Are there any special installation instructions for microinverters with integrated MC4 connectors?
There are no special instructions for microinverters with integrated MC4 connectors. Please follow the same installation practices as outlined in the Enphase installation manual.
Is there a cost difference between the two microinverter types?
No, there is no price difference between the microinverters that have integrated MC4 connectors and those that use adapter cables.
Can the installer reduce the cable slack to connect to the solar panel lead cable?
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.
Will microinverters requiring MC4 adapter cables be phased out completely?
Yes, all microinverters will eventually have integrated MC4 connectors. We are gradually transitioning each inverter in a phased manner.
