AC Coupled
The Alpha SMILE 5 Solution can be connected without any solar PV present. This will ensure that the batteries remain charged from Eskom in case of unstable grid connection, or power outages. The system will use the battery to power the essential loads. Also, for Eskom “Time of Use” customers, the system can be set up to charge the batteries when the cost of electricity is low, and use them when charges are high.

DC Coupled
Power produced from Solar Modules installed on the roof are harnessed by the Alpha SMILE5 Inverter and used to charge the battery directly. Once the batteries are fully charged the power from the modules will be used to power the general loads and essential loads. Where the Solar module power is not sufficient the balance of the power will be drawn from the battery to make up the difference. Should the power from the Solar Modules and the battery not be enough the balance will then be drawn in from Eskom to service the loads.
In case of power outages the battery the SMILE5 will use power from the battery to power the essential load requirements.

The SMILE5 Solution can be added to any existing Solar PV system to function as a Back-up / UPS System. In this instance the Alpha SMILE5 Inverter will draw power from the existing Solar PV system to ensure that the batteries are fully charged. In case of power outages the Alpha SMILE5 will supply power from the batteries to the essential loads.
