If you’ve been researching 12v inverters, you’ve probably read about pure sine wave inverters.  If you researched further, you also probably realized that pure sine inverters are the most expensive type and in many cases the cost is just too high for the average person.

You’ve probably wondered if you really need a pure sine 12v inverter?  Pure sine wave inverters output power that is as good or better than the power supplied from the electric company.  Low quality power inverters output square sine wave power.   The is dirty power and may cause interference on some electronic devices.  Most mid to high end inverters output modified sine wave power.

For the average user, a good modified sine wave 12 volt inverter will be quite adequate.  I have a modified sine inverter that powers my remote home.  I run three computers, three televisions, Dish Network DVR satellite receiver, DVD players, a playstation 2,  a Nintendo Wii, and a wireless router on it.  We have never experienced any problems powering them with a modified sine wave inverter.

The only time I ever had a problem was when I had a cheap power inverter that I bought at a local department store.  We didn’t have satellite yet and could only watch TV with an antenna.  When we used the inverter to watch TV, we would see some horizontal lines on the screen.  I bought a better 12 volt inverter, subscribed to satellite, and the lines went away.

If you’re like most people and can’t afford the most expensive pure sine wave power inverter, a quality modified sine wave inverter should suit your needs just fine.
