Planning For Microinverter Installation - enphase IQ8MC Installation And Operation Manual

Planning for microinverter installation

IQ8 Series Microinverters support PV modules with 54-cell/108-half-cell, 60-cell/120-half-cell,
66-cell/132-half-cell, and 72-cell/144-half-cell configurations. Modules can be paired as long as the
maximum input voltage is not exceeded and the maximum input current of the inverters at the lowest
and highest temperatures is respected. Installers should not exceed the small-scale technology
certificate (STC) limit on PV module wattage for claiming the STC. See the compatibility calculator at
https:/ /enphase.com/en-au/installers/microinverters/calculator.
The microinverter housing is designed for outdoor installation and complies with the IP67 environmental
enclosure rating standard.
IP67 rating definition: Indoor or outdoor use primarily to provide a degree of protection
against hose-directed water, the entry of water during occasional temporary submersion at
a limited depth, and damage from external ice formation.
IQ Cables are available with connector spacing options to accommodate the installation of PV modules in
portrait or landscape orientation. For IQ Cable ordering information, refer to
ordering.
Compatibility
The IQ8 Series Microinverter is electrically compatible with PV modules, as listed in the following table.
For specifications, see "Technical
calculator at https:/ /enphase.com/en-au/installers/microinverters/calculator
electrical compatibility. To ensure mechanical compatibility, a microinverter's male and female
connectors must only be mated with the identical type and brand of the male and female connector.
IMPORTANT: IQ8 Series Microinverter includes both AC and DC connectors integrated into the bulkhead.
The AC port connects to the IQ Cable or the IQ Field Wireable Connector. The DC port has been
evaluated by TUV for intermateability with Stäubli-made MC4 connectors, whose cable coupler models
are "PV-KST4/...-UR, PV-KBT4/...-UR, PV-KBT4-EVO2/...-UR, and PV-KST4-EVO2/...-UR". The DC port of
the inverter must be mated with Stäubli-made MC4 connectors.

NOTE: IQ8 Series Microinverter will not begin producing power until the IQ Gateway is installed
and has detected all the microinverters at the site. The grid profile needs to be configured, and the
IQ Gateway must have propagated these settings to the microinverters. Refer to the
Installation and Operation
Earthing considerations
The microinverter has a Class II double-insulated rating, which includes ground fault protection (GFP).
Refer to local electrical codes and standards for earthing requirements of PV arrays and racking.
