2. Safety
2.1. Intended Use
The battery system is for residential use and works with a photovoltaic system. It is a high-
voltage Li-ion battery storage system, with acontrol module on itself. It could be operated in
on-grid, off-grid and backup modes with compatible inverters.
The battery system could be connected to the internet through a 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 occur due to the power outage of the battery system.

2.2.6. Caution of Weight

Shenzhen BYD Electronics Co., Ltd.
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.
•Wear suitable personal protective equipment for all
work
on the battery system.
•Observe all safety information of the inverter manufacturer.
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 inverter
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
battery
system or the inverter outdoors to the inside of a building.
Risk of injury due to the 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.
