• The safety instructions in this manual cannot cover all the precautions that
should be followed. Perform operations considering actual onsite conditions.
• SUNGROW shall not be held liable for any damage caused by violation of the
safety instructions in this manual.
• When installing, operating, and maintaining the device, comply with local laws
and regulations. The safety precautions in this manual are only supplements
to local laws and regulations.
1.1 Notices for Safe Use
Read all safety instructions carefully prior to any work and observe them at all times when
working on or with the battery. Failure to observe the precautions described in this section
can cause serious injury to persons or damage to property.
Risk of explosion
• Do not subject the battery to any strong force.
• Do not mechanically damage the battery (pierce, deform, strip down, etc.)
• Do not heat the battery or dispose of the battery in a fire.
• Do not install the battery in potentially explosive environments.
• Do not place the battery in water or other liquids.
2
Risk of fire
• Do not place the battery near a heat source, such as direct sunlight, a fireplace,
a thermally uninsulated wall exposed to sunlight, hot water, or a heater.
• Keep sources of ignition such as sparks, flames, and smoking materials away
from the battery.
Risk of electric shock
• Do not disassemble the battery.
• Do not handle a wet battery or use wet tools.
• Do not soak the battery in water or expose it to moisture or liquids.
• Keep the battery away from children and animals.
• Wear suitable clothing, guards and gloves to prevent you from direct contact
with the DC voltage.
• Use insulated tools during working with battery.
• Set aside metal jewelry before working on the DC circuit.
1.2 Battery Handling Information
Comply with local standards for use with the battery.
Any man-made damage will void the limited warranty for the battery. Handle the battery with
care to protect it from damage.
• Use the battery only as intended and designed.
• The battery must only be installed at a suitable location.
• Make sure the battery is well connected to ground before use.
• Do not use the battery if it is defective, appears cracked, broken or damaged, or fails to
operate.
• Do not use the battery together with other types of batteries.
• Do not pull, drag or step on the battery.

1 Safety User Manual
3
• Do not damage the sheath of cables, wire harness and connectors.
• While the battery is charged, used and stored, keep it away from materials that are prone
to electric discharge, including static discharge.
• Keep the battery away from babies and children to avoid any accidents.
• Cover terminals with insulating tape before proper disposal.
• Avoid direct contact with rain, snow, and water, and prevent the battery from falling and
mechanical impact during battery transportation.
1.3 Emergency Situations
1.3.1 Leaking Batteries
Abuse/misuse/damage of the battery may cause increasing of internal pressure in the bat-
tery cells. It may result in the electrolyte venting. In the event that battery electrolyte is
released:
• Do not enter the room under any circumstance.
• Avoid contact with the leaking liquid or gas.
• Call the Local Emergency number or Fire Brigade if necessary.
If one is exposed to the leaking substance, follow the suggestions below to minimize the
chance of injury:
• Inhalation: Evacuate the contaminated area, and seek medical aid.
• Eye contact: Rinse eyes with copious amounts of water for at least 15 minutes, and seek
medical aid immediately.
• Skin contact: Wash the affected area thoroughly with plenty of water for at least 15 mi-
nutes. If possible, remove or saturate contaminated clothing with water. Seek medical
aid if the patient is distressed.
• Ingestion: Induce vomiting, and seek medical aid immediately.
Wipe out the contacted area with a sponge or cloth that is soaked in water until you obtain
medical aid. These materials can damage skin and eyes, causing blindness.
1.3.2 Fire
Fire may occur with the battery despite its careful design. Likewise, a fire or unusually high
temperatures near the battery can cause it to catch fire.
Protective equipment
A respirator is not required during normal operations.
In the event of a fire, hazardous fumes including carbon monoxide, carbon dioxide, and/or
various hydrocarbons may be emitted. To comply with the Personal Protective Equipment
Directive (89/686/EEC), use a full-face self-contained breathing apparatus (SCBA) with full
protective gear during fire fighting.
User Manual 1 Safety
4
Fire fighting
In the event of a fire, only qualified firefighters with appropriate protective equip-
ment are permitted to enter the room where the battery is located.
It may take a long time to completely extinguish the fire. Consider allowing the sys-
tem to burn. Smoke indicates that the battery is still burning. Always note that
there is a risk of the battery re-igniting.
Proceed as follows for fire-fighting.
1 Shut off any connected power system or electronics such as the battery, battery isolator,
PV DC isolator(s), AC isolator, solar supply main switch and normal supply main switch.
2 Perform an adequate knock down on the fire before entering the incident’s hot zone.
3 If the battery catches on fire, use fire-fighting sand, CO2extinguisher, or other emer-
gency fire extinguishing equipment approved by fire fighters to extinguish the fire.
4 If the fire is not from the battery and has not spread to it yet, use an ABC fire extinguisher
to extinguish the fire. Remove batteries and other ignition sources from the scene of a
fire.
1.3.3 Wet Batteries
If the battery is submerged in water, do not let people access it, and then contact Sungrow
or an authorized service partner for technical support.
If a battery is submerged in water or flooded, first, switch off all circuit breakers in the system
to cut off the power supply to the battery. Wait until floodwaters subside and do not approach
near battery. If someone needs to go into the flooded water, wear insulated full length rubber
boots and gloves.
Do not use a flooded battery again.
1.3.4 Damaged Batteries
The battery consists of lithium-ion cells. These are considered dry cell batteries. If the bat-
tery is damaged, only a small amount of battery fluid can leak.
A damaged battery can cause rapid heating of the battery cells. If you notice smoke coming
from the battery area, assume that the battery is burning and take appropriate action as de-
scribed in "1.3.2 Fire".
Damaged batteries are dangerous and must be handled with extreme caution. They are not
fit for use and may pose a danger to people or property. If a battery seems to be damaged:
1 Pack it in its original container.
2 Store it in a separated room like the installation place.
3 Contact SUNGROW.

• Preferably, keep the temperature in the range of 15℃to 25℃. Store the battery within
the temperature range of -10℃to 35℃for no more than 6 months.
• The storage relative humidity must be always between 0 and 95%, non-condensing.
• Store the battery in a clean and dry place, without exposure to sunlight and rain. The
storage location must be free of harmful gases, flammable/explosive products and corro-
sive chemicals. The battery should be prevented from mechanical impact, high pressure,
high-intensity magnetic field and direct exposure to sunlight.
• Pay attention to the harsh environment, such as sudden cooling/heating and collision, to
avoid damage to the battery.
• The number of stacking layers of battery modules with package must not exceed 6. It is
strictly forbidden to directly stack batteries without package.
• Regularly inspect the package for damage and insect bites. If any damage is found, the
product should be replaced immediately.
• The packing should be upright.
• If stored for more than 6 months under the specified conditions, the battery needs to be
charged once, until the system SOC is 50% to 80%. Preferably, use an PCS for forced
charging.
Store the battery for no more than three years; otherwise, over 20% of the ca-
pacity may lose irreversibly.
