Maximum Capacity, Standard Or PRO
Both versions of this inverter deliver 3000W continuous and 6000W peak pure sine wave output, with under 3% total harmonic distortion and 89–92% efficiency. The 15A-rated Australian outlet covers the inverter's full output without needing to step down, while standard 10A appliance plugs still fit. At full 3000W load you'll draw roughly 260A from a 12.8V lithium battery, so plan for a substantial battery bank and heavy-gauge fused cabling. The PRO version adds a built-in automatic transfer switch for smooth switching between your primary power source and the inverter, plus an external residual current device (RCD) that instantly disconnects power during a fault. Both models are vibration-resistant, IP22 rated and built for the -10°C to 50°C range typical of Australian conditions.

Frequently Asked Questions
What's the difference between Standard and PRO?
Both deliver the same 3000W/6000W pure sine wave output. The PRO adds a built-in automatic transfer switch and external RCD for safer, smoother switching between power sources, and pairs with the RC3 PRO remote.
Does the Standard model come with a remote and cable bundle?
No, the Standard 3000W is sold as the inverter only, with the remote and fused cable available separately. The PRO offers a bundle option that includes both.
What size battery bank do I need?
At full 3000W output you'll draw around 260A from a 12.8V lithium battery, so you'll want a substantial battery bank and heavy-gauge fused cabling to match.
What cable should I use with the PRO bundle?
A 000AWG cable with a 450A fuse is recommended for this inverter, included in the PRO's Remote & Fused Inverter Cable option.
