TECHNICAL COMPARISONS.
Evergreen Energy Solutions Limited is presenting now EVERHOME, a very reliable DC-AC True Pure Sine Wave Inverter technology able to handle the most exigent and heaviest loads today.Evergreen Energy Solutions Limited, during more than three years, has spent a lot of technical and component resources developing the best protection circuits, strongest DC-AC Inverter full bridge modulation firmware in order to provide a product that, despite others in the market, is really well protected against overload and short-circuit conditions, with minimum output voltage distortion vs. load connected. And of course, the best price/benefit ratio.

PURE SINE WAVE VS. MODIFIED STEP SINE WAVE.Let us to compare the typical two inverter wave forms. For modified Step Sine inverters, the wave form starts at zero voltage going up, it then starts back down passes zero to the negative peak and then on to the next zero voltage going up. This is called one cycle or a hertz. Normally there are 60 or 50 of these cycles or 60/50 hertz per second in a sine wave depending of the country.For AC inverter modified sine wave form it has a step up, step across, and step down form. It is like the crude square wave form because it clips the tops and bottoms off the wave making a flat and is either strait up or down when going to the positive or negative side ends. It just has an extra step at zero voltage. These flat spots in the wave form is where the hammering sound comes from in electric motors and the noise you hear in some radios. An electric motor or compressor will not have as long of a life using this type of inverter wave form. We can resume the potential problems you can found using Modified sine wave inverters as follow:

-Radio hum.
-Lines on television screens.
-Buzzing of fluorescent lights, dimmer switches, and ceiling fans.
-Malfunctioning of electronic controls.
-Increased heating of transformers and electric motors.
-Lowered performance and efficiency and shortened life span of electric motors, etc.

For true sine wave inverter, it is the type of wave form you would see from the city electric grid. It is what that you find in your home. This is the type of wave form you find in a True Sine Wave DC-AC Inverter. Smooth and rounded all the way. Motors will run quiet and radios will not have the interference like with a modified sine wave inverter. Just looking at the two wave forms you can see how much better things would run with a true sine wave inverter.
If you want to run your equipment exactly to the manufacturer's specifications, choose a true sine wave inverter. With true sine wave, motor loads start easier and run cooler. Some equipment only operates properly with true sine wave power like laser printers, variable speed motors, AC-DC drivers for LED and digital clocks.Waveform is an important consideration when choosing an inverter. Pure sine wave inverters provide premium power that is identical to or even better than power supplied by your utility company.Frankly speaking, Modified Sine Wave has been until now the wave form most inverters produce. Ultramodern washing machines and a few other appliances with electronically controlled, variable-speed motors won't work at all on modified sine wave power, and some people in this field come down hard on modified sine wave inverters because of this. However, modified sine wave inverters aren't as bad as all this might make it seem.Most people experience no problems whatsoever with their modified sine wave system: Evergreen Energy Solutions Limited also provides EVERHOME Modified Sine Wave Inverters from 150W to 1200Wgreat for low cost, off-grid homes and backup systems. Despite the claims, modified sine wave inverters work perfectly well with lot of appliances including most stereos and computers.
