Collection: Microinverter Accessories

The accessories for wiring microinverters: Hoymiles Flex-S3 extension and trunk connectors for the HMS series with their EN2560C termination caps, APSystems end caps for the AC bus of the DS3 and 5C series, and the Enphase three-phase external relay for the IQ Series as a phase coupler.

With microinverters the AC bus is the installation: every module plugs into a backbone and every open end needs the maker's cap, or the IP rating of the connection is not guaranteed and water gets into the connector.

The accessories are not interchangeable between brands: Hoymiles, APSystems and Enphase use different connectors and pitches, so check the exact series of microinverter fitted.
