How the Microinverter Works
The Enphase Microinverter maximizes energy production from your photovoltaic (PV) array. Each
Enphase Microinverter is individually connected to one PV module in your array. This unique
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 utility
grid 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 NEMA 6
environmental enclosure rating standard:
NEMA 6 rating definition: Indoor or outdoor use primarily to provide a degree of
protection against hose-directed water, the entry of water during occasional temporary
submersion at a limited depth, and damage from external ice formation.
NOTE: To ensure optimal reliability and to meet warranty requirements, the Enphase
Microinverter must be installed according to the instructions in this manual.
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 PV racking, 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.
