2. Safety
2.1. Intended Use
The inverter, battery packs and the energy meters make up a system for optimization
of self-consumption for a household. The inverter is equipped with two MPP trackers
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 of the energy.
The product is suitable for indoor and outdoor installation.
SMILE-S5 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 operate in a scenario suitable for their operation.
Be sure to use this product only in accordance with the information provided in the
enclosed documentation and with locally applicable standards and directives. Any
other operation 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 Instructions 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.
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 the user happens to be exposed to internal materials of battery cell due to
damage on the outer casing the following actions are recommended.
1. Inhalation: Leave the contaminated area immediately and seek medical attention.
2. Eye contact: Rinse eyes with running water for 15 minutes and seek medical
attention.
3. Contact with skin: Wash the contacted area with soap thoroughly and seek medical
attention.
4. 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
1. Respirator is not required during normal operations.
2. Use FM-200 or CO² extinguisher for battery fire.
3. Use an ABC fire extinguisher, if the fire is not from battery and not spread to it yet.

Safety
12
•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
1. On land: Place damaged battery into a segregated place and call local fire
department or service engineer.
2. In water: Stay out of the water and don't touch anything if any part of the battery,
inverter, or wiring is submerged.
3. Do not use submerged battery again and contact the service engineer.
2.3. Important Safety Instructions
Danger to life due to electric shock when live components or cables are
touched.
High voltage are present in the conductive components or cables of the product.
Touching live parts and cables results in death or leth
al injuries due to electric
shock.
•Do not touch non-insulated parts or cables.
•Disconnect the product from voltage sources and make sure it cannot be
reconnected before working on the inverter or the battery pack.
•After disconnection, wait for 5 minutes until the capacitors have discharged.
•Do not open the product
•
Wear suitable personal protective equipment for all work on the product.
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.

Safety
13
Risk of chemical burns from electrolyte or toxic gases.
During normal operation, no electrolyte can leak from the b
attery 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 may
form.
•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.
•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 housing),
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.
Risk of burns due to hot heatsink and housing.
The heatsink and housing can get hot during operation.
During operation, do not touch any parts other than the cover of the inverter.
Damage to the inverter due to electrostatic discharge.
•Touching electronic components can cause damage to or destroy the inverter
through electrostatic discharge.
•Ground yourself before touching any component.
Damage due to cleaning agents.
•The use of cleaning agents may cause damage to the product and its
components.
•Clean the product and all its components only with a cloth moistened with
clear water.

Safety
14
Danger to life due to electric shock when live components or DC cables are
touched.
When exposed to sunlight, the PV array generates high DC voltage which presents
in the DC conductors. Touching the live DC cables can result in death or lethal
injuries due to electric shock.
•Disconnect the inverter from voltage sources and make sure it cannot be
reconnected before working on the device.
•Do not touch non-insulated parts or cables.
•Do not disconnect the DC connectors under load.
•Wear suitable personal protective equipment for all work on the inverter.
Danger to life due to electric shock from touching an ungrounded PV module
or array frame.
•Touching ungrounded PV modules or array frames can result in death or lethal
injuries due to electric shock.
•Connect and ground the frame of the PV modules, the array frame and the
electrically conductive surfaces so that there is continuous conduction.
•Observe the applicable local regulations.
Danger to life due to electric shock when touching live system components in
case of a ground fault.
If a ground fault occurs, parts of the system may still be live. Touching live parts
and cables can result in death or lethal injuries due to electric shock.
•Disconnect the product from voltage sources and make sure it cannot be
reconnected before working on the device.
•Touch the cables of the PV array on the insulation only.
•Do not touch any parts of the substructure or frame of the PV array.
•Do not connect PV strings with ground faults to the inverter.
