What Is the Normal Ambient Temperature Range for an Inverter?
The ambient temperature range for an inverter generally depends on its design rating and cooling method. For most common industrial inverters, the typical ranges are:
-
Operating temperature: Most inverters operate reliably between -10°C and +40°C, with some models capable of handling up to +50°C. High-protection models (IP54/IP65) or those with dedicated cooling fans can sometimes operate short-term at temperatures up to +55°C, but long-term operation above +40°C may reduce lifespan.
-
Storage temperature: Typically between -20°C and +60°C, with some models supporting ranges as wide as -25°C to +70°C.
-
Important considerations:
- Exceeding rated temperatures can shorten the lifespan of power components and increase failure risks.
- Maintain ambient humidity between 20% and 90% (without condensation).
- Avoid direct sunlight, high-temperature heat sources, and poorly ventilated environments.
If you need, I can prepare a comparison table of temperature parameters for different inverter brands, making it easier to select the right model for your specific application.
