SAFETY AND HANDLING INSTRUCTIONS
Read this entire document before installing or operating the Backup Interface (also referred to as BUI). Failure to do so or to follow any of the
•
instructions or warnings in this document can result in electrical shock, serious injury, or death, or may damage the Backup Interface and
other property, it can also lead to warranty void.
Do not discard this document! After installation, keep it adjacent to the Backup Interface for future reference!
•
Before operating the Backup Interface and inverter, ensure that they are properly grounded. The Backup Interface and inverter must be
•
connected to a grounded, metal, permanent wiring system, or an equipment-grounding conductor must be run with the circuit conductors
and connected to the equipment grounding terminal or lead.
Opening the Backup Interface and repairing or testing under power must be performed only by qualified service personnel familiar with the
•
Backup Interface.
WARNING
!
The backup systems generate power to the home when the grid is off or when the main circuit breaker is also OFF. Please make sure to
attach the warning sticker (of Dual Supply warning) in a visible place at the main circuit cabinet. For additional safety, we recommend
installing an external shutdown press button to make sure the Inverter is also turned off when the main circuit breaker is off.
For installation instructions please refer to the Inverter installation guide.

BACKUP POWER DESIGN GUIDE
The design of backup power is limited only to the SolarEdge Home Hub Inverter Single Phase, operating as a backup Inverter,
and the availability of a standard code three phase grid (not a generator). The backup system cannot operate as an OFF-grid-
only system.
The following design configuration options are available:
Full House Backup (FHB) – In this configuration, all home loads can operate in backup mode and are limited to the Inverter
•
power during Backup.
Partial House Backup (PHB) - In this configuration, only part of the home loads can operate in backup mode and are limited
•
to the Inverter power during Backup.
For detailed design and configuration options, refer to:
