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.
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
Follow local standards to use the battery.
1 Safety Instructions User Manual

3
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.
• Do not leave any foreign objects inside the battery.
• Do not repair or modify the battery. It is not user serviceable.
• Do not pull out any cables when the battery is powered on.
• 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.
User Manual 1 Safety Instructions

4
• 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.
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 fire, turn off the battery MCB immediately.
4 The use of fire extinguishing sand, carbon dioxide fire extinguishers can briefly extin-
guish open fires, water is the best way to control the spread of fire, but the use of water
fire extinguishing needs to wear electrical insulation protective equipment to avoid elec-
tric shock.
5 Since the battery may re-ignite at any time due to the high temperature of the internal
chemical reaction, please use a large amount of water to continuously cool the battery
for 30-60min after extinguishing the open flame, and wear electrical insulation protective
equipment to avoid electric shock during this process.
6 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.
A damaged battery may release dangerous material and a flammable gas mixture.
Never try to repair the battery even if you are a qualified electrician.
