2.3 Emergency situation
Despite of its careful and professional protection design against any hazard results,
damage of the battery may still occur. If a small amount of battery electrolyte is
released due to a serious damage of the outer casing; or if the battery explodes due to
not being treated timely after a fire breaks out nearby, and leaks out poisonous gases
such as carbon monoxide, carbon dioxide etc., the following actions are recommended:
1) Eye contact: Rinse eyes with a large amount of running water and seek medical
advice
2) Contact with skin: Wash the contacted area with soap thoroughly and seek
medical advice
3) Inhalation: If you feel discomfort, dizziness or vomiting, seek medical advice
immediately.
4) Use a FM-200 or Carbon Dioxide (CO2) fire extinguishers to extinguish the fire if
there is a fire in the area where the battery pack is installed. Wear a gas mask and
avoid inhaling toxic gases and harmful substances produced by the fire.
5) Use an ABC fire extinguisher, if the fire is not caused by battery and not spread to
it yet.
Warning
!

If a fire has just occurred, try to disconnect the battery circuit breaker and
cut off the power supply first, but only if you can do so without endangering
yourself.

If the battery is on fire, do not attempt to extinguish the fire and evacuate
the crowd immediately.

Potential danger of damaged battery:
Chemical Hazard: Despite of its careful and professional protection design against any
hazard results, rupture of battery shall still occur due to mechanical damage, internal
pressure etc., and may result in a leakage of battery electrolyte. The electrolyte is
corrosive and flammable. When there is fire, the toxic gases produced will cause skin
and eyes irritation, and discomfort after inhalation. Therefore:
1) Do not open damaged batteries.
2) Do not damage the battery again (shock, fall, trample, etc.).
3) Keep damaged batteries away from water (except to prevent an energy storage
system from catching fire).
4) Do not expose the damaged battery to the sun to prevent internal heating of the
battery.
Electrical hazard: The reason of fire and explosion accidents in lithium batteries is
battery explosion. Here are the main factors of battery explosion:
1) Short circuit of battery. Short circuit will generate high heat inside battery, resulting
in partial electrolyte gasification, which will stretch the battery shell. The
temperature reaching ignition point of internal material will lead to explosive
combustion.
2) Overcharge of battery. Overcharge of battery may precipitate lithium metal. If the
shell is broken, it will come into direct contact with the air, resulting in combustion.
The electrolyte will be ignited at the same time, resulting in strong flame, rapid
expansion of gas and explosion.

3 Introduction
3.1 Scope of application
ACU series is used in energy storage retrofits and is a new type of AC coupled energy
storage system. The built-in lithium battery inside ACU can be expanded in capacity
according to user demands, and the modular design of the slave device makes it easy to
install wiring. ACU can has a capacity expansion by using TSOL-B Expansion Battery.
In daytime, solar power supports the loads first while the surplus power will be stored by
ACU, to improve self-consumption rate.
In peak power price hours, power from ACU supports the loads; while in valley power
price hours, ACU is charged by the grid. Finally, a balance could be realized. In case of
grid fault, ACU will make sure no outage in the loads, achieving UPS function
ACU can has a capacity expansion by using TSOL-B Expansion Battery.
