Understanding the Impact of Temperature on
Derating refers to the automatic reduction in inverter output when the internal temperature exceeds a certain limit. For instance, if the inverter gets too
Key Fac t: Most solar inverters operate optimally between 25°C to 40°C. Beyond this range, efficiency can drop by 0.5% to 1% for every 10°C increase in temperature. 2. Power Output Limitation (Temperature Derating) To protect internal components from excessive heat damage, inverters incorporate automatic temperature derating mechanisms.
In our datasheets inverters, and the inverter function of Multis and Quattros, are rated at 25oC (75oF). On average, derating at higher temperatures is as shown below (see paragraph 4 for the theoretical background). Low temp. High temp. 2. Battery chargers: continuous output rating as a function of temperature
To protect internal components from excessive heat damage, inverters incorporate automatic temperature derating mechanisms. As the temperature rises beyond safe operating limits, the inverter reduces its power output to prevent overheating. This can lead to: - Lower electricity generation during peak sunlight hours.
Typically, when an inverter reaches high temperatures, it gradually reduces its power output, by reducing the output current. This power reduction process is referred to as “derating”. Derating protects sensitive components and prolongs their lifetime. When the temperature drops, the inverter increases power output automatically.
