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 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 applicable safety regulations.

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).

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.

Operating ManualSTP15-17TL-10-BE-en-1014

SMA Solar Technology AG

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.

4 Product Description

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.

Operating Manual 15STP15-17TL-10-BE-en-10

4 Product Description

SMA Solar Technology AG

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.

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 inverter in areas containing highly flammable materials or gases.

• Do not mount the inverter in a potentially explosive atmosphere.

☐ Do not mount the inverter on a pillar. ☐ 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, 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

Section11 "Technical Data", page50). ☐ 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 Section11 "Technical Data", page50). ☐ 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.
