Planning for Microinverter Installation

The M215 is compatible with most 60-cell PV modules (to 270W or higher) and installs quickly and easily.
It works with either three-phase 208 VAC or single-phase 240 VAC services. The M215 ships with
integrated DC and AC cables and connectors. The DC connectors attach to the PV module, while the AC
connector attaches directly to the Engage Cable. No additional cabling is needed.
The Engage Cable is available in two connector spacing options and two voltage types to meet varying
site requirements. For Engage Cable ordering information, see "Engage Cable Planning and Ordering
Information" on page 29.
WARNING: Be aware that installation of this equipment includes risk of electric shock.
Normally grounded conductors may be ungrounded and energized when a ground fault is
indicated.

Compatibility and Capacity

The Enphase M215 Microinverters are electrically compatible with most 60-cell PV modules. For more
information, see "Technical Data" on page 26 of this manual. Refer to the Enphase website
(http://www.enphase.com/support) for a list of electrically compatible PV modules and approved PV
racking systems. To ensure mechanical compatibility, be sure to order the correct connector type for
both microinverter and PV module from your distributor.
WARNING: The M215 may be paired only with a 60-cell PV module.
