What is an inverter?
The primary function of an inverter is to provide power to AC equipment, which typically operates on the same frequency as the power grid. Inverters are commonly used in solar energy systems and solar panel installations. They convert DC electricity produced by the solar panel into AC power for use in your home or business.
How does an inverter work?
So, how does an inverter work? The process starts when the DC power supply is fed into the Inverter, where the DC is regulated into a steady waveform. The Inverter then converts this DC waveform into an AC waveform through a process known as pulse width modulation.
Types of inverters
Different types of inverters are available, depending on the specific need for which they are intended. Standard inverters include Grid-tie inverters, Standalone inverters, and Battery Backup inverters.
Difference between pure sine wave and modified sine wave inverters
Battery Backup inverters are designed to provide backup power in case of a grid failure, utilized most commonly in residential homes. They work with a battery bank, and its DC power is converted to AC power for use in your home.
Another aspect of inverters that is equally important to be aware of is the difference between pure sine waves and modified sine waves. A pure sine wave inverter produces a waveform that is identical in shape to the AC waveform generated by the power grid. This provides much greater efficiency and compatibility with a broader range of electronic devices.
On the other hand, a modified sine wave inverter produces an approximation of the AC waveform, which may be unsuitable for some equipment. This is because modified sine wave inverters carry a higher level of distortion than pure sine wave inverters.
