Description
Midnite Solar MNPVbirdhouse Emergency Remote Disconnect Switch
Birdhouse – Emergency Disconnect Switch
The firefighter approved “Birdhouse” remote actuator should be installed in a visible, easily accessible location so that the array combiners can safely be disconnected from the ground when necessary. The hard wired connection to the disconnect combiners provides positive feedback that the disconnect on the roof has actually been thrown. One Birdhouse can be used to disconnect multiple combiners. The Birdhouse has a speaker and will announce when it is safe to climb onto the roof, and during the day it will inform that there is still voltage present up to the combiner. At night, it will announce that there is no PV voltage present. The Birdhouse is powered by multiple redundant sources. The combiner can be powered using the array using the MNDiscoPSB power supply (standard on the Arc-fault combiners) that will also power the Birdhouse. The Birdhouse also comes with an indoor 120 VAC power supply that can be used as a DC supply, and has an internal backup battery. The power draw of the Birdhouse is only 1 W. Use 600 V CAT5 USE-2 compliant wire to connect the Birdhouse and combiners.
NOTE: FOR THE BIRDHOUSE TO WORK WITH YOUR DISCONNECTING COMBINER YOU WILL NEED TO PURCHASE THE POWER SUPPLY BOARD MNDiscoPSB.
* Located at ground level, the Birdhouse provides a safe means to disconnect high voltage PV arrays from MidNite Disconnecting and Arc Fault combiners.
* Hard wired connection gives positive feedback that the Disconnect on the roof has actually been thrown. Connection is via 600/1000v Cat 5 USE-2 cable
* Up to four separate means of power including battery backup insures that the disconnect will be tripped when the button is pushed
* Voice confirms level of safety (day or night) to the person pushing the button
* Nema 3R UV resistant enclosure
* Able to disconnect multiple PV Disco Arcfault Combiners
* Firefighter Approved
* 600V Cat 5 USE-2 cable $1.39 per ft.
