2 Safety

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 Section9 "Disconnecting the Inverter from Voltage Sources", page40).

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 seals on the enclosure lids in subfreezing conditions

If you open the upper and lower enclosure lids when temperatures are below freezing, the enclosure seals 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 when temperatures are below freezing, 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.

Position Designation

F DC load-break switch

The inverter is equipped with a DC load-break switch. If the DC loadbreak switch is set to the position I, it establishes a conductive connection between the PV array and the inverter. Setting the DC load-break switch to the O position interrupts the DC electric circuit and completely disconnects the PV array from the inverter. Disconnection takes place at all

poles. G Lower enclosure lid H Upper enclosure lid

4.3 Interfaces and Functions

The inverter can be equipped or retrofitted with the following interfaces and functions:

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 10/100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 4 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.

Webconnect enables - for PV systems operated in Italy - the connection or disconnection of the inverter to or from the utility grid and the specifying of the frequency limits to be used via IEC61850-GOOSE messages.

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 and can be used in place of the SMASpeedwire/Webconnect interface in the inverter.

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.

Operating ManualSTP20-25TL-BE-en-1214

SMA Solar Technology AG

4 Product Description

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 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.

Surge arrester type II

Surge arresters limit dangerous overvoltages. Surge arresters of typeII can be retrofitted (for details on the installation refer to the service manual of the inverter at www.SMA-Solar.com).

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 (for details on the configuration refer to the Technical Information "IntegratedPlantControl and QonDemand24/7" at www.SMA-Solar.com).

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 after having activated the function (for information on the system configuration refer to the Technical Information "IntegratedPlantControl and QonDemand24/7" at www.SMA-Solar.com).

5 Mounting

SMA Solar Technology AG

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. ☐ 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10 "Technical Data", page43).

☐ 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.

☐ 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10 "Technical Data", page43).
