    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.
