A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC).

A transfer switch is essential when using a power inverter which is connected to an AC source.So that the inverter is not “backfed” when power is applied to the same line. A electrical transfer switch is a switch that switches a load between two sources, most commonly for us an inverter and incoming
