SAFETY
Warning:
Risks of chemical burn electrolyte or toxic gases.
The battery modules installed in the BESS are protected by multiple
Electrical protection devices and can be operated safely during standard
operation. However, there is a potential for the electrolyte leakage from the
battery pack as well as form toxic gases if damaged mechanically or break
down. Therefore, it’s recommended to proceed as follows,
• Do not install the system in extreme low/high temperatures or humidity
exceeding the permitted range.
• Do not place heavy objects on top of the system or mechanically damage the
batteries (by piercing, puncturing or deforming it)
• Do not short circuit the battery module or allow them to come in contact with
metal.
• Do not continue to use the battery module after a short-circuit.
• Do not install the battery pack in the vicinity of any equipment containing
ammablegasesorliquids.
• If the moisture penetrates the system (e.g. due to casing damage), please
do not operate the system and contact Alpha ESS immediately for further
troubleshooting.
• If you come into contact with the electrolyte, please wash affected area with
water immediately, and consult a doctor immediately.
Risk of injury by hoisting or falling system
• Inverters and batteries are heavy and can cause personal injury if the inverter
or battery is improperly lifted or dropped during transport or when attached or
removed from walls.
• Lifting and transporting of SMILE-B3-PLUS/SMILE-BAT-5P must be conducted
by more than 1 person.

SMILE B3 PLUS
4. Smile B3 Plus
The SMILE B3 PLUS is a modular battery solution intended for residential solar
storage and is capable of being expanded from 5.04 kWh to 30.24 kWh. It has an
all-in-one design that’s pre-engineered to minimise installation time and ensure
ease of interaction, stability, and safety.
It is an AC coupled battery energy storage system (BESS) designed to achieve
optimal usage of solar energy while balancing offsets from the electricity grid.
It utilises excess solar (PV) generation to intelligently charge & discharge the
battery, and can operate under automatic, manual and time-of-use (ToU) modes.
In automatic mode, the SMILE B3 PLUS will store surplus energy in its batteries
and discharge towards house loads averting energy consumption from the grid. It’s
equipped with LED state indicators that capture a wide array of system functions.
Inaddition,thesystemallowstheend-userexibilitytoaddonmorecapacity
based on their energy requirements. The simple plug-and-play installation allows
the installer to connect the additional storage units in quick succession & reduce
overall time spent on-site.
The SMILE B3 PLUS use the safest battery chemistry available on the market –
Lithium Iron Phosphate (LFP). As an additional safeguard, software integration is
used to monitor and protect the battery from any potential damage.
The SMILE B3 PLUS has two separate components,
• Primary Unit (SMILE-B3-PLUS) – Battery pack with an Integrated Inverter.
• Secondary Unit (SMILE-BAT-5P) – Battery pack only (optional)

4.2 Operating Priciple
The system is designed to operate based on the data measured by the Grid & PV
CTs. The former constantly measures the Electricity consumption of the house and
the latter measures the power generated by the Solar PV system.
When the Solar production > House Loads, the surplus power is stored within the
batteries. When the batteries reach their peak capacity, the surplus is exported to
the Utility grid. For e.g, if Solar production is 5 kW and the house loads are 3.5 kW,
then the battery is charged at 1.5 kW.
When the House Loads > Solar Production, the battery discharges to cover the
decitbetweenthetwo.Fore.g,WhentheSolarProductionis3kWandtheHouse
loads are 4 kW, then the Battery will discharge 1 kW.
4.3 System Operation
The system must be turned On/Off in the correct sequence to avoid any damage.
Switching on
• Turn on the Main Switch Energy Storage (Battery) within the switchboard.
• Turn on the Solar PV Inverter Main Switch within the switchboard.
• If AC Isolator is connected on Grid side, turn it on.
• Short press the Power button on the right side of the Primary Unit, then switch
on the battery breaker until the normal LED turns on.
• Turn on the Battery Isolator located on the left-hand side of the Primary unit.
• Wait around 3 mins for the Primary unit to begin normal operation and observe
the LED states on the front panel (“Normal”, “COM” must be green)
• If a Secondary Unit is/are installed, short press the Power button on all
Secondary Units until the LED indicators light up.
Note - If Backup Loads are connected, Switch on the Backup Main Switch and any
connected RCBOs (UPS – dedicated circuits) within the Switchboard.
SMILE B3 PLUS

Owner’s Manual15
Switching Off
• Note – If Backup Loads are connected, Switch off the Backup Main Switch and
any connected RCBOs (UPS - dedicated circuits) within the Switchboard.
• Long press the Power button (6s) on the Primary Unit until the battery LED light
turns off.
• Turn off the Battery Isolator located on the left-hand side of the Primary Unit.
• If a Secondary Unit is/are installed, long press the Power button on all
Secondary Units until the LED indicators turn off.
• Turn off any AC Isolators located on either the Grid or Backup side.
• Turn off the Main Switch Energy Storage (Battery) within the switchboard.
4.4 System Operating Status

Error Codes
5.1 Function Checks
It’s recommended to periodically check if the system is operating correctly, and
ensure that it hasn’t gone into fault mode. In addition, end users are encouraged to
get an understanding of the operating principle, enery behaviour patterns (whether
battery charges to 100% daily, extent of discharge overnight, house loads etc) to
ensure your monitoring data aligns with your actual energy usage. If any unusual
behaviour does occur, contact your system provider or manufacturer for further
support.
5.2 System Faults/Errors
The Battery alerts the user to operational status using a wide range of Error &
Protection codes (as described below). Please note that the system is capable of
self/remote diagnosis whilst operating in Protection mode and is expected to return
to normal operation thereafter. Please contact your system provider or Alpha ESS if
the protection code persists for an extended period.
If the system displays an Error Code (as shown below), please contact your installer
or system provider urgently for further resolution. Do not attempt to resolve the
error by yourself or with the help of an unauthorised (non-Alpha ESS) technician, as
this may void the Warranty of the product.
