POWER POINT TRACKING VIA SOLAR-BATTERY-CONVERTER
First Claim
1. A controller for controlling a converter configured to convert first power from a solar arrangement into second power for a battery arrangement, said controlling comprising, in response to detections of only values of a current signal flowing through the battery arrangement, perform maximum power point tracking via adjustments of an impedance of the converter for maximizing the current signal.

Abstract
Controllers (1) control converters (2) that convert first power from solar arrangements (3) into second power for battery arrangements (4). Said control comprises, in response to detections of values of current signals flowing through the battery arrangements (4), adjustments of impedances of the converters (2) for maximizing the current signals. A kind of maximum power point tracking is performed, without many multiplications of voltage signals and current signals provided by the solar arrangements (3) needing to be performed. Said adjustments may comprise adjustments in first directions in case the values of the current signals flowing through the battery arrangements (4) show increases and adjustments in different second directions in case the values of the current signals flowing through the battery arrangements (4) show decreases. Said adjustments may comprise adaptations of pulse width modulations of the converters (2).
