One inverter per panel
Solar panels make direct current (DC), and homes run on alternating current (AC). Most systems used one central inverter for the whole array. Enphase’s microinverter converts the power at each panel instead. In June 2008 it announced what it called the solar industry’s first microinverter system, with commercial shipments starting in mid-2008.
