KickAss 12V to 240V Pure Sine Wave 3000W Inverter

KickAss 12V to 240V Pure Sine Wave 3000W Inverter

The KickAss 12V to 240V Pure Sine Wave 3000W Inverter is a high-capacity power solution designed for larger off-grid setups such as caravans, motorhomes and work trailers. Built to run heavy-duty appliances like air conditioners, heaters, induction cooktops and everyday electronics, it delivers reliable household-style power wherever you travel.

Please note: the inverter does not include battery cables. Suitable cables must be purchased separately to ensure safe and correct installation.

Engineered for larger power systems, this inverter converts 12V DC battery power into stable 240V AC output, making it suitable for complete caravan electrical systems, motorhome installations and professional-grade off-grid setups. The pure sine wave output replicates standard mains electricity, ensuring safe operation for sensitive electronics such as laptops, CPAP machines, Starlink systems and entertainment devices.

An integrated automatic transfer switch (ATS) allows seamless switching between battery power and mains power. When mains power is available, the system automatically prioritises it, and instantly switches back to battery power during outages, ensuring uninterrupted operation. Safety is built into every layer of the system, with advanced multi-level protection including overload, over-voltage, over-current, short circuit and thermal protection, plus integrated residual current device (RCD) and circuit breaker (CB) hardware protection.
