Guardian Gateway
Fortress Power Batteries Just Got Smarter
The Fortress Power Guardian Gateway is a smart gateway device that connects your Fortress Power battery system to the cloud, enabling advanced remote monitoring and technical support. Once installed, the Guardian Gateway automatically detects 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 the Guardian Gateway with the Fortress Power mobile app, 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 complete warranty registrations, apply for EnergyBroker programs and track system performance, all from a single, easy-to-use platform.
