What device is placed between a solar panel and the power line to convert DC to AC?

• A. Inverter
• B. Battery
• C. Transformer
• D. Rectifier

Answer: (A)

Turning DC from the solar panel into usable AC for the grid or home is done by an inverter. Solar panels produce direct current, but most power lines and household devices run on alternating current with a specific voltage and frequency. The inverter converts the DC into AC and can also synchronize with the grid and manage power flow so the result is stable and safe for the line. A battery stores DC energy, not convert it. A transformer changes voltage on AC power, not DC. A rectifier converts AC to DC, the opposite of what you need here. So the device between the panel and the power line that provides AC is the inverter.
