11
STEP-5
Repeat STEP-3 through STEP-4 to insert more batteries (up to 12 batteries).
6.5 System Start up
· When connected with inverter, the inverter should be turned on first to avoid the current pulse of the
inverter increasing to the battery pack.
· All installation and operation must comply with local electrical standards.
· Check all power cables and communication cables carefully.
1. Turn on the POWER switch
Dial address selection
Definition of dial switch for parallel machine: When the battery pack is connected with multiple machines
in parallel, the dial switch can be used to distinguish different pack addresses. The hardware address can
be set by the dial switch on the board. Addresses 1, 2, 3, and 4 represent the online number of batteries
(only the host needs to be configured), 5, 6, 7, and 8 represent the slave address. The slave address
needs to be continuous, and can support up to 12 batteries in parallel.
Single machine address setting: 0001 0000
Parallel machine address setting: refer to the table below for the definition of dial switch.
For example, three machines are in parallel, and the dial switch example is as follows:
Master dial: 0011 0000, slave 1 dial: 0000 0001, slave 2 dial: 0000 0010

1) Before starting, please dial the code to the corresponding position according to the actual number of
parallel machines.
2) After pressing the start switch for 1s, all LEDs will be on and flashing, which indicates that the battery
is started normally. After pressing the reset switch for 3s, the battery will turn on the discharge function.
3) After the communication with the inverter is disconnected for 10s, the battery will turn off the output. If
it does not recover after 10 minutes, the battery will be shut down.
7 Commissioning
There are seven LED indicators on the front of the battery packs to show its operating status.
- Running LED indication
After startup, the running indicator light flashes, which indicates that the equipment is in normal
operation.
- Alarm LED indication
When the battery is in normal operation, the alarm LED is off, and after the fault occurs, the alarm LED is
always on.

9 Troubleshooting and Maintenance
9.1 Maintenance
1) Regularly check whether the service environment of the battery meets the requirements, and the
installation position should be far away from the heat source.
2) In case of one of the following situations, it needs to be charged in time:
- The battery is often under charged;
- The battery has been out of use or stored for more than 3 months.
3) Regularly check whether the battery and its supporting terminals, connecting cables and indicator
lights are normal.
9.2 Troubleshooting
When the red / green LED on the panel is flashing or normally on, it does not mean that the LV5200 is
abnormal, it may be just an alarm or protection. Please check the ‘LED status indicators’ in chapter 7 for
the detailed faulty definition before any trouble-shooting steps. In general, the alarm indication is normal
without manual intervention. When the alarm triggering state is removed, LV5200 will automatically
return to normal use.
- Problem determination based on the following points
1) Whether the green light on the power switch is on;
2) Whether the buzzer in BMS box rings;
3) Whether the battery system can be communicated with inverter;
4) Whether the battery can be output voltage or not.
- Preliminary determination steps
1) Battery system cannot work, when DC switch on and POWER on, the LED doesn’t light up or flash,
please consider contact the local distributor.
2) The LED display of BMS is normal, but it cannot charge and discharge. Observe the display screen
of inverter and there is no SOC. Please check whether the RS485 communication between BMS to
inverter is well connected. If the connection is good, please replace a RS485 communication cable. If
the SOC is still not visible on the inverter display screen, please contact the local distributor.
3) After the battery system is powered on, if you can see the alarm information on the LED and inverter
display screen at the same time, please contact the local distributor.
