Fortress Power Guardian Battery Monitoring Gateway
The Guardian is the monitoring gateway for a Fortress Power battery system, reporting state of charge, voltage, current, and temperature for each connected battery individually over MODBUS, CAN, or built-in Wi-Fi.
It's the hardware Fortress Power requires for Virtual Power Plant program enrollment, and it feeds live system data to the Fortress Power Pro and Owner mobile apps.
-
Per-Battery Monitoring: Tracks state of charge, voltage, current, and temperature on each connected battery individually, not just at the system level.
-
Wired & Wireless Connectivity: 1x MODBUS/TCP, 2x MODBUS/RTU, and 2x CAN 2.0 ports, plus built-in 2.4GHz Wi-Fi.
-
Fortress Power App Access: Feeds live system data to the Fortress Power Pro and Owner apps for remote monitoring.
-
VPP-Ready: Required hardware for enrolling a compatible Fortress Power system in Virtual Power Plant programs, where available.
-
Compact DIN-Rail Mount: 7.25" x 6" x 1.25" and 0.8 lb — mounts inside the electrical enclosure alongside the rest of the system.
