Abstract

A method for a power system having a string of a plurality of power sources connected across a power device includes connecting a plurality of safe voltage units having safety switches connected respectively across each of the power sources. The method includes sensing a plurality of parameters of the power sources, and monitoring for a signal transmitted from the power device. Each of the safety switches is activated to be OFF responsive to detecting the signal within a predetermined time period. Upon not detecting the signal from the power device within the predetermined time period, a safe mode of operation of the power system is entered in which the voltages of each of the power sources is reduced to a voltage level less than a predetermined voltage level by turning the safety switches ON.
