Abstract
Official abstract text for this publication.
A method and apparatus for a smart junction box including: a first set of switches connected across input terminals adapted for connection to output terminals of a plurality of photovoltaic (PV) modules, a plurality of diodes connected across input terminals of each respective switch in the first set of switches, at least one reverse current detection device on at least one output terminal of the smart junction box, a second set of switches to selectively disconnect and short circuit output terminals of the smart junction box when a reverse current is detected, and wherein at least one switch of the second set of switches is located across the output terminals, a controller for controlling the first and second set of switches.
