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 Unable to start
Unable to charge
Unable to discharge
High/Low temperature High current ALM always on Communication fail

Solution
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.
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. 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. 1. Stop the battery system for a while, check whether the installation location temperature meet the requirement. 2. Avoid continuous full charging and discharging. Check the configuration and parameters setting on the inverter/charger is correct. 1. Check the fault information on the inverter APP or display if possible. 2.
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.

Measure
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.

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’ andcell unbalance’ warning and alarm in rare cases, does it mean battery is damaged?

Advanced battery for residential application

40

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.
