Avalon Smart Energy Panel
The Fortress Power Avalon Smart Energy Panel is the easiest and least
expensive way to backup a whole home.
- No separate critical load panel needed, or add more circuits in critical load
panel with load management. The Avalon Smart Energy Panel intelligently
manages large loads in the house to stop the inverter from tripping o .
- No automatic transfer switch (ATS) needed. Safely connect and operate
a gas generator without the need for a separate transfer switch.
- No separate AC combiner box needed. AC couple an existing PV installation
or add an EV charger directly to the Avalon Smart Energy Panel.
- LED indicator and LCD screen for system status.

Fortress Power Mobile App
- Simple: One App for the entire energy storage system! The Fortress Power App uses straightforward descriptions
and images to help you set-up and operate your energy storage system. We’ve simplified the process so that you
can have quicker installs, fewer callbacks, and fewer confused customers.
- Visual: No more hard-to-interpret screens of confusing numbers. The Fortress Power App presents users with an
intuitive visualization of the flow of power through their system.
- Configurable: Take control of your energy usage during a blackout. Automatically shed loads when your ba ery gets
low to preserve power for other critical devices. Automatically turn them back on when your ba ery is charged back
up. The most powerful way yet to Secure Your Energy.
