The leading grid-tied inverter is now available for wind applications

The Windy Boy incorporates the same proven technology used in all Sunny Boy inverters with special firmware that permits direct grid-tie operation with compatible wind turbines - without batteries. The Windy Boy is available in models  ranging from 1800W to 7000W for increased system sizing versatility. Contact us for information on compatible wind turbine models and system design considerations.

The Windy Boy is able to be connected to any wind turbine with a three phase, rectified DC output within the operating ranges of the inverter. Multiple Windy Boy inverters can be paralleled for larger turbines. Each turbine manufacturer pre-configures the inverter for optimum operation with their specific wind turbine. Historically, grid-tied wind systems have been connected to the grid through charge controllers, batteries and inverter/chargers. The resulting total efficiency of the power conversion from the wind turbine to the grid can be as low as 50%. With the Windy Boy, the peak efficiency is the same as the Sunny Boy PV models. For example, when using a 2500W Windy Boy the efficiency can be as high as 94.5%. The overall system cost is also greatly reduced because components such as the charge controller, batteries and associated switch gear can be eliminated from the system. Increased total energy capture combined with a reduction of balance of system components greatly reduces the installation and operating costs of a grid-tied wind system. Without inverter settings, battery setpoints or batteries to maintain or replace, Windy Boy systems are greatly simplified and virtually maintenance free.
