ABOUT INALA
Inala’s SAM2 is a new concept of remote power management that allows the
operator to fully manage and maintain its network infrastructure remotely.
It provides the ability to monitor all power related issues
including but not limited to:
•
•
•
•
•
•
•
Generator control
Battery Management
Utility Grid Power Management
DC Reduced Energy Cooling (REC)
Fuel Management - Fuel levels and accurate consumption
Highlights any anomalies with excessive usage (theft!!)
The ability to identify problematic sites before deploying field staff Avoids unnecessary call outs
