This invention concerns an electrical energy supply and distribution system. The system is able to handle both large centralized electricity generation plants, as well secondary energy sources which are becoming increasingly important. These sources may or may not be connected to deliver electrical energy to a 50 Hz AC power distribution grid. The system comprises a supply side where multiple electrical energy generators are connected via connections ports, involving conditioning circuitry, into a single DC electrical energy source. This energy source may be supplied to a common inverter system to convert it to AC for transmission on over a power grid. A rectifier may take the AC power from the grid and delivers it to loads. Whether an AC grid in involved or not, on the delivery side energy is delivered to multiple loads via connection ports involving conditioning circuitry. Any of the generators or loads may be taken offline or connected back into the system at will.
