High temperatures can reduce solar inverter efficiency, limit power output, and shorten lifespan. Photovoltaic modules are tested under standard conditions of 25 °C, with temperature coefficients for different technologies ranging from -0. When the temperature rises from 25 °C to 70 °C, output power can drop by 10%–20%, while 20–30 °C is closer to the ideal operating range. Solar inverters are the backbone of PV systems, converting direct current (DC) from solar panels into usable alternating current (AC) for homes, businesses, and industrial applications. However, like all electronic devices, they are sensitive to extreme environmental conditions. In this process, power devices (such as IGBTs and MOSFETs), inductors, capacitors, and transformers all produce heat.
