Abstract:
1. A power converter system comprising: a DC-to-AC power converter configured to receive DC power from at least one DC power source; a grid switch coupled to the converter and configured to couple to a power grid; a plurality of selective couplings coupled to the converter, the selective couplings including load lines configured to be coupled to AC loads, the selective couplings being configured to selectively couple the converter to the load lines; and a controller coupled to the selective couplings and configured to be coupled to the power grid, the controller being configured to determine whether energy from the power grid satisfies at least one criterion and to control the grid switch to isolate the converter from the power grid, and to control the selective couplings to couple the converter to at least one of the load lines if the at least one criterion is unsatisfied, the controller being further configured to control the selective couplings to change a distribution of power provided by the converter to the load lines if power provided to the load lines is above an amount of power available to the converter to dynamically change which loads receive power from the converter while the at least one criterion is unsatisfied.
