    How the sonnenBatterie works to save you money

    Store energy while the sun is shining and use it day or night – never worry about the lights going out.

    The sonnenBatterie is a hi-tech solar battery storage system that has proven itself in thousands of households every day, outperforming other batteries in its class. Made in Germany, this durable, intelligent energy manager meets high standards of safety and quality.

    Aus Made  Australian made, German design.

    sonnen is the European market leader with more than 40,000 batteries now in homes across Europe and the world. Now, with the opening of Australia’s first sonnen manufacturing plant here in South Australia, sonnen’s innovative energy storage technology is readily available locally.

    Better managed energy use for bigger savings.

    sonnen’s intelligent Active Energy Manager learns how you use energy across the day and night to optimise your consumption. Depending on the weather forecast, time of day and your use, it automatically switches between solar, battery-stored and grid energy to power your home with the cheapest available source. The battery also recharges across the day, leaving you with plenty for the evening when retail prices are highest.
