Daylight systems may be configured for either whole-home backup or backup of selected critical loads depending on the system design and equipment installed at your home.
Critical-load backup supplies selected circuits or equipment during an outage.
Whole-home backup allows the backup system to support your home’s electrical system more broadly, subject to the system’s available power and energy capacity.
Daylight currently allows whole-home backup on eligible systems where a critical-load panel has not already been installed.
Your home’s final system design determines how your backup system is configured.
Even with whole-home backup, your battery has finite power and storage capacity. Large electrical loads can significantly reduce how long backup power lasts.
