In this configuration, the Enphase Energy System provides backup using IQ8 Series Microinverters when the sun is shining. The system does not include any IQ Batteries. The system can support PV branch circuits rated for up to 64 A continuous current output.
The IQ System Controller 2 is installed on the load side of an existing main load panel. This configuration must be used with an essential loads solution, consisting of:
An off-the-shelf panel with a maximum of four 240 V L-L or eight 120 V L-N, essential load circuits that are backed up by the system. An additional 120 V L-N breaker is required to power each IQ Load Controller.
Either one or two IQ Load Controllers, each enabling fine-grained, circuit-level control of each 240 V or a group of two 120 V essential load circuits.
Using this configuration for backing up an entire home will lead to poor customer experience and is not a use case supported by Enphase.
