What type of inverter should I buy?

It is understandable if you feel flummoxed when you first delve into the complex world of power inverters. While they are simple to use, the technology behind them is quite technical, but rest assured, we will explain what you need to know as simply as possible so you can make an informed decision about what the best inverter is for your RV.

You will notice that the inverters on the market are described as either ‘pure sine wave’ or ‘modified sine wave’. It will also not have escaped your notice that the pure sine wave inverters have a heftier price tag.

The distinction is this: with a modified sine wave inverter the power that reaches your electrical devices will be coming in square waves whereas with pure sine waves the power comes in evenly distributed arching waves. The difference in the waveform effects the efficiency of the power received. With modified sine waves the power reaches your devices in a less ‘pure’ form and, subsequently, means they run less efficiently, are more likely to overheat and may even not work at all. This type of waveform can sometimes damage your devices and create unwanted noise.

Pure sine wave inverters, while pricier, deliver power that is practically the same as the power you receive when you plug in your devices at home. This is a much purer waveform and you can pretty much guarantee that it will work with all of your onboard RV electronic devices. You can also be confident that your devices are protected from damage. Cosuper CPT series pure sine wave inverter/charger, In the European and American RV market, after years of use, the performance is stable and easy to operate, and it is loved by Europeans and Americans.

If you are just needing to power the basics such as your kettle and hair-dryer a modified sine wave inverter can power up these devices just fine. However, if you are relying on your inverter to charge your phone, laptop or other more expensive and technical devices then it is worthwhile to invest in a pure sine wave inverter for your RV so that you don’t have to replace these items earlier than expected.

Of course, choosing an inverter, not only to consider the inverter's waveform, but also to consider other characteristics of the inverter, for example, whether the voltage matches your RV/system voltage, whether the power is sufficient, installation Size and more.
