This section provides guidelines to help you select the best mounting location, suggestions to insure
optimum performance, cautions and warnings that you should follow to avoid injury and/or
equipment damage, and step-by-step instructions for mounting a Sunny Boy inverter.
5.1 Selecting a mounting location
Consider the following guidelines, cautions, and warnings when choosing a mounting location for the
Sunny Boy:
• Do not install the Sunny Boy in direct sunlight. External heating from exposure to the sun may
cause excessive internal heating. This can result in reduced output power to protect the internal
components from damage. You must provide sufficient air circulation to dissipate the heat
generated by the inverter
• Install the Sunny Boy in a location that maintains an ambient air temperature that is less than
+113 °F (+45°C). To maintain a safe internal component temperature, the Sunny Boy may
power reduce if the ambient air temperature exceeds +113 °F (+45°C).
• Minimize the exposure to rain, snow and ice, etc. Do not install the Sunny Boy in a location
exposed to sources of direct water spray such as sprinklers or downspouts. Check for existing
electrical or plumbing installations in the walls before drilling mounting holes for the Sunny Boy.
• The inverter should be installed in a location that is inaccessible to children.
• The Sunny Boy emits a slight vibrating noise when
operating. This vibration is normal and has no effect
on performance, but it can be objectionable if the
inverter is mounted on a wall in a living area, on the
outside of a wall that is near a living area, or on
certain types of materials, such as thin wood
panelling or sheet metal.
WARNING
The Sunny Boy weighs 88 lb. (40 kg). To avoid injury, be sure to use proper lifting
techniques and secure the help of someone to assist in the unpacking and installation of
the inverter.
Occasionally, the rating label on the Sunny Boy will need to be referred to. For this reason,
it is required that the inverter be mounted so that the rating label on the side of the inverter
is visible.
