Abstract:
1. An electrical power generation unit, comprising: a power source, said power source for generating electrical power; a metering device for measuring electrical power being generated by said power source, coupled to said power source; a generated power delivery switch connected to said power source, for controlling an amount of said electrical power generated by said power source delivered to an electrical utility grid; an energy storage system connected to said power source through a transfer switch, said energy storage system for storing electrical power as stored energy and delivering said stored energy as electrical power, and said transfer switch for controlling an amount of said electrical power generated by said power source delivered to said energy storage system; a metering device for measuring an amount of said stored energy in said energy storage system, coupled to said energy storage system; a stored energy delivery switch connected to said energy storage system, for controlling an amount of said electrical power delivered by said energy storage system delivered to said electrical utility grid; and a net metering control apparatus coupled to said metering device for measuring electrical power being generated by said power source, to said metering device for measuring said stored energy in said energy storage system, to said generated power delivery switch, to said stored energy delivery switch and to said transfer switch, said net metering control apparatus configured for being reading a value of said power source meter, reading a value of said stored power meter, and controlling said generated power delivery switch, said stored energy delivery switch and said transfer switch, so that that a total amount of electrical power from said power source and said energy storage system does not exceed a prescribed power limit.
