Off-Grid Tiny House Basics (Australia): Power, Water, Waste
A practical off-grid starter guide for tiny houses in Australia: what to plan for with solar, batteries, water tanks, and waste systems.
Off-grid is a system, not a checkbox
Off-grid living works best when the build, appliances, and lifestyle are planned together.
Power (solar + batteries)
Key considerations:
- your daily energy use (fridge, hot water, cooking)
- winter sunlight where you'll park
- heating/cooling loads (often the biggest draw)
Water
Most off-grid setups use:
- rainwater collection + tanks
- filtration (for drinking water)
- a plan for drought periods
Waste
Options vary:
- composting toilets
- cassette toilets
- connection to septic/sewer where available
Builder questions
- Is off-grid wiring/plumbing included or an add-on?
- What's the recommended appliance package?
- What are the maintenance requirements?
Next step
Compare builders and ask specifically about off-grid packages:
Common off-grid mistake
Underestimating heating/cooling loads. A well-insulated build is an off-grid advantage.
FAQ
Can I run aircon off-grid?
Yes, but you need realistic solar + battery sizing.
Do off-grid packages increase build cost?
Usually, yes. But they can reduce site connection costs depending on the situation.
What's the best first step?
Work out your daily energy and water needs before locking in design.
