Reliable Pure Sine Wave Inverter Selection
Learn how to choose, install, and use pure sine wave inverters to protect your electronics and keep everything running during blackouts and off-grid adventures.
"Pure sine wave" refers to the smooth, rounded pattern of electricity these inverters produce. It perfectly matches utility power with its gentle up-and-down curve. In contrast: The inverter transforms DC to AC through three simple steps: While more expensive, pure sine wave inverters provide the safest power for all devices.
Modified sine wave inverters use simpler and cheaper electronics to produce a wave that is not quite a smooth sine wave. Pure sine wave inverters use more expensive electronics to generate a wave that is very close to a pure sine wave. The figure below compares outputs from a modified sine waver inverter and a pure sine wave inverter.
They convert direct current (DC) energy, such as that sourced from solar panels or batteries, into alternating current (AC) energy, the type used in most residential and commercial settings. A sine wave inverter operates by transforming a DC input into an AC output that closely mimics the pure sine wave of traditional power grid electricity.
A pure sine wave inverter generator is necessary when you need to power sensitive electronics. Some examples include running laptops, desktop computers, gaming consoles, audio equipment, or medical devices that require a stable and clean power supply.
