A former electrical engineer at Bechtel Power Corporation in Norwalk, California, Dianoush Emami has worked as an electrical engineer for more than three decades and has overseen numerous design/project management, electrical engineering, and design construction operations. Dianoush Emami was in charge of specification administration for the Alvin F. Vogtle Nuclear Power Plant project, which included several contracts, including inverters. A solar inverter converts the direct current generated from photovoltaic cells in solar panels to alternating current. Alternating current is the type of electric current that is used in homes. There are different types of solar inverters, and a popularly known type is the string inverter. A string inverter has to be installed near electricity meters and service panels since it must be connected in series to the solar panel. Residential solar installations typically use one string inverter. The device is easy to troubleshoot since it's often the only one. Troubleshooting the inverter will most likely solve the problem if there is a power failure. Unlike string inverters, microinverters (another type of inverter) are often installed behind each solar panel, which makes troubleshooting difficult since the engineer may have to climb the roof and check the inverters one by one. Installing string inverters saves cost and labor and needs fewer connections with solar panels. With fewer connections, there is a limited chance of faulty connections.
