Pure Sine Wave Inverters

Why Are Pure Sine Wave Inverters So Expensive?
Pure sine wave inverters provide a clean and reliable electric current, the same quality the utility grid delivers. To achieve this high quality, they use high-end electronic components, unlike modified sine wave inverters that contain only cheap electronics.

Therefore, for a similar wattage output, a pure sine wave could be 2 times more expensive than a modified sine wave.

However, do keep in mind that pure sine wave inverters will protect your equipment and therefore increase their life duration. In addition, you will save energy with a pure sine wave inverter because of its high efficiency (+90%).
