How It Works
From Panels to Power Point
Your solar panels charge the battery through the day. The cabinet stores that energy and inverts it to standard 240 V power for the home, so lights, fridge, pumps and appliances run exactly as they would on the grid.
When you need more storage, the platform expands. When the weather turns, the battery carries you through. And you can watch all of it from your phone.
FAQs
Off-Grid Power for Tiny Homes, Answered
What size off-grid system does a tiny home need?
It depends on your appliances and how long you run them. A Kelpie MK II suits a cabin or one-bedroom home, and a Blue Heeler suits a two-bedroom home. Our sizing calculator gives an instant estimate.
Can an off-grid system run a fridge, lights and pumps?
Yes. Our systems deliver standard 240V power for lighting, refrigeration, devices, pumps and everyday appliances, day and night.
Is it silent?
Yes. Solar and battery power runs with no generator noise, no fumes and no refuelling, which is ideal for quiet off-grid living.
Can I expand the system later?
Yes. The platform is modular, so you can add battery, solar or inverter capacity as your needs grow.
Do you install for tiny homes?
Yes, across Queensland, New South Wales and the Northern Territory. Elsewhere in Australia we supply and support the system for your local installer.
What is the lifespan of the system?
Most of the critical equipment has a service life of around 15 years, enclosed in a stainless steel cabinet. With the modular design of our system these components are highly accessible and can be changed easily, extending the service life almost indefinitely.
How long can this system run my tiny home?
Run time is based on your power usage: the more energy-demanding appliances you use, the less time the system will run from the battery. During the day the system provides power from solar first and then from the battery; at night power comes only from the battery. If your usage is similar to 97% of tiny home owners with a Blue Heeler MK II, your battery will still be half full every morning at dawn, with overcast weather the exception.

Australian Operations
Designed, Built and Supported in Queensland
Maxxiom 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 can talk through your load profile rather than read from a script. We supply nationally and install across South East Queensland and regional Queensland.
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, 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 system in Brisbane and supply them Australia-wide for regional and remote projects. Our licensed electrical team delivers full installation and commissioning across Queensland, New South Wales and the Northern Territory, including remote and Indigenous communities. Elsewhere in Australia we supply and support your system for a local installer.
Are Maxxiom systems Australian made?
Yes. Every Maxxiom system is engineered and assembled at our Crestmead facility in Logan, south of Brisbane. That means local parts, local technicians, shorter lead times and Australian-made content for government and procurement requirements.
Will an off-grid system run everything I need?
Our range spans a 3kVA Kelpie for a shed or cabin right through to a 10kVA Mastiff and multi-cabinet builds for whole homes and communities. The right size depends on what you want to run and for how long, so we size each system to your actual load. Use our sizing calculator for a recommendation in about a minute, or ask us for a tailored assessment.
Do Maxxiom systems work with a generator?
They can. Our systems are designed to run fuel-free on solar and battery, but they integrate with a backup generator where a site needs one, with automatic start and stop. For construction and emergency use this gives you clean, silent power day to day and a fallback for extended low-sun periods.
What warranty comes with a Maxxiom system?
Our PowerBox range is backed by a 10-year battery warranty, with long-life LiFePO4 cells and remote monitoring so performance can be checked without a site visit. Full warranty terms are provided with every quote.
Can I expand the system later?
Yes. Maxxiom is a modular platform. Battery capacity, solar and inverter capacity can be added as your needs grow, and the Blue Heeler EX expansion cabinet takes a system up to 20kWh and beyond. You are not locked into today's requirement.
Do you supply government, councils and large organisations?
Yes, it is a core focus. We supply a capability statement and full documentation pack with every tender response: ISO-aligned processes, WHS-ready procedures, CE-certified components, insurances and compliance to AS/NZS standards. Our systems are already deployed with tier-one civil contractors and at major public events.
How much does an off-grid power system cost?
Every system is sized to the site, so we quote rather than list a price. Cost depends on your daily energy use, peak load, solar and battery capacity and whether installation is included. Request a quote and we will give you a clear, itemised figure.
What standards and compliance do your systems meet?
Maxxiom systems are built to the relevant 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.
