How the Enphase IQ8 Series Microinverters 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 the maximum power
available from each PV module is produced 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 IQ Gateway and provide an internet connection through a broadband router or
modem, the IQ8 Series Microinverters automatically begin reporting to the Enphase Installer Platform.
Enphase Installer Platform presents current and historical system performance trends and informs you of
PV system status.
Optimal reliability
Microinverter systems are inherently more reliable than conventional string 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
and much higher microinverter temperatures.
Ease of design
PV systems using Enphase microinverters are very simple to design and install. 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.
