battery in series and connect it in parallel only with
identical batteries up to a maximum number of 6.
9. If the battery has liquid leakage, avoid contact with it completely. It can
be harmful to the skin, and if you touch the eyes, wash, and go to the
hospital immediately for treatment.
