Power your property completely independent of the grid
Off Grid Power Co designs and installs complete off-grid solar, battery and standalone power systems for rural homes, acreage, cabins and sheds across the Sunshine Coast and South East Queensland — engineered around how you actually use power.
An off-grid system has to do everything the grid does — every day, without fail
There's no network to fall back on when a battery runs low or a heavy load kicks in. That makes standalone power a design discipline, not a product you buy off a shelf. We size every component to your property's real demand, build in the autonomy you need for bad weather, and integrate generator backup where it's warranted — so the system performs in July, not just in the brochure.
The problems that bring people off the grid
Going off-grid isn't always about being remote. Often it's a number on a quote, a recurring bill, or a system that already exists but no longer keeps up. If any of these sound familiar, a properly designed standalone system is worth costing out.
Talk through your situationThe grid connection quote is huge
Running poles and wire to a rural block can cost tens of thousands. Often a standalone system is the cheaper long-term answer.
There's no mains power at all
Acreage, bush blocks, sheds and cabins the network never reached. We build complete power independent of any connection.
Bills keep climbing
If you're already paying high supply charges and usage on a rural connection, off-grid can take you off the meter for good.
An existing off-grid system can't keep up
Ageing batteries, undersized solar or a system that drops out in winter. We assess, repair and right-size what you've got.
Off-grid power, end to end
From full off-grid homes to shed and cabin power, design through to install, repairs and upgrades.

Learn moreDesign first, then build
Every reliable off-grid system starts with honest numbers. Here's how we work.
Load assessment
We start with how you actually use power — appliances, pumps, AC, peak demand and the days of autonomy you want. No guesswork, no packaged products.
System design
We model battery autonomy and size solar, storage and inverter capacity to match your loads — then integrate generator backup where the numbers call for it.
Clear proposal
You get a written proposal that explains the system, the equipment and the reasoning. Indicative, honest, and tailored — never a fixed package quoted sight-unseen.
Licensed install
Installed and commissioned by a licensed Queensland electrical contractor to the relevant Australian Standards, then handed over with the support to keep it running.
Specialists in standalone power
Off-grid is unforgiving of shortcuts. We focus on it exclusively, design around your real loads, and back our work with the licensing and compliance a remote power system deserves.
See how we design systemsOff-grid is all we do
We're not a grid-tie installer dabbling in batteries. Standalone power is our specialty — the design discipline it demands is what we do every day.
Designed around your loads
Every system is sized from your real energy use and the autonomy you want, so it performs in the worst weather, not just on a sunny brochure day.
Licensed & compliant
Licensed Queensland electrical contractor, installed to Australian Standards. Safe, compliant, and built to last on remote and rural properties.
Straight advice
We'll tell you honestly whether off-grid stacks up against a grid connection for your block, and won't sell you capacity you don't need.
A serious investment — engineered to last
A complete off-grid system is a considered investment, not an off-the-shelf product. The right figure depends on your daily energy use, the days of autonomy you want and the equipment your site calls for. We don't quote cheap packages sight-unseen — we design to your loads and give you a clear, written proposal so you know exactly what you're paying for and why.
Sized to your loads
Costed from real energy use and autonomy — never a generic package.
Quality components
Reputable inverters, batteries and solar selected to last in remote conditions.
Transparent proposal
A written breakdown of the system, equipment and reasoning before you commit.

Frequently Asked Questions
How much does an off-grid solar system cost in Queensland?
Off-grid systems vary widely because they're engineered around your actual loads. A simple shed or cabin system is relatively modest, while a full-home off-grid system with generator backup is a far larger investment. Cost is driven by daily energy use, battery capacity, inverter size, generator integration, switchboard work and installation access. We assess your real loads before recommending a system and provide a clear written proposal — we never quote a fixed package sight-unseen.
Can I run air conditioning off-grid?
Yes, but it has to be designed in. Air conditioning is a heavy, surging load, so the inverter must handle the start-up surge and the battery must carry the runtime. We size the system around how and when you actually run AC. Inverter-style (soft-start) units are far easier to run off-grid than older fixed-speed units.
Do I need a generator with off-grid solar?
Most reliable full-home off-grid systems include a generator for backup. Solar and batteries handle the vast majority of the year, but a generator covers extended overcast periods, unusually high demand or maintenance windows. For smaller shed and cabin systems a generator is often optional. We'll tell you honestly whether your situation warrants one.
How many batteries do I need for an off-grid home?
It depends on your overnight consumption and how many days of autonomy you want during poor weather. Rather than guess, we model your daily energy use and the bad-weather reserve you need, then size the battery bank to suit. Undersizing leads to flat batteries and generator overuse; oversizing wastes money — proper sizing is the whole point.
Can off-grid solar power a full house?
Yes. A correctly engineered off-grid system can run a full home including fridges, lighting, pumps, hot water, Starlink and air conditioning. The key is honest load assessment and sizing the solar, battery and inverter capacity to match — and including generator backup where the numbers call for it.
Is off-grid cheaper than connecting to the grid?
Sometimes. On rural and acreage blocks where the power authority quotes tens of thousands of dollars to run a line in, a stand-alone power system can be the more sensible long-term investment. On a block already close to the grid it usually isn't. We'll give you a straight answer based on your grid-connection quote and energy needs.
Can you upgrade an existing off-grid system?
Yes. We regularly upgrade tired or undersized systems — adding battery capacity, replacing failed batteries with modern lithium, upgrading inverters, or integrating a generator. We start by assessing what you have and where it's falling short before recommending the most cost-effective upgrade path.
Do you install off-grid systems for sheds and cabins?
Absolutely. Sheds, workshops, cabins, tiny homes and weekenders are a core part of what we do. These systems can be beautifully simple when scoped correctly — enough power for lights, fridge, tools, pumps and devices without paying for full-home capacity you don't need.
Do you service rural properties?
Yes — rural and acreage properties across the Sunshine Coast, hinterland, Gympie, Moreton Bay and wider South East Queensland are our specialty. We're used to long driveways, distant sheds, pump runs and properties the grid never reached.
What happens during bad weather?
A well-designed system carries reserve capacity for several days of poor sun, and a generator (where fitted) covers anything beyond that. The autonomy figure is a design decision we make with you up front — how many low-sun days you want to ride through before the generator or load management kicks in.
