Fortress Power Unveils New High-Voltage, All-in-One Residential Battery


Introducing the Avalon High Voltage Energy Storage System

Fortress Power’s Avalon High Voltage Energy Storage System combines a hybrid inverter, high-voltage battery, and a smart energy panel in an all-in-one, whole-home backup system.

Fortress Power Enters the Residential High-Voltage Energy Storage Market

US-based Fortress Power has announced its entry into the high-voltage energy storage residential market. It marked this milestone with the installation of its first residential Avalon System in late December.

Key Features of the Avalon HV ESS System

The Avalon HV ESS system features a smart energy panel, customizable battery stack, and inverter. The system works inside and outside and is scalable up from 14.4 kWh to 176 kWh. It can be DC- or AC-coupled, with 200 A pass-through.

Operating at 200 V to 300 V at the DC terminal, the Avalon System closely matches PV array voltage, reducing the need for DC to DC conversion which, according to the manufacturer, enhances overall operational efficiency by approximately from 6 to 8%. 

The system includes a 7.6 kW or 11.4 kW inverter. It has four MPPTs with a voltage range of 80 V to 520 V and maximum input current per string of 16 A.

Smart Energy Panel for Whole Home Backup

The Avalon Smart Energy Panel manages large loads in the house to stop the inverter from tripping. It can intelligently manage up to twelve different 120 V circuits, six 240 V circuits, or any combination, providing flexible whole home backup without a dedicated emergency power panel.

Simplified Design for Easy Integration

With the integrated smart load panel, pre-installed AC coupling circuit, 200 A pass-through and straightforward EV charger installation, the Avalon System reduces the need for extra components, such as back up panel, AC combiner, separate smart load panel, bypass, and other, the manufacturer says.

Durability and Warranty

Avalon boast a cycle life of more than 8,000 cycles and comes with a 10-year warranty. The system is based on tier 1 automotive grade lithium iron phosphate (LFP) battery cells.

Potential Revenue for Homeowners

Furthermore, for homeowners, Avalon could be turned into a source of revenue through the company’s EnergyBroker program by selling energy into wholesale markets or to extra energy.

Contribution to a More Resilient Power Grid

“This helps achieve a shorter payback period while contributing to a more resilient and efficient power grid,” Fortress Power says.
