Why Off-Grid

One of the major benefits of a complete off-grid solution is lowered energy costs as utility companies normally have excessive grid connection charges for consumers who are in remote areas.


An off-grid solution is an ideal option for you if your building isn’t connected to an energy network. It’s also possible if you’re looking to disconnect from one. They’re ideal for work sites and remote locations, especially if you’re currently using diesel fuel to keep your business up and running. Some good reasons to install an off-grid solution are:

  • Reduction in diesel generation usage and costs
  • No expensive grid connection charges
  • Scalable up to 76 kW (IEC) or 61kW (UL)

We offer a full range of off-grid power systems from smaller houses to commercial and agricultural applications. Our company has a variety of solutions, for your off-grid or remote energy needs. Our off-grid systems are flexible and provide the ability to scale the system size in the future.

Frequently Asked Questions

  • What is the meaning of off grid solar system?

    Off-grid solar systems are not connected to the utility power grid, which means you'll be completely responsible for generating your own electricity using your solar panels. Unlike grid-tied systems, an off grid solar system requires battery storage solutions for it to work optimally. Off-grid solar systems are usually used by people who live in remote areas where the utility power grid isn't available, or by those who want to be completely independent from the electricity grid.

  • How does off-grid solar work?

    Solar panels are used to collect energy from the sun. This energy is then converted into electricity by a solar inverter. The electricity is used to power lights, appliances, and other devices in the home during the day. Any surplus electricity is stored in batteries for later use. When the sun is not shining, the batteries provide power to the home. If the batteries run low, a backup generator can be used to supplement the power supply.

  • Can you go off grid in Australia?

    Yes. It is completely legal to live off the grid in Australia, but there are certain conditions and limitations that you need to be aware of. For instance, each county and town might have their own different regulations, laws and permits when it comes to off-grid living. You need to check the local regulations first before carrying on with your plan to go off grid.

  • Is the solar battery rebate available for an off-grid system?

    Unfortunately, there are no rebates when getting a solar battery for an off grid system. The Victorian Government's rebates are only available for a solar battery system with a grid-tied inverter. But even without solar battery rebates, getting an off-grid solar system is absolutely worth it from a financial standpoint because it's the type of investment that will pay for itself many times over in the future.
