KickAss 12V 460Ah Ultra-X Deep Cycle Lithium Battery Bundle with 3000W Inverter, 50A Charger & 40A DCDC Charger - 460Ah Total Capacity

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

3000W Continuous Output

Plenty of power to run all your AC essentials while on the move—induction cooktops, coffee machines, battery chargers for your power tools, and more!

Pure Sine Waveform

Delivers a clean and reliable sine wave output that replicates the AC signal you get from a home power point. Unlike modified sine wave inverters that don't produce a true sine wave, the KickAss Pure Sine Wave Inverter is ideal for running sensitive electronic devices like laptops, Starlink, and CPAP machines.

AC Automatic Transfer Switch

Simplify your off-grid installation with the Automatic Transfer Switch. Power your AC devices from your batteries, then once you’re back on-grid, simply plug in the AC input cable to switch over to mains power. If the mains supply cuts out, the inverter will seamlessly switch back to battery power.

Multiple Protective Features

Multi-level safety protection utilises both software and hardware features to protect you, your inverter, and your devices. The inverter continuously monitors operation and will trigger protection mode if an unsafe condition is detected. Integrated Residual Current Devices (RCD) and Circuit Breakers (CB) provide additional hardware protection, making the inverter suitable for commercial environments.

Optional Remote Control Display (Not Included in Base Version)

The optional remote display allows you to monitor and manage power usage wherever needed. The low-profile screen is discreet and can be flush-mounted into any panel—for example, near your camp kitchen. The remote also features an integrated on/off switch to conserve battery power.

Note: Only compatible with the blue KickAss remote inverter screen.

Surge Power – Reaches 6000W in 2 Seconds

With a peak surge rating of 6000W for up to 2 seconds, this inverter is ideal for supporting devices with a high current draw, like power tool battery chargers, microwaves, and induction cooktops.

High 94% Conversion Efficiency

Inefficient inverters waste energy when converting DC to AC. The KickAss 3000W Pure Sine Wave Inverter achieves 94% efficiency, maximising the usable capacity of your battery bank.

Integrated USB Charging Ports

Includes an integrated 5V 2.1A USB port for convenient charging of your small devices directly from the inverter.

Smart Cooling System

The smart fans automatically adjust their speed to keep the inverter cool, increasing efficiency and maintaining optimal power output.

High Quality Circuitry Components

Built using premium quality components and the latest technology, this inverter delivers reliable performance. Even under heavy loads and peak surges up to 4000W, it remains protected against spikes and surges.

Multiple Mounting Options

Four convenient mounting points allow easy installation into your caravan, camper, or canopy 12V power setup.
