A preferred embodiment of the electrical power system of the present invention includes a power conditioning unit which is configured to receive the DC electrical output signal to deliver an AC output signal to a grid-connected load. Preferably, the power conditioning unit includes a controller which is configured to monitor the AC output signal so that the power conditioning unit may cease delivering the AC output signal when a characteristic of the AC output signal satisfies an established criterion.

1. A method for reducing size of a non-detection zone in a grid-connected power system having an electrical power generator with an interface to the grid, the method comprising the steps of:measuring frequency deviation between an output signal of the grid and an output signal of the grid-connected power system; applying the measured frequency deviation to the output signal of the grid-connected power system; and when the measured frequency of the output signal of the grid-connected power system satisfies an established cut-off level, discontinuing the output signal of the grid-connected power system.
