2 Safety
2.1 Appropriate usage
The Sunny Boy is a PV inverter which converts the DC current of a PV generator into AC current and
feeds it into the public grid.
Principle of a PV System with this Sunny Boy
The inverter may only be operated with PV generators (PV modules and cabling) of protection class
II. Do not connect any sources of energy other than PV modules to the inverter.
Capacitive Discharge Currents
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 does not exceed
1,400 nF.
During grid feeding, a discharge current flows from the cells to ground. The amount of
current depends on the manner in which the modules are installed (e.g. foil on metal roof)
and on the weather (rain, snow). This "normal" discharge current may not exceed 50 mA
due to the fact that the inverter would otherwise automatically disconnect from the grid as
a protective measure. For further information on this subject, see the Technical Information
"Capacitive Discharge Currents" in the download area at www.SMA.de/en.

SMA Solar Technology AG Safety
Installation Guide SB30TL_40TL_50TL-IA-IEN120231 9
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 inverter.
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 inverter for purposes other than those described here. Alternative uses, modifications
to the inverter or the installation of components not expressly recommended or sold by
SMA Solar Technology AG void the warranty claims and operation permission.

locations according to customer requests, after evaluation by SMA Solar Technology AG.
You can make later modifications yourself by changing software parameters with respective
communication products (e.g. Sunny WebBox or Sunny Explorer). 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.

4 Mounting
4.1 Safety
4.2 Selecting the Mounting Location
Consider the following points when selecting where to install:
• The mounting method and location must be suitable for the inverter's weight and dimensions
(see section 13”Technical data” (page88)).
• 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.
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!
Parts of the enclosure can become hot - risk of burn injuries!
• Mount the inverter in such a way that it cannot be touched inadvertently during
operation.
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.

Mounting SMA Solar Technology AG
16 SB30TL_40TL_50TL-IA-IEN120231 Installation Guide
• Mount vertically or tilted backward by max. 15°.
• The connection area must point downwards.
• Never mount the device with a forward tilt.
• Never install the device with a sideways tilt.
• Do not mount horizontally.
• Mount at eye level to allow operating status to be read at all times.
• The ambient temperature should be below 40 °C to ensure optimal operation.
• Do not expose the inverter to direct sunlight to avoid power reduction due to excessive heating.
• In living areas, do not mount the unit on plasterboard walls or similar to avoid audible 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 removing the Electronic Solar
Switch.
Multiple inverters installed in areas with high ambient temperatures
There must be sufficient clearance between the individual inverters to ensure the cooling air
from the adjacent inverter flows freely.
If necessary, increase the clearance spaces and make sure there is enough ventilation to
ensure sufficient cooling of the inverters.

4.3 Mounting the Inverter with the Wall Mounting Bracket
1. Use the wall mounting bracket as a drilling template and mark the positions of the drill holes.
Number of drill holes used
• When mounting onto the wall, use at least 2 of the horizontal holes and the lowest
hole in the middle.
• Use the two holes in the center when mounting the device to a pillar.
