Alarm-to-Task Operations Across a Multi-Site Solar Portfolio
An O&M team monitoring 12 solar sites with mixed inverter brands cut alarm noise and closed production losses faster from a single panel.
Scale
12 sites · ~28 MWp · 180+ inverters
Devices
Huawei, Sungrow, Solis; IEC-104 RTU; weather station
Starting point
Vendor portals were used separately; alarms were lost in email and string-level losses took hours to locate.
Solution applied
Ranaliz portfolio dashboard, custom alarm rules, task management and MPPT/string heatmaps were deployed.

Recurring inverter alarms
“Seeing every brand in one panel sped up dispatching the right crew before anyone drove to site.”
Methodology
PR used declared plant capacity and clean production hours. Alarm-to-task time used platform event timestamps.
