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:

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.

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.
