The flexible add-on module for controlling active and reactive power in PV power plants. The PCU allows you to comply with VDE-AR-N 4105, BDEW Medium Voltage Directive and EEG (German Renewable Energy Law) recommendations and specifications without additional software.

The PCU add-on module enables the discrete and dynamic specifications on active and reactive power control to be processed and calculated. The PCU receives the information from the energy supplier and forwards it to the WEB'log. The PCU is integrated into the complete measurement recording system and automatically controls the grid feed-in of the solar power according to requirements.
