battery storage system, with the control module on itself. It could be operated in on-grid and off-grid
modes with compatible inverters.
The battery system could be connected to the Internet through network cable for maintenance and
firmware updating.
The battery system must only be used as stationary equipment.
The battery system is suitable for indoor and outdoor use under the conditions mentioned in Section
5.1.
The battery system must only be operated in connection with a compatible inverter. The list (BYD
Battery-Box Premium HVS & HVM Compatible Inverter List) of these inverters could be found at
www.bydbatterybox.com.
The battery system is not suitable for supplying life-sustaining medical devices. Please ensure that
no personal injury would lead due to the power outage of the battery system.
Alterations to the battery system, e.g., changes or modifications are not allowed unless the written
permission of BYD is achieved. Unauthorized alterations will void the guarantee and warranty
claims. BYD shall not be held liable for any damage caused by such changes.
The type label should always be attached to the battery system.
2.2. IMPORTANT SAFETY INSTRUCTIONS
The battery system has been designed and tested in accordance with international safety
requirements. However, in order to prevent personal injury and property damage and ensure long-
term operation of the battery system, please do read this section carefully and observe all safety
information at all times.
2.2.1. Battery Module Leakage
If the battery modules leak electrolytes, contact with the leaking liquid or gas should be avoided.
The electrolyte is corrosive, and the contact may cause skin irritation and chemical burns. If one is
exposed to the leaked substance, do these actions:
Inhalation: Evacuate the contaminated area, and seek medical help immediately.
Eye contact: Rinse eyes with flowing water for 15 minutes and seek medical help immediately.
Skin contact: Wash the affected area thoroughly with soap and water and seek medical help
immediately.
Ingestion: Induce vomiting and seek medical help immediately.
2.2.2. Firefighting Measures
The battery modules may catch fire when it is put into the fire. In case of a fire, please make sure
that an ABC or carbon dioxide extinguisher is nearby. Water cannot be used to extinguish the fire.
Full protective clothing and self-contained breathing apparatus are required for the firefighters to
extinguish the fire.

8
2.2.3. Battery Modules Handling and Storage Guide
•The battery modules and its components should be protected from damage when transporting
and handling.
•Do not impact, pull, drag, or step on the battery modules.
•Do not insert unrelated objects into any part of the battery modules.
•Do not throw the battery module into a fire.
•Do not soak the battery modules in water or seawater.
•Do not expose to strong oxidizers.
•Do not short circuit the battery modules.
•The battery modules cannot be stored at high temperatures (more than 50°C).
•The battery modules cannot be stored directly under the sun.
•The battery modules cannot be stored in a high humidity environment.
•Do not use the battery modules if it is defective, or appears cracked, broken or otherwise
damaged, or fails to operate.
•Do not attempt to open, disassemble, repair, tamper with, or modify the battery modules. The
battery modules are not user-serviceable.
•Do not use cleaning solvents to clean the battery modules.
2.2.4. Warning of Electric Shock
DANGER
Danger to life due to electric shock when live components or DC cables are touched
The DC cables connected to an inverter may be live. Touching live DC cables results in death or
serious injury due to electric shock.
• Disconnect the battery system and inverter from voltage sources and make sure it
cannot be reconnected before working on the device.
• Do not touch non-insulated parts or cables.
• Do not remove the terminal block with the connected DC conductors from the slot under
load.

9
2.2.5. Warning of Overvoltages
2.2.6. Caution of Weight
2.2.7. Notice of Property Damage
DANGER
Danger to life due to electric shock in case of overvoltages and if surge protection is missing
Overvoltages (e.g. in the event of a flash of lightning) can be further conducted into the building and
to other connected devices in the same network via the network cables or other data cables if there
is no surge protection. Touching live parts and cables results in death or lethal injuries due to
electric shock.
•Ensure that all devices in the same network and the inverteU are integrated into the
existing surge protection.
•When laying the network cables or other data cables outdoors, it must be ensured that a
suitable surge protection device is provided at the transition point of the cable from the
EDWWHU\system or the inverter outdoors to the inside of a building.
NOTICE
Damage to the BCU due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the BCU and impair its functionality.
•Only open the BCU if the humidity is within the thresholds and the environment is free of
sand and dust.
NOTICE
Damage to the battery system due to under voltages
•If the battery system doesn't start at all, please contact BYD local after-sales service
within 48 hours. Otherwise, the battery could be permanently damaged.
CAUTION
Risk of injury due to weight of the battery module
Injuries may result if the battery module is lifted incorrectly or dropped while being transported
or installed.
•Transport and lift the battery module carefully. Take the weight of the battery module into
account.
•Wear suitable personal protective equipment for all work on the battery system.

DANGER
Danger to life from electric shock due to live DC cables or connectors at the battery system
The DC cables connected to the battery system may be live. Touching the DC conductors or the
live components leads to lethal electric shocks.
•Do not touch non-insulated cable ends.
CAUTION
Risk of injury due to weight of the battery module
Injuries may result if the battery module is lifted incorrectly or dropped while being transported
or installed.
•Transport and lift the battery module carefully. Take the weight of the battery module into
account.
•Wear suitable personal protective equipment for all work on the battery system.

18
Additionally required installation material (not included in the scope of delivery):
•Two screws suitable for the support surface (diameter: 8 mm)
•Where necessary, two screw anchors suitable for the support surface and the screws.
Procedure:
1. Take the base from the package out, and install the four feet with a
wrench.
2. Put the installed base and feet along the wall, and keep the
distance of 12~19 mm between the wall and the base.
3. Take a battery module from the package out. Put one
battery module on the base. Pay attention to the direction of
the module. The blind-mating connectors on the battery
module and the base should be on the same side.
4. Repeat the operations for other battery modules.
5. Install the hanger (BCU part) to the BCU. To do this, insert the
screws (M5x14) through the hole on the BCU using a cylinder
screwdriver (8 mm) and tighten them (torque: 5.5 Nm).
6. Put the BCU on top of the battery modules.
Recommend to connect cables on the BCU first when five or
more than five battery modules are needed to be installed in
one tower.
7. Fix the connection between the battery module and the base,
between battery modules, and between BCU and battery
module. To do this, insert the screws (M4x14) through the
holes on them, using a Phillips screwdriver (PD2) and tighten
them (torque: 2 Nm).

8. Hold the hanger (wall part) where it intends to be mounted
on the wall and mark the position of the drill holes. Please
pay attention that there may be power cables or other supply
lines (e.g., gas or water) routed in the wall. Ensure that no
lines are laid in the wall, which could be damaged when
drilling holes.
9. Set the hanger aside and drill the marked holes.
10. Insert screw anchors into the drill holes if the support surface
requires them.
11. Secure the hanger using screws (recommended M8x40).
12. Fix the two hangers (wall part and BCU part) with M6X16
bolts and nuts, using a cylinder screwdriver (10 mm) to tighten it (torque: 8 Nm).
