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 leakage, please contact technical

support immediately.
