A high efficiency solar power system combining photovoltaic sources of power () can be converted by a base phase DC-DC photovoltaic converter () and an altered phase DC-DC photovoltaic converter () that have outputs combined through low energy storage combiner circuitry (). The converters can be synchronously controlled through a synchronous phase control () that synchronously operates switches to provide a conversion combined photovoltaic DC output (). Converters can be provided for individual source conversion or phased operational modes, the latter presenting a combined low photovoltaic energy storage DC-DC photovoltaic converter () at string or individual panel levels.

Converter controlled solar power supply system for battery based loads

The inventive technology, in certain embodiments, may be generally described as a solar power generation system with a converter, which may potentially include two or more sub-converters, established intermediately of one or more strings of solar panels. Particular embodiments may involve sweet spot operation in order to achieve improvements in efficiency, and bucking of open circuit voltages by the converter in order that more panels may be placed on an individual string or substring, reducing the number of strings required for a given design, and achieving overall system and array manufacture savings.

Solar panel power conversion circuit

Renewable electrical energy is provided with aspects and circuitry that can harvest maximum power from an alternative electrical energy source () such as a string of solar panels () for a power grid (). Aspects include: i) controlling electrical power creation from photovoltaic DC-AC inverter (), ii) operating photovoltaic DC-AC inverter () at maximal efficiency even when MPP would not be, iii) protecting DC-AC inverter () so input can vary over a range of insolation and temperature, and iv) providing dynamically reactive capability to react and assure operation, to permit differing components, to achieve code compliant dynamically reactive photovoltaic power control circuitry (). With previously explained converters, inverter control circuitry () or photovoltaic power converter functionality control circuitry () configured as inverter sweet spot converter control circuitry () can achieve extraordinary efficiencies with substantially power isomorphic photovoltaic capability at 99.2% efficiency or even only wire transmission losses.
