Fronius Symo Battery System

German inverter maker Fronius Gmbh have integrated their advanced 3-phase Symo hybrid inverters, with high performing L-ion Phosphate battery modules, to create the Fronius Energy Package. The 5kW hybrid inverter supports up to 12kWh of storage, and accommodates up to 8kW of solar PV. It even pairs with compatible existing solar inverters.

    Quality Components
    It’s unwise to make compromises when you are energy independent. There is a world of difference in the quality of system components, so we make sure we only source the very best.
    Expert Design
    Inferior off-grid systems provide frustratingly unreliable power and a costly short system life due to poor sizing, mismatched equipment, non-compliant design, and unsafe installation. Our expert technicians ensure these pitfalls are avoided.

    We have hundreds of happy battery storage customers across Australia. When you ask us for a customer reference, we can provide someone with an off-grid system just like yours.
    We understand the responsibility of providing reliable power, and being available 24/7 to troubleshoot. We value honesty and integrity in our staff, and always strive to exceed expectations.
