STEP-2
Drill holes with electric drill, make sure the holes are deep enough (at least 50mm) for installation, and then
tighten the expansion tubes.
STEP-3
Install the expansion tubes in the holes, and tighten them. Then install the wall bracket by using the expansion
screws.
STEP-4
Hang the battery over the bracket, move the battery close to it, lower the battery, and make sure the 2 mounting
bars on the back are fixed well with the 2 grooves on the bracket.
·Wiring

11
STEP A
Connect BAT + to POS +, BAT – to NEG – respectively. Connect the battery communication network
cable to the lithium battery communication port of the inverter.
STEP B
Plug the power plug into any output socket on the left or right of the battery. Connect the communication
network cable to the CAN interface of the battery, connect the ground terminal of the battery with the
ground wire, and lock the nut.
Select an interface (CAN/RS485) based on the actual inverter interface type. Please choose L-1 or L-2.
Note: Parallel multiple batteries, please refer to the following steps.
STEP C
Plug the power line of the parallel battery into the remaining output socket, insert the communication line
of the parallel battery into LinkPort1, and lock the ground nut.

12
STEP D
Plug the power line of the parallel battery into the remaining output socket, insert the communication line
of the parallel battery into LinkPort0, and lock the ground nut.
STEP E
Repeat STEP C through STEP D to insert more batteries (up to 12 batteries).
6.5 System Start up
·When connected to the inverter, turn on the battery first to ensure that the battery voltage output is
normal, then turn on the inverter.
·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 address switch for parallel batteries: When the battery pack is connected with multiple
batteries in parallel, the address switch can be used to distinguish different pack addresses. The
hardware address can be set by the address 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 battery address setting: 0001 0000
Parallel batteries address setting: refer to the table below for the definition of address switch.
For example, three batteries are in parallel, and the address switch example is as follows:
Master dial: 0011 0000, slave 1 dial: 0000 0001, slave 2 dial: 0000 0010

13
Note: “1”indicates that the Dip switch is “ON”, “0” indicates that the Dip switch is “OFF”. And it also
indicates the position of the Dip switch. For example, “0001 0000”indicates that the 4th Dip switch is
"ON"，the rest are all "OFF".
1) Please change the address switch in the right position accordingly base on the system battery
quantity before power on battery.

8. Exclusion
The warranty shall not cover the defects caused by normal wear and tear, inadequate maintenance,
handling, storage faulty repair, modifications to the battery or pack by a third party other than
manufacturer or manufacturer agent, failure to observe the product specification provided herein or
improper use or installation, including but not limited to the following.
·Damage during transport or storage.
·Incorrect Installation of battery into pack or maintenance.
·Use of battery pr pack in inappropriate environment.
·Improper, inadequate, or incorrect charge, discharge or production circuit other than stipulated
herein.
·Incorrect use or inappropriate use.
·Insufficient ventilation.
·Ignoring applicable safety warnings and instructions.
·Altering or attempted repairs y unauthorized personnel.
·In case of force majeure (ex: lightning, storm, flood, fire, earthquake, etc.).
·There are no warranties-implied or express-other than those stipulated herein. manufacturer shall
not be liable for any consequential or indirect damages arising or in connection with the product
specification, battery or pack.
9. Troubleshooting and Maintenance
9.1 Maintenance
1) It is recommended that the battery storage time is not more than 6 months.
2) It is required to charge the battery at least once every 6 months, for this charge maintenance
make sure the SOC is charged to higher than 70%。
In the condition of 90% charging. It is recommended that the customers use low-voltage
inverter and fill the battery every half month, otherwise the SOC will be deviated.
3) Every year after installation. The connection of power connector, grounding point, power cable and
screw are suggested to be checked. Make sure there is no loose, no broken, no corrosion at
connection point. Check the installation environment such as dust, water, insect etc. Make sure it is
suitable for IP21 battery system.
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 is on;
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.
