The ultimate guide to off-grid living
What house-scale off-grid living actually runs on: a system sized for winter, storage that carries the quiet days, and a generator rule written before any brand is named.
Nevada Gigafactory, off the roof
Could you run Tesla’s Nevada Gigafactory off the roof? Reported rooftop solar, in home-system terms, and a teaching sketch for true off-grid car-building.
WA gold, engines off
Bellevue Gold ran four days with the diesel and gas engines switched off. Hybrid plant, two-hour battery, high-80% quarterly renewables.
Marlinja microgrid
A remote NT community built its own solar and battery and cut power bills by about 70%. Grid still there when the pack is empty.
Wilandra solar irrigation
A Gippsland dairy irrigated 22 hectares on about 95% solar, using a dam instead of a big battery.
SA commercial battery rebate examples
Design examples — not named customer case studies — for a cold store, workshop, irrigation shed and mining-adjacent depot. How the seventy-five thousand dollar ABN cap actually works.
Why commercial batteries can make sense in SA
Peak tariffs, fire-day backup, honest rebate stacking, and diesel hours. For Adelaide Hills, regional SA, and mining-adjacent businesses.
Dalby data centre, off-grid sizing
What would it take to run the Dalby data centre on sun and batteries? One stage of the build, in home solar and battery terms.
Electric UTVs in Australia
Voltage, solar charging with real numbers, onboard 240V, and AU-available machines for an off-grid or hybrid block.
Want a system sized that way?
If you want a plant sized for June and the rain week — home, farm, or commercial — talk to The Off Grid Shop.
