Abstract
A solar power inverter includes a number of photovoltaic (PV) inputs for connecting PV modules, a DC-DC converter at each of the PV inputs and a DC-AC inverter for converting the outputs of the DC-DC converters to an AC output power that may be fed into a power grid. The invention provides a method of controlling such a solar power inverter including the steps of identifying a PV input by assigning a priority value to the PV inputs and identifying the PV input with the highest assigned priority value, calculating a set value for the DC-DC converter at the identified PV input that is equal or below a maximum power capacity of the PV module connected to the identified PV input, and applying the set value for the DC-DC converter at the identified PV input.
