Abstract
A power generation system including a plurality of isolated power converters and a plurality of first weatherable units is provided. Each of the isolated power converters includes a primary stage, a secondary stage and a transformer providing an electrically contactless connection between the primary and secondary stages. The first weatherable unit includes a photovoltaic module coupled to the primary stage of a respective one of the plurality of isolated power converters and a primary side of the transformer. The system further includes a plurality of second units, each having a second side of the transformer coupled to the secondary stage of a respective one of the plurality of isolated power converters. The system also includes a direct current (DC) to alternating current (AC) inverter and a connection unit for coupling the secondary stages of the isolated power converter and the DC to AC inverter. The DC to AC inverter is configured to transfer power from the photovoltaic module to a power grid.
