1.3. Safe handling
1.3.1. Inverter
⚫ Only qualified electricians who have read and fully understood all safety regulations in this manual
can install, maintain, and repair the inverter.
⚫ When the inverter is working, do not touch the internal components or cables to avoid electric shock.
HS3 Series
12
⚫ When the inverter is working, do not plug in or out the cables.
⚫ Make sure that the AC input voltage and current are compatible with the rated voltage and current of
the inverter; otherwise, components might be damaged, or the device cannot work properly.
1.3.2. Battery
⚫ Operate and use the battery properly according to the user manual. Any attempts to modify battery
without the permission from SAJ will void the limit warranty for the battery.
⚫ The battery must be installed at a suitable location with sufficient ventilation.
⚫ For battery installation locations, especially rarely visited spaces like storerooms, attics and closets,
install smoke or multi-sensor fire detectors and interlink them with the central fire-alarm system.
⚫ Do not use the battery if it is defective, damaged, or broken.
⚫ Only use the battery with a compatible inverter.
⚫ Use batteries of the same type in an ESS. Do not mix the battery with other types of battery.
⚫ Make sure that the battery is grounded prior to use.
⚫ Do NOT pull out any cables or open the battery enclosure when the battery is powered on.
⚫ Only use the battery as intended and designed. Do not change any components in the battery.
⚫ If the user wants to expand the capacity later, it is recommended to add a cluster of batteries and use
them in parallel with the original batteries.
1.4. Emergency
Despite of its careful and professional protection design against any hazards, damage of the battery may
still possible. 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 and etc., the following actions are
recommended:
⚫ Eye contact: Rinse eyes with a large amount of running water and seek medical advice.
⚫ Contact with skin: Wash the contacted area with soap thoroughly and seek medical advice.
⚫ Inhalation: If you feel discomfort, dizziness, or vomiting, seek medical advice immediately.
⚫ 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.
⚫ Use an ABC fire extinguisher, if the fire is not caused by battery and not spread to it yet.
HS3 Series
13
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 but 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 may 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:
- Do not open damaged batteries.
- Do not damage the battery again (shock, fall, trample, etc.).
- Keep damaged batteries away from water (except to prevent an energy storage system from
catching fire).
- 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:
- 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.
- Overcharge of battery. Overcharge of battery may precipitate lithium metal. If the shell is
broken 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.
