PV stop potential voltage and hazard stop system

A system for personnel at readily accessible locations comprising:

• an enclosure, said enclosure comprising a modular main control panel enclosure containing a communications module used to transmit and receive data to/from junction boxes/enclosures that are paired to it, and a processor board handling all front panel peripherals, displays, devices, and interaction, interfacing one or more components within said modular main control panel enclosure to external devices, supporting protocols for remote operation and telemetry, data logging for performance and forensic applications, and interaction with security and/or fire systems;
• wherein said main control panel enclosure monitors contact closures that are interfaced as needed to existing or future devices to allow these devices to request a shutdown of a PV module or modules;
• within said enclosure, one or more electrical and, if present, mechanical transmitting and receiving devices, including connection to at least one PV supply source;
• and
• within said enclosure, one or more microprocessors or controllers that via a relay electrically connected to junction box lead lines switch completely off the source or line supply of all potentially hazardous equipment or energized/charged systems in a facility;
• an indicator configured to provide an audible and/or visual indication that power is either off or on;
• the system requiring a lockout code or lockout mechanism in order to re-energize the source or line supply;
• wherein one or more devices to effect on or off status of a solar PV energy system at the immediate location of the tabs or busbars exiting the PV module prior to the terminal blocks in a junction box/enclosure, inverter or combination inverter/junction box/enclosure so as to be able to render all conductive elements downstream of the busbar/tabbing of the solar unit in either on or off status;
• and
• wherein the junction box/enclosure provides safe operation of the attached equipment to prevent unsafe or unexpected startup, unsafe or unexpected shutdown, or improper sequencing, any of which could potentially occur after a loss of power at the junction box/enclosure, main control panel, or both.
