Solar Inverters: Efficient DC to AC Conversion for Optimal Energy Use

An on-grid inverter connects solar electricity generating systems to the utility grid. It converts the direct current (DC) produced by solar panels to alternating current (AC) needed by the utility grid. Some power produced by the solar panels is returned to the grid, and consumers are able to take electricity from the grid when needed and when solar energy production is insufficient. On-grid inverters often have anti-islanding protection for the safety in case of grid failures. They have a major function in net metering systems, allowing consumers to credit surplus power given to the system and effectively lowering electric bills.
