the 120Ω terminator again.
5.4 DC power cable connection
5.4.1 Take out battery to battery power parallel cable.
5.4.2 Insert the Plug into the power socket until you hear the ‘click’ sound.

5.5 Connecting with inverter
Confirm inverter AC input and PV input is disconnected before wiring connection, and the DC/ signal switch of
inverter/charger is in off status.
5.5.1 Connecting Master battery Link IN port with inverter CAN or RS485 communication port via inverter
communication cable (Version I/II/III or customized).
5.5.2 Connecting battery OUTPUT (+) with inverter battery INPUT (+), battery OUTPUT (-) with inverter battery
INPUT (-), an external disconnection breaker between battery system and inverter is recommended, choose the
corresponding power cable pair and wiring them correctly.
Note:
Choose the suitable disconnection breaker considering the inverter power/current, rated voltage, tripping
characteristic etc.

The maximum communication cable length is required to be less than 15m between inverter/charge and battery.
The maximum power cable length is suggested to be less than 10m between inverter/charge and battery.
For Australia market:
In order to meet the AS/NZS 5139:2019 installation standard, a battery disconnection breaker is a mandatory
between each battery module and inverter, please choose appropriate breaker following the standard.
For other type of installation, please also follow the rules above to wiring your system.
The maximum tolerance current of each power cable and terminal is 125A, 100A for continuously is suggested,
please use corresponding number of power cable pairs according to the field configuration and local connection
requirements, standards, and directives.
5.6 Commissioning
5.6.1 Set the DIP address of the Master battery (and the Slave battery if there is any RS485 baud rate changed).
5.6.2 Switch on all battery modules, wait for 10s, make sure that only M/S led is on Master battery.
5.6.3 Turn on the breaker between the inverter and battery if there is any, then turn on the inverter/charger isolator.
5.6.4 Finish the setting on inverter/charger or any other control devices, if everything is correct, you are ready to
use the system.

For more information to connect with different inverter/charger, please contact your supplier for technical support.
If your system is a back-up or off-grid system, make sure your configuration can cover the worst situation to
avoid battery to be over-discharged.
5.7 Switch off battery
5.7.1 Turn off the inverter.
5.7.2 Turn off the disconnection breaker if there is any.
5.7.3 Turn off all batteries signal switch.

5. Troubleshooting and FAQ
Items Solution Measure
Unable to start
1. Power on battery and press RESET 6s to observe whether the
battery can be started.
2. Charge the battery use a charger or inverter to provide 54~57.6V
voltage and observe it can be started.
If the abnormal
status still alive after
above steps, please
contact your
supplier.
If there is any other
situation(s)
excluding in this
table, turn off the
fault battery, contact
your supplier.
Unable to
charge
1. Check whether the cable connection between the battery and the
inverter/charger is correct.
2. Check whether the inverter/charger setting is correct.
3. Check whether the battery is in charge protection mode, if yes, try
to discharge the battery.
Unable to
discharge
1. Check whether the cable connection between the battery and the
inverter/charger is correct
2. Check whether the battery occurs short circuit, reverse connection,
pre-charge failure during connection inverter etc.
3. Check whether the battery is in discharge protection mode, if yes, try
to charge the battery.
High/Low
temperature
1. Stop the battery system for a while, check whether the installation
location temperature meet the requirement.
2. Avoid continuous full charging and discharging.
High current
Check the configuration and parameters setting on the inverter/charger
is correct.
ALM always
on
1. Check the fault information on the inverter APP or display if possible.
Communicatio
n fail
1. Check the communication cable type is correct and is contacted well.
2. Check the DIP switch setting is correct.
3. Check the inverter protocol related setting is correct.
4. Check both battery and inverter are working properly.
Q1: Battery maximum SOC is 99% and never goes to 100%SOC during daily cycle use, why?
Generally, there is no effect to system on this point. BMS will calibrate the SOC to 100% when reached cut-off
current or trigger CHVP, however, to avoid battery from being overcharged and to extend the cycle life as longer
as possible, we left a room and set a charging profile to let battery not be charged at high voltage near full. Keep
float the battery for approximately 0.5~1 hour to calibrate.
Q2: ‘High voltage’ and ‘cell unbalance’ warning and alarm in rare cases, does it mean battery
is damaged?
No. This is not unusual and happened on new batteries that are not balanced yet, please lower the maximum
charge voltage (54.6V) and float the battery via grid or generator. If not solved, please contact your supplier.
Q3: When having multiple batteries in parallel connection, the battery on the end can’t be
fully charged.
Pay attention to your wiring diagram, please always follow the manual wiring advises and choose proper cable
size and pair.

Q4: The current is 0A when connecting with a very small load at the situation that having
multiple batteries in parallel connection, how to solve it?
Each BMS has a threshold current of 0.5A (~25W) before it begins to report, this leads the inaccurate display of
the current.
Q5: SOC suddenly jump to 100% during charging.
This is normal in off-grid application and usually happened on batteries that not been calibrated SOC for long
time, we suggest to fully charge the batteries per month.
6. Transport, Storage
 Do not violently shake, impact or squeeze, and prevent sun and rain during the transportation.
 Do light take and put and strictly prevent falling, rolling, and heavy pressure during loading and unloading.
 The battery should be placed in a dry, clean, dark, and well-ventilated indoor environment for long-term storage,
and the recommended storage temperature range is 15~30℃.
 No harmful gases, flammable and explosive products and corrosive chemical substances in the storage
location.
 The batteries should be stored and transported in close to 50% SOC, do not store over 80%SOC for long time.
 If do not use for a long time, the battery needs to be charged every 6 months.
 No fall down, no pile up over 6 layers, and keep face up.
7. Disposal of battery
Disposal of battery must comply with the local applicable disposal regulations for electronic waste and used
batteries, please review your local Battery recycling or management regulations or contact your supplier for more
information.
