Forced Ventila-
tion The inverter's temperature-controlled, variable-speed fan with ball-bearing support pro-
vides:
- optimal inverter cooling
- efficiency increases
- cooler components, thus improving service life
- least possible energy consumption and lowest possible noise level
- weight reduction due to a reduction of the cooling element surface

Grounding Kit
Option
Power derating Should there be insufficient heat dissipation in spite of the fan operating at maximum speed
(for example, inadequate heat transfer away from the heat sinks), the power will be derated
to protect the inverter when the ambient temperature reaches approx. 40 °C and above.
Derating the power reduces the output of the inverter for a short period sufficient to ensure
that the temperature will not exceed the permissible limit.
Your inverter will remain ready for operation as long as possible without any interruption.
Along with the solar module ground on the positive or negative
pole, solar modules can also be grounded with high resistance on
the positive or negative pole.
This requires the 100 kohm Grounding Kit option, which is insert-
ed into the corresponding fuse holder similar to a regular fuse for
the solar module ground.
