From firmware 6.1.2, we have adapted the IT security guidelines, among other things to meet the requirements of ISO / IEC 27001: 2022 certification. For this reason, the function ‘Deactivate passwords of a Solar-Log Base device via remote access from the portal’ is no longer available. However, our technical support can help you to deactivate the function.

This can now only be done by written authorisation with a verification of identity document from the plant owner. Please download the document and send it to us via the contact form. This gives Technical Support the authorization to establish a TeamViewer connection and can deactivate the passwords. In this way we comply with the current IT security criteria.
