A disconnect system for a solar installation shuts down power upstream from an inverter, so that it is safe for solar field personnel to perform work related to a solar installation. The system actuates multiple disconnect devices in one motion by a linkage assembly which can associate 2-4 disconnect switches with a single handle. This system preferably includes hardware and logic for monitoring the current and voltage output of electrically coupled combiner/recombiner boxes in the solar field, and for wirelessly transmitting this data to a user. A single disconnect cabinet can accommodate 2-20 inputs from associated lead assemblies and/or recombiner lead assemblies with 5 handles or less.
