1-4 Grid-tied Wind Power Inverter Description
This product is a wind energy utility grid-tied system. Single-phase grid-tied wind power inverter is
different from traditional stand- alone type wind energy inverter; it does not need additional expensive
and large space required energy storage battery, hence free from considerable battery maintenance
expense. It efficiently converts power generated from wind turbine, high efficiently converts to AC
power and feed into grid, having the direct benefit of power generation and energy saving.
1-5 Wind Power System Operation
A. Normal Operation
The generator of wind power system should begin to generate electricity when the wind speed reaches
approximately 3 m/s. The rotor rotational speed will increase with higher wind speed. The generator
output is proportional to the third power of wind speed. Please refer to Figure 3 for the relationship
between power output and wind speed.

Note
The operational wind speeds and performance in the manual assume the condition of sea-level altitude,
steady winds, and moderate temperatures. High altitude, hot temperatures, turbulence and gusting
winds will usually bring the system performance lower than expectation.
