*A Note Inverters
Inverters come in two varieties: Modified Sine Wave, and Pure Sine Wave. If an inverter does not explicitly state that it is Pure Sine Wave, then it is a modified model.
The difference between a modified wave and a pure sine wave is in the quality of the waveform as the inverter creates AC power from DC. Advanced switching circuitry enables pure sine wave inverters to more accurately mimic the power you find in your household outlets.
Modified sine wave inverters are fine for most applications - particularly where the appliance has its own power adaptor, such as with chargers and laptop computers. Some types of audio equipment, like personal stereos or amplifiers, will create a 'buzz' when running on modified sine wave power. Some motorized equipment will also not perform properly on this type of power. These are the situations where a pure sine wave inverter is the right choice. The cleaner power will eliminate any 'buzzing' or other operational issues. A pure sine wave inverter is also a good choice when the equipment being used is sensitive, such as with research or medical equipment.
