All detailed work-related safety warnings and notes are specified at critical points in this
manual.
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.
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.
2
Risk of fire
•Do not expose the battery to temperatures in excess of 60°C.
•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.

1 Safety User Manual
3
•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.
1.3 Emergency Situations
1.3.1 Leaking Batteries
Abuse/misuse/damage of the battery may cause increasing of internal pressure in the
battery 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
minutes. 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 near the
battery can cause it to catch fire.
PPrrootteeccttiivvee eeqquuiippmmeenntt
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
FFiirree ffiigghhttiinngg
In the event of a fire, only qualified firefighters with appropriate protective
equipment are permitted to enter the room where the battery is located.
Battery fires can take up to 24 hours to fully extinguish. Consider allowing the
system 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 firefighting.
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 firefighting sand or CO2extinguisher to extinguish
fire.
4 If the battery becomes involved in fire or is bent, damaged or breached in any way,
or if you suspect that the battery is heating, use large amounts of water to cool the
battery. Do not try to extinguish the fire with a small amount of water. Always obtain
an additional water supply.
5 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
battery 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 described in ." "1.3.2 Fire
1 Safety User Manual
5
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.

6Commissioning
6.1 Inspection before Commissioning
Check the following items before starting the battery:
•Check that the battery system has been installed completely.
•Check that the appearance of the battery system is intact.
•Check that the battery system output wiring harness is correctly connected to the
positive and negative terminals of the battery and inverter to avoid misconnection
and reverse connection.
6.2 Commissioning Procedure
If all of the items mentioned above meet the requirements, proceed as follows to start
up the battery for the first time.
step 1 Connect all the switches on the AC and DC sides of the PCS.
step 2 Manually connect the DC breaker on the right side of the battery so that the BMS enters
the self-test state. The status indicator blinks in blue. Ten seconds later, press and hold
the status indicator for less than 2 seconds. Wait until the indicator is steady on in blue,
which indicates that the battery system is powered on and runs normally.
-- -- EEnndd
During commissioning, if there is a short-circuit fault in the battery system,
disconnect the power cable between the switch gear and the inverter, check
the battery system wiring, and eliminate the short-circuit fault point. Execute
step 2, check whether there is a fault in the battery (the indicator light is red),
and obtain fault information through iSolarCloud to contact SUNGROW to repair
the battery system.
31
7Decommissioning the Battery
Decommission the battery in the system after the inverter is decommissioned. Proceed
as follows to decommission the battery.
step 1 Press and hold the power button for 5 seconds until the DC breaker on the right side of
the battery is disconnected.
step 2 One minute after the DC breaker is disconnected, disconnect all cables between the
battery and other devices.
