Service Code
The service code (formerly PARAKO code) for PLENTICORE and PIKO IQ inverters can be used to adjust the system-specific switch-off limits according to the grid operator's requirements. As the system operator is not permitted to change the settings on the inverter, access to the settings on the web server (for PLENTICORE and PIKO IQ) or the parameterisation software (for PIKO 4.2 - 36) is protected by a personal password. As an installer, you can find this service code in your user account (under "My profile") of the KOSTAL Solar Terminal.

- If you are already registered as a user in the KOSTAL Solar Terminal, you can view your service code in your profile at any time. Please note that you need the "Installation" role for this. If you are not yet registered as an installer, please ask your company's admin to assign you the appropriate role.
- Your company is already registered as a customer in the KOSTAL Solar Terminal and you would like to register as an employee? Then please contact the administrator in your company. They will invite and add you as an employee. Please note that you will be assigned the "Installation" role. In this way you will receive your personal service code.
- If you and your company are not yet registered in the KOSTAL Solar Terminal, please register your company for the KOSTAL Solar Terminal for the first time. With this registration, you become the administrator for the KOSTAL Solar Terminal within your company and can add other people within your company to the KOSTAL Solar Terminal with an invitation. To view the service code in your profile, the role "Installation" must be assigned.
