Set up a new system | mc Help Center

Last modified: 2026-03-02

This topic is intended for users responsible for setting up a new system (= plant) in VCOM.

Caution

If your site has multiple power plant controllers (blue’Log XC data loggers or third-party PPCs) and you want to monitor each individually, each controller should be configured as a separate system, not as a subsystem. Otherwise, the performance ratio will not be calculated.

Example: A site has PV production across three rooftops, each with its own PPC. In this case, configure each rooftop in VCOM as a separate system.

To view the overall PR for the entire site, you can combine these individual systems into a virtual system in VCOM.

If you require further assistance, contact Support.

Recommendation: Prepare data

Before setting up a new system, we recommend collecting all the following information from designs, diagrams, manufacturer data sheets, and other relevant sources specific to your site and its components:

Exact address of your system
Responsible parties/contacts: names and email addresses of the owner, installer, operator, electrician, and invoice recipient (if relevant)
Date of installation of the entire system, of any subsystems, and of your measurement system (data logger or equivalent data source, such as PLC or API)
Total power output
Inverters and MPPTs: manufacturer, type, number of inverters, number of strings, modules per string, tilt and orientation in degrees
PV modules: manufacturer, type
Data logger: manufacturer, type, hardware serial number
Battery: rated capacity, inverter type and the number of busbars

Prerequisites

You belong to the user group administrator or operations.
You have in-depth knowledge about the specific components of your system.

Steps

1) Start the setup

To start setting up a new system, you have three options:

Either select New system in your Systems list.
Or at Portfolio level , go to Administration > Portfolio > New system.
Or at Portfolio level , go to Administration > Portfolio > Overview and select New system.

You arrive at the new system’s Site data page.

2) Enter site data and create system key

Define the type of system you want to create and enter general site data. See Site data for more information on your options here.
Select Continue

The basic framework of the system is now created, and a system key is assigned. You arrive at the new system’s System configuration page.

3) Complete the system configuration

The list on the system configuration page serves as a structured work plan to complete the system setup. We recommend following the steps from top to bottom. For each step, you will be redirected to the corresponding configuration page in the general System configuration menu. After you have completed a step, return to this list to continue with the next one. You can also exit the system configuration at any time and return to it at system level , under System configuration > System > System configuration.

Icons and warning messages indicate whether there is a problem or everything is OK. If a warning message does not apply to your system, you can choose to Ignore it, and the step is done. At the end of the setup, all items in the list should be OK.

The individual steps differ depending on the system type:

For physical systems

See System configuration for physical systems.

For virtual systems

See System configuration for virtual systems.
