Fully Off-Grid in Moore, QLD: A 6.6 kW AC Coupled Solar System Powering a Medium-Sized Home
Moore is a small community in the Somerset Region of Southeast Queensland, surrounded by the kind of rural landscape where grid connection isn’t always straightforward or affordable. It’s also the location of one of our recent stand-alone power system installations — a fully off-grid AC coupled solar setup designed specifically for a medium-sized family home, with the performance and storage capacity to run everything a modern household demands.
The Moore Off-Grid Solar System: Specifications
This stand-alone power system was custom-designed and installed by Stand Alone Power Systems, featuring:
Solar Array: 6 kW of high-efficiency solar panels
Solar Inverter: Fronius Gen24 5 kW inverter
Inverter/Charger: 10 kW Victron inverter-charger
Battery Storage: 18 kWh ecoPowerPlus Australian-made lithium batteries (CEC listed)
System Type: Fully off-grid AC coupled stand-alone power system
This is a system sized for real life — not a scaled-down compromise, but a genuine whole-home solution. Air conditioning, refrigeration, washing machines, entertainment systems, home office equipment — all of it, running entirely on sunshine and stored energy.
AC Coupled Architecture: The Smart Way to Design Off-Grid
This Moore system is built on an AC coupled architecture — a design approach that pairs a dedicated solar inverter with a separate inverter-charger to create a highly efficient and flexible off-grid power system. In simple terms, the Fronius Gen24 5 kW inverter converts the solar array’s DC output into AC power, which is then used directly by the household or fed into the Victron inverter-charger to charge the battery bank. The two inverters work in harmony, each doing what it does best.
AC coupling offers real advantages for a medium-sized home. The solar energy harvested by the Fronius inverter is available to power household loads directly and simultaneously, reducing the load on the battery bank during daylight hours and maximising the efficiency of every kilowatt the array generates. It’s a sophisticated approach to off-grid system design — and one that delivers measurably better performance in real-world conditions.
Fronius Gen24 5 kW Inverter: Exceptional Solar Performance
The Fronius Gen24 is one of the most respected solar inverters on the Australian market, and for good reason. Fronius has built a global reputation over decades for engineering quality, reliability, and innovation — and the Gen24 represents the very best of that heritage. Its ability to operate in off-grid and AC coupled configurations makes it an excellent choice for stand-alone power system applications, where reliability is non-negotiable.
In this Moore installation, the Fronius Gen24 manages the 6.6 kW solar array with precision — maximising energy harvest across the day and integrating seamlessly with the Victron inverter-charger to keep the ecoPowerPlus battery bank optimally charged. The result is a system that extracts the maximum possible value from every hour of Queensland sunshine, translating it into reliable, usable power for the household. If you want a solar inverter that simply performs, day in and day out, the Fronius Gen24 is extremely hard to look past.
The 10 kW Victron Inverter-Charger: Intelligent Power Management
The Victron inverter-charger is the intelligent nerve centre of this system — and at 10 kW, it’s sized to handle the full demands of a busy family home without breaking a sweat. When an air conditioner kicks on, when the electric oven and the kettle are running simultaneously, when the washing machine hits its spin cycle — the Victron absorbs those surge loads without missing a beat.
Victron’s inverter-chargers are trusted by off-grid installers across Australia and around the world for their exceptional build quality and genuinely intelligent energy management. Working in tandem with the Fronius Gen24 in this AC coupled setup, the Victron manages battery charging, load distribution, and grid-off operation with an elegance that makes the whole system feel effortless.
Remote monitoring via the Victron platform means our team can diagnose and resolve most issues remotely — minimising any disruption to the household.
18 kWh ecoPowerPlus Lithium Batteries: Australian-Made, Built to Last
Battery storage is where an off-grid system either delivers or disappoints — and the ecoPowerPlus batteries fitted to this Moore system are something genuinely worth talking about. These are Australian-made lithium batteries, designed and built locally to meet the specific demands of the Australian off-grid market. In a sector where much of the hardware is imported, that matters.
The ecoPowerPlus system delivers higher capacity storage in a compact rack mount design. Each unit provides 4.7 kWh in a 2RU form factor — meaning serious energy storage in a remarkably small footprint. For installers and homeowners alike, this compact design simplifies system installation, makes upgrades straightforward, and keeps equipment rooms tidy and manageable. The rack mount configuration also supports scalable energy storage across residential, commercial, and off-grid applications, making it equally at home in a family home in Moore as it would be in a commercial off-grid facility.
The ecoPowerPlus batteries are CEC listed — an important certification that confirms the product meets the Clean Energy Council’s standards for use in Australian solar and battery installations. It’s the mark of a product that has been independently assessed and approved for the Australian market, and it provides homeowners with confidence that what’s installed in their system is the real deal.
Built on lithium iron phosphate (LiFePO4) chemistry, the ecoPowerPlus batteries offer a long service life, high depth of discharge capability, and a built-in battery management system (BMS) that monitors and protects every cell. Unlike lead-acid batteries, there’s no maintenance schedule, no water topping, no degradation from regular deep cycling — just reliable, long-term performance. And because the system is fully modular and expandable, additional battery units can be added as energy needs grow, without replacing the existing bank. It’s a future-proof investment built for the long haul.
Why Off-Grid Makes Sense in Moore and the Somerset Region
Moore sits in Queensland’s Somerset Region, roughly an hour northwest of Brisbane. Properties here often have significant grid connection distances, and the cost of extending the network to a rural block can easily reach tens of thousands of dollars — before you’ve paid for a single unit of electricity. Meanwhile, the Somerset Region enjoys excellent solar irradiance year-round. The sun that makes summers here long and hot is the same sun that keeps a well-designed off-grid system running at its peak.
For this Moore homeowner, the economics were clear: the cost of a quality stand-alone power system compared favourably to the alternative grid connection cost — and unlike a grid connection fee, the solar system generates free energy from the moment it’s switched on, year after year.
Completely Grid-Off — and Not Missing It for a Second
This family has disconnected from the grid entirely. They run their home exactly as they did before — air conditioning in summer, full kitchen appliances, hot water, entertainment, everything. Their power bill is zero. Their connection fee is zero. And their energy independence is complete. A well-designed off-grid solar system should be invisible in operation: you flip a switch, and the lights come on. That’s the standard we design to, and it’s the standard this Moore family lives by every single day.
