NEW Essential Backup Load Unit: Essential Backup Power Made Easy

The Fronius Essential Backup Load Unit (EBLU) is designed to handle your backup needs automatically while providing the most optimal runtime for your home appliances. The Essential Backup Load Unit works both on grid and off grid to provide up to 50A of continuous current to your home loads. With a properly sized battery and simple load calculations, the Essential Backup Load Unit can potentially power your essentials for hours or even days.

When an outage occurs, the EBLU gives homeowners peace of mind by using PV or stored energy to keep essential loads powered, such as lights, refrigerators, routers, and emergency appliances like medical equipment or sump pumps.

How it works

The Fronius Essential Backup Load Unit connects to a breaker within your main distribution panel or fuse box after your first home disconnect. The Essential Backup Load Unit and Fronius GEN24 continually monitor your grid connection using the Fronius Smart Meter WR. When a power outage occurs, your non-essential appliances remain connected to the utility grid. The Essential Backup Load Unit transitions your essential appliances to operating directly on Solar and stored battery energy.
