Overview
In this configuration, the Enphase Energy System provides all-day backup for essential loads using M Series Microinverters and IQ Batteries. To maintain stability, no greater than 150% of the IQ Battery continuous power capacity (in IQ PV capacity) can be wired into IQ System Controller. This use case is best when the Enphase Energy System is configured to provide backup to a few pre-selected, essential load circuits. Up to two IQ Load Controllers are strongly recommended to shed high power loads.
