Fortress Power Batteries Just Got Smarter

The Fortress Power Guardian Gateway and Dongle are smart gateway devices that connect your Fortress Power battery system to the cloud, enabling advanced remote monitoring and technical support. Once installed, they automatically detect all connected Fortress Power 48V batteries, allowing you to view detailed, real-time data such as State of Charge (SoC), voltage, current, and battery temperature — right down to the individual battery level.

By pairing them with the new Fortress Power Pro and Owner apps, users and installers gain access to a full suite of remote tools: firmware updates, live chat with technical support, support ticket submission, and secure data sharing with Fortress engineers. You can also monitor, manage, and support Fortress Power systems, anytime, anywhere.

Required for VPP and EnergyBroker Program Participation

To qualify for Fortress Power’s Virtual Power Plant (VPP) and EnergyBroker incentive programs, a Guardian device is required. The Guardian enables real-time communication between your battery system and utility partners, allowing your system to securely participate in scheduled grid events. Without it, systems are not eligible for performance-based incentives, bill credits, or participation in approved utility programs.
