How the Enphase IQ Series Micros Work
The Enphase Microinverter maximizes energy production by using a sophisticated Maximum Power Point
Tracking (MPPT) algorithm. Each Enphase Microinverter individually connects to one PV module in your
array. This configuration enables an individual MPPT to control each PV module, ensuring that 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. While an individual PV module in the array may be affected by shading,
soiling, orientation, or PV module mismatch, each Enphase Microinverter ensures top performance for its
associated PV module.
System Monitoring
Once you install the Enphase IQ Envoy and provide an internet connection through a broadband router or
modem, the Enphase IQ Microinverters automatically begin reporting to Enlighten. Enlighten presents
current and historical system performance trends and 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).
Ease of Design
PV systems using Enphase Microinverters are very simple to design and install. You will not need string
calculations or cumbersome traditional inverters. You can install individual PV modules in any
combination of PV module quantity, type, age and orientation. 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.
