FEATURES

Compatibility 60-cell PV modules

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

Compliance UL1741/IEEE1547, FCC Part 15 Class B,

CAN/CSA-C22.2 NO. 0-M91, 0.4-04, and 107.1-01

1. Suggestion only, inverter self limits DC inputs.

2. Nominal voltage range can be extended beyond nominal if required by the utility.
