Micro-inverter vs string inverter in Power Electronics - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the sentence: A micro-inverter is installed on each {{BLANK_1}} panel.

Power Electronics

A micro-inverter is installed on each [1] panel.

Bpower

Csolar

Dbattery

💡 Hint

Common Mistakes

Choosing 'battery' because it stores power, not generates it.

A micro-inverter is attached to each solar panel to convert DC to AC individually.

2fill in blank

medium

Complete the sentence: A string inverter connects multiple panels in a {{BLANK_1}}.

Power Electronics

A string inverter connects multiple panels in a [1].

Aseries

Bparallel

Ccircuit breaker

Dbattery bank

💡 Hint

Common Mistakes

Choosing 'parallel' because it increases current, not voltage.

String inverters connect solar panels in series to combine their output before conversion.

3fill in blank

hard

Fix the error: In a string inverter system, if one panel is shaded, the {{BLANK_1}} output is affected.

Power Electronics

In a string inverter system, if one panel is shaded, the [1] output is affected.

Bsingle

Cbattery

Dentire

💡 Hint

Common Mistakes

Choosing 'single' because only one panel is shaded, but the whole string is affected.

Because panels are connected in series, shading one panel reduces the entire string's output.

4fill in blank

hard

Fill both blanks to complete: Micro-inverters convert DC to AC {{BLANK_1}} each panel, while string inverters convert DC to AC {{BLANK_2}} the panels.

Power Electronics

Micro-inverters convert DC to AC [1] each panel, while string inverters convert DC to AC [2] the panels.

Aindividually

Bcollectively

Cquickly

Dslowly

Attempts:

💡 Hint

Common Mistakes

Mixing up 'individually' and 'collectively'.

Micro-inverters work on each panel separately; string inverters work on the combined output of all panels.

5fill in blank

hard

Fill all three blanks to complete: Micro-inverters improve {{BLANK_1}} by optimizing each panel, reduce {{BLANK_2}} risk, and increase {{BLANK_3}} flexibility.

Power Electronics

Micro-inverters improve [1] by optimizing each panel, reduce [2] risk, and increase [3] flexibility.

Csystem

Dcost

💡 Hint

Common Mistakes

Choosing 'cost' instead of 'system' for flexibility.

Micro-inverters improve efficiency, reduce fire risk, and increase system flexibility compared to string inverters.
