1. A power station that selectively transfers electrical power Roma photovoltaic source ma electrical load, an electric power distribution network, and a storage battery in accordance with the power level generated by the photovoltaic source relative to the power level required by the electrical load, said power station comprising:
at least one maximum power point (MPP) tracker that is connected to said photovoltaic source;
an inverter that is electrically connected to said at least one maximum power point tracker and to said storage battery such that said inverter is responsive to electrical power from said at least one power point tracker and also responsive to electrical power from said storage battery, said inverter converting direct current to alternating current and also converting alternating current to direct current;
a controller that is in electrical communication with said storage battery, with said at least one maximum power point tracker, and with said inverter, said controller governing electrical current flow from said at least one maximum power point tracker to said storage battery and also governing electrical current flow from said storage battery to said inverter;
a transfer switch that is electrically connected to said inverter, said transfer switch having a first set of terminals that are electrically connected to said electrical load and a second set of terminals that are electrically connected to said electric power distribution network, said transfer switch having a first position wherein said inverter is electrically connected to said electrical load through said first set of terminals, said transfer switch also having a second position wherein said inverter is electrically connected to said electrical power distribution network through said second set of terminals; and
a control circuit that is responsive to the level of electrical power stored in said storage battery, said control circuit causing said transfer switch to locate in said first position wherein said transfer switch completes an electrical connection between said inverter and said first set of terminals of said transfer switch, or to locate in said second position wherein said transfer switch completes an electrical connection between said inverter and said second set of terminals of said transfer switch, and control circuit controlling the position of said transfer switch between said first and second positions in accordance with the level of electrical power stored in said storage battery, and in accordance with the level of electrical power generated from said at least one power point tracker relative to the power demand of said electrical load.
