A disconnect unit and an associated method in a photovoltaic system includes a plurality of input power lines configured to receive power from a photovoltaic (PV) generator, and deliver the received power to an inverter. The disconnect unit further includes a sensor configured to determine a voltage at the plurality of input power lines, and a controller configured to selectively disconnect and reconnect one or more of the plurality of input power lines based on the determined voltage.
