The Fortress Power Guardian Gateway is the essential monitoring backbone for any Fortress Power battery installation. By connecting the entire battery system to the cloud, the Guardian transforms a standalone energy storage deployment into a fully connected, remotely manageable, and professionally supported system that installers and homeowners can monitor and control from any device, anywhere in the world.

Mounted on the DIN rail inside the DuraRack, FlexTower, or any compatible enclosure, the Guardian's five status LEDs provide at-a-glance system health confirmation covering power status, cloud connection, Bluetooth/Wi-Fi connectivity, serial battery communication, and error signals — ensuring any issue is immediately visible without requiring access to the app. Its compact 0.8 lb form factor and DIN rail mount make installation clean, fast, and completely unobtrusive within any enclosure.

Supporting MODBUS/TCP, MODBUS/RTU, and CAN 2.0 communication protocols, the Guardian is designed to communicate with the full range of Fortress Power battery systems with maximum compatibility and reliability. Available on both iOS and Android, the Guardian companion app delivers professional-grade energy storage management in the palm of your hand.
