CELLGUARD - Wireless Battery Monitoring System (BMS)

Get remote access to the information you need to proactively maintain your stationary power systems and avoid costly downtime. With solid noise immunity, the CELLGUARD™ Wireless Battery Monitoring System is suited for applications including power utilities, data centers, telecommunications systems, and DC systems with filtered AC electrical ripple.

WIRELESS COMMUNICATION
Installation cost and time are reduced with the system’s wireless communication capabilities which enable all hardware to communicate to the Base controller free of cabling.

ACCURATE CONDUCTANCE MONITORING
Conductance-based monitoring technology provides the most accurate, efficient, and non-invasive method possible for monitoring a battery’s state-of-health.

ADVANCED HARDWARE
Comprised of a Base Coordinator Unit (BCU) and single-battery sensor modules, the system provides both visual and digital battery state-of-health and is capable of monitoring up to 16 battery strings, up to 300 sensors per string, and up to 600 sensors per BCU (irrespective of how they are divided by strings).

CUTTING-EDGE WEB INTERFACE
The highly intuitive CONVERGE™ web interface enables rapid, confident installation, remote system monitoring, alarm threshold configuration, rock-solid reporting (including granular discharge data gathering), and critical over-the-air sensor firmware updates.
