Claim 18:
19. A power station that includes a power module, a load terminal, and an electrical distribution network terminal, and having capability for energy storage and for conversion between direct current and alternating current, said power station controlling energy flow according to power generated by a photovoltaic source and the metering of a grid sensor, said power station receiving power from said photovoltaic source and selectively making electrical connections among said power module, said load terminal and said electrical distribution network according to the charge level of said storage battery, electric power available from said photovoltaic source and electrical power demands of said load, said power station comprising:
a power module that includes at least one maximum-power-point tracking converter, a battery charge controller that is connected to the maximum-power-point tracking converter, and a hybrid inverter with anti-islanding protection;
an emergency power by-pass contactor that connects said load to said inverter at times when electrical power is unavailable from said electrical distribution network;
a control unit that provides system control and central 60 Hz phase synchronization at times when power is unavailable from said electrical distribution network;
a grid sensor that includes an 1v1E power supply, said grid sensor monitoring two grid phases in real-time for metering voltage, current and energy flow, said grid sensor avoiding islanding and also initiating backup emergency power mode for the power station, said grid sensor also metering power for controlling the hybrid inverter for load demand; and
a battery that is connected to said power module, said battery storing energy at times when power from the photovoltaic source exceeds the load demand.
