Soma Power offers the Soma 1000 wind generator. This wind generator can be efficiently used for battery charging applications as well as for grid connected applications. This tilt up type wind generator incorporates two blades and each blade measures 2.7 m in diameter.
The hollow molded blades are made of fiber glass reinforced plastic. The Soma 1000 wind generator offered by Soma Power incorporates a permanent magnet 3 phase AC alternator and delivers an output in the range of 24, 32, 36, 48, 110 or 120 V. This wind generator operates in 300 to 800 rpm speed ranges. The is wind turbine out puts a maximum voltage of 1000 W at 10 m/s wind speed and its estimated peak out put is 1200 W.

The cut in wind speed of this generator is 3.5 m/s and this wind generator can withstand a maximum wind speed of 50 m/s. For the purpose of battery charging applications a controller is utilized to convert the incoming 3 phase AC power from the wind generator. The excess power is diverted to an inbuilt dump load by utilizing a PWM circuitry thus regulating the speed of the wind generator. To do away with the requirement of long-sized connecting cables from the wind generator a transformer is incorporated at the batteries.
For grid-connected applications a controller is utilized to correct the AC output from the wind turbine. An AC failure relay included in the wind turbine prevents the AC supply to the grid during grid failures and the included independent crow bar thyristor circuit secures the DC output during regulator failure.
