Fan service
The inverter has three fans that run on a need basis depending on the temperature inside
the inverter. The fan speed is variable and controlled by the software. The lifetime of the
fans depends on the installation and the internal temperature of the inverter. A typical
replacement time for the fans is eight years.
The inverter indicates a warning when the fan run time counter is near the calculated life
time. After the run time counter warning, the inverter and fans continue their normal
operation, but the fans must be replaced with new ones to guarantee optimal operation of
the inverter.
The inverter indicates a warning if the fans are not running when they should be. In that
case the inverter continues operation but may limit the output power or may trip due to
overtemperature.
