What is the primary function of a microinverter?

• A. They supervise grid operations
• B. They convert DC to AC
• C. They monitor temperature
• D. They store energy

Answer: (B)

The main idea here is converting the electricity to a usable form. A microinverter takes the direct current produced by a solar module and converts it into alternating current that can feed the household panel or the grid. Doing this conversion at the module level means each panel operates with its own maximum power point tracking, helping optimize energy harvest even if other modules are shaded or mismatch. It’s not about supervising grid operations, which is handled by other systems and controls, nor is it primarily about temperature monitoring. And storing energy isn’t a function of a microinverter—the energy storage role belongs to batteries or storage systems.
