Inverter Generators

Inverter generators are next-generation portable generators that are clearly setting a new standard in generator technology.

Inverter generators are next-generation portable generators that are clearly setting a new standard in generator technology. An inverter converts independent DC current into standard household AC current. New technology now allows converters to be of high efficiency in conjunction with a generator, resulting in a number of advantages.

The new inverter generator system, using PWM (Pulse Width Modulation), supplies of high quality electricity that could not be achieved by merely trying to improve the conventional alternator type generator. Using revolutionary inverter technology, inverter generators take the raw power produced by the generator and pass it through a special microprocessor that provides ultra-clean power that boasts a sine wave equal to or better than the current from your household AC wall outlet. This means that for the first time, you can operate a computer or other surge sensitive equipment from a remote location without the fear of interrupted service or damage to the equipment. Inverter generators boast a waveform distortion ratio of less than 2.5.

What this means practically to you is as follows: Computers and power-sensitive equipment require what is referred to as "clean power." Clean power is electrical current that is consistent and has a stable "sine wave" or signal. If the lights or appliances in your home were being powered and there was a fluctuation in the AC power, you’d probably see the lights dim and then return to full brightness—no problem! However, if your computer was being powered by a generator and the voltage fluctuated, chances are the computer would either shut down or at least interrupt the program you were working in. Inverter generators overcome this problem. In addition, the unique technology offered by inverter generators results in several other advantages:

Compact and Lightweight: Inverter generators' greater efficiency allows reduction in overall size and weight by about one-third vs. similar class generators. This reduction is possible due to the fact that inverter generators have the alternator built into the engine itself, eliminating the need for a bulky (and heavy) independent alternator. A lone operator can easily carry, set up, and run smaller inverter generator models. Easy-grip frame designs, plus wheels on some inverter generator models, maximize handling ease throughout the range of larger inverter generator models.

Meet a Wide Range of Power Needs: Inverter generators can be used to power everything, from construction equipment that demands high voltage, to sensitive microcomputer-fitted appliances.

Very Low Noise: Significantly quieter operation due to inverter generators' fast, efficient switching of current waveform. The engine need not work as hard to generate high levels of electrical power. Unique soundproof panels, vibration control and soft-tone mufflers further reduce noise.

Low Fuel Consumption: Inverter technology, combined with more sophisticated throttle control, automatically adjusts engine speed to electrical load, reducing fuel use by about 20% vs. similar class generators. Meets Strictest Environmental Regulations: U.S. Phase II and CARB Tier II.
