Understanding Pure Sine Wave Inverters and Other Inverter Types
When shopping for a marine inverter, RV inverters and car inverters it is important to note that there are two basic types of inverters on the market. Understanding the differences and pros and cons of each of these inverters is important in order to make certain you purchase the type of inverter that will best suit your needs.
The two basic types of inverters include:
pure sine wave inverter, which is also referred to as a "true" sine wave, utilizes sine wave in order to provide your appliances with power. A sine wave, which is produced by rotating AC machinery, is the type of wave that is generally provided by the utility company with the help of a generator.
The benefits of using a pure sine wave inverter include:
All equipment currently on the market is designed for use with sine waves.
Some appliances, particularly microwaves and variable speed motors, will not produce full output if they do not use sine wave power.
Some appliances, such as light dimmers and bread makers, will not work at all without sine wave power.
On the downside, pure sine wave inverters are more expensive than the other two types of inverters. By looking out for discount inverters that are on sale, however, you can keep your costs down.
Modified Sine Power Inverter
The modified sine inverter is different from a pure sine power inverter because the wave is in more of a step wave and because appliances are not specifically designed to work with this type of inverter. Although many appliances will still work with a modified sine inverter, some may not work as efficiently. As such, it may take more power to run appliances with a modified sine inverter.
Using fluorescent lighting can be problematic when using modified sine power inverters. For example, they may not get as bright and some may make buzzing noises when on. Certain appliances with digital clocks or electronic timers may also work improperly with this type of inverter because the waves are rougher and cause extra "noise" to be created in the line. Furthermore, appliances that use electronic temperature controls will not be able to properly control the temperature when using modified sine wave marine inverters, RV inverters or car inverters.
Despite the few problems associated with them, most equipment can run just fine with modified sine wave inverters. In addition, since they are less expensive than the pure sine wave inverters, they are the most commonly used inverter. In fact, it can sometimes be difficult to find options other than modified sine wave inverters.
