Basic info

Item in the Portlet center
Description	The Alarms portlet gives you a complete overview of all the alarms, at both the portfolio and system level. You can decide which columns to display and in what order, filter alarms according to various criteria, view the details of each alarm, and create tickets based on the alarms.
Prerequisites	Configure Smart alarms to view data.
Portlet properties	Portfolio portlet: The portlet can be added at the Portfolio Level .System portlet: The portlet can be added at the SYSTEM LEVEL . Dynamic portlet: The portlet is updated when you select a different system name from the systems list.
Further details	📗 Tip We recommend giving the Alarms portlet sufficient space since it contains many functionalities, as illustrated in the overview. portfolio level To view all alarms in your portfolio, navigate to the Control room > Portlet center on the top bar > Select the Alarms portlet. portfolio level To filter alarms by system at the portfolio level, select a system from the sidebar list. The Alarms portlet then only displays the alarms of that system. system level Navigate to the Cockpit of a specific system. The Smart alarms tab at the system level contains the Alarms portlet by default.

Overview of the portlet

	Name	Details
1	Ticket actions	Tick multiple checkboxes to: Group alarms into a ticket Close alarms See also Ticket system.
2	Further actions	Create ticket Close alarm Open Alarm details as a chart or an extended overview of the alarm. Mute affected component More options if not all options are visible next to the alarms.
3	Alarm level	Does the alarm affect the overall system or just a device? System Data logger Device (inverter, sensor, power plant controller, etc.)
4	Alarm type	See What types of alarms are there?
5	Affected devices	Number of affected devices or designation of the affected device.
6	Affected power	Percentage of system power affected by the incident. You can also display the affected power in Watts via the portlet settings.
7	Losses	Yield loss due to the incident in kWh. See Yield loss calculation.

Alarm details

To view further details about an alarm, select Open alarm details. Here you can see the related data logger and any related tickets. Depending on the alarm type, system configuration, and installed components, you can also see additional helpful information.

Affected system power

The affected system power means the percentage of overall system power affected by an incident.

Details about affected system power

The following formula is used:

Affected power = (Actual power in kW / Expected power in kW) * (Component installed power / Total installed power) * 100

Example

If 1 of of 10 identical inverters produces 10% less power than expected, the affected power of the inverter (= component) is 10%. Since this inverter represents 10% of the total system power, the affected system power is 1%.

Measured deviation

Actual energy (from the latest incident) vs. Expected energy (based on the calculation/simulation method you configured for misproduction alarms). Misproduction alarms only.

Chart and/or heatmap

Where relevant, a chart is displayed in a tab to visualize the alarm and help identify its root cause. Charts are not displayed for user-defined alarms.

Device events

The Device events tab shows device events of the affected component or system if the following conditions are met:

Device events are available. See Device events portlet.
The device event occurs when the alarm is open.

Incidents

The Incidents tab shows relevant incidents, in this case, a yield loss. Hover over the Details column to view the details of the measured deviation.

Example

This example shows a misproduction alarm triggered at the system level.

The misproduction affects 62% of the overall system power. Based on the machine learning and physical simulations, it can be interpreted as a 62% deviation from normal behavior.

The chart displayed in the Solar power tab shows the actual power (red line) compared to the irradiance measured by a sensor (yellow line). The shaded red area shows the target range configured for the system.
