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.

Service code/PARAKO

The system-specific shutdown limits can be adapted to the grid operator's requirements using the PARAKO parameterisation software or the service code for the PLENTICORE plus and PIKO IQ inverters.

Before a personal password can be allocated, we, KOSTAL Solar Electric, need you to confirm that you're an electrician from an authorised specialist company and that you won't disclose the password to the plant owner. Therefore, please download the registration form, fill it out, scan it in and return it via our contact form.

Complaints

You can submit a complaint outside our hotline opening hours. Please complete the questionnaire  and send it to us, together with the log data, as an attachment to our contact form. If the inverter isn't included in our free KOSTAL Solar Portal, please interrogate the log data from the device.

Great news: Your request will be treated as a priority.
