What is Grid-Tied Inverter?

Sometimes referred to as a grid-interactive inverter. A device converting DC into AC and feeding electricity into the power grid of residential and commercial buildings on the customer side of a utility meter. This reduces the amount of electricity bought from the grid operator. Sometimes, the system may generate more electricity than needed, which causes the meter "backward" running. In this case, a utility may optionally grant a customer with a credit for the back-fed electricity. Wind and solar installations are the most widespread sources of direct current power.
