Smart High-Voltage Energy Storage System


Whole-Home Backup Solution

The Fortress Power High-Voltage ESS consists of the Fortress Arrow high-voltage battery and Allure Energy Panel, combined with a high-voltage battery inverter to comprise a singular solution for smart, whole-home backup. 

The ESS allows for flexible, easy installation both indoors and outdoors thanks to its IP65 rating. The sealed, ultra-thin Arrow High Voltage (HV) Battery is a Lithium Iron Phosphate (LFP) product allowing for 6,000+ life cycles and protecting against dust, water, and humidity. It contains built-in active heating and cooling systems to accommodate hot and cold weather environments. The battery accommodates large and small configurations, capable of both series and parallel wiring. The form factor is thin and stackable, intended for both wall and floor mounting while improving transportation logistics and installation speed.  

The Allure Energy Panel combines critical features necessary for whole-home backup including 200A pass-through, grid transfer switch, and smart load management. Located between the home and the electric grid, the Allure contains an energy distribution panel for combining AC + DC coupled solar and battery inverters, EV chargers, and gas generators, as well as 12-load control circuits.
