Do not damage the battery pack in such ways as dropping, deforming, impacting,
cutting or penetrating with a sharp object. It may cause a leakage of electrolyte or
fire.
Do not expose battery to open flame.
2.2.2 Response to Emergency Situations
The battery pack is composed of multiple batteries and designed to prevent the dan-
ger caused by malfunction.
If the user touches the inner material of the battery cells due to damage to the
shell, the following actions are recommended.
Inhalation: Leave the contaminated area immediately and seek medical attention.
Eye injuries: Rinse eyes with running water for 15 minutes and seek medical
attention.
Skin injuries: Wash the contacted area with soap thoroughly and seek
medical attention.
Ingestion: Induce vomiting and seek medical attention.
If a fire breaks out in the place where the battery pack is installed, perform the
following countermeasures:
Fire extinguishing media
Respirator is not required during normal operations.
Use FM-200 or CO²extinguisher for battery fire.
Use an ABC fire extinguisher, if the fire is not from battery and not spread to it yet.
Firefighting instructions
1. If fire occurs when charging batteries, if it is safe to do so, disconnect the
battery pack circuit breaker to shut off the power to charge.
2. If the battery pack is not on fire yet, extinguish the fire before the battery pack
catches fire.
3. If the battery pack is on fire, do not try to extinguish but evacuate people
immediately.
WARNING
There may be a possible explosion when batteries are heated above 150°C.
When the battery pack is burning, it leaks poisonous gases. Do not approach.
Effective ways to deal with accidents
On land: Place damaged battery into a segregated place and call local fire
department or service engineer.
In water: Stay out of the water and don't touch anything if any part of the battery,
inverter, or wiring is submerged.
Do not use submerged battery again and contact the service engineer.

3.2 Application Scenarios
SMILE-S5 is an AC-coupled all-in-one battery energy storage system (BESS). It can
help to achieve the optimal usage of renewable energy. SMILE-S5 can control the bi-
directional flow of electric power, work under auto/manual & time-of-use (TOU) modes,
charge/discharge the battery as per customer’s setting. Under the auto mode, SMILE-
S5 stores surplus renewable energy onto the battery and discharge battery to supply
power to local loads when renewable energy is not enough.
The standard schematic is as below:

4. Storage
4.1 Product Storage
The following requirements should be met if the product is not put into use directly:
1. Do not unpack the product.
2. The product should be stored in a clean and dry place and be protected from dust
and water vapor corrosion.
3. Place product according to the signs on the packing case during storage
A maximum of 2 layers can be stacked. To avoid personal injury or device damage,
stack products with caution to prevent them from falling over.
4. Store the product out of reach of children and animals.
5. Handle product with caution to avoid damage.
6. The storage environment requirements are as follows:
–Ambient temperature: -10~55°C, recommended storage temperature: 15~30°C
–Relative humidity: 15%~ 85%
–Place products in a place that is away from corrosive organic solvents and gases.
–Keep products away from direct sunlight.
–Keep products at least 2 meters away from heat sources.
8. The product in storage must be disconnected from external devices. The indicators
(if any) on the products should be off.
9. Products should be delivered based on the "first in, first out" rule.
10. The warehouse keeper should collect battery storage information every month and
periodically report the battery inventory information to the planning department. The
batteries that have been stored for nearly 6 months should be recharged timely.
11. If a lithium battery is stored for a long time, capacity loss may occur. After a lithium
battery is stored for 12 months in the recommended storage temperature, the
irreversible capacity loss rate is 3%~10%. It is recommended that batteries not be
stored for a long period. If the batteries need to be stored for more than 6 months, it is
recommended to recharge the batteries to 65～75% of the SOC. For example, they
should be recharged every 6 months at least, and must be recharged to at least 50%
of the SOC.
