A method and apparatus for converting DC power to AC power. For example, apparatus for converting DC power to AC power comprises an input adapted to be coupled to a high-powered distributed generator having a maximum voltage at a first voltage and an arc fault mitigation device, coupled to the input, for providing a second voltage at the input that is lower than the first voltage, where a difference between the first voltage and the second voltage is not large enough to cause an arc.

High-power microinverter and system

A method and apparatus for power imbalance correction comprising: a plurality of converters for converting a plurality of DC inputs to a multi-phase AC output, and coupling the multi-phase AC output to a multi-phase AC line, and a controller coupled to the plurality of converters. The controller determining whether phases of the multi-phase AC output are balanced, and controlling when all phases of the multi-phase AC output are not balanced, at least one converter of the plurality of converters to balance the multi-phase AC output.
