Claim:
1. A serially connected micro-inverter (SCMI) system comprising: a plurality of power sources for producing DC power; a plurality of micro-inverters, where each micro-inverter is coupled to at least one power source of the plurality of power sources, for converting the DC power into AC power; an AC bus for coupling the plurality of micro-inverters in series to form a string and for coupling the AC power to an AC line, wherein each of the micro-inverters comprises (i) an AC bus coupler for coupling the micro-inverter to the AC bus, wherein the AC bus coupler decouples the micro-inverter from the AC bus when a fault is detected with the micro-inverter, and (ii) a DC to AC inverter for converting DC input power from a coupled power source to AC output power; and a controller, coupled to the string, for:
