Abstract
A solar photovoltaic module safety shutdown system includes a module-on switch coupled with a first circuit having a photovoltaic module and a System-Monitor device. The System-Monitor device couples to the module-on switch through a second circuit and to the photovoltaic module and an AC main panelboard through the first circuit. A module-off switch operatively couples with the photovoltaic module and the module-on switch. The System-Monitor device supplies a System-on signal to the module-on switch through the second circuit. The module-on switch disables the photovoltaic module by shorting it or disconnecting it from the first circuit in response to the System-On signal not being received by the module-on switch from the System-Monitor device. The module-off switch disables the photovoltaic module by shorting it in response to the System-On signal not being received by the module-on switch when the photovoltaic module is irradiated with light.
