What is a power inverter? A power inverter is a device that converts battery output (DC, or direct current) into 230V AC mains electricity (alternating current). 230V AC is the type of electricity supplied by utility companies to run standard domestic appliances such as a TV, fridge, radio, lights, or to charge a laptop / mobile phone, etc. If you have a battery, connecting a power inverter will enable you to power household appliances in areas with no access to mains electricity, such as in a motorhome, caravan, boat, farm, or any other remote location. Inverters are also perfect for off-grid and backup systems for accidental power cuts.

This is a 4000W 12V pure sine wave power inverter which can generate 4000W of continuous power and up to 8000W of power at peak times (peak time reserve capacity is useful if more energy is required to start an appliance than for its continuous running).

This is a pure sine wave type of inverter, which means that the 230V AC output harmonically follows a smooth sine wave and is almost identical to normal mains electricity. Pure sine wave output is far superior to square sine wave or modified sine wave output for running appliances. This is because:

- It is suitable for a broader range of appliances (for example, appliances with electric motors cannot be powered by modified sine wave inverters)

- It is more efficient compared to modified sine wave inverters.

This product comes with important protection and safety features such as over-discharge, overload, overheating, and short-circuit automatic shutdown. The inverter also features a powerful USB port for faster charging of mobile phones, MP3 players, and other USB-compatible devices (2.1A). This item is also supplied with a remote on/off switch with 5m cable, to allow remote monitoring and powering of the inverter.

This product is covered by a 1-year warranty. For more information, please refer to our Terms and Conditions. This product comes with a user manual which explains wiring and operations (see Documents tab).

An adapter may be used for more sockets, provided that the total power consumption of all appliances connected to this inverter is within 4000W.

Note for users of our solar charging systems: this inverter can be connected to your 12V battery / battery bank alongside any of our solar systems or charging kits. If you already have one of our 12V solar charging kits with a charge controller connected to your 12V battery, you can simply add this inverter to your existing system (connect the inverter to your battery in parallel with the solar controller and 12V appliances). If the solar charge controller has a pair of "load" terminals, please do not connect the inverter to this pair of terminals as the power may be too high for the solar controller. We recommend connecting it to your 12V battery directly.
