IQ Combiner 5/5C Quick Install Guide 44
NOTE: If the installer wants generator integration or if the
Main Panel Upgrade avoidance feature (applicable in partial
home back congurations and grid-tied PV only systems) is
enabled, the Consumption CTs need to be installed between the
IQSystemController3/3G and the main panel in order to monitor
and control the current back-fed from the IQSystemController to
the main panel. Installing the CTs at this location would impact the
Aggregate power export limiting (PEL) feature. For further details
refer CT Installation Guidelines Tech Brief.
