    Off-Grid System Range

    Shed Power

    The Shed Power systems are our smallest hardwired standalone power options. Designed for very small loads – such as a fridge, a TV, and a few lights – these systems are ideal for the man cave or the back shed

    Complete System

    The Complete System is the most versatile of our Standalone Power product range, capable of powering a broad range of medium to large properties.


    Off-Grid Systems

    Off-grid power systems supply electricity to properties that are not connected to the public electricity network. These systems are often referred to as “stand-alone power systems” (SAPS).

    The Off-Grid Energy Advantage

    Installing battery storage isn’t as simple as installing plain solar. Our head technician has been designing off-grid systems since 2002, and our core team has been working with battery systems since 2006.
    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.
    Happy Customers
    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.
    Endorsed, Certified & Awarded
    Our fantastic, hard working team has proudly received numerous awards, industry endorsements, and certifications from respected organisations.
