2 Safety
2.1 Appropriate Usage
The Sunny Tripower is a PV inverter which converts the direct current of a PV array into alternating
current and feeds this into the power distribution grid.
Principle of a PV plant with this Sunny Tripower
The Sunny Tripower may only be operated with PV arrays (PV modules and cabling) of protection
class II. Do not connect any sources of energy other than PV modules to the Sunny Tripower.
When designing the PV plant, ensure that the values comply with the permitted operating range of all
components at all times. The free design program "Sunny Design" from version 2.0
(www.SMA.de/en/SunnyDesign) will assist you in this. The manufacturer of the PV modules must
have approved the PV modules for use with this Sunny Tripower. 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" at www.SMA.de/en).
String connections Sunny Tripower 8000TL, 10000TL and 12000TL
The Sunny Tripower 8000TL, 10000TL and 12000TL only have 4 string connections at
input A.
Leakage Currents
PV modules with large capacities relative to ground, such as thin-film PV modules with cells
on a metallic substrate, are only to be implemented if their coupling capacity does not
exceed 2.55 μF.
During feed-in operation, a leakage current flows from the cells to ground, the size of which
depends on the manner in which the PV modules are installed (e.g., foil on metal roof) and
on the weather (rain, snow). This "normal" leakage 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.

Product Description SMA Solar Technology AG

3 Product Description
The Sunny Tripower is a multi-string inverter which converts the direct current of a PV array into
alternating current. To do this, the Sunny Tripower is equipped with 2 separate MPP trackers which
can be connected to the different PV modules. Feed-in of the electricity into the power distribution grid
is three-phase. Cooling is carried out by the cooling system OptiCool, whereby a fan is integrated on
the underside and on the left side of the enclosure.
In addition, Sunny Tripower is equipped with the features described below.
3.1 Surge Arrester Type II
Along with the standard integrated, thermally monitored varistors, the Sunny Tripower is equipped
with module slots for the additional mounting of surge arresters Type II. The modules are monitored
when plugged in. If a module is triggered, a warning is issued via the display or external
communication (e.g. Sunny WebBox or Sunny Explorer). This makes it easy to integrate the
Sunny Tripower into a lightning protection concept. The necessary modules are available as retrofit
kits for input A or input A+B.

SMA Solar Technology AG Product Description
Installation Manual STP8-17TL-IA-IEN112030 15
3.2 Intelligent String Failure Detection
The Sunny Tripower is equipped with a system that recognizes the total failure of individual strings or
partial strings (see following figure). With a PV module current of approx. 1 A, monitoring of up to 6
partial strings per string input is possible. Identical alignment of the connected PV array at input A and
B is prerequisite for the reliable functioning of the intelligent string failure detection. For the education
phase, the Sunny Tripower needs approximately 14 days of moderate irradiation after successful
activation. One advantage of this system is that its auto-adaptive function completely eliminates the
necessity of any configuration. In the event of a string failure a warning message is issued on the
display or via external communication (e.g. Sunny WebBox or Sunny Explorer). Note that extreme
shading and snow covered PV modules lead to warning messages.

Product Description SMA Solar Technology AG
16 STP8-17TL-IA-IEN112030 Installation Manual
3.3 Electronic String Fuse
The Sunny Tripower is equipped with an electronic string fuse. It prevents dangerous reverse currents
in the PV array and thus plays a key role in fire prevention. Reverse currents can occur if connections
are reverse poled during installation or as a result of module defects during operation. The electronic
string fuse recognizes these defects and shorts the PV array. This prevents the occurrence of reverse
currents and thus safeguards both the PV plant and the Sunny Tripower. An advantage of this method
is that conventional fuses at the DC inputs are not necessary. The electronic solution is entirely
maintenance-free and does not require any dimensioning.
In order to use this function optimally, the greatest of attention is necessary during commissioning (see
section 6.4"Connecting the PV Array (DC)" (page32)). The Sunny Tripower warns of dangerous
conditions by beeping and issuing warnings in the display or via external communication. If electrical
installation takes place under conditions of insufficient irradiation (PV voltage smaller than 188 V), the
Sunny Tripower will not have power supply which means that the protective functions described
above will not be active during installation.
3.4 Reactive Power Feed-in and Grid Management
The Sunny Tripower is capable of utilizing reactive power and can feed reactive power into the grid
via the setting of a default value for the displacement power factor (cos φ). Additionally this inverter
is also equipped with advanced grid management functions, e.g. power limitation and dynamic grid
support. These functions can be activated and configured depending on the requirements of the utility
operator.
You will find detailed information on the setting parameters of these functions in the Technical
Description "Reactive power feeding and grid stability management" in the download area at
www.SMA.de/en in the "Technical Description" category of the respective inverter.

Danger of burn injuries due to hot enclosure parts
• Mount the inverter in such a way that it cannot be touched inadvertently.

Mounting SMA Solar Technology AG
20 STP8-17TL-IA-IEN112030 Installation Manual
• Mount vertically or tilted backwards by max. 15°.
• The connection area must point downward.
• Never mount the device with a forward tilt.
• Never install the device with a sideways tilt.
• Do not mount horizontally.
• Install the inverter at eye level. Given the weight of the device, this will facilitate disassembling
if service work is necessary.
• The ambient temperature should be below 40 °C to ensure optimum operation.
• Do not expose the inverter to direct solar irradiation, as this can cause excessive heating and
power reduction.
• In living areas, do not mount the unit on plasterboard walls or similar to avoid audible vibrations.
When in use, the inverter emits noises 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 that the
cooling air of the adjacent inverter is not taken in.
If necessary, increase the clearance spaces and make sure there is enough fresh air supply
to ensure sufficient cooling of the inverters.
