Choosing 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.
• Install the Sunny Boy in a location that maintains an ambient air temperature that is less
than 45°C. To maintain a safe internal component temperature, the Sunny Boy may re-
duce its power output if the ambient air temperature exceeds 45°C. (The cooler the air
temperature, the longer the life expectancy of any power electronics device.)
• The Sunny Boy is constructed in a rugged powder coated aluminium enclosure designed
for outdoor installations. However, care should always be taken to minimize exposure to
the elements. It is best to minimize 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.
• The inverter should be installed in a location that is inaccessible to children.
• The Sunny Boy may emit a slight vibrating noise when operating. This vibration is normal
and has no effect on performance, but it may be noticeable 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.
• If the inverter is installed outside, it should be mounted vertically or tilted back (see Figure
3-1).

Note: These inverter types are intended for operation in an
environment having a maximum ambient temperature of 45
°C.
