FEATURES
Communication Power line
Integrated ground The DC circuit meets the requirements for ungrounded PV arrays in
NEC 690.35. Equipment ground is provided in the Engage Cable. No additional
GEC or ground is required. Ground fault protection (GFP) is integrated into the
microinverter.
Monitoring Enlighten Manager and MyEnlighten monitoring options
Transformer design High frequency transformers, galvanically isolated
Compliance UL 2703 recognized, UL1741/IEEE1547, FCC Part 15 Class B,
CAN/CSA-C22.2 NO. 0-M91, 0.4-04, and 107.1-01
1. No enforced DC/AC ratio. See the compatibility calculator at enphase.com/en-us/support/module-compatibility.
2. Frequency ranges can be extended beyond nominal if required by the utility.
