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 non-insulated 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.
Danger to life due to high voltages in the inverter
Touching live components within the inverter can lead to lethal electric shocks. Some components
also require at least five minutes to discharge after the inverter has been disconnected from
voltage sources.
• Do not open the inverter.
Danger to life due to electric shock
Touching an ungrounded PV module or array frame can cause a lethal electric shock.
• Connect and ground the PV modules, array frame and electrically conductive surfaces so

4Product Description SMA Solar Technology AG
Operating ManualSB15-25-1VL-40-BE-en-1116

WLAN
The inverter is equipped with a WLAN interface as standard. The inverter is delivered with the
WLAN interface activated as standard. If you do not want to use WLAN, you can deactivate the
WLAN interface.
In addition, the inverter has a WPS (WiFi Protected Setup) function. The WPS function connects the
inverter automatically with an end device (e.g. smartphone, tablet PC or computer). You can
activate the WPS function by tapping on the enclosure lid twice in quick succession. The open
interface will then be signalized via the rapid flashing of the blue LED on the inverter.
Limited function in the event of frost
The integrated WLAN interface is only designed for temperatures down to -20°C.
• Deactivate the WLAN interface at low temperatures (see Section9.14 "Switching WLAN
On and Off", page57).
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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 detects 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.
All-pole sensitive residual-current monitoring unit
The all-pole sensitive residual-current monitoring unit detects alternating and direct differential
currents. In single-phase and three-phase inverters, the integrated differential current sensor detects
the current difference between the neutral conductor and the line conductor(s). If the current
difference increases suddenly, the inverter disconnects from the utility grid.
Connection of the SMAEnergyMeter
If an SMAEnergyMeter is installed in the PV system, the inverter can receive data on the
household energy consumption directly from this.

5 Mounting
5.1 Requirements for Mounting
Requirements for the mounting location:
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires.
• Do not mount the product in areas containing highly flammable materials or gases.
• Do not mount the product in potentially explosive atmospheres.
☐ Do not mount the inverter on a pillar.
☐ The mounting location must be suitable for the weight and dimensions of the inverter (see
Section15 "Technical Data", page85).
☐ The mounting location must not be exposed to direct solar irradiation. Direct solar irradiation
can result in the premature aging of the exterior plastic parts of the inverter and direct solar
irradiation can cause the inverter to overheat. When becoming too hot, the inverter reduces
its power output to avoid overheating.
☐ The mounting location should be freely and safely accessible at all times without the need for
any auxiliary equipment (such as scaffolding or lifting platforms). Non-fulfillment of these
criteria may restrict servicing.
☐ To ensure optimum operation, the ambient temperature should be between -25°C and
+40°C.
☐ Climatic conditions must be met (see Section15 "Technical Data", page85).
Permitted and prohibited mounting positions:
☐ The inverter must only be mounted in one of the permitted positions. This will ensure that no
moisture can penetrate the inverter.
☐ The inverter should be mounted in such a way that LED signals can be read without difficulty.
