  • Power controller, power generation system, and control method of power controller
    Patent number: 6800963
    Abstract: A power controller includes power storage means for storing DC power from DC power generation means that. Power conversion means include a DC/DC converter that converts a voltage when receiving a DC input. Charge and discharge means discharge electric power from the power storage means to the power conversion means and charge DC power from the DC power generation means in the power storage means. The charge and discharge means are provided among the DC power generation means, the power storage means and the power conversion means. Detection means detect electric energy of an external power load to which power from at least the power conversion means is supplied. Control means control operation of the charge and discharge means on the basis of the detected electric energy.
