SMA Solar Technology AG Safety
2 Safety
2.1 Appropriate Usage
The Sunny Boy is a PV inverter which converts the DC current of a PV generator to AC current and
feeds it into the public grid.
Principle of a PV system with this Sunny Boy
Input A
Distribution
Input B
Sunny Boy
PV module
Input B
Input B is only available on the Sunny Boys 4000TL and 5000TL.
Public grid
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 flows from the cells to ground. The magnitude of this current
depends on the manner in which the modules are installed and, to no small extent, on the weather
(rain, snow). This operational leakage current is not to exceed 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
take n (see also Technical Information "Module Techn ology", in the download area of www.SMA.de).
Installation Guide SB30TL_40TL_50TL-IEN085120 9
Safety SMA Solar Technology AG
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 invalidates the warranty claims and operation permission.
Authorized Countries
The Sunny Boys 3000TL / 4000TL / 5000TL meet, with the corresponding settings, the requirements
of the following standards and guidelines (as at 12/2008):
• VDE 0126-1-1 (02.2006)
• DK 5940 Ed. 2.2 (02.2006) (Certification of Sunny Boy 3000TL still in process)
• RD 1663/2000 (2000)
• PPC (06.2006)
• AS4777 (2005)
• EN 50438 (12.2007)
Upon request, SMA Solar Technology can set network parameters in-house according to customer
specifications for other countries / installation locations, once these have been tested by SMA Solar
Technology.
You can subsequently make adjustments via changes to the software parameters using relevant
communications products (e.g. Sunny Data Control). For this, however, a personal password is
required, which you can receive from the SMA Serviceline upon request.

2.2 Safety Instructions
DANGER!
Danger to life due to high voltages in the Sunny Boy!
• All work on the Sunny Boy must only be carried out by a qualified electrician.
CAUTION!
Danger of burn injuries due to hot housing parts!
During operation, the upper cover of the housing and the housing body may become hot.
• Only touch the lower housing cover during operation.
CAUTION!
Possible health risks due to the effects of radiation!
• Do not remain within a distance of less than 20 cm from the Sunny Boy for long
periods of time.
Grounding the PV generator
Comply with the local requirements for grounding the modules and the PV generator.
SMA Solar Technology recommends connecting the generator frame and other electricity
conducting surfaces such that there is continuous conduction and to connect them to the
ground in order to reach maximum protection for property and persons.

4.1.2 Ambient Conditions
• The mounting location and mounting method must be suitable for the weight and dimensions.
• Mount on a solid surface.
• The mounting location must be accessible at all times.
• The ambient temperature should be below 40 °C at all times to guarantee optimal operation.
• Do not expose the Sunny Boy to direct sunlight, in order to avoid power reduction due to
excessive heating.
• In a living area, do not mount the unit on
plasterboard walls etc. in order to avoid audible
vibrations.
The Sunny Boy can make noises when in use which
can be considered a nuisance when installed in a
living area.
