The Power Inverter: Usage, different Models and Curiosities

A power inverter, also known as a power inverter, is an electronic device designed to convert direct current (DC) to alternating current (AC). This allows electrical equipment and devices that run on alternating current to be used through a DC power source, such as a battery or solar panel.


What is a power inverter used for?

A power inverter is particularly useful in several situations, such as:

  1. Camping: You can use it to power electronic devices such as laptops, lights, portable refrigerators and more while camping.
  2. Vehicles: In some vehicles, such as RVs and boats, power inverters are used to supply power to household appliances even when the engine is not running.
  3. Emergency situations: In case of power outages or interruptions in the power supply, a power inverter connected to a battery can provide power to power essential devices such as lights or small appliances.
  4. Solar power: In photovoltaic systems, power inverters convert the energy generated by solar panels from direct current to alternating current, which can be used to electrically power a home or building.

Models of power inverters:

There are various models of power inverters, which differ mainly in the power output and the waveform of the AC produced. The main models are:

  1. Square wave inverter (modified sine wave): This is the cheapest model but may be less suitable for sensitive or delicate devices because the waveform generated is not perfectly sinusoidal.
  2. Pure sine wave inverter (pure sine wave): These inverters produce a waveform similar to that of the household power supply. They are ideal for powering sensitive and complex devices such as computers, medical equipment, televisions and electric motors.


  • Some power inverters have USB ports to directly charge mobile devices without the need for an additional adapter.
  • Some inverters have advanced features such as the ability to monitor and display input and output voltage, power consumption, temperature, and even more.

Differences between Europe and the US

The main differences between inverters used in Europe and those in the United States are mainly in the voltage and frequency of the AC. In Europe, the standard voltage is 230 V and the frequency is 50 Hz, while in the United States the standard voltage is 120 V and the frequency is 60 Hz. Thus, inverters used in Europe are designed to generate alternating current at 230 V and 50 Hz, while those in the United States generate alternating current at 120 V and 60 Hz.

If you use a power inverter designed for the European market in the United States, or vice versa, you should pay attention to proper voltage and frequency management to avoid damage to connected equipment. In addition, you may need to use adapters or transformers to match the specifications of the power inverter to local requirements.
