2.3 Principle
After starting the system, when the inverter works at on-grid mode, the photovoltaic solar energy will give priority
to supply the load if the photovoltaic is sufficient; if there is any surplus, it can be used to charge the battery first;
and for more surplus, it will be fed back to the grid. If the photovoltaic solar energy is insufficient or at night, it
will automatically switch to the battery to deliver electric power to the load and when it run out of energy also,
the excess power will be supplied by the grid.
When the inverter works at off-grid mode, both the load and battery are charged by photovoltaic solar energy
during the day, and the load will be supplied by the battery at night. Below is the overall framework of the system:

Please check again by on-site personnel on the following conditions or equipment whether meet the
requirements before installation:
• Check if there’s enough space for installation, and if the load-bearing capacity of the bracket or cabinet meets
the weight requirements
• Check whether the power cable used meets the maximum current requirement for operation;
•Check whether the overall layout of power supply equipment and batteries at the construction site is
reasonable;
• Check whether the installer is wearing anti-static wristband
• Check whether there’re two people on the construction site for installation work
• Check if there’s potential risks at location of installation site, e.g. flooding, sun exposure, corrosion, and salt
spray
4.3.2 Installation procedures
4.3.2.1 Get the battery ready
1．Get the battery ready, ensure all the battery indicator is in OFF, and confirm whether the appearance of the
battery is normal;
2．Confirm both the battery breaker and the system breaker that connected the battery with inverter are
disconnected.
3. Turn on the signal switch of the battery, observe whether there is alarms on the panel, measure it with
multi-meter and record battery voltage, then check if it meets the parallel standard: open circuit voltage
difference < 0.5V;
4. After confirming that everything is OK, turn off the battery and put it at the installation preparation area for
ready-to-install:
Placement description:

Version: V02 Page 17 of 21
4.3.2.2 Structure and electrical installation
1. Get the cabinet ready and assemble it as integrator requested to ensure the cabinet is installed horizontally and
reasonable location layout;
2. Prepare all the battery packs, place the batteries on the cabinet tray via manual-lifter, and push the batteries
into the cabinet, then fix the battery mounting ears to the cabinet through the crown-nuts;
3. Please double check the battery is in shut down and disconnect the circuit breaker, unscrew the
positive/negative terminal bolts of the battery pack, then connect the batteries to the positive/negative bus bar
through cables;
4. Unscrew the grounding screw, connect the battery and the grounding bus bar of cabinet through the
yellow-green flexible wire to ensure that all connections are reliable
5. Connect the CAN communication interface between the batteries, set the dial switch address as Table 3-5, and
insert the matching resistance terminal into the CAN port at the end of battery, as Figure 4-4

Version: V02 Page 18 of 21
6. Connect the RS485 port of the master battery module to the battery communication interface of the inverter,
meanwhile, connect the bus bar of the battery cabinet and the battery input of the inverter through the system
breaker;
7. Starting from the master, turn on all battery modules by pressing the reset button, close the battery breakers
one by one, and observe whether the breakers can’t be closed and any overcurrent occurs during the process. If
all works normally, go to the next step; If there’s battery breaker can’t be closed or overcurrent occurs, please
measure the battery voltage separately to evaluate whether it’s caused by a large voltage difference.
4.3.2.3 Enabling system
After completing above all steps, turn on the system breaker between the battery cabinet and the inverter, run
the inverter and open the setting menu, then select 'Lib’ in the battery type, and press the battery on switch to
measure the battery voltage , If normal output then turn on the battery to access breaker. At the same time, check
whether the communication is normal, if all is ready then enable the system.

5. Maintenance and Abnormality handling
5.1 Activation and dormancy
5.1.1 System activation
If it meets any of the following conditions when the system is in low-power mode, the system will exit from it and
enter the normal running mode:
When the charger is connected, the output voltage of the charger need to higher than 48V.
1) Turn on the power button.
2) In the case of battery in sleep mode(except battery over-discharge, battery damage, etc.), the monitoring
software can wake up the battery.
Remark: The battery will be in low-power mode after cell or PACK reach over-discharged protection, wake up
every 4 hours to turn on the charge and discharge MOS. If it can be charged, it will exit from dormancy mode for
charging normally; if it can’t be charged after 10 consecutive automatic wakeups, it will no longer wake up
automatically
When the system is defined as charging ends, the recovery voltage still not reach after 2 days of standby (stand-by
time set value), then it will be forced to re-charging till the end of charging again.
5.1.2 System Dormancy
When any following conditions occurs, the system will be in Low Power mode:
1) The over-discharge protection of the cell or PACK is not released within 60 seconds
2) The lowest cell voltage is lower than the dormancy voltage, and the duration up to the dormancy delay time
(meanwhile, it meets the requirements of no communication, no protection, no balance, and no current).
3) Shut down through the upper computer.
4) Make sure that the input terminal disconnect to external voltage before entering dormancy mode, otherwise it
will fail to access to Low Power mode.
5.2 Regular maintenance
1) Regularly check whether the usage environment meets the requirements, and ensure the installation location is
far away from heat sources.
2) Check whether the charging and discharging of the battery pack are normal. You need to recharge in time for
