Abstract: According to a first aspect of the disclosure, there is provided a method of controlling a power output of an inverter. The method comprises measuring an output current of the inverter, determining a difference between the output current and a reference current, and controlling a reference input voltage of the inverter as a function of the determined difference. In a second aspect of the disclosure, there is described a system for controlling a power output of an inverter. The system comprises an inverter arranged to output a current as a function of a reference input voltage. The system further comprises a controller arranged to determine a difference between the output current and a reference current. The controller is further arranged to control the reference input voltage as a function of the determined difference. The method may allow for control of a photovoltaic inverter at a power less than its maximum capability for a given solar irradiation, which may avoid the problem of the photovoltaic array voltage rising above a level where the inverter can run.
