Question

In renewable energy systems, the primary function of an inverter is to:

• A. Store electrical energy
• B. Convert DC to AC
• C. Increase voltage levels
• D. Regulate current flow

Hint:

Inverters are key components in solar power systems, enabling compatibility with AC appliances.

Answer 1

The Correct Option is B

Inverters are electronic devices that convert direct current (DC) from sources like solar panels or batteries into alternating current (AC), which is the standard form of electricity for household and industrial use.

Answer 2

Name-to-Function: 'Inverter' literally means it inverts (flips) the type of current — a strong hint to the function itself.

Solar panels and batteries produce DC, but homes/grids run on AC, so the inverter's core job is converting DC to AC — matching option 2.

Storing energy is a battery's job, increasing voltage is a transformer's job, and regulating current flow is a separate control function — none of these is what 'invert' means.
