Inverters equipped with over- and under-voltage protection automatically monitor the input and output voltage levels. If the voltage deviates from the preset safe range, the inverter will either shut down or adjust its output to bring the voltage back within acceptable limits. One of the most common methods is through the use of voltage sensors. These sensors are like the eyes of the inverter, constantly monitoring the voltage levels at different points in the. . This article will introduce you to some common functions of solar inverter protection, including input overvoltage/overcurrent, input reverse polarity, output overcurrent/short circuit, anti-islanding, surge protection, etc.
