12V & 24V Pure Sine Wave Inverters in Perth

Every inverter we stock outputs pure sine wave — the same clean AC power your appliances get from a home power point. Modified sine is cheaper but runs hot into sensitive gear like CPAPs, induction cooktops, variable-speed tools and modern electronics. Pure sine is what the appliance was designed for, and it's what we fit.

Add up the continuous watts of everything you'll run at once, then add headroom for the biggest single motor or heating element (microwave, kettle, induction cooktop, air compressor). Most touring builds land at 1200–2000W. Permanent caravan or canopy installs usually want 2000–3000W. Full off-grid setups step up to 5–15kVA. Send us your appliance list if you want us to size it for you.

Redarc is our default recommendation for touring — Australian-designed, Australian-built, with a warranty we've never had trouble honouring. Victron suits integrated systems where you want full monitoring and multiple charging sources talking to each other, from the Phoenix compact range up to Quattro-II 48V. Enerdrive is well-priced and proven in caravans, with the 2000W ePower a long-running workshop favourite.

For canopy, caravan and shed builds, an inverter-charger like the Victron MultiPlus, MultiPlus-II or Quattro does inverter, battery charger and transfer switch in one unit. Plug into shore power and it charges the bank; unplug and it runs 240V loads off the batteries — automatically. Redarc's 3000W ATS+RCD unit does the same for permanent Australian installs.

A 3000W inverter at 12V pulls around 300A under full load — cable size, fuse selection and battery bank all have to keep up. We carry the cable, lugs, bus bars, fuses and remotes to go with every inverter on the page, and we can install the whole loop at our Bayswater workshop. Not sure your bank is up to it?
