2.1 How the AC Module Works
The Enphase Microinverter maximizes energy production by using a sophisticated Maximum Power Point
Tracking (MPPT) algorithm. Each Enphase Microinverter is individually connected 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.
2.2 System Monitoring
Once you install the Enphase Envoy-S or Enphase IQ Combiner 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.
2.3 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 IQ7 and IQ7+
Microinverters are designed to operate at full power at ambient temperatures as high as 65
℃
(149 F).
2.4 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. 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.
