Product Brochure

ABB now offers the UL 1741 certified
Solar Rapid Shutdown Device, PV Vault
™
rated at 600 V DC to meet NEC 690.12
code requirement for string inverters.
This product provides a safe solution for
emergency responders, homeowners
and contractors to eliminate voltage
in compliance with NEC 2014 Rapid
Shutdown requirements.
The ABB PV Vault
™
system requires no
extra conduit; minimizing material cost
and associated labor.
Shutdown occurs at the rooftop box
when utility/inverter power is lost or when
the PV control vault power located at or
near the inverter is turned off. In areas
requiring a dedicated activation switch,
an optional stop button is available.
With its slim-line design, the PV Vault
™
controller can mount directly to the PV
mounting rail and lay parallel to the
roofing surface. The NEMA 4X enclosure
permits installation angles from 0-90°
while maintaining its water-tight seal
from accumulating snow or driving rain.
Three models are available to cover
all system configurations including
a two-string pass-through, a two-
string combined and a four-string
combined box.
The unique features of each box
can be used to maintain the specific
configuration of the PV system. Dual
outputs in the box maintain the benefits
of dual inverter channels, while a single
output box is ideal for small PV arrays
utilizing one MPPT channel.
To further reduce system cost, string
combining models reduce the number of
output conductors between the rooftop
box and the inverter.
The rapid shutdown boxes includes a
disconnect switch to comply with NEC
2014 690.15(C) Direct-Current Combiner
Disconnects.
Highlights:
− Meets NEC 690.12 while avoiding
the cost of additional conduit, making
this solution the most cost-effective
rapid shutdown product available
