Charts

Last modified: 12 Feb 2025

You can visualize the values currently being measured by your devices under Cockpit > Charts. Measurements are displayed in 1-minute interval values. This feature can be used e.g. for troubleshooting purposes. Here is an overview of the functions:

Item	Name	Details
1	Value selection	The active device category is underlined in blue. Example: “Inverters 1/2” means that two inverters are configured and you have selected one to display. Select Select all to select all values for a category.
2	Configured devices	Place a checkmark next to the device(s) you want to see in the chart.
3	Values	Place a checkmark next to the values you want to view. Multiple selections are possible. Click on Select all to select all values for a category.
4	Chart	All devices and values you have selected are displayed as a chart which can display many different parameters. You can zoom in and out of the charts and display a wide range of periods, e.g. from 6 months to 5 minutes.
5	Cursor	Move the cursor over the chart to display the values at each point for each device.
6	Realtime values	Activate the toggle to display real-time values, if any are available. See Real-time values.
7	Download chart	Download a CSV file of your chart

Note

Cos phi (also known as cos φ or power factor) is a calculated value.

When multiple real meters are combined into a virtual meter, the cos phi value is calculated based on the following formula:

Cosine of phi equals the cosine of the arctangent of Q divided by P, multiplied by the sign of Q — cos phi formula

Variables

P is the measured active power sum of all phases
Q is the measured reactive power sum of all phases
tan^-1 represents the arctangent function
sgn(Q) represents the sign of Q, so if Q is underexcited it is -1, otherwise it is 1

Any measured values from the individual meters are ignored.
