  • Reasons for derating of photovoltaic inverters

    Reasons for derating of photovoltaic inverters

    Inverter thermal derating is the intentional and automatic reduction of power output by the inverter to prevent its internal components from exceeding safe operating temperatures. Think of it as a built-in safety feature. The inverter is the operational core of any solar or energy storage system, diligently converting DC power from panels or batteries into usable AC electricity. However, the performance and longevity of solar inverters can be significantly affected by high operating. Under conditions where the inverter risks operating with internal temperatures above the nominal level or with an overpower on the direct current (DC) side exceeding the nominal power of the alternating current (AC) output of the inverter, a limitation of the generation curve is observed, i. In extreme situations, this phenomenon can even stop production. The main causes of derating.
