NOVELTY - The solar inverter device has a connecting branch from each PV module (PV1-PV3) output to a common bus. Each branch includes a branch control circuitry to selectively couple the corresponding PV module output to the common bus. During a first half of a grid cycle, one or more of the capacitors (C1-C3) is discharging to the power grid while a balance of the capacitors are charging in preparation for their discharge during a second half of the grid cycle.    USE - Solar inverter device for operatively coupling to electrical power grid, used in solar applications for power conversion, e.g. direct current to alternating current (DC-to-AC) conversion, such as a DC-to-AC inverter device used in a system for converting discrete a DC source from batteries or photovoltaic cells or other suitable DC source into a relatively smooth AC voltage output that may be used by AC devices and/or provided to an electric power grid.    ADVANTAGE - The DC-to-AC inverter device is relatively less expensive, includes significantly fewer components, and/or reduces or otherwise eliminates harmonics, relative to conventional DC-to-AC inverter designs. Allows for efficient DC-to-AC conversion. Ensures adequate voltage for the target application, or allows for optimizing the output of a photovoltaic array to ensure maximum power point tracking. Enables supply of power to an electrical power grid with high efficiency, high power factor, and low harmonic distortion at relatively lower cost, as compared to conventional designs. Eliminates a number of components of conventional inverter designs, using fewer and less expensive components that may be incorporated into solar systems or modules. A global power supply can be used, and each control circuit need not have its own individual power supply. Ensures that there is sufficient voltage across the solar modules to operate near their maximum power point, and for the solar module stack to have sufficient voltage to be able to discharge to the grid.
