Libellula 55kW is a simple and robust turbine that can reach up to 57 kW. It is conceived in the same manner as large, high-power industrial installations and is equipped with an active yaw system with gear motor, professional wind direction and wind speed sensors, and load-bearing tubular tower with internal ladder. The peculiarity of Libellula 55kW is to have one main generator for energy production and one auxiliary generator for grid connection; while mechanical power limitation is obtained by means of a well proven passive blade pitch adjustment, electrical power regulation is carried out with an unconventional inverter/rotating-converter combination. This converter system allows the main generator to rotate at a variable speed, while the grid connected generator rotates at constant speed, as for the conventional stall regulated wind turbines with asyncronous generator directly connected to the grid.

Libellula 50kW is a small wind turbine designed to maximize efficiency in energy production, simplicity of installation, safety and reliability. Libellula 50kW can be installed on grid or off-grid. Its large rotor (19.4m) and its direct grid connection (no inverter) grant high performances even at low wind speeds. Libellula 50kW is the ideal wind turbine for farms, small industries and communities. With an average wind speed of 6 m/s, it will produce nearly 150.000 kWh/year.

Libellula DC is a special version of the Libellula wind turbines, designed in order to be used in stand-alone systems, not connected to the electrical network (off-grid). Mechanical and aerodynamic characteristics are those of the standard on-grid models while the electrical control system is designed to be connected with an external battery bank. The wind turbine is able to charge the battery bank, for the electrical supply of isolated users and for the electrification of remote areas without grid availability. Libellula DC allows the composition of a small and simple stand-alone power station supplied by renewable energy sources and equipped with accumulators for energy storage. Stored energy will be available in case of lack of wind.

Libellula 20 kW is a simple and efficient small wind turbine, designed to maximize efficiency in energy production. It is equipped with a large 2 bladed rotor which grant simplicity of installation and high performances even in less windy sites. Reliable and safe, Libellula 20kW is the ideal turbine for farms, small industries and communities.

The Libellula wind turbines are equipped with a remote control system, using a Short Message Service (SMS) designed to send and receive messages to/from a control terminal (mobile phone or other GSM connected equipment). The system allows a very simple use even with a mobile phone that can be used in order to receive messages and reports and/or in order to send requests of data or commands.
