Hi, With 25hp or 18.65kW motor, it should be possible to generate at least 15kW of power in generator mode. 11kW seem very cautious. Ghanashyam

The KW that can be generated by this motor would be the motor rating divided by 1.73, so if you have a motor that is 25 HP= 18.65 KW, as a single phase Grid tied generator, the available power would be 11 KW.
