4.3.1 Exhaust Airflow
The heated exhaust air generated by the inverter must be ducted away from the device so that the
maximum permissible environmental temperature is not exceeded and / or the warm exhaust air does
not unnecessarily heat the installation room.
The exhaust airflow of the DC and AC cabinets occurs upward. This is achieved through the on-site
installation of an exhaust airflow (e.g. air conduit).
The exhaust airflow of the inverter cabinet occurs on the rear-side. The Sunny Central can be set up
with the rear panel directly against the opening in the building wall. An on-site sealing or a frame-like
air box with seals is to be installed for this purpose. The air box must be fastened onto the building
wall.
CAUTION!
Risk of crushing from metal parts.
• Remove the finger protection from the fan openings of the Sunny Central before
installing the exhaust airflow.
NOTICE!
Operational reduction of the Sunny Central through overtemperature!
For an appropriate cooling of the inverter, the following points have to be observed:
• Observe the indicated amount of air.
• Clean the ventilation openings (filter pads) and the exhaust grills at regular intervals.
• Expel the exhaust air separately out of the individual cabinet components in order to
avoid thermal short circuit breaks.
Information regarding the inverter
The specific configuration of the ventilation systems for each inverter is to be taken from the
Sunny Central Installation Requirements (separate document).
