A solar inverter's performance is closely tied to its operating temperature. . This Technical Note summarizes the derating properties of SolarEdge Inverters and Power Optimizers. This document explains how inverter temperature is controlled, what causes temperature derating and what can be done to prevent it. While most manufacturers provide a standard. . 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. Derating protects sensitive components within the unit and prolongs its lifetime.
