2. Safety

2.1. Intended Use

The battery system is for residential and works with a photovoltaic system. It is a 48V Li-ion 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 LVS Minimum Configuration 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.

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 Overvoltages

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.

2.2.5. Caution of Weight

2.2.6. Notice of Property Damage

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.

NOTICE

Damage to the PDU due to sand, dust and moisture ingress

Sand, dust and moisture penetration can damage the PDU and impair its functionality.

•Only open the PDU 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.
