Compliance
CA Rule 21 (UL 1741-SB), UL 62109-1,
UL1741/IEEE1547, FCC Part 15 Class B, ICES-0003
Class B, CAN/CSA-C22.2 NO. 107.1-01
This product is UL Listed as PV Rapid Shut Down
Equipment and conforms with NEC 2014, NEC 2017, and
NEC 2020 section 690.12 and C22.1-2018 Rule 64-218
Rapid Shutdown of PV Systems, for AC and DC
conductors, when installed according to manufacturer’s
instructions.
Grounding
The DC circuit meets the requirements for ungrounded PV
arrays in NEC. Ground fault protection (GFP) is integrated
into the class II double insulated microinverter
Monitoring
Enphase Installer Platform and Enphase App monitoring
options. Both options require an Enphase IQ Gateway
Communication
Power line communication (PLC)
(1) No enforced DC/AC ratio. See the compatibility calculator at https://link.enphase.com/module-compatibility (2) Nominal voltage range can
be extended beyond nominal if required by the utility. (3) Limits may vary. Refer to local requirements to define the number of microinverters per
branch in your area.
