Appendix-2 Smoothing Capacitor Life
Ambient temperature (°C)
Note 1: Ambient temperature refers to the temperature measured at the location approximately 5 cm from the bottom
center of the Inverter.
Panel interior temperature is applied if the Inverter is stored in a control panel.
Note 2: The smoothing capacitor, which will deteriorate because of the chemical reaction caused by the temperatures
of the parts, should normally be replaced once every 10 years (which is the expected design life, and not
guaranteed).
However, if the ambient temperature is high, or the Inverter is used with its rated current exceeded, for
example, under overload conditions, its life will be significantly shortened.
