Renewable Energy: Hybrid Inverter

The Sun is one of the most promising sources of renewable energy. Solar energy can be converted into both electricity and heat. Actual applications of renewable energy (specifically solar panels) make broad use of converting the VDC of series- and parallel-connected photovoltaic cells into VAC using an inverter that powers the load. Russian and international manufacturers offer quite a broad range of inverters for solar panels. This paper critically analyzes the existing inverter circuits and outlines the technical contradictions arising from using them. It proposes an alternative hybrid inverter circuit to address these issues. The microprocessor controls proposed herein enable flexible inverter configuration. The proposed battery charge controller can extend the battery service life.
