EN4 Bulkhead Microinverters
IMPORTANT
: Enphase IQ Series EN4 Microinverters include AC and DC connectors integrated into the microinverter
bulkhead. The AC port of the Enphase EN4 bulkhead connects to an Enphase Q Cable or Enphase Field Wireable
Connector. The DC port of the EN4 bulkhead has been evaluated by UL for intermatability with TE PV4-S
SOLARLOK connectors, and several other connectors, that have been Listed and identified for intermatability with the
Enphase EN4 bulkhead connector, which allows you to plug them directly into the IQ7 Series microinverter with EN4
bulkhead. For other connector combinations, Enphase bulkhead adapters are required.
An IQ Envoy is required to monitor performance of the IQ Microinverters. The Q Accessories work only with Enphase
IQ Series Microinverters.
