SMILE B3 PLUS

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
deficit 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.
