The controller detects the parameters at the grid connection. The manipulated variables are calculated based on the grid operator's specifications and are transferred to the inverters. Using this closed-loop control circuit, the PV power station performs the grid-support functions for connecting medium or high voltage.

Your advantages

  • Reliable system operation and straightforward grid connection through compliance with all technical connection requirements
  • Intelligent automation solutions ensure low engineering and operating costs
  • Preprogrammed software enables fast startup of the power generation system (PGS)
  • Open interfaces enable customer-specific extension


Controller for feed-in control  

Controller for feed-in control

Certification in accordance with VDE-AR-N 4110/-20

As of this year, any power generation systems, whether combined heat and power plants, wind turbine generators or photovoltaic systems, that feed into the German medium- or high-voltage grid must be equipped with a certified control unit – the so-called PGS controller. While a manufacturer's declaration was sufficient in the past, a certificate issued by a DIN EN ISO/IEC 17065-accredited certification authority is now required. Our PGS controller is certified in accordance with VDE-AR-N 4110/-20 and therefore implements active power and reactive power requirements as well as monitoring voltage conditions at the grid connection point.
