2Device Installation
Installation Requirements
2.1
Installation Environment
Note：Dashed boxes indicate optional components.
If a battery pack is dropped or violently
impacted during installation, internal damage
may occur. Do not use such battery packs;
otherwise, safety risks such as cell leakage
and electric shock may arise.

4
Installation Environment Requirements
•The installation and use environment must meet relevant international, national,
and local standards for lithium batteries, and are in accordance with the local laws
and regulations.
•Ensure that the battery is not accessible to children and away from daily working or
living areas, including but not limited to the following areas: studio, bedroom,
lounge, living room, music room, kitchen, study, game room, home theater,
sunroom, toilet, bathroom, laundry, and attic.
•When installing the battery in a garage, keep it away from the drive way. It is
recommended that the battery be mounted on the wall higher than the bumper to
prevent collision.
•When installing the battery in a basement, keep good ventilation. Do not place
flammable or explosive materials around the battery. It is recommended that the
battery be mounted on the wall to avoid contact with water.
•Install the battery in a dry and well-ventilated environment. Secure the battery on a
solid and flat surface.
•Install the battery in a sheltered place or install an awning over it to avoid direct
sunlight or rain.
•Install the battery in a clean environment that is free from sources of strong
infrared radiation, organic solvents, and corrosive gases.
•For areas prone to natural disasters such as floods, debris flows, earthquakes, and
typhoons/hurricanes, take corresponding precautions for installation.
•Keep the battery away from fire sources. Do not place any flammable or explosive
materials around the battery.
•Keep the battery away from water sources such as taps, sewer pipes, and sprinklers
to prevent water seepage.
•Do not install the battery in a position where it is easy to touch as the temperature
of the chassis and heat sink is high when the battery is running.
•To prevent fire due to high temperature, ensure that the vents and the cooling
system are not blocked when the battery is running.
•Do not expose the battery to flammable or explosive gas or smoke. Do not perform
any operation on the battery in such environments.
•Do not install the battery on a moving object, such as ship, train, or car.
•In backup power scenarios, do not use the battery for the following situations：
a. Medical devices substantially important to human life.
b. Control equipment such as trains and elevators, which may cause personal injury.
c. Computer systems of social and public importance.
d. Locations near medical devices.
e. Other devices similar to those described above.
•Do not install the battery outdoors in salt-affected areas because it may corrode. A
salt-affected area refers to the region within 500 meters from the coast or prone to
sea breeze. The regions prone to sea breeze vary with weather conditions (such as
typhoons and monsoons) or terrains (such as dams and hills).

•The M6x60 expansion bolts delivered with the battery are mainly used for solid concrete walls
and concrete floors. If other types of walls and floors are used, ensure that the walls and floors
meet the load-bearing requirements (one battery expansion module weighs 50 kg) and select
the bolts by yourself.
•The power control module (DCDC) must be fixed on the wall. If the device is installed
in an area prone to earthquakes or vibration, you can mark the battery module
mounting holes and drill holes to install expansion bolts in step 2.
Keep a distance of
10 mm to 15 mm
between the support
and the wall surface.

•The following describes how to install the battery expansion modules for a 15 kWh model.
•The installation of battery expansion modules for 5 kWh and 10 kWh models is the same.
One battery expansion module is installed for a 5 kWh model, and two battery expansion
modules are installed for a 10 kWh model.
1. Install the battery expansion modules and power control module on the support.
Align the first battery
expansion module with
the support on the floor
support.
Install the connecting
pieces on both sides
and tighten the four
screws.
Install the remaining battery modules and power module from bottom to top. After
installing a module, secure the left and right connecting pieces, and then install the
next module.

Support
For floor-mounted installation, the base is 50 mm high. If waterproofing requirements cannot be
met, the battery can be installed on a wall. The mounting kits need to be purchased separately.
For wall- and floor-mounted installation, ensure that the load-bearing capacity meets the
requirements (one battery expansion module weighs 50 kg).

sequence, and secure
the ground cable using
a ground screw.
•Connect cables in accordance with local installation laws and regulations.
•Before connecting cables, ensure that the DC switch on the battery and all the switches
connected to the battery are set to OFF. Otherwise, the high voltage of the battery may
result in electric shocks.
3Internal Electrical Connections of the Battery
•Internal electrical cables are delivered with the battery, see the Packing List in the packing
case.
•The Amphenol terminal is used as the DC terminal between the power control module and
the battery expansion modules.

•When a communications terminal is connected to a single network cable, a waterproof rubber
plug must be installed. Do not install a cable with a diameter of 5 mm into a Ф7 mm rubber
plug.
•After inserting the terminal shell into the COM port, shake the terminal shell left and right
and pull it back to ensure that it is securely installed, and tighten the nut (ensure that the
rubber plug is tightly compressed). Otherwise, the waterproof performance is affected.

Installing DC Input Power Cables
Use dedicated insulated tools to connect cables. Ensure that battery cables are connected to
correct polarities. If the battery cables are reversely connected, the battery may be damaged.
1. You are advised to connect the battery terminals (BAT+ and BAT–) on the switch side to the
inverter and connect the other side to the cascaded battery.
2. For battery terminals, use the delivered Staubli MC4 positive and negative metal terminals and
DC connectors. Using incompatible positive and negative metal terminals and DC connectors
may burn the cables or damage the module. The resulting device damage will not be covered
under warranty.

•When laying out a signal cable, separate it from power cables and keep it away from strong
interference sources to prevent communication interruption.
•Ensure that the protection layer of the cable is inside the connector, that excess core wires
are cut off from the protection layer, that the exposed core wire is totally inserted into the
cable hole, and that the cable is connected securely.
•Use a plug to block the idle cable hole with the waterproof rubber ring, and then tighten the
locking cap.
•If multiple signal cables need to be connected, ensure that the outer diameters of the signal
cables are the same.
