2.2 Placement of the Sunny Boy
The Sunny Boy is a sophisticated electronic device and is therefore sensitive to humidity
within
the case.
NOTE:
If the Sunny Boy is placed outside, the humidity during the installa-
tion should be as low as possible - pay special attention that it does not
rain. If moisture is enclosed in the case it will eventually condense within
the device which could damage the electronics.
A suitable position must be found for the inverter while the PV-plant is designed. In the
following you will find a summary of the most important criteria.
Criteria for device mounting:
•
Due to the high protection class (NEMA 4X) of the enclosure the installation is pos-
sible indoors as well as outdoors.
•
If possible, do not expose the inverter to rain despite NEMA 4X.
•
Keep the DC cabling from the solar panel to the inverter as short as possible.
•
Avoid installation in the living area because a slight noise emission is possible.
•
Avoid mounting on resonant parts (e.g. thin wooden panels, plaster panels, etc.).
The Sunny Boy tends to slightly vibrate when under load.
•
Provide accessibility for installation and later service.
•
Installation in eye-height allows to easily read the operating LEDs or the Sunny Dis-
play.
