Local Off-Grid Solar and Battery, Done Properly
Far North Queensland means heat, humidity and cyclones, so Cairns systems are built sealed and rugged, with solar that refuels itself when the grid goes down.
From a single off-grid cabin to a whole property, Maxxiom supplies and installs solar-battery power systems in Cairns and surrounding areas including the Atherton Tablelands, Port Douglas and Innisfail. We handle the load calculation, system design, supply, licensed installation and long-term support, so your off-grid power in Cairns simply works.
- Off-grid solar and battery systems for Cairns homes and tiny homes
- Transportable and event power for Cairns business and construction
- Generator replacement and fuel-free backup power
- Solar power for rural and remote properties around Cairns

Australian Operations
Designed, Built and Supported in Queensland
Our off-grid systems are engineered and assembled at our Crestmead facility, south of Brisbane, and supported by our own technicians.
That means shorter lead times, parts held locally, and an engineer who talks through your load profile rather than reading from a script. We supply nationally and install across Queensland, New South Wales and the Northern Territory, including Cairns.
What our customers say
Real Systems, Powering Real Off-Grid Homes
Amazing, reliable system. Remote access gives you peace of mind and confidence. The additional support and guidance from Maxxiom’s staff is outstanding, and the installation crew were absolutely professional, informative and friendly. After receiving several quotes and comparisons from other companies, I am glad I chose Maxxiom and highly recommend them to others.
Blue Heeler MK II ‘EX’ on an expandable home
I’m really happy with my Maxxiom system. It’s more than adequate and I enjoy using the app to see and plan my power usage. I’m also very grateful to Maxxiom for answering the hundreds of questions I had, and for explaining everything in a way I can understand. The install went really smoothly.

Questions & Answers
Off-Grid Power in Cairns, Answered
The questions we hear most from homeowners, builders, councils and contractors. Not sure about something else? Get in touch.
Where does Maxxiom deliver and install off-grid power systems?
We design and build every off-grid power system in Brisbane and supply Australia-wide, including Cairns. Our licensed electrical team installs and commissions systems across Queensland, New South Wales and the Northern Territory, including remote and Indigenous communities. Beyond those states we supply and support the system for your local installer.
Are Maxxiom systems Australian made?
Yes. Every off-grid system is engineered and assembled at our Crestmead facility in Logan, just south of Brisbane. That means local parts, local technicians, shorter lead times and genuine Australian-made content for government and procurement requirements.
Will an off-grid system run everything I need?
It can. The range runs from a 3 kVA Kelpie for a shed or cabin up to a 10 kVA Mastiff and multi-cabinet builds for whole homes and communities. We size each off-grid system to your actual load, so try the sizing calculator for a recommendation in about a minute, or ask us for a tailored assessment for your Cairns property.
Do Maxxiom systems work with a generator?
They can. Our off-grid solar and battery systems run fuel-free by design, but integrate with a backup generator where a site needs one, using automatic start and stop. For construction and emergency work that means clean, silent power day to day and a fallback for extended low-sun spells.
What warranty comes with a Maxxiom system?
The PowerBox range carries a 10-year battery warranty, with long-life lithium (LiFePO4) cells and remote monitoring so performance can be checked without a site visit. Full warranty terms come with every quote.
Can I expand the system later?
Yes. Maxxiom is a modular off-grid platform, so battery, solar and inverter capacity can be added as your needs grow. The Blue Heeler EX expansion cabinet takes a system to 20kWh and beyond, so you are never locked into today’s requirement.
Do you supply government, councils and large organisations?
Yes, it is a core focus. Every tender response comes with a capability statement and full documentation pack: ISO-aligned processes, WHS-ready procedures, CE-certified components, insurances and compliance to AS/NZS standards. Our off-grid systems are already deployed with tier-one civil contractors and at major public events.
How much does an off-grid power system cost?
Every off-grid system is sized to the site, so we quote rather than list a fixed price. Cost depends on your daily energy use, peak load, solar and battery capacity, and whether Cairns installation is included. Request a quote and we will provide a clear, itemised figure.
What standards and compliance do your systems meet?
Our systems are built to the Australian standards for stand-alone power, including AS/NZS 3000, 3001, 4509 and 5033, using Victron power electronics and lithium battery technology. Documentation is supplied for certification, procurement and handover.
