Power inverters in Australia: sizes, prices and warranties

Updated 4 November 2026

In Australia a 150 W inverter that runs from a 12 V car socket costs about A$40 to A$63, and a 2000 W pure sine wave unit about A$199 to A$500. Describe what you need to run in a request on BlaBlaPrice. The AI asks about power and battery, then shows the prices and businesses it finds.

Warranty and standards

Under Australian Consumer Law, a portable inverter must be of acceptable quality, so a faulty unit can be repaired or replaced. Warranty terms differ widely, so get the length in writing before you buy. If you plan to connect the unit to a home solar system, Western Australia's rules point to AS/NZS 4777.2 for inverter energy systems, and the Clean Energy Council's Products program says approved devices must meet Australian and international standards.

Summer and winter use

Summer runs from December to February, and winter from June to August. Summer is when fans, fridges and camp power are used most, so buy before December if you plan to use the unit then. A 2000 W unit draws heavily from the battery, so check the battery capacity before winter trips, when nights are longer.

How inverters are sold and sent here

Listings here quote 12 V DC to 230 V AC with an Australian plug. Check your battery voltage before buying, because a 24 V battery needs a unit built for it. Power is rated in watts, so add up the devices you plan to run. Prices are for the unit alone, so ask whether delivery to Sydney, Melbourne, Brisbane, Perth or Adelaide is included.

What to write in your request

Say what you want to run, such as a laptop, a fridge or power tools, and for how long. Give the battery voltage, the continuous power in watts, whether you need a pure or modified sine wave, and whether you want new or used. Add your city, your budget and the warranty length you want. The right size depends mostly on what is connected.
