Which risk increases when impedance matching fails in solar inverters?

A)Thermal runaway in the MOSFETs
B)Increased grid harmonic distortion
C)Photovoltaic cell front glass delamination
D)Backsheet material electrical breakdown

💡 Explanation

Thermal runaway increases because mismatched impedance prevents optimal power transfer, creating excess heat due to increased currents. This mechanism, Joule heating, overwhelms the cooling system; therefore, overheating occurs rather than grid issues or panel delamination under standard conditions.
