Communication Solutions
Reliable PV communications and controllability of PV power plants
The communication capability of photovoltaic plants is of great importance due to increasing energy industry requirements and the resulting increase in interconnections.Many plants, especially older ones, cannot keep up with the requirements of modern power plant IT. An often rudimentary IT structure with simple routers, minimal firewall protection and dial-up without secure VPN access can become a security risk for the plant.
As specialists in the field of Power Plant IT & Industrial Control Systems (PPIT & ICS), we advise, support and configure your entire power plant IT individually and ensure a secure and reliable connection of all communication participants and communication flows, including the required control systems in the network. In addition to maximum data security, we focus on flexible concepts and comprehensive data transparency for all stakeholders. In addition to a secure power plant IT, we also advise our customers on power plant control issues. Among other things, we implement solutions in the areas of remote monitoring and control, direct marketing and resulting obligations, such as Redispatch 2.0.

When should you look for modern power plant communication for your PV system?
