AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 15-24 is confirmed.
Claims 1-14 were not reexamined.
15. A scalable DC to AC power inversion system for providing AC power to a power grid from a plurality of individual DC power sources each having a DC power output port, comprising:
a) a plurality of power inverters, each of said power inverters including a single DC-AC inverter, at least two DC power input ports coupled to the single DC-AC inverter, an AC power input port, and an AC power output port coupled to the single DC-AC inverter, each of said DC power input ports having one DC power source connected thereto;
b) said AC power output port of each power inverter being connected in a daisy chain to the AC power input port of the next power inverter, except for the AC power input port of the first power inverter being left open, and the AC power output port of the last power inverter being connected to a power service panel of the power grid;
c) whereby said system is incrementally scalable by adding or subtracting DC power sources and daisy-chained inverters.
