Abstract:
A method and apparatus is disclosed that can intelligently invert DC power from single or multiple DC sources to single-phase, split-phase, or three-phase AC power, supply the AC power to the electric power grid when the grid is on, or supply AC power to electric devices or loads when the grid is down. A Smart and Grid-Flexible Power Inverter, or On/Off-Grid Power Inverter, is disclosed that can work in either the on-grid or off-grid mode, and switch back and forth between the two modes manually or automatically depending on the power grid conditions. The system provides a simple and cost-effective solution for areas where the power grid has frequent outages or long downtimes.

Claim (Index 1):
A scalable DC to AC power inversion system for providing AC power to the electric grid or to an off-grid AC circuit respectively from a plurality of individual DC power sources each having a DC output port, comprising:\n a) at lease one on-grid power inverter, each having at least one DC input port, an on-grid AC input port, and an on-grid AC output port; b) at least one on/off-grid power inverter, each having at least one DC input port, an on-grid AC output port, and an off-grid AC output port; c) the on-grid AC output port of each inverter being connected in a daisy chain to the on-grid AC input port of the next inverter, except for the on-grid AC output port of the first inverter being connected to the grid; d) said on-grid AC output port of the first inverter being arranged to supply AC power produced by all inverters to the grid when the grid is on; e) the off-grid AC output port of each on/off-grid power inverter being connected to an off-grid AC circuit and arranged to supply AC power to AC loads in the off-grid circuit when grid is down; and f) whereby said system is incrementally scalable by adding or subtracting DC power sources and daisy-chained inverters.
