  • Battery charger apparatus and method for a photovoltaic system
    Patent number: 8629647
    Abstract: A battery charger, or charge controller, for a photovoltaic system is disclosed, comprising a maximum power point tracker (MPPT) circuit, which may be bypassed by means of a bypass circuit. The bypass circuit may be a simple electrical wire or link. The battery charger is operable to track the maximum power of a photogenerator by means of the MPPT, or to bypass the MPPT and disable it, in dependence on whether the power loss which results from the MPPT would be greater than the power saving achieved by tracking the maximum power point of the photogenerator. Also disclosed is a control unit for use in such a battery charger, and a method for controlling such a battery charger.
