8. Safety Instructions
The system has been designed and tested under international safety requirements. However, to
prevent personal injury and property damage and ensure long-term operation of the system, do
read this section carefully and observe all safety information at all times.
Battery Module Leakage
If the battery modules leak electrolyte, please avoid contact the leaking liquid or gas. If one is
exposed to the leaked substance, do these actions:
Inhalation: Evacuate the contaminated area, and seek for medical help immediately.
Eye contact: Rinse your eyes with clean water for at least 15 minutes and seek for medical help
immediately.
Skin contact: Wash the affected area thoroughly with soap and clean water, and seek for medical
help immediately.
Ingestion: Induce vomiting, and seek for medical help immediately.
Firefighting Measures
• In case of a fire, please make sure that a carbon dioxide extinguisher or Novac1230 or FM-200 is
nearby. Water cannot be used to extinguish the fire. (ABC is not effective for this battery firefight-
ing)
• Full protective clothing and self-contained breathing apparatus are required for the firefighters to
extinguish the fire.
Warning: Under >150
℃
environment, there is possibility that battery could explode
Handling and Storage Guide
• The battery modules and its components shall be protected from damage when it is in transporting
and handling
• Please take the weight of the battery module system into account during transportation and battery
module shall be lifted carefully
• Do not impact, pull, drag or step on the battery modules, either insert unrelated objects into any
part of the battery modules
• The battery module shall be kept away from a fire, water, strong oxidizers or solvents
• The battery modules cannot be stored in high temperature (> 60
℃
) or stored directly under the
sun, or in any high humidity environment.
• Do not use the battery modules if it is defective, or appears cracked, broken.
• Do not attempt to open, disassemble, repair, tamper with, or modify the battery modules without
official permission from GoodWe.
Warning: battery module damage may lead to electrolyte explosive air leakage, please
contact technical support immediately.
