Capacitor Life Curves

The DC bus inside the inverter uses a large capacitor as shown in the diagram below.
The capacitor handles high voltage and current as it smoothes the power for use by the
inverter. So, any degradation of the capacitor will affect the performance of the inverter.

Capacitor life is reduced in higher ambient temperatures, as the graph below
demonstrates. Be sure to keep the ambient temperature at acceptable levels, and
perform maintenance inspections on the fan, heat sink, and other components. If the
inverter is installed on a cabinet, the ambient temperature is the temperature inside
the cabinet.
