For most solar inverters, derating begins at around 45°C to 50°C (113°F to 122°F). When the temperature reaches this range, the inverter will gradually reduce its output to prevent overheating. . Solar inverters detect when they're getting too hot and throttle back, converting less solar DC into AC electricity, which is a shame when you need that energy to run the air conditioning. Excessive heat can have a great impact on the performance and durability of solar inverters. This is called 'temperature derating' and is smart design because it saves this expensive piece of kit from. . Since inverters are the heart of every photovoltaic setup, ensuring their long-term stability and performance is critical.
