Technical support
Services
Our technical support is a reliable and competent contact for your technical and specialist questions about our software products (1st and 2nd level support). In addition, product support and webinars are planned and carried out by technical support, questions are answered in our forum and learning videos are designed.
The technical support staff are qualified meteorologists and electrical engineers, and have worked for many years in climate and environmental research or in various projects in the field of renewable energies. They have accompanied the development of our software products for several years and are always a good contact point for specialist or technical questions, for the implementation of more complex projects or improvements in the software, for us and for our customers.
