Partial Home backup with
Sunlight Backup
This is the preferred conguration for partial home backup using only
IQ8 PV i.e., Sunlight Backup. IQ Battery can be integrated with IQ System
Controller 3 based on the homeowner’s needs.
It is recommended that installers use two IQ Load Controllers for
load control to ensure seamless backup of essential loads using
IQ8 Microinverters. At least one IQ Load Controller is required to
successfully commission a Sunlight Backup system.
Do not install a Sunlight Backup system for a whole home backup
scenario.
This conguration can only be supported with IQ8 Series Microinverters.
