How the Enphase IQ Series Microinverters work
The Enphase microinverter maximizes energy production by using a sophisticated maximum power
point tracking (MPPT) algorithm. Each 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 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 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 IQ Microinverters automatically begin reporting to the Enphase Installer Portal. The
Enphase Installer Portal 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 60°C (140°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.
