Which set correctly lists the three core components of an Enphase PV system?

• A. Enlighten, Envoy, Microinverter
• B. Enlighten, Microinverter, Inverter
• C. Envoy, Microinverter, Combiner
• D. Enlighten, Envoy, Installer Toolkit

Answer: (A)

The three parts that define an Enphase PV system are Enlighten, Envoy, and Microinverter. Enlighten is the cloud-based monitoring platform that lets you view system performance, alerts, and analytics for all modules. Envoy acts as the communications gateway, collecting data from the microinverters and sending it to Enlighten, while also providing a local network connection for setup and status checks. The Microinverter is the device attached to each solar module that converts DC to AC at the module level, enabling individual module monitoring and independent operation.

The other options mix in components that aren’t part of the core Enphase architecture. A general inverter isn’t used in Enphase systems, since Enphase relies on microinverters. A combiner box is a wiring accessory rather than a fundamental system component, and the Installer Toolkit is a software tool for installers, not a hardware element of the PV system. So Enlighten, Envoy, and Microinverter together correctly identify the essential elements.
