摘要

A method and apparatus is disclosed relating to smart microgrids supported by dual-output off-grid power inverters with DC source flexibility that can (1) intelligently and selectively pull power from one or multiple DC sources including solar panels, wind generators, and batteries based on certain criteria; (2) invert DC power to AC power; (3) supply the AC power to two off-grid circuits individually to power various types of AC loads that require different AC voltages, power quality, and power levels; (4) supply DC power through one or multiple DC output ports to power DC loads; and (5) charge batteries. Two or multiple dual-output off-grid power inverters can daisy-chain to form a group to support a larger microgrid which is ideal for off-grid AC Level 1 and Level 2 EV charging.
