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
After 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 (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 as with 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 wires connect from the PV module directly to the co-
located microinverter, eliminating the risk of personnel exposure to dangerously high DC voltage.
