Appendix-2 Product Life Curve
Life of the Inverter smoothing capacitor
Ambient temperature refers to the surrounding temperature of the Inverter.The following diagram
shows the product life curve.
The smoothing capacitor, which will waste because of the chemical reaction caused by parts
temperatures, should normally be replaced once every 5 years.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.

Note: Ambient temperature refers to the surrounding (atmospheric) temperature of the Inverter, or
the temperature inside if the Inverter is encased or installed in an enclosure.
