Abstract
57) ABSTRACT A method of operating a pump system, the pump system comprising a pump arranged to be rotated with an AC motor, an inverter, the output of which is electrically connected to the AC motor and a photovoltaic panel system electrically connected to feed DC power to an inverter. The method comprises setting a voltage limit (Vboost), determining continuously voltage obtained from the photovoltaic panel system, when the determined voltage of the photovoltaic panel system is below the set voltage limit, controlling the output frequency of the inverter such that the ratio between output voltage of the inverter and the output frequency is substantially constant, and when the determined voltage of the photovoltaic panel system exceeds the voltage limit (Vboost), controlling the output frequency of the inverter for keeping the voltage of the photovoltaic panel system substantially at the voltage limit.
