There are three options available: string inverters, microinverters, and power optimizers. . Photovoltaic (PV) systems, or solar power systems, convert sunlight into electrical energy via solar cells in panels. These cells generate direct current (DC), which requires conversion to alternating current (AC) for use in homes, businesses, or the grid—making inverters a critical component. Without the inverter, the DC power generated from the solar modules would not be utilized by grid-connected homes or premises that typically require AC. . Sarah Thompson is a solar energy expert specializing in Solar Solutions. String inverters have one centralized inverter — or, keeping with the metaphor — one central currency exchange station.
