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 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 1000W 48V pure sine wave power inverter can generate 1000W of continuous power and up to 2000W of power at peak times (peak time reserve capacity is useful in case more energy is required to start an appliance than for its continuous running).

This product comes with important protection and safety features, such as over-discharge, overload, overheating and short-circuit automatic shutdown.

There is also a USB port which can be used for charging mobile phones, tablets, laptops, MP3 players and other USB-compatible devices.

Which appliances can be powered?

If you are unsure whether 1000W is sufficient for your appliances, please see the following table:

The product comes with a user manual which explains wiring and operations (see Documents tab).

How do you install this inverter?

Simply connect it to your 48V battery or battery bank, plug your appliances into the inverter, turn the power switch on and they will start running. An adaptor may be used for more sockets, provided that the total power consumption of all appliances connected to this inverter is within 1000W.

Note for users of our solar charging systems: this inverter can be connected to your 48V battery / battery bank alongside any of our solar systems or charging kits. If you already have one of our 48V solar charging kits with a charge controller connected to your 48V battery, this inverter can be added at any time (connect the inverter to your battery in parallel with the solar controller and 48V 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 the inverter to your 48V battery directly.

If you don't have one of our 48V solar charging kits but plan to build an off-grid solar system with 230V mains output, we recommend using 48V batteries / 48V solar charging kits alongside this inverter with a 48V input voltage, rather than having 12V / 24V components and an inverter with a 12V / 24V input voltage.

48V system components provide the following benefits: 

  • The cables for 48V do not have to be as thick as those required for 12V or 24V
  • The input into the power inverter will have a smaller current (Amps) than that of a 12V or 24V system, making the whole system more stable and reliable.
