How does an SPS work?

The main source of stand-alone power system (SPS) generation is renewable energy, such as solar panels. This power is used immediately by the customer and excess power is stored in the battery. The battery has significant capacity to cover a customer’s needs at night and during periods where generation is low (such as several cloudy days in a row).  The system is sized to match the power use of the property to ensure it is fit for purpose.

The job of the inverter is to convert the Direct Current (DC) power to Alternating Current (AC) power appropriate for home and business use. The back-up generator can supply full power requirements when the battery is low, while also charging the batteries when required.
