What is the purpose of an inverter connected to a solar panel output?
The correct answer is D: Convert the panel's output from DC to AC. What is the purpose of an inverter connected to a solar panel output is to convert the panel's output from DC to AC. Solar panels produce DC, inverters convert to AC. For amateur radio operators, this is important for solar power systems. Understanding this helps when using solar panels.
Exam Tip
Inverter connected to solar panel purpose = convert panel's output from DC to AC. Think 'I'nverter = 'I'nverts 'D'C to 'A'C. Solar panels produce DC, inverters convert to AC. Not AC ripple reduction, not voltage maintenance, not discharge prevention - just DC to AC conversion.
Memory Aid
"Inverter connected to solar panel purpose = convert panel's output from DC to AC. Think 'I'nverter = 'D'C to 'A'C. Solar panels produce DC, inverters convert to AC. Important for solar power systems."
Real-World Application
An inverter connected to a solar panel output: Its purpose is to convert the panel's output from DC to AC. Solar panels produce DC power, and the inverter converts it to AC for use with standard AC equipment. This is the purpose - DC to AC conversion.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. Reducing AC ripple on output isn't the purpose - inverter converts DC to AC. AC ripple reduction isn't the purpose.
Option B: Incorrect. Maintaining voltage with varying illumination isn't the purpose - inverter converts DC to AC. Voltage maintenance isn't the purpose.
Option C: Incorrect. Preventing discharge when panel not illuminated isn't the purpose - inverter converts DC to AC. Discharge prevention isn't the purpose.
