2.3 Safety Precautions
STSatz_Sicherh_Einleitungssatz
This section contains safety precautions that must be observed at all times when working on or with
the product.
To prevent personal injury or property damage and to ensure long-term operation of the product,
read this section carefully and follow all safety precautions at all times.
SiHiw_Stromschlag durch hohe Spannung
SiHiw_nicht geerdetes PV-Modul
Danger to life due to high voltages in the inverter
The inverter should be mounted, installed and commissioned by qualified persons only.
This also applies to troubleshooting.
• Always operate the inverter in a closed state.
• Do not touch exposed cable ends.
• Have the inverter mounted, installed and commissioned by qualified persons only.
• If an error occurs, have it rectified by qualified persons.
Danger to life due to high voltages
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.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Prior to performing any work on the inverter, disconnect it from all voltage sources, as described
in this document (see Section 10, page 47).
Danger to life due to electric shock
Touching an ungrounded PV module or an 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.

SMA Solar Technology AG 2 Safety
SiHiw_Vor Berühren erden
Damage to the seal of the enclosure lid during sub-zero conditions
If you open the upper and lower enclosure lid during sub-zero conditions, the seal of the enclosure
can be damaged. As a result, moisture can penetrate 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 sub-zero conditions, remove it prior to
opening the inverter (e.g. by melting the ice with warm air). Observe the applicable safety
regulations.
Damage to the inverter due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter through electrostatic
discharge.
• Ground yourself before touching any components.
Damage to the display or the type label due to the use of cleaning agents
• If the inverter is dirty, clean the enclosure, the cooling fins, the enclosure lid, the type label,
the display, and the LEDs using only water and a cloth.

DElectronic Solar Switch (ESS)*
The ESS and the DC connectors form a DC load-break switch. When plugged
in, the ESS forms a conductive path between the PV array and the inverter.
Removing the ESS interrupts the DC electric circuit and removing all DC
connectors disconnects the PV array completely from the inverter.

4.2 Interfaces and Functions
Bluetooth
The inverter can communicate via Bluetooth with various Bluetooth devices (information on supported
SMA products at www.SMA-Solar.com).
RS485
The inverter can communicate with SMA communication products via the RS485 interface
(information on supported SMA products at www.SMA-Solar.com). The RS485 interface can be
retrofitted.
Speedwire/Webconnect
Speedwire is a type of communication based on Ethernet allowing you to connect the inverter to a
Speedwire network. Webconnect allows for data exchange between the inverter and Sunny Portal.
Sunny Portal is an Internet portal which allows you to monitor PV systems and visualize and present
PV system data. The Speedwire/Webconnect data module can be retrofitted.
Multifunction relay
You can configure the multi-function relay for various operating modes. The multi-function relay is used,
for example, to switch fault indicators on or off (for information on installation and configuration,
see installation manual of the multi-function relay). The multi-function relay can be retrofitted.
The product is suitable for outdoor installation.
RAL quality mark for solar products
The product complies with the requirements of the German Institute for
Quality Assurance and Certification.
Certified safety
The product is VDE-tested and complies with the requirements of the
German Equipment and Product Safety Act.
C-Tick
The product complies with the requirements of the applicable Australian
EMC standards.

SMA Solar Technology AG 4 Product Description
SMA Power Control Module
The SMA Power Control Module enables the inverter to implement grid management and is equipped
with an additional multi-function relay (for information on installation and configuration, see the
SMA Power Control Module installation manual). The SMA Power Control Module can be retrofitted.
Fan retrofit kit
The fan retrofit kit is used for additional inverter cooling at high ambient temperatures and also has a
multi-function relay (for information on installation and configuration, see the fan retrofit kit installation
manual). The fan retrofit kit can be retrofitted, and it cannot be operated in parallel with the
SMA Power Control Module.
SMA OptiTrac Global Peak
SMA OptiTrac Global Peak is a further development of the SMA OptiTrac and allows the operating
point of the inverter to follow the MPP precisely at all times. SMA OptiTrac Global Peak also means
that the inverter can detect the presence of multiple maximum power points in the available operating
range, such as can occur in partially shaded PV strings in particular.
Grid management services
The inverter is equipped with grid management functions.
Depending on the requirements of the grid operator, you can activate and configure the functions
(e.g. active power limitation) via operating parameters.
All-pole sensitive residual-current monitoring unit
The all-pole sensitive residual-current monitoring unit detects alternating and direct differential
currents. The integrated differential current sensor detects the current difference between the neutral
conductor and the number of line conductors for single-phase and three-phase inverters. If the current
difference increases suddenly, the inverter disconnects from the utility grid.

5.1 Requirements for Mounting
Requirements for the mounting location:
WaHiw_Lebensgefahr durc h Feuer oder Explos ion
☐ 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 inside the home, the inverter will develop 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 Section 13 "Technical Data", page 53).
☐ Climatic conditions must be met (see Section 13 "Technical Data", page 53).
☐ The ambient temperature must be below 40°C to ensure the optimal operation of the inverter.
☐ The mounting location should be clear 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.
☐ 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.
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.
• Do not mount the product in potentially explosive atmospheres.

Recommended clearances:
Provided that the recommended clearances are observed, adequate heat dissipation will be ensured
as well as sufficient space to remove the ESS if necessary. Sufficient heat dissipation prevents a
reduction in inverter power as a result of high temperatures (details on temperature derating can be
found in the Technical Information "Temperature Derating" at www.SMA-Solar.com).
☐ Observe 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.
