2.1 Intended Use
The Sunny Boy is a PV inverter which converts the DC current of the PV array to AC current and feeds
it into the power distribution grid. The Sunny Boy is suitable for use with fuel cells, small wind turbine
systems, and other DC current sources. You can use the AC electricity generated as follows:
Interconnection Code Compliance
The Sunny Boy has been checked by the certification body and certified according to the guidelines
in UL 1741 Static Inverters and Charge Controllers for use in Photovoltaic Power Systems, IEEE 929-
2000 Recommended Practice for Utility Interface of Photovoltaic Systems, and IEEE 1547 Standard
for Interconnecting Distributed Resources with Electric Power Systems.
UL 1741 is the standard used for the Sunny Boy by the certification body in order to
certify that it complies with the regulations of the National Electrical Code® and
IEEE 929-2000. IEEE 929-2000 states recommendations regarding the appropriate
equipment and functionality that is required to guarantee fault-free operation when the
power generation is connected to the power distribution grid.
The Sunny Boy is also certified in accordance with Canadian Electrical Code® CSA
C22.2 N0. 107.1-01 (General Use Power Supplies).
Household grid: Energy flows into the household grid. The loads connected, for example
household devices or lighting, consume the energy. The energy left over is
fed into the power distribution grid. When the Sunny Boy is not generating
any energy, e.g. at night, the loads that are connected are supplied by the
power distribution grid.
The Sunny Boy does not have its own energy meter. When energy is being
fed into the power distribution grid, the energy meter runs in reverse.
Power distribution grid: Energy is fed directly into the power distribution grid. The Sunny Boy is
connected to a separate energy meter. Depending on the electric utility
company, you will be remunerated accordingly for the energy generated.
Stand-alone grid: The Sunny Boy is connected to a stand-alone grid. A stand-alone grid is a
grid that is not connected to a power distribution grid. The Sunny Boy needs
a grid-forming generator, for example, a Sunny Island, in order to function.
The energy generated is consumed directly on site, surplus energy can be
stored in batteries.
Prior to designing and installing your PV plant, contact the local grid operator or the
responsible authority.

Principle of a PV Plant with a Sunny Boy
The Sunny Boy may only be operated with PV arrays (modules and cabling) that have protective
insulation. Do not connect any energy sources other than PV modules to the Sunny Boy.
PV plant design
When designing the PV plant, ensure that the values comply with the permitted operating range of all
component parts at all times. Use the free of charge "Sunny Design" at www.SMA-America.com to
design your PV plant.

G Power distribution grid
Leading Leakage Currents
PV modules with large capacities relative to ground, such as thin-film PV modules, may only be
used if their coupling capacity does not exceed 2 µF.
During feed-in to the grid, a leakage current flows from the cells to ground. The amount of
current depends on how the modules are installed and on the weather. This leakage current
may not exceed 50 mA since otherwise the inverter will automatically disconnect from the grid.
The Sunny Boy 6000TL-US, 7000TL-US, 8000TL-US, 9000TL-US, 10000TL-US and
11000TL-US is a transformerless inverter.
It has no galvanic isolation.
The PV modules must be rated for at least the maximum PV plant voltage.

2 Safety SMA America, LLC
14 SB6-11TL-US-IA-en-13 Installation Manual
Grounding the PV modules
This Sunny Boy is a transformerless inverter. That is why it has no galvanic isolation. Do not ground
the DC electric circuits of the PV modules connected to the Sunny Boy. Only ground the mounting
frame of the PV modules.
If you connect grounded modules to the Sunny Boy, the error message F-Riso is displayed.
The DC electric circuit is connected to the AC grid during operation.
Fuses
The Sunny Boy and the DC-Disconnect do not contain string fuses.
According to the National Electrical Code® of 2008, Section 690.35, string fuses are necessary in
order to protect the PV plant against reverse currents.
Arc-Fault Circuit Interrupter AFCI
Only the following Sunny Boy types are equipped with an automatic arc-fault circuit interrupter
(AFCI):
• SB 6000TLUS-12
• SB 7000TLUS-12
• SB 8000TLUS-12
• SB 9000TLUS-12
• SB 10000TLUS-12
• SB 11000TLUS-12
The 2011 edition of the National Electrical Code®, Section 690.11, stipulates that newly installed
PV plants attached to a building must be fitted with a means of detecting and disconnection of serial
electric arcs (AFCI) on the PV side.
An electric arc with a power of 300 W or greater must be interrupted by the AFCI in the time specified
by UL 1699B. A tripped AFCI may only be reset manually.
The arc-fault circuit interrupter (AFCI) can be deactivated in the "Installer" mode via the
communication device if this function is not desired.

2.2 Safety Precautions
High voltages in the inverter
Electric shock when touching live components.
• Prior to performing any work on the inverter, disconnect the inverter from any voltage sources.
• Only connect the inverters as described in this manual.
• Only electrically qualified persons may work on the inverter.
The inverter can become hot during operation
• Burn injuries may be possible when touching the enclosure.
• During operation, touch the enclosure lid only.
The Sunny Boy may down over due to inappropriate transport
Contusions or bone fractures due to the heavy weight of the Sunny Boy.
• Prior to transporting the Sunny Boy, take its weight of 77 lb. (35 kg) into consideration.
• Use suitable lifting techniques for the transport.
