NOTE: To ensure the best installation experience, Enphase is requiring that installers complete IQ8 training and certification online
to enable IQ8 system commissioning in the field
. For Enphase PV-certified installers, IQ8 training is an add-on qualification course and
for those who are non-certified installers you can access the training by
completing an online assessment through
Enphase University
.
We recommend having 100% of your installers take this certification course if you do Enphase installations.

Detailed Description
Enphase's newest IQ8 Microinverters are the industry’s first grid-forming microinverters with split-phase power conversion capability to convert DC power to AC power efficiently. The brain of the semiconductor-based microinverter is a proprietary application-specific integrated circuit (ASIC) that enables the microinverter to operate in grid-tied or off-grid modes. This chip is built in advanced 55nm technology with high speed digital logic and has super-fast response times to changing loads and grid events, alleviating constraints on battery sizing for home energy systems.
