A grid-tied solar inverter converts DC power from your panels into AC that matches the grid's voltage, frequency, and waveform. It continuously monitors grid conditions, feeds excess energy back for net metering credits, and automatically shuts down during outages to. The primary role of a solar inverter is to convert DC solar power to AC power. The solar inverter is one of the most important parts of a solar system and is often overlooked by those looking to buy solar energy. Learn how synchronization works and why it can earn you credits.

Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine. But for solar energy to seamlessly power our homes, offices, and communities, there's a critical component that bridges the gap between solar panels and the electrical grid: the solar grid-connected inverter.
