5.1.4 Ventilation
Ambient Temperature / Air Quality / Humidity
To cool the inverter, the ventilation system must be free of any obstructions in order to
ensure the required inlet ventilation and heat dissipation.
The specified minimum clearances in
Appendix C
must be maintained for this purpose.
For safe operation, and maximum feed-in performance, the permissible ambient
temperature is between -20 and +50 °C. The rated values can be ensured at ambient
temperatures of up to +40 °C.
The air required for the SC 100 Outdoor is drawn through the ventilation system on the
roof of the inverter. Therefore, the corresponding device openings must be kept free
and clean according to the maintenance intervals specified in the user manual. The air
required for the SC 100 Indoor can either be drawn through the ventilation system on
the roof of the inverter or fed directly to the inverter through an air duct that is provided
by the customer.
The exhaust air (waste heat) is blown out through the front plinth panels. The exhaust
air of the SC 100 Indoor is blown out through an air duct in the roof of the inverter.
If the SC 100 Outdoor is exposed to direct sunlight, the internal temperature in the
inverter can increase and thus lead to a reduction in the output power. In this case, we
recommend using a sun shading system or installing the device in a shaded area or
under a module table. In case of existing buildings, the shaded area at the north side
of the building should be used.
