A modified sine wave inverter is an electrical device that converts direct current (DC) into alternating current (AC). The output of a modified sine wave inverter is not a perfect sine wave, but it is good enough for most purposes.
The main advantage of a modified sine wave inverter is that it is much cheaper than a true sine wave inverter. Modified sine wave inverters are also smaller and lighter, making them more portable.
One downside of modified sine wave inverters is that they can produce a humming sound, which can be annoying. Additionally, they may not work with some sensitive electronic equipment.
If you're looking for an inverter for general use, a modified sine wave inverter is a good choice. Just be aware of the potential downsides before making your purchase.
