Abstract
Low voltage ride through systems, methods, and apparatus are disclosed. An exemplary method includes applying real power from a photovoltaic array to an AC grid with an inverter, detecting a sag in the voltage in the AC grid, and responsive to the sag in the voltage in the AC grid, power from the photovoltaic array is utilized to provide power to at least one inverter-related component. When the sag in the voltage has abated, real power from the photovoltaic array is applied once again to the AC grid.
