Set up a KOSTAL Piko inverter

General tips

Serial number: Have the data source (data logger, etc.) serial number on hand. When entering the serial number, pay attention to uppercase and lowercase letters and empty spaces.
Name: In most cases, the data source name can be freely selected. For recommendations, see our Naming guideline.
Multiple data sources: If possible, use data sources that support the same measuring interval or align the intervals if possible. Otherwise, minor features may not work properly. See also Measuring interval.
Automatic device creation: This will automatically create new devices in the system, such as inverters or batteries, as soon as their data is included in a new import file. It is not possible to manually create these devices. In rare exceptional cases, for example, if the devices are already included in another system, you do not need to tick this checkbox.
Connection test: If possible, perform a connection test once you have completed the configuration in both VCOM and the data source.

Data loggers only

For data loggers, update the firmware to the latest version prior to configuration.
For data loggers, any import that uses FTP can also use SFTP. The access data, such as the FTP server address, user name, and password remain identical. Only the port changes from port 21 (FTP) to port 2222 (SFTP).

APIs only

If you experience import issues with the API, please contact the respective API provider first.
Each day at midnight, VCOM checks for complete data and requests data from the past 7 days. If there are no limitations from the API and the data is available, the gaps will be filled.

Connect to the web interface of the Kostal Piko inverter. If you do not know the IP address, call up the web interface using the serial number (http: // [SERIALNUMBER])
Enter your login information. Factory setting:
Username: pvserver
Password: pvwr
Enter the identifier P202L in the Portal Code field. Select Apply.
Enter the words go online in the Portal Code field. Select Apply.
A test transmission will start. If your inverter has already measured yield data, these will be transferred to the VCOM portal within the next five minutes.
Switch back to the inverter start page (Info) and close the Internet browser.
The setup of your inverter is now complete.
