Industries and Applications We Power
Tiny homes & cabinsPurpose-sized for off-grid tiny homes, transportable homes (drawbar or gusset mount) and weekenders.
Off-grid homesComfortable 2-bedroom off-grid living; step up to the ‘EX’ or Mastiff for larger homes.
Eco-tourism & glampingSilent power for guest stays, with lockable guest-mode monitoring options.
Construction & miningRemote power stations for site facilities without fuel logistics.
Government & communitiesTen Blue Heeler units restored reliable power to the remote Langarra community in the NT – delivered under budget.
Read the case study.
Demountables & site officesClean power for accommodation and office buildings anywhere.
For Government, Councils and Large Organisations
Maxxiom supplies procurement-ready off-grid power to councils, government agencies, Tier 1 contractors and large operators. Every system arrives with the documentation your submission needs, and is designed, manufactured and supported from our own Brisbane facility – not imported and drop-shipped.
Modular means redundancyAt Langarra in the Northern Territory the client first specified one large centralised system. We proposed ten Blue Heeler units instead – no cranes or barges needed, delivered under budget, and if one unit is ever serviced the community keeps its power. A single centralised system is a single point of failure.
Australian made in BrisbaneDesigned and manufactured locally for Australian Industry Participation and supply-chain resilience. Support and spare parts come from our workshop, not an overseas importer.
Compliance documentedBuilt to AS/NZS 3000, 3001, 4509 and 5033 with CEC/SAA guidelines, delivered with engineering documentation, schematics and commissioning reports.
Fleet visibilityGPS locator and 4G monitoring on every unit – see where each system is and its state of charge before you dispatch a technician or a truck.
Fuel-free operating costNo fuel logistics, no refuelling labour, no noise complaints. On a comparable Maxxiom deployment fuel use fell 100% in the first six months, saving up to $136 a day and cutting 1.62 tonnes of CO2 a month.
Emergency & resilience readySilent, self-recharging power for the assets that must not go dark – evacuation centres, community halls, water pumping and remote facilities. A generator needs a fuel truck; this recharges itself from the sun every day.

Frequently Asked Questions
Is the Blue Heeler MK II big enough to run a tiny home?
Yes – it is designed exactly for that. The 5 kVA inverter comfortably runs lights, fridge, TV, laptops, water pump and washing machine, with 9 kWh of usable battery for overnight. For heavy air-conditioning or a larger home, consider the Blue Heeler ‘EX’ or Mastiff MK II.
How many solar panels does it need?
We recommend 12 x 440 W panels (about 5.2 kW) across its dual MPPT inputs. That is roughly 26 square metres of roof or ground-mount area, facing north to north-west for the best result.
What happens during long periods of bad weather?
The Blue Heeler includes a 15 A generator inlet with 2-wire auto-start. If the battery runs low during extended cloud, it starts your generator automatically, recharges, then shuts it off – you do not have to do anything.
How long does the battery last overnight?
With 9 kWh usable, typical overnight loads (fridge, lights, electronics at around 0.4 kW) run for well over a full night. At a constant 0.5 kVA draw the battery alone lasts about 18 hours; at 1.5 kVA about 6 hours.
Can I add more battery storage later?
Yes. The Blue Heeler MK II expands in 5 kWh steps up to 25 kWh using the ‘EX’ expansion unit, which also accepts an extra MPPT charge controller for more solar. Multiple Blue Heelers can also be paralleled together.
Is it really Australian made?
Yes – Maxxiom systems are designed and manufactured in Brisbane, Queensland, built on Victron power electronics and lithium battery modules, in a stainless steel cabinet made for Australian conditions.
Can it be installed outdoors?
Yes. The cabinet is IP55 rated with active controlled cooling, suitable for high-temperature locations – install it inside a garage or shed, or outside by the wall.
How do I monitor the system?
4G cellular remote monitoring is included for the first 12 months, so you can watch generation, usage and battery level from your phone anywhere. After that, renew the 4G plan, use your own Wi-Fi, or add the Peer-to-Peer Wireless Display for monitoring with no internet at all.
What warranty does it come with?
Five years on the power equipment and ten years on the battery. Maxxiom is an Australian manufacturer, so support and parts come from our Brisbane workshop, not an overseas importer.
What does installation involve?
The system arrives pre-assembled and factory-tested. A licensed electrician hard-wires it to your building’s distribution board and connects the solar array – typically well under a day on site. We can arrange full installation and commissioning in our service areas.
Do you supply to government, councils and large organisations?
Yes. Maxxiom delivers to councils, government agencies, Tier 1 contractors and large operators, with the documentation procurement needs: capability statement, quality management system, environmental statement, battery emergency response plan, SWMS and risk assessments, plus engineering documentation and commissioning reports. We hold Licensed Electrical Contracting in QLD, NSW and NT and carry Product, Public Liability and Professional Indemnity insurance. ABN 88 662 397 560.
Can you supply multiple units for a community or multi-site project?
Yes, and it is often the better engineering answer. For the Langarra community in the Northern Territory we supplied ten Blue Heeler MK II units instead of one large centralised system – which removed the need for cranes and barges, came in under budget, and means servicing one unit never takes the whole community offline. Each unit is GPS-tracked with 4G monitoring so a fleet can be managed remotely.
