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. The generator or IQ Battery can be

integrated with IQ System Controller 2 based on the homeowner's

needs.

It is recommended that installers use two IQ Load Controllers for

load shedding to ensure seamless back up 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 configuration can only be supported with IQ8

Microinverters.

Note: The System Shutdown Switch is not used for IQ6, IQ7, and M Series

systems. Refer to 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
