Safety
2.1. Intended Use
The system is for residential and small business use and works with a photovoltaic system. It is a 48V Li-ion battery storage system, with a control module on itself. It could be operated in either off-grid or on-grid mode with compatible inverters.
The system could be connected to the Internet through network cable for maintenance and software updates.
The system must only be used as stationary equipment.
The system is suitable for indoor use only.
The system must only be operated in connection with a compatible inverter. The list (BYD Battery-Box Premium LVL Minimum Configuration List) of these inverters could be read on our websites.
The 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 system.
Alterations to the BYD system, e.g., changes or modifications are not allowed unless the written permission of BYD is achieved.
The enclosed document is an integral part of this system. Keep the documentation in a convenient, dry place for future reference and observe all instructions contained therein.
The type label should always be attached to the system.
2.2. IMPORTANT SAFETY INSTRUCTIONS
The 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 system, please do read this section carefully and observe all safety information at all times.
2.2.1. Battery module leakage
If a battery module leaks 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 a 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 their components should be protected from damage when transporting and handling.
- The weight of the system may cause injury risk, and please take the weight of the system into account while the system is transported and lifted carefully.
- 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.
