SOLAR PANEL COMPANION INVERTERS TO INTERFACE PHOTOVOLTAIC PANELS WITH RESIDENTIAL AND SMALL COMMERCIAL GRID
- 詳細技術說明
- Patent No.: 9,887,550Embodiments of the present application relate to methods, systems and computer program products for interfacing DC power with AC power grids. One embodiment relates to minimally-intrusive methods and systems for converting DC voltage outputs of a plurality of solar panels to a quasi-square wave AC voltage that can be directly interfaced with an AC power grid or a load that is configured to receive an AC load.
- *Abstract
-
Methods and systems relating to a control system for an electrical energy outputting device are provided. The method may include receiving voltages from a plurality of power devices connected to a controller; identifying, by the controller in real time, relative levels of voltages output from each power devices; generating, by the system in real time, a waveform for each respective voltage of the power devices so that, for each cycle, power extracted from each generated waveform over a single waveform cycle is based the relative levels of voltages from each respective power device and so that the power level, for each cycle, from each waveform is higher than the power level of the other generated waveforms that have lower voltages; and summing, in real time, the generated waveforms to form an AC waveform.
