System configuration for physical systems

Last modified: 2026-03-06

Find the configuration workflow at the physical system’s system level > System configuration > System > System configuration.

Site data and photo

Site data

If you just set up the new system, you already entered its site data, and you do not have to do anything else here. See also Site data.

Site photo

If a Site photo is missing, you can upload a photo here, or choose to Ignore this warning in order to complete this step.

Responsibilities

Assign responsibilities for certain system topics. See Responsibilities.

Technical data

If there is No subsystem configured, the system’s Installed power can not be retrieved.

Set up subsystems, to specify the system’s technical components, such as inverters, modules, or batteries, and to define a default system plan. See Subsystems.

Data logger

If The measuring system has not been determined, no data is imported into VCOM.

Add a data source or a data logger by following the steps under Data sources / data logger. For adding a blue’Log XM/XC, go directly to blue'Log XM/XC data logger.

Once you have added the data logger, close the configuration window and reopen it. The data logger and all connected devices now appear under System configuration > Data sources > Data logger overview and the corresponding data points are imported.

Also check the other configuration options under System configuration > Data sources > [Data source name]:

• To ensure alarms work properly, assign the correct scale factor in kW to each subsystem under Current sensors via Details. Or under Inverter.

  

• Configure Other devices. See also Other devices .

• You can configure error states (0 or 1), e.g. fault messages, under Digital signals. If you have not manually set the error state, it will be displayed as 0.

• It is also possible to configure string inverters and string boxes (string combiner boxes) if these are included in your imported data.

  • Activate or deactivate single inverter inputs under String inverter.

  • Manage string combiner boxes under Stringbox.

Other

Terms

With terms, you define formulas to calculate your system’s basic or user-defined data points. The term E_Z_EVU (Actual generated energy, formerly: PV yield counter) is mandatory for your system setup. Without it, basic calculation can not be performed and most of the charts can not be displayed.

To configure terms, see Terms.

Report

legacy only If displayed, the report item redirects you only to the legacy reporting module.

To directly configure new reports, see Reporting.

Meter management

When setting up the basic framework for your system, a meter of the type Solar energy meter is automatically added to your system, and you can edit its settings. See Meter.

If The meter reading at installation is 0, you should verify this. You can also choose to Ignore this note if the reading is correct in order to complete this step.

Standard alarms

Before setting up your alarms, ensure no issues appear under System structure. Then set up your alarms and alarm notifications as described under Smart alarms.

System structure

If there are any issues with your configuration, they will be displayed in this section.

If there are no system configuration issues anymore, green check marks appear next to all items in the System configuration list.
