Appendix 3 Capacitor Life Curve
* The ambient temperature herein means the temperature around the inverter body.
If the inverter is housed in a panel, the ambient temperature corresponds to the
temperature in the panel.
* Even when the ambient temperature is within the rating, the capacitor life is
shortened if ventilation is impeded due to bad installation conditions or dust.
