Operating Manual 9SB30-50TL-21-BE-en-11
2 Safety
SMA Solar Technology AG
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 (see Section10 "Disconnecting the Inverter from Voltage
Sources", page45).
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
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 display or the type label due to the use of cleaning agents
• If the inverter is dirty, clean the enclosure, the enclosure lid, the type label, the display and
the LEDs with a damp cloth only.

4.2 Interfaces and Functions
The inverter can be equipped or retrofitted with the following interfaces and functions:
BLUETOOTH
Via BLUETOOTH, the inverter can communicate with various BLUETOOTH devices (for information
on supported SMA products, see www.SMA-Solar.com).
SMA Speedwire/Webconnect
The inverter is equipped with SMA Speedwire/Webconnect as standard. SMA Speedwire/
Webconnect is a type of communication based on the Ethernet standard. This enables inverteroptimized 10/100Mbit 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 SunnyPortal without any additional
communication device and for a maximum of four inverters per SunnyPortal system. In large-scale
PV power plants, data transmission to the Internet portal SunnyPortal is carried out via the
SMAClusterController. You can access your SunnyPortal system from any computer with an
Internet connection.
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.
RS485 interface
The inverter can communicate via cables with special SMA communication products via the RS485
interface (information on supported SMAproducts 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.
Operating Manual 15SB30-50TL-21-BE-en-11
4 Product Description
SMA Solar Technology AG
SMA Power Control Module
The SMAPowerControlModule 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 SMAPowerControlModule). The SMAPowerControlModule
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.
Fan retrofit kit
The fan retrofit kit is used for additional inverter cooling at high ambient temperatures and also has
a multifunction relay (for information on installation and configuration, see the installation manual of
the fan retrofit kit). The fan retrofit kit can be retrofitted and must not be operated in parallel with the
SMAPowerControlModule.
SMAOptiTracGlobalPeak
SMAOptiTracGlobalPeak is an advancement of SMAOptiTrac 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 SMAOptiTracGlobalPeak, 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.
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.

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 inverter in areas containing highly flammable materials or gases.
• Do not mount the inverter in a potentially explosive atmosphere.
☐ The mounting location must be inaccessible to children.
☐ A solid support surface must be available for mounting, e.g. concrete or masonry. When
mounted on drywall or similar materials in the living area, the inverter emits audible vibrations
during operation which could be perceived as annoying.
☐ The mounting location must be suitable for the weight and dimensions of the inverter (see
Section11 "Technical Data", page47).
☐ To ensure optimum operation, the ambient temperature should be between -25°C and 40°C.
☐ The mounting location should not be exposed to direct solar irradiation. Direct solar irradiation
can cause the inverter to overheat. As a result, the inverter reduces its power output.
☐ Climatic conditions must be met (see Section11 "Technical Data", page47).
☐ 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.

Dimensions for mounting:
SMA Solar Technology AG
Figure 3: Position of the anchoring points
Recommended clearances:
If you maintain the recommended clearances, adequate heat dissipation will be ensured. Thus, you
will prevent power reduction due to excessive temperature.
☐ Maintain the recommended clearances to walls as well as to other inverters or objects.
☐ If multiple inverters are mounted in areas with high ambient temperatures, increase the
clearances between the inverters and ensure sufficient fresh-air supply.
