Abstract

A generator connection arrangement for connecting the output of a wind generator to an inverter comprises an input for connection to the output of a wind generator 1, an output for connection to an inverter 6, and a back-up power supply 11 for selectively outputting a voltage for powering at least one control circuit of the inverter, dependent on the voltage at the input of the grid-tie. The back-up supply can continue to power the control circuit of the inverter in a prolonged period of little or no wind so that the inverter does not switch off. The back-up power supply may also supply the voltage to the input of the generator connection arrangement. The back-up power supply is thus able to power the control circuits of a wind generator having its output connected to the input of the grid tie, so that the control circuit of the wind generator do not switch off even in a prolonged period of little or no wind.
