This product is UL Listed as PV Rapid Shutdown
Equipment and conforms with NEC 2014, NEC 2017,
NEC 2020, and NEC 2023 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.
1. No enforced DC/AC ratio.
2. The 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.
4. IQ8X is not certified for use with Enphase Three Phase Network Protection Relay (NPR-3P-208-NA) and, therefore, designed for
single-phase operation only. Check with the local utility requirements to install a single-phase inverter across three phases.
