Abstract: A microinverter comprises a housing, a cover configured to connect to the housing, and electronics mounted within the housing to convert direct current from a solar panel to alternative current. The housing includes a first side wall, a second side wall perpendicular to the first side wall, and a mounting flange extending from the side walls, the mounting flange including a first channel configured to receive a first rail segment of the solar panel, a second channel configured to receive a second rail segment of the solar panel, and a mounting tab disposed between the channels to receive a fastener extending through one of the rail segments, thereby securing the housing to the solar panel with a single fastener.

Abstract: A single-phase DC-AC converter generates an AC voltage with five levels at the output converter side by using four controlled power switches. The converter has a relationship between the number of levels per number of switches (nL/nS) of five to four. The converter reduces the number of semiconductor devices required to generate a high number of levels at the output converter side, requires only one DC source to generate an AC output, and operates with high efficiency.
