A sine wave inverter is designed to convert power from a battery into the exact type of power found in standard wall outlets in homes or offices.
To be more precise, these inverters convert direct current (DC) sourced from a battery into alternating current (AC). The resulting AC power is suitable for operating various appliances, lamps, light strips, compressors, and other devices that cannot function directly on battery power.
Types of Sine Wave Inverter
There are two main types of inverters that you will come across: pure sine wave and modified sine wave inverters.
1. Pure Sine Wave Inverter
They produce AC power that matches the sine wave of wall outlets. They work steadily with a continuous wave providing a smooth and periodic oscillation. Pure sine wave inverters are the best choice for running any equipment that requires a pure sine wave.
Devices compatible with pure sine wave inverters are
- Appliances with AC motors, such as refrigerators, compressors, and microwaves, require pure sine wave inverters.
- Other devices that require pure sine wave inverters include bread makers, specific battery chargers, and light dimmers.
- Audio and video equipment, as well as satellite systems, fall into the category of devices that need pure sine wave inverters.
- Certain medical equipment, including many CPAP devices for sleep apnea and oxygen concentrators, rely on pure sine wave inverters for proper operation.
2. Modified Sine Wave Inverter
They generate a specific kind of sine waveform that is the easiest to generate. The polarity changes quickly from positive to negative, creating a waveform that resembles a square wave rather than the smooth arc of pure sine inverters.
Usually, most equipment may work fine with it. But certain devices may be unable to operate or may be damaged when used with a modified sine wave inverter, if not compatible.
List of incompatible devices for Modified sine wave inverter
- Motors, and devices or appliances with motors: fans, microwaves, and refrigerators
- All appliances that have digital clocks or electric timers
- Devices that use electric temperature controls or adjustable speeds
- Some fluorescent lights may not be as bright and others may make buzzing noises.
