2.1 Intended Use of the Inverter
The inverter, the battery pack, the energy meters make up a system for optimization of
self-consumption in a household. The inverter is equipped with two MPP trackers (only
for S5&S3.6, SMILE-G3-B5 does not have MPPT) and converts the direct current from
the PV array into grid-compliant single-phase current and feeds it into the utility grid.
The battery pack is used for the intermediate storage ofthe energy.
The product is suitable for indoor and outdoor use.
The product must only be operated with PV arrays of protection class II in accordance
with IEC 61730, application class A. The PV modules must be compatible with this
product.
PV modules with a high capacity to ground must only be used if their coupling
capacity does not exceed 1.0 μF.
All components must remain within their permitted operating ranges at all times.
Use this product only in accordance with the information provided in the enclosed
documentation and with the locally applicable standards and directives. Any other
application may cause personal injury or property damage.
Alterations to the product, e.g. changes or modifications, are only permitted with the
express written permission of AlphaESS. Unauthorized alterations will void
guarantee and warranty claims. AlphaESS shall not be held liable for any damage caused
by such changes.
Any use of the product other than that described in the Intended Use section does not
qualify as appropriate.
The enclosed documentation is an integral part of this product. Keep the
documentation in a convenient place for future reference and observe all instructions
contained therein.
The type label must remain permanently attached to the product.
2.2 Safety precaution for Battery Pack
2.2.1 General safety precautions
Overvoltage or wrong wiring can damage the battery pack and cause deflagration, which
can be extremely dangerous.
All types of breakdown of the battery may lead to a leakage of electrolyte or
flammable gas.
Battery pack is not user serviceable. High voltage is present in the device.
Read the label with Warning Symbols and Precautions, which is on the right side of the
battery pack.
Do not connect any AC conductors or PV conductors which should be only connected to
the inverter directly to the battery pack.
Do not charge or discharge damaged battery.
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.

SAFETY
04
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 CO2 extinguisher 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.
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.
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.

WARNING
Risk of chemical burns from electrolyte or toxic gases
During normal operation, no electrolyte can leak from the battery pack and no
toxic gases can form. Despite careful construction, if the battery pack is
damaged or a fault occurs, it is possible that electrolyte may be leaked or toxic
gases formed.
Store the battery pack in a cool and dry place.
Do not drop the battery pack or damage it with sharp objects.
Only set the battery pack down on its back or its bottom, i.e., on the side with
the mounting lugs.
Do not open the battery pack.
Do not install or operate the battery pack in potentially explosive atmosphere
or areas of high humidity.
If moisture has penetrated the battery pack (e.g. due to a damaged
enclosure), do not install or operate the battery pack.
In case of contact with electrolyte, rinse the affected areas immediately with
water and consult a doctor without delay.
DANGER
Danger to life due to electric shock when touching live system components
in case of a ground fault.

STORAGE
04 Storage
4.1 Inverter Storage
The following requirements should be met if the inverter is not put into use directly:
1. Do not unpack the inverter.
2. Keep the storage temperature at -40~70°C and the humidity at 5%~95% RH.
3. The inverter should be stored in a clean and dry place and be protected from dust and
water vapor corrosion.
4. A maximum of six inverters can be stacked. To avoid personal injury or device damage,
stack inverters with caution to prevent them from falling over.
5. During the storage period, check the inverter periodically. (It is recommended that the
check is performed every three months.) Replace the packing materials that are damaged
by insects or rodents in a timely manner.
6. If the inverters have been stored for more than two years, it must be checked and
tested by professionals before being put into use.
4.2 Battery Storage
The following requirements should be met if the battery pack is not put into use directly:
1. Place batteries according to the signs on the packing case during storage. Do not put
batteries upside down or sidelong.
2. Stack battery packing cases by complying with the stacking requirements on the
external package.
3. Store the battery pack out of reach of children and animals.
4. Store the battery pack where it should be minimal dust and dirt in the area.
5. Handle batteries 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 batteries in a dry and clean place with proper ventilation.
– Place batteries in a place that is away from corrosive organic solvents and gases.
– Keep batteries away from direct sunlight.
– Keep batteries at least 2 m away from heat sources.
7. The batteries in storage must be disconnected from external devices. The indica-tors (if
any) on the batteries should be off.
8. Batteries should be delivered based on the "first in, first out" rule.
9. 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.
10. 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.

UNPACKING
