Enphase Energy System PV solar + storage – Whole home backup
configuration
In the whole home (main load panel) backup configuration, the 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 interconnected to the IQ System Controller on a
dedicated breaker or may be interconnected 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 generator connected to the IQ System Controller with
or without an IQ Battery. The following two images explain the connection configuration.
