Cellwatch displays alarm levels for individual jars along with their history graph for easy comparison of actual readings and programmed alarm levels. With just a few clicks, you can now visualize how the cell is trending over time compared to the alarm levels configured for that jar. Easily view an entire string’s performance in just a few seconds.

Cellwatch provides an alarm management tool to simplify the process of managing alarms. The data manager gives you controls to search, sort and filter alarms making it easy to identify and isolate battery failures. You can also generate a report, allowing for quick and proactive response to battery conditions.

Cellwatch allows you to simultaneously view two measurement parameters for easier and more accurate analysis of battery health, or for pinpointing the cuase of a failing battery. This view is showing voltage and ohmic value.

This view lets you see how well the UPS charger/rectifier is working.

You can view all history data for all battery configurations available in Cellwatch. Graphing functions provide quick views of a battery’s performance over its entire life cycle, and allow you to quickly select, isolate and zoom in for easy evaluation of a combination of cells/strings or batteries.

Cellwatch automatically sets ohmic alarm levels in minutes for all new strings being monitored, or on a string-by-string basis for aging battery systems. The auto set ohmic alarms function ensures proper ohmic alarm setting, improving set-up for batteries with inter-cell and inter-tier links that have varying ohmic measurements. This feature also eliminates the risk for human error and saves a significant amount of time for large battery systems.

Cellwatch provides data on temperature of the batteries. If they are too hot, battery life is compromised. If they are too cold, then performance is compromised.

Cellwatch provides a detailed view of all cells under load so you can verify performance of each individual cell/jar under load.
