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 Envoy-S 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.
