M215 Installation and Operation

How the Microinverter Works

The Enphase Microinverter maximises energy production from your photovoltaic (PV) array. Each Enphase
Microinverter is individually connected to one PV module in your array. This configuration means that an
individual Maximum Peak Power Point Tracker (MPPT) controls each PV module. This ensures that the
maximum power available from each PV module is exported to the electricity network regardless of the
performance of the other PV modules in the array. That is, although individual PV modules in the array may be
affected by shading, soiling, orientation, or PV module mismatch, the Enphase Microinverter ensures top
performance for its associated PV module. The result is maximum energy production from your PV system.

System Monitoring

Once you install the Envoy Communications Gateway and provide an Ethernet connection to your broadband
router or modem, the Enphase Microinverters automatically begin reporting to the Enphase Enlighten web
server. The Enlighten software presents current and historical system performance trends, and it informs you of
PV system status.

Optimal Reliability

Microinverter systems are inherently more reliable than traditional inverters. The distributed nature of a
microinverter system ensures that there is no single point of system failure in the PV system. Enphase
Microinverters are designed to operate at full power at ambient temperatures as high as 65° C (150° F). The
microinverter housing is designed for outdoor installation and complies with the IP67 regulation:
IP67 protective factor definition: Entirely protected against the effects of dust and immersion.

Ease of Design

PV systems using Enphase Microinverters are very simple to design and install. You will not need string
calculations, and you can install individual PV modules in any combination of PV module quantity, type, age and
orientation. You won't need to install cumbersome traditional inverters. Each microinverter quickly mounts on
the mounting rail, directly beneath each PV module. Low voltage DC wires connect from the PV module directly
to the co-located microinverter, eliminating the risk of personnel exposure to dangerously high DC voltage.
