The Enphase Ac Combiner Box With Enphase Envoy-S; How The Enphase Microinverter System Works - enphase AC Combiner Box Installation Manual

The Enphase AC Combiner Box with Enphase Envoy-S

The Enphase AC Combiner Box™ with Enphase Envoy-S Metered™ consolidates interconnection equipment
into a single enclosure and streamlines PV installations by providing a consistent, pre-wired solution for
residential applications. The included Envoy-S provides integrated revenue-grade PV production metering
(ANSI C12.20 +/- 0.5%) and optional consumption monitoring (+/- 2.5%).
The AC Combiner Box is an outdoor-rated, NRTL-certified NEMA type 3R, polycarbonate enclosure
containing an Enphase Envoy-S, circuit breakers, and wiring for Envoy-S connections. The AC Combiner Box
combines up to three AC branch circuits of Enphase Microinverters.
The Envoy-S Metered operates as a gateway between the Enphase Microinverters and the Enphase
Enlighten™ web-based monitoring and analysis software. The Envoy-S monitors the microinverters that are
connected to the PV modules. It collects energy and performance data from the microinverters over on-site
AC power lines, and it forwards that data to Enlighten, via the Internet, for statistical reporting.

How the Enphase Microinverter System Works

The Enphase Microinverter converts the DC output of the PV module into grid-compliant AC power. In
addition to performing the DC to AC conversion, it maximizes energy production by using a sophisticated
Maximum Power Point Tracking (MPPT) algorithm. This integrated system maximizes energy harvest,
increases system reliability, and simplifies design, installation and management.
The Enphase Enlighten web-based monitoring and analysis software analyzes the data collected by each
communicating microinverter and automatically detects any shortfall in energy production, identifies
possible causes, and suggests solutions. Enlighten constantly monitors every Enphase Microinverter
connected to the Envoy-S and is essential for system monitoring and troubleshooting.
Enlighten provides a wide
range of information on
system performance. You
can even access Enlighten on
your mobile device and view
current performance
information wherever you are.
