There are no special instructions for microinverters with integrated MC4 connectors. Please follow the same installation practices as outlined in the Enphase installation manual.

No, there is no price difference between the microinverters that have integrated MC4 connectors and those that use adapter cables.

It doesn't use an external bulkhead adapter, so the overall cable is a bit less. However, module leads are typically 4 to 6 feet long, so the impact is minimal.

• Installers can currently deploy Enphase solutions for three-phase electrical service customers utilizing the Enphase IQ7+, Q Cable and IQ Commercial Gateway. This provides a 208V three-phase solar PV solution compatible with 208V three-phase electrical main service panels and 480V electrical main service panels when the PV is connected to the low side of a 480-208 transformer. For locations requiring loss of phase detection. The Enphase Three Phase Network Protection Relay, which includes the IQ Commercial Gateway, offers loss of phase detection for sites that need it.

Yes, all microinverters will eventually have integrated MC4 connectors. We are gradually transitioning each inverter in a phased manner.

• Yes, all system owners will utilize the same app, irrespective of system type. Owners with multiple systems can access all their Enphase systems from a single login to the Enphase App.
