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 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
(149°F).
Ease of design
PV systems using Enphase microinverters are very simple to design and install. You will not need to
perform cumbersome string sizing calculations like conventional string 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
cables connect from the PV module directly to the co-located microinverter, eliminating the risk of
personnel exposure to dangerously high DC voltage.
