securing your power and your future

Off-Grid Power – Complete System

The Complete Off-Grid Power System is the most versatile of our off-grid power products.

Its capabilities range from powering a medium sized house up to larger properties including;

  • Homes
  • Farms
  • Stations
  • Small Businesses

Functional & Compact Power

Each system we install is specifically designed to meet your property’s power needs, whether it be single phase or 3 phase. The system requires a small amount of space and will fit neatly in a utility shed, or alternatively in our weather proof and fully self-contained enclosure. Solar panels have the option to be mounted on your roof or on adjustable ground frames.

Off-Grid Power That Can Adapt To Your Needs

Different stages of your life or business demand different power needs, so we’ve designed the complete system with the ability to grow or reduce. We can simply add or remove any combination of solar panels, wind turbines, micro-hydro turbines or fuel generators to achieve your ideal power supply at every stage.

Its versatility is why the complete system is our most popular choice for off-grid power supply.

Grid Connection vs. Off-Grid Power

Determining the cost to connect your house to the electricity grid is an important first step when trying to consider whether to live on or off-grid. It is not uncommon for a quote to connect to mains power to be in the tens or hundreds of thousands of dollars. This can make an off-grid power system a much more affordable option upfront and of course, long term.

Off-Grid Energy Australia can assist you in obtaining an accurate cost of connection with the electricity distributor for your area. Just contact our friendly team.

Further Cost Considerations

Federal government rebates exist for eligible applicants, ranging from $1,700 – $30,000 depending on how much renewable energy is included in the final system.

Renewable Energy Fraction
Maximising your renewable energy sources will minimise ongoing generator costs.

Equipment Placement
For sites that do not have a suitable enclosure to house our AdaptUnit then the EnergyBox might be required at an additional cost.

Off-Grid Power System Load Profile

To accurately design your ideal system and provide you with a quote, we need to understand your property’s power usage.

We do this by asking you to complete an Energy Load Profile in which you list all the appliances and utilities that use power with an estimate of their usage amount. Once this is completed, we can recommend the best system design and size for you.

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

Essential power systems

Essential Systems

Ideal for low-consumption users, the Essential System offers a perfect green solution for your holiday retreat without the ongoing commitment and cost of grid connection.


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.
