1.2 Safety Instructions
For safety reasons, installers are responsible for familiarizing themselves with the contents of this document
and all warnings before performing installation.
1.2.1 General Safety Precautions
Over-voltages or wrong wiring can damage the battery pack and cause deflagration, which can be extremely
dangerous.
All types of breakdown of the product may lead to a leakage of electrolyte or flammable gas.
Avoid installing the battery pack where flammable materials are stored. Do not install in places where
explosive gas or chemicals are present.
The utility grid, solar input, and battery voltage must be disconnected from the Battery Pack wiring. Wiring
must be carried out by a qualified person.
Battery Pack is not user serviceable.
1.2.2 Battery Handling guide
Do not expose battery to open flame.
Do not place the product nearby flammables. It may lead to fire or explosion in case of accident.

Do not store this product in a place exposed to direct sunlight.
A ventilated area is strongly recommended for handling the product.
Store at cool and dry place. (Do not store in greenhouses and storage areas for hay, straw, chaff, animal
feed, fertilizers, vegetables or fruit products.)
Store the product on a flat surface.
Store the product out of reach of children and animals.
Store the product where it should be minimal dust and dirt in the area.
Do not disconnect, disassemble or repair by unqualified personnel. Service must be made by qualified
personnel only.
Do not damage the unit in such ways as dropping, deforming, impacting, cutting or penetrating with a sharp
object. It may cause a leakage of electrolyte or fire.
Do not touch if liquid is spilled on the product. There is a risk of electric shock. Handle the battery wearing
the insulated gloves.
Do not step on the product or the product package. The product may be damaged.
Do not place any foreign objects on the top of the Battery Pack.
Do not put the battery pack upside down on the ground.
Do not connect anode and cathode terminal block opposite direction.
Do not charge or discharge damaged battery.
If the battery pack is installed in the garage then ensure the product is above the height of the vehicle
bumper.
The battery pack only be installed indoors. If installed outdoors, do not allow the battery pack to be exposed
to direct sunlight and water source as it may cause:
-Power limitation phenomena in the battery
(with a resulting decreased energy production by the system)
-Premature wear of the electrical/electromechanical components and mechanical components.
-Reduction in performance, service life and possible damage of the battery
Only use the product with supplier recommend inverter and solar charge controller （MPPT）.
Do not connect any AC conductors or Photo-voltaic conductors directly to the battery pack and should be
only connected to the Inverter and solar charge controller （MPPT）.

1.2.3 Response to Emergency Situations
The battery comprises multiple batteries and Sophisticated BMS that are designed to prevent hazards
resulting from failures. However, we cannot guarantee their absolute safety if battery is mishandled.
If a user happens to be exposed to internal materials of the battery cell due to damage on the outer casing,
the following actions are recommended.
Inhalation: Leave the contaminated area immediately and seek medical attention.
Eye contact: Rinse eyes with running water for 15 minutes and seek medical attention.
Contact with skin: Wash the contacted area with soap thoroughly and seek medical attention
Ingestion: Induce vomiting and seek medical attention.
If a fire breaks out in the place where the battery pack is installed, perform the following countermeasures:
Fire extinguishing media
Respirator is not required during normal operations.
Use FM-200 or CO2 extinguisher for battery fire.
Use an ABC fire extinguisher, if the fire is not from battery and not spread to it yet.
Firefighting instructions
If fire occurs when charging batteries, if it is safe to do so, power off the switch.
If the battery pack is not on fire yet, extinguish the fire before the battery pack catches fire.
If the battery pack is on fire, do not try to extinguish but evacuate people immediately
Effective ways to deal with accidents
On land: Place damaged battery into a segregated place and call local fire department or service engineer.
In water: Stay out of the water and do not touch anything if any part of the battery, inverter, or wiring is
submerged.
Do not use submerged battery again and contact the service engineer.
