Do not expose battery to open flame.
2.2.2 Response to Emergency Situations
The battery pack comprises multiple batteries that are designed to prevent hazards
resulting from failures. However, AlphaESS cannot guarantee their absolute safety.
•If a user happens to be exposed to internal materials of the battery cell due to
damage on the outer casing, the following actions are recommended.
Inhalation: Leave the contaminated area immediately and seek medical attention.
Eye contact: Rinse eyes with running water for 15 minutes and seek medical
attention.
Contact with skin: 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-B3-PLUS is an AC-coupled all-in-one battery energy storage system (BESS). It
can help to achieve the optimal usage of renewable energy. SMILE-B3-PLUS 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-B3-PLUS will store 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:
Figure 3.1 SMILE-B3-PLUS System with PV
NOTE: For the AC coupled system with PV, if only install Grid CT, the system
cannot display power generated by PV inverter, electric energy production etc.
If there is no PV, the schematic is as below:
Figure 3.2 SMILE-B3-PLUS System without PV
NOTE: SMILE-B3-PLUS is not support for multiple INV combination and do
not support providing 3 phase output.

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
can be recharged every 6 months at least, and must be recharged to at least 50% of
the SOC.

6. Mounting
6.1 Requirements for Mounting
WARNING
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires.
•Do not mount the product in areas containing highly flammable materials or gases.
•Do not mount the product in potentially explosive atmospheres.
Basic Requirements
•SMILE-B3-PLUS and SMILE-BAT-5P are suitable for indoor and outdoor use.
•Do not install the product in a place where a person can easily touch it because
its housing and heatsink are hot during operation.
•Do not mount the product in areas with flammable or explosive materials.
•Do not mount the product at a place within children's reach.
•Do not mount the product outdoors in salt areas because it will be corroded there
and may cause fire. A salt area refers to the region within 500m from the coast or
prone to sea breeze. The regions prone to sea breeze vary depending on weather
conditions (such as typhoons and monsoons) or terrains (such as dams and hills).
Mounting Environment Requirements
•The product must be mounted in a well-ventilated environment to ensure good
heat dissipation.
•When mounted under direct sunlight, the power of the product may be derated
due to additional temperature rise.
•Mount the product in a sheltered place or mount an awning over the product.
•The optimal temperature range for the battery pack to operate is from15 to 30℃.
•Do not expose or place near water sources like downspouts or sprinklers.
•If the battery pack is mounted in the garage, then ensure that it is above the
height of the vehicle bumper and/ or door.
Mounting Structure Requirements
•The mounting structure where the product is mounted must be fireproof.
•Do not mount the product on flammable building materials.
•Ensure that the mounting surface is solid enough to bear the weight load.
•In residential areas, do not mount the product on drywalls or walls made of similar
materials which have a weak sound insulation performance because the noise
generated by the product is noticeable.
