2 Safety
SMA Solar Technology AG
Operating Manual 7STP15-17TL-10-BE-en-10

Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the
DC conductors and the live components of the inverter. Touching the DC conductors or the live
components can lead to lethal electric shocks. If you disconnect the DC connectors from the
inverter under load, an electric arc may occur leading to electric shock and burns.
• Do not touch uninsulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed and commissioned only by qualified persons with the
appropriate skills.
• If an error occurs, have it rectified by qualified persons only.
• Prior to performing any work on the inverter, disconnect it from all voltage sources as
described in this document (see Section10 "Disconnecting the Inverter from Voltage
Sources", page48).
Danger to life due to electric shock
Touching an ungrounded PV module or array frame can cause a fatal electric shock.
• Connect and ground the PV modules, array frame and electrically conductive surfaces so
that there is continuous conduction. Observe the applicable local regulations.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• Do not touch any parts other than the lower enclosure lid of the inverter during operation.
Damage to the seal of the enclosure lids in subfreezing conditions
If you open the upper and lower enclosure lids in subfreezing conditions, the seals on the
enclosure lids can be damaged. This can lead to moisture entering the inverter.
• Do not open the inverter at ambient temperatures lower than -5°C.
• If a layer of ice has formed on the seal of the lid in subfreezing conditions, remove it prior to
opening the enclosure lids of the inverter (e.g. by melting the ice with warm air). Observe the

on supported SMA products, see www.SMA-Solar.com).
Speedwire/Webconnect
SMA Speedwire/Webconnect is a type of communication based on the Ethernet standard. This
enables inverter-optimized 10/100Mbit data transmission between Speedwire devices in PV
systems and the software Sunny Explorer. The Webconnect function enables direct data
transmission between the inverters of a small-scale system and the Internet portal SunnyPortal
without any additional communication device and for a maximum of four inverters per SunnyPortal
system. In large-scale PV power plants, data transmission to the Internet portal Sunny Portal is
carried out via the SMA Cluster Controller. You can access your SunnyPortal system from any
computer with an Internet connection.
4 Product Description SMA Solar Technology AG
Operating ManualSTP15-17TL-10-BE-en-1014

SMA Speedwire/Webconnect enables, for PV systems operated in Italy, the connection to or
disconnection of the inverter from the utility grid and definition of the frequency limits to be used
with IEC61850-GOOSE messages.
SMA Speedwire/Webconnect can be retrofitted.
RS485 interface
The inverter can communicate via cables with special SMA communication products via the RS485
interface (information on supported SMAproducts at www.SMA-Solar.com). The RS485 interface
can be retrofitted.
Grid Management Services
The inverter is equipped with service functions for grid management.
Depending on the requirements of the grid operator, you can activate and configure the functions
(e.g. active power limitation) via operating parameters.
SMA Power Control Module
The SMAPowerControlModule enables the inverter to implement grid management services and
is equipped with an additional multifunction relay (for information on installation and configuration,
see the installation manual of the SMAPowerControlModule). The SMAPowerControlModule
can be retrofitted.
Multifunction Relay
You can configure the multifunction relay for various operating modes. The multifunction relay is
used, for example, to switch fault indicators on or off (for information on installation and
configuration, see the installation manual of the multifunction relay). The multifunction relay can be
retrofitted.
SMAOptiTracGlobalPeak
SMAOptiTracGlobalPeak is an advancement of SMAOptiTrac and allows the operating point of
the inverter to follow the optimal operating point of the PV array (MPP) precisely at all times. In
addition, with the aid of SMAOptiTracGlobalPeak, the inverter can detect the presence of several
maximum power points in the available operating range, such as may occur particularly with
partially shaded strings. SMA OptiTrac Global Peak is enabled by default.
String-failure detection
String-failure detection recognizes the failure of an individual string or substring. If an insulation
error occurs, string-failure detection disconnects the defective string from the inverter. This avoids
having to shut down the entire PV array. In order for the string-failure detection to be reliable,
identically aligned PV modules must be connected to both inputs of the inverter. String-failure
detection is deactivated by default and must be activated.
Surge Arrester Type II
The surge arresters monitor the PV modules and limit dangerous overvoltages. Surge arresters of
typeII can be retrofitted.
4 Product Description
SMA Solar Technology AG
Operating Manual 15STP15-17TL-10-BE-en-10

Electronic string fuse
The electronic string fuse protects the PV array against potential reverse currents. The electronic
string fuse recognizes DC cables that were connected with reverse polarity or defective PV modules
and short-circuits the PV array. In order for the electronic string fuse function to be reliable, the
connection of the PV array must be made when there is sufficient irradiation. If the input voltage is
less than 188V, the protective function of the electronic string fuse is not active when the
connection is made.
QonDemand24/7
The inverter can supply reactive power by means of QonDemand24/7 covering the entire unit
circle around the clock.
IntegratedPlantControl
The inverter can display the Q(V) characteristic curve specified by the grid operator by means of
IntegratedPlantControl without measuring on the grid-connection point. The inverter can
automatically compensate equipment installed between the inverter and the grid-connection point.
