Scenario 3a

Partial Home backup with Sunlight
Backup and generator
This is the preferred configuration for partial home backup using only
IQ8 PV i.e., Sunlight Backup. A generator can be integrated with IQ System
Controller 3G 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 Series
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 configuration can only be supported with IQ8 Series Microinverters.
Note: The System Shutdown Switch is not used for IQ6, IQ7, and M Series
systems. Referto the System Shutdown wiring section
Additional wiring and components are required when integrating generators.
Refer to the Generator integration page for technical briefs and guides
