1 Introduction
The Energy storage pack is an essential component of the photovoltaic power generation system. It
can provide electricity for the connected load, and it can also store photovoltaic solar modules, fuel
generators, or wind energy generators by charging the remaining energy in case of emergency.
When the sun goes down, energy demand is high, or there is a power outage, you can use the energy
stored in the system to meet your energy needs at no additional cost. In addition, the energy storage
Pack can help you achieve energy self-consumption and ultimately achieve the goal of energy
independence.
According to different power conditions, the energy storage PACK can output power during peak
power consumption, and can also store energy during low power consumption. Therefore, when
connecting the matching photovoltaic modules or inverter arrays, external equipment is required to
match the energy storage the working parameters of the pack to achieve the highest operating
efficiency. For a simple diagram of a typical energy storage system.

4.Installation
4.1 Selecting Mounting Location
Consider the following points to install the energy storage system:
• The energy storage system needs to be installed on a solid surface;
• It is recommended to place the energy storage system horizontally.
•To ensure air circulation and heat dissipation, please leave a gap about 200 mm away from the
side of the device.
•The ambient temperature should be between 0°C and 40°C, and the relative humidity should be
between 25% and 85% to ensure optimal operation.
•Install the battery module in a dry, protected, dust-free area with sufficient air circulation. Do not
operate in locations where the temperature and humidity are outside the specified range.

4.2 Mounting The PACK
WARNING!! Remember that this Pack is heavy so please be careful when removing
it from the package, or install it.
When installing each pack, use appropriate screws to fix it. After that, fix the equipment with bolts.
Step 1: When receiving the product, first check whether all parts are complete, if not, please report to
the Dealer.
Step 2: Remove the base and battery pack from the box. Lay the battery pack flat, and fix the base to
the bottom of the battery with M12 screws. After the base is installed, insert the accessories
and fix them with screws. (Note: The battery pack with the fixed base is different from other
modules, there is no connector at the bottom) As shown in the figure:

Step 3: Place the battery pack with the base against the wall, and the wall must be perpendicular to
the ground at 90°. (Note: the wall must be a loadbearing wall, otherwise the battery pack
cannot be installed on this wall) Fix the hanger on the battery holder. Once installed, secure
the position to the wall through the holes in the hanger. Remove the battery pack, drill a Ø8
mm depth 60 mm hole in the wall with a hammer drill, then screw the M8 blasting screw into
the wall. Move the battery pack to a suitable position and lock it with the nut.
Step 4: Drill holes with a Ø8 mm drill bit, the depth is about 60 mm, and the hole spacing is as follows:
(install the explosion screws after drilling)

Step 5: Align the pins, place the second battery module on top of the first battery module, and secure
the hanger with the screws. After installing the second battery pack, install the third and
fourth battery packs in sequence. Finally, install the main control box to complete the installa-
tion. as the picture shows:
Step 6: Open the side cover of the main control box, install the output cable and communication cable,
and connect to the inverter. Lock the side cover to complete the installation.
Step 7: Start the high pressure system. Press the power switch for 3S, when the red light of the switch
lights up, release your finger to start the system.
Step 8: Running the device, set the external charger or inverter parameters, please set according to
the corresponding operation manual.Can not exceed the rated parameter requirements.

Step 9: Stop operating the battery pack.
When it is necessary to stop the charging and discharging of the battery or troubleshoot,
please stop the external equipment first, cut off the input and output circuits, and then switch
the Changan power switch for 3S, when the power switch starts to flash. Release your finger
and the system shuts down.
Appendix I
Host soft operation
When the equipment manufacturer confirms that it is necessary, it can authorize to provide the
customer with the host software and operating instructions.

Appendix II
Troubleshooting
1. Battery pack stop work.
A: Turn on switch, be sure it is ON; if battery is low SOC. it need to charging in.
B: Battery pack low volt or enter sleep mode, there you will press down power switch button, then
charge in.
2. No communication, inverter can not received any DATA from BMS.
A: Check whether if communication cable is OK.
B: Replace the communication line.Please give feedback to the dealer and exchange it.
C: Check inverter or other device which connect to BMS, update it is firmware.
D: If the communication function needs to be upgraded, please consult the agent or manufacturer.
E: Confirm your inverter and battery protocol is correct, different protocol or different connection
will make a mistake.
3. Battery pack report SOC is mistake.
A: Inverter received Data from Master BMS, but it is SOC < total SOC, sample as: packs has 50 Ah
capacity, but inverter read DATA is 30 Ah. So you may check every cell Voltage unbalance.This
will lead to lower SOC.
B: SOC DATA has Large tolerance.
Discharge empty the battery first, then charge it fully with a small current, and learn to
discharge．Any pack is mistake we advice you read the BMS Data (When we authorize the
terminal to use)with host software. Then we reset the BMS and calibration．
4. How to turn on the Pack to discharge．
We recommend method is:
A: Reset the power switch,then restart bms system.
B: Turn on the power switch on the bottom/front panel.
WARNING: The operating parameters of the equipment cannot exceed the rated
working voltage and current of the Pack，exceed the rated volt and current, can
cause damage to the Pack or other failures.

5. Inverter or other external device can not connect the battery．
We recommend method is:
A: Check whether the working parameters of the device and battery are appropriate, and improper
parameters cannot be matched.
B: It is necessary to update BMS parameters and match the device, then Reset BMS and restart
your device.
6. Replace bad Pack.
There is a bad battery pack, it is need to replace, please connect your supplier, need professional
installers to operate it. We recommend replace all or make pack has same voltage and same
specification batteries pack.
NOTE: When replacing the battery, the same module needs to be replaced at the same time, and
the voltage should be the same．
7. Replace bad Pack.
Some parts can be obtained from the sales or agency, and the excess parts need to be purchased
separately.Be careful, turn off the power switch before replacing parts.
8. Need to place some safety device for keep a safe environment.
You’d keep a safe case for Pack and external device, Please place safety device, as: fire-fighting
sand, fire-fighting blankets, fire-fighting water pipes, Install Monitor sound, light, electricity, smoke
and other equipment.
WARNING:
Emergency process:
1. The external device catches fire and explodes:
