power supply

A typical wind measurement site is far away from any grid connection and infrastructure. That’s why the measurement system needs an independent autonomous power supply. In most cases a small PV-power system consisting of a PV panel, a battery and a charge regulator is more than sufficient to provide enough power through the whole period of operation. Only in higher latitudes close to the polar circle or under strong icing conditions additional power might be needed. This can be provided by a small wind turbine installed on the met mast or by fuel cells or a diesel generator. 

If the measuring system is installed in an existing wind farm a grid connection kit is available. In this case a PV power system can provide back-up energy in case of a black out in the grid.
