4000W 24V PURE SINE WAVE POWER INVERTER 230V AC OUTPUT (UK SOCKETS), WITH REMOTE ON/OFF SWITCH

What is a power inverter? 

A power inverter is a device which 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 back up systems for accidental power cuts.

This is a 4000W 24V 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 than 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 can not 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.

Which appliances can be powered?

If you are unsure whether 4000W is sufficient for your appliances, please refer to the following table:

*Appliances marked with a star are likely to have a starting power consumption several times greater than their normal working power (typically this is caused by electric motors). This should be taken into account when choosing the correct size of inverter. For example, even though electric lawn mowers have a normal working power of 1000W, their starting power is over 4000W. This means that an inverter with a continuous power of 2000W is not suitable, because its peak power is limited to only 4000W. Always take into account the starting power requirements of your equipment - especially devices with electric motors - when choosing the right inverter.

**These appliances do not have an electric motor inside, but still have a variable power consumption with power spikes. Therefore they require a larger inverter than would be needed for other appliances with a similar nominal power rating.

Please also note: this table is provided for general guidance only. The actual power consumption of your appliances, as well as starting power requirements, may vary considerably. In all cases you will need to check the specifications of your equipment to find their continuous and starting power requirements.

If more than one device is connected to the inverter, the total power consumption should be the sum of all appliances used. This will determine the total inverter power required.

Determining the input voltage of your inverter: 12V or 24V

If you are looking for an inverter for your 12V leisure battery in a motorhome, caravan or boat, there isn't much choice in terms of the input voltage - you will need a 12V to 230V inverter, because your battery is 12V.

However, if you are building a standalone off-grid solar system (e.g. in a house, garden, shed or farm), then you can choose the voltage of your battery bank, and consequently, the input voltage of the inverter.

Instead of a 12V battery bank, you may choose to build a 24V battery bank (2 x 12V batteries wired in series will produce 24V). In this case you can use a 24V DC to 230V AC inverter, rather than 12V DC to 230V AC. This set-up will provide some important benefits:

• The input current for the inverter will be two times smaller for 24V than for 12V, making the inverter and the entire system safer and more reliable
• The cables between your battery and the inverter do not have to be as thick as those used for a 12V battery bank and inverter.

This is particularly important for large standalone solar systems with 2000W inverters. For such power levels, our recommendation is to opt for a 24V battery bank and an inverter with a 24V input voltage.
