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 areprone 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 Situations1.3.1 Leaking BatteriesAbuse/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 15minutes. 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 FireFire 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.

1 SafetyFire 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 BatteriesIf 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 BatteriesThe 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”.4
User Manual
1 Safety

6 Commissioning6.1 Inspection before CommissioningCheck 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 thepositive and negative terminals of the battery and inverter to avoid misconnection and reverse connection.6.2 Commissioning ProcedureIf 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.– – EndDuring 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 BatteryDecommission 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. – – EndContact SUNGROW to dispose of the battery.31
