Alber
Monitoring System
The matching Liebert EXL Battery Cabinet has space for an Alber battery monitoring system. The battery
monitoring system can be factory-installed or field-installed later.
The Alber Battery Monitor by Vertiv continuously checks all critical battery parameters, such as cell voltage,
overall string voltage, current and temperature. Automatic periodic tests of internal resistance of each battery
will verify the battery's operating integrity. Capabilities include automatic internal patented DC resistance tests
and trend analysis, providing the ability to analyze performance, aid in troubleshooting and detect failing cells
before they fail.
