A pure sine wave inverter is a device that converts direct current (DC) such as what's produced by a solar system or RV batteries, to usable alternating current (AC) that most appliances use. A sine inverter takes the DC output of your solar array, converts it to AC, and does so in a way which replicates as closely as possible the pure sine wave of grid power alternating current.
