PV rapid shutdown must be installed and operational, including activation devices and required
markings.
The Enphase IQ8 Commercial Series Microinverter is UL Listed as PV rapid shut down equipment and
conforms with NEC Section 690.12 rapid shutdown of PV Systems for AC and DC conductors when
installed according to the following requirements:
• Microinverters and all DC connections must be installed inside the array boundary.
Enphase further requires that the microinverters and DC connections be installed under the
PV module to avoid direct exposure to rain, UV, and other harmful weather events.
• The array boundary is defined as 305 mm (1 ft.) from the array in all directions or 1 m (3 ft.)
from the point of entry inside a building.
This rapid shutdown system must be provided with an initiating device and (or with) a status
indicator, which must be installed in a location accessible to first responders or be connected
to an automatic system that initiates rapid shutdown upon the activation of a system
disconnect or activation of another type of emergency system. The initiator shall be listed and
identified as a disconnecting means that plainly indicates whether it is in the “off” or “on”
position.
Examples are:
• Service disconnecting means
• PV system disconnecting means
• Readily accessible switch or circuit breaker
The handle position of a switch or circuit breaker is suitable for use as an indicator. Refer to NEC for more
information. Additionally, in a prominent location near the initiator device, a placard or label must be
provided with a permanent marking including the following wording:
’PHOTOVOLTAIC SYSTEM EQUIPPED WITH RAPID SHUTDOWN’ The term ‘PHOTOVOLTAIC’ may be
replaced with ‘PV.’ The placard, label, or directory shall be reflective, with all letters capitalized and
having a minimum height of 9.5 mm (3/8 in) in white on a red background.
