2 Safety
2.1 Appropriate Usage
The Sunny Boy is a PV inverter that converts the DC current of solar cells to AC current and feeds it
into the public grid.
Principle of a PV system with this Sunny Boy
The Sunny Boy may only be operated with PV generators (modules and cabling) of protection class
II. Do not connect any sources of energy other than PV modules to the Sunny Boy.
PV modules with large capacities relative to ground, such as thin-film modules with cells on a metallic
substrate, are only to be implemented if their coupling capacity is below 50 nF/kWp.
During grid feeding, a leakage current whose magnitude depends on the manner in which the
modules are installed and on the weather (rain, snow) flows from the cells to ground. This operational
leakage current is not to exceed a value of 50 mA.
When designing the PV system, ensure that the values comply with the permitted operating range of
all components at all times. The free design program "Sunny Design"
(www.SMA.de/en/SunnyDesign) will assist you. The manufacturer of the PV modules must have
approved the modules for use with this Sunny Boy unit. You must also ensure that all measures
recommended by the module manufacturer for long-term maintenance of the module properties are
taken (see also Technical Information "Module Technology", in the download area of
www.SMA.de/en).
Do not use the Sunny Boy for purposes other than those described here. Alternative uses,
modifications to the Sunny Boy or the installation of components not expressly recommended or sold
by the manufacturer void the warranty claims and operation permission.

2.2 Safety Instructions
DANGER!
Danger to life due to high voltages.
• All work on the Sunny Boy must only be carried out by a qualified personnel.
CAUTION!
Danger of burn injuries due to hot housing parts!
• Do not touch the housing of the Sunny Boy during operation.
NOTICE!
Foreign objects or water entering the Sunny Boy can damage the device!
Once the Electronic Solar Switch has been pulled out, the Sunny Boy only provides
protection degree IP21. The Sunny Boy is then no longer protected against water and
contamination with dirt!
In order that the protection level IP65 is also provided during a temporary
decommissioning, proceed as follows:
• Unplug all DC plug connectors and seal them with the protecting caps provided.
• Attach the Electronic Solar Switch again.
Grounding the PV generator
Comply with the local requirements for grounding the modules and the PV generator. SMA
reccomends to electrically bond the module frames, the racks and all metal surfaces and
ground these in order to have optimal protection of the system and personnel.

3 Overview
3.1 Identifying the Sunny Boy
You can identify the Sunny Boy using the type label. The type label can be found on the right side of
the housing and contains information about the serial number, the device type as well as technical
data.

4.1 Selecting the Mounting Location
Weight
Ambient Conditions
• The mounting location and mounting method must be suitable for the weight and dimensions.
• Mount on a solid surface.
• The installation location must be accessible at all times (do not mount in inaccessible places).
• The Sunny Boy must be easy to remove from the mounting location at any time.
• The Sunny Boy must not be in operation in ambient temperatures outside the range of -25 °C
and +60 °C. For optimal operation, the ambient temperature should not exceed +40 °C.
• Do not expose the Sunny Boy to direct sunlight, so as to avoid power reduction due to excessive
heating.
DANGER!
Danger to life due to fire or explosion!
Despite careful construction, a fire can occur with electrical devices.
• Do not mount the Sunny Boy on flammable construction materials.
• Do not mount the Sunny Boy near highly flammable materials.
• Do not install the Sunny Boy in potentially explosive areas!
CAUTION!
Danger of burn injuries due to hot housing parts!
The temperature of individual parts of the housing, in particular the temperature of the
heatsink and the components inside the Sunny Boy can reach more than 60 °C. Touching
could result in burns!
CAUTION!
Risk of injury due to the heavy weight of the Sunny Boy!
The Sunny Boy weighs more than 28 kg.
• Consider the weight of the Sunny Boy when choosing the location and method of
installation.
SMA Solar Technology AG Mounting

• In a living area, do not mount the unit on
plasterboard walls (or similar) in order to avoid
audible vibrations.
The Sunny Boy can make noises when in use which
can be regarded as a nuisance when installed in a
living area.
• Vertical installation or tilted backwards by max. 45°.
• Install at eye level to allow operating modes to be read at all times.
• Never install the device with a forward tilt.
• Do not install horizontally.
Safety Clearances
Observe the following safety clearances to walls, other devices or other objects in order to guarantee
sufficient heat dissipation and enough space for removing the Electronic Solar Switch:
Direction Minimum Clearance
Sides 20 cm
Top 20 cm
Bottom 50 cm
Front 5 cm

4.2 Mounting the Sunny Boy
To make the job easier, we recommend you use the
supplied wall bracket to mount the Sunny Boy. For
vertical installation on solid concrete or block walls, for
example, you can fit the bracket using 8 mm x 50 mm
hexagon bolts to DIN 571 standard, stainless steel type,
and with wall plugs type SX10.
When selecting the mounting materials, be sure to take
into account the weight of the Sunny Boy (28 kg).
If you do not want to use the supplied wall bracket as a template, observe the dimensions shown in
the illustration below. The procedure for mounting the inverter using the wall bracket is described on
the following pages.

1. Mount the wall bracket (1). In order to mark the
positions for the drill holes, you can use the wall
bracket as a drilling template.
2. Now hang the Sunny Boy onto the wall bracket (2)
using its upper mounting plate so that it cannot be
moved sideways.
3. Fix the Sunny Boy onto its bracket by screwing the
supplied M6x10 bolt into the central threaded hole
at the bottom of the bracket (3).
4. Make sure that the Sunny Boy is positioned
securely on the bracket.
