Freese: Mobile Energy for lighting wind turbines

Wind turbines and thus the generation of CO2-reduced electricity are an essential part of the energy transition. The illumination of wind turbines represents a considerable safety aspect so that they are clearly visible to air traffic, for example. Lothar Freese uses a mobile control device to power the lighting – equipped with six 2kWh and one energy controller. Prior to refitting to powerful aentron lithium-ion battery modules, the electricity was generated by a diesel generator. In addition to the high level of noise, the considerable consumption of fossil resources should be emphasized in the context of producing green energy. 

The diesel had to be refilled up to twice a day in order to guarantee a permanent supply of the power generation required for the lighting. Thanks to the powerful aentron energy storage system, the generator is only needed to charge the batteries. When a defined charge level is reached, the modules are recharged via the generator and reach a full charge level after just two hours.
