This MidNite Solar Birdhouse is a firefighter/home owner's control device designed specifically for disconnecting rooftop PV panels at ground level. In case of emergencies or system maintenance, the press of a big red button disconnects inherently hazardous voltages.
The Birdhouse woks in conjunction with MidNite Solar's disconnecting combiners. It's designed to be mounted withing 500 meters (1640 ft) of the combiner and located near rooftop access points such as doors and ladders.
The Birhouse's LEDs display the system status and automated speech gives further situation specific instructions. The Birdhouse has an attractive weather resistant enclosure made of anodized aluminum and high density plastic.

Article 690 of the NEC 2014 increases the electrical and fire safety of photovoltaic (PV) systems on buildings-in particular, for the emergency responders working on or near the power lines that may potentially contain live PV circuits. For PV systems installed on roofs of buildings, PV source circuits must be de-energized within 10 seconds of when emergency shutdown is initiated or when the PV power source disconnecting means is opened.
MidNite Solar has all the needed equipment to install the Emergency Shutdown systems, including the battery disconnect modules to allow for disabling anything battery based including the Inverter and AC generator.
