Overview

In this configuration, the Enphase Energy System provides all-day backup for essential loads using IQ6 or IQ7 Series Microinverters and IQ Batteries. To maintain stability, IQ PV continuous power cannot be greater than 150% of the IQ Battery continuous power. 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 reject high power loads or shed excess PV.

Important tips

• Backup systems with IQ7 Series Microinverters require IQ Gateway software version 6 or later. If an update is needed, it will be automatically applied during the commissioning process.

• Backup systems with IQ7 Series Microinverters can use IQ Combiner 3C or IQ Combiner 4C.

• Home Essentials Backup systems support up to four essential load circuits. This requires the installation of two IQ Load Controllers to control all four load circuits.

• Home Essentials Backup systems with IQ7 Series Microinverters require the use of an IQ System Controller 1 or IQ System Controller 2.

• Full Energy Independence backup systems with IQ6 or IQ7 Series Microinverters require a battery array 150% the size of the PV array. A smaller battery array will require the PV array to be split.
