In the whole home (main load panel) backup configuration, IQ System Controller is installed on the line side of the main
load panels rated up to 200 A. This allows a properly sized Enphase Energy System to provide power to all loads in the
main load panel in the event of a grid outage. In this configuration, the IQ System Controller can be configured with a
main breaker to act as the service disconnecting means. The PV system can be connected to the IQ System Controller
on a dedicated breaker or to the main load panel. This configuration typically supports larger PV and storage system
sizes and may allow for avoiding expensive utility service and/or main service panel upgrades.
The above configuration can also work with a genset connected to IQ System Controller with or without IQ Battery. The
two images explain the connection configuration.
