2.1 Appropriate Usage
The Sunny Boy is a PV inverter, which converts the DC current of the PV generator to AC current and
feeds it into the public grid.
Principle of a PV plant with this Sunny Boy
Th e Su nny Boy may onl y be o per ate d wi th P V ge ner ato rs ( modu les and cabling) of protection classII.
Do not connect any sources of energy other than PV modules to the Sunny Boy.
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 device. 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 SMA Solar Technology AG void the warranty claims and operation permission.

SMA Solar Technology AG can preset special grid parameters for other countries/installation
locations according to customer request, after evaluation by SMA Solar Technology AG. You can
make later modifications yourself by changing software parameters with respective communication
products (e.g. Sunny Data Control or Sunny Explorer) (see section 5.6”Setting the Grid and Country
Parameters” (page36)). To change grid-relevant parameters, you need a personal access code - the
so-called SMA Grid Guard Code. The application form for the personal access code is located in the
download area at www.SMA.de/en, in the "Certificate" category for each inverter.

2.2 Safety Precautions
DANGER!
Danger to life due to high voltages in the inverter!
• All work on the inverter may be carried out by qualified personnel only.
• T he a ppl iance is not to b e us ed b y ch ildren o r pe rso ns w ith re duced physical, sensory
or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction.
• Children should be supervised to ensure that they do not play with the appliance.
DANGER!
Danger of burn injuries due to hot enclosure parts.
• Do not touch enclosure during operation.
• Only touch the lid during operation.
NOTICE!
Dust and water in the Sunny Boy can damage the inverter!
Once the Electronic Solar Switch has been pulled out, the inverter only provides protection
rating IP21. The inverter is then no longer protected against water and dust. In order that
the protection rating IP65 is also provided during a temporary decommissioning, proceed
as follows:
• Release and disconnect all DC connectors.
• Open all DC connectors and remove the cables.
• Close all DC inputs with the corresponding DC connectors and the sealing plug
provided.
• Securely attach the Electronic Solar Switch again.
Installation Guide SB12-17-IA-en-52 11
Safety SMA Solar Technology AG
NOTICE!
Damage to the inverter due to moisture and dust intrusion
If the Electronic Solar Switch is not plugged in or incorrectly plugged in during operation,
moisture and dust can penetrate the inverter.
If the Electronic Solar Switch is not correctly plugged in, this can cause contacts to wear in
the Electronic Solar Switch or the Electronic Solar Switch might fall down. This can result in
yield loss and damage to the Electronic Solar Switch.
Always plug in the Electronic Solar Switch as described in the following:
• Do not tighten the screw in the Electronic Solar Switch.
• Firmly plug in the Electronic Solar Switch until it is flush with the enclosure.
• Ensure that the maximum distance between the Electronic Solar Switch and the
enclosure is 1 mm.
Grounding the PV Generator
Comply with the local requirements for grounding the modules and the PV generator.
SMA Solar Technology AG recommends connecting the generator frame and other
electricity conducting surfaces so that there is continuous conduction and to ground them
in order to achieve maximum protection of the system and personnel.

Mounting the Device SMA Solar Technology AG
4 Mounting the Device
4.1 Safety
DANGER!
Danger to life due to fire or explosion!
Despite careful construction, electrical devices can cause fires.
• Do not mount the inverter on flammable construction materials.
• Do not mount the inverter in areas where highly flammable materials are stored.
• Do not mount the inverter in areas with a risk of explosion.
CAUTION!
Danger of burn injuries due to hot enclosure parts.
• Mount the inverter in such a way that the enclosure cannot be touched inadvertently.
CAUTION!
Risk of injury due to the heavy weight of the inverter.
• Take the inverter's weight of approx. 25 kg into account for mounting.
4.2 Selecting the Mounting Location
Consider the following points when selecting where to install:
• The installation method and mounting location must be suitable for the inverter's weight and
dimensions (see section 11”Technical Data” (page63)).
• Mount on a solid surface.
• The mounting location must at all times be clear and have safe access without the use of
additional aids such as scaffolding or lifting platforms. Any possible service actions are
otherwise limited.
• Vertical installation or tilted backward by max. 45°.
• The connection area must point downward.
• Never install the device with a forward tilt.
16 SB12-17-IA-en-52 Installation Guide
SMA Solar Technology AG Mounting the Device
• Never install the device with a sideways tilt.
• Do not install horizontally.
• Install at eye level in order to allow operating state to be read at all times.
• To ensure optimal operation, the ambient temperature should be below 40 °C.
• Do not expose the inverter to direct sunlight to avoid a power reduction due to excessive
heating.
• I n a l ivi ng a rea, do n ot m oun t th e unit on pla ste rbo ard wal ls ( or s imilar) in o rde r to avo id a udible
vibrations. The inverter can make noises when in use which may be perceived as a nuisance in
a living area.
• Observe the minimum clearances to walls, other
inverters or objects as shown in the diagram in
order to ensure sufficient heat dissipation and
sufficient space for the removal of the Electronic
Solar Switch.
Multiple inverters installed in areas with high ambient temperatures
If necessary, increase the clearances and make sure there is enough ventilation to ensure
sufficient cooling of the inverters.

Mounting the Device SMA Solar Technology AG
4.3 Mounting the Inverter with Wall Mounting Bracket
CAUTION!
Risk of injury due to the heavy weight of the inverter.
• Take the inverter's weight of approx. 25 kg into account for mounting.
• When mounting the bracket, use fastening material suitable for the material.
1. Use the wall mounting bracket as a drilling template and mark the positions of the drill holes.
2. Attach the wall mounting bracket to the wall using
appropriate screws and washers.
18 SB12-17-IA-en-52 Installation Guide
SMA Solar Technology AG Mounting the Device
3. Use the upper mounting clips to fit the inverter in the
wall mounting bracket so that it cannot be pushed
out of the wall mounting bracket from the side.
4. If a second grounding conductor is required in the
country of installation, you need to ground the
inverter and secure it against being lifted out of
place, as described in section 5.2.3”Connecting
additional grounding” (page27).
5. . If a second grounding conductor is not required,
secure the inverter against being lifted out of place
using the enclosed M6x12 screw.
6. Check to ensure the inverter is firmly fastened.
☑ The inverter is now mounted to the wall.
