User Manual
1 Safety
· 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 using 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. 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.
3
1 Safety
Fire fighting
User Manual
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 an firefighting sandor CO2 extinguisher
to extinguish fire.
4 If the battery becomes involved in fire or is bent, damaged or breached in
any way, or if 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 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”.

User Manual
1 Safety
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 qualified electrician.

6 Commissioning
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.
– – End
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.
30
7 Decommissioning 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. – –
