All power curves on this site under done under "Progressive Load." This means that as the RPM's or wind speed increases, the PMA or generator is placed under a progressively more intensive amp load so it is working harder and harder. Progressively optimized means the "BEST CASE SCENARIO." Wind turbines connected to only one voltage battery source is not progressively optimized.
