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.

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.

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).

Operating ManualSTP20-25TL-BE-en-1224

SMA Solar Technology AG

6 Electrical Connection

☐ Insulation stripping length: 12 mm ☐ The cable must be dimensioned in accordance with the local and national directives for the

dimensioning of cables. The requirements for the minimum wire size derive from these directives. Examples of factors influencing cable dimensioning are: nominal AC current, type of cable, routing method, cable bundling, ambient temperature and maximum desired line losses (for calculation of line losses, see the design software "SunnyDesign" from software version2.0 at www.SMA-Solar.com).

Load-break switch and cable protection:

Damage to the inverter due to the use of screw-type fuses as load-break switches

Screw-type fuses (e.g. DIAZED fuse or NEOZED fuse) are not load-break switches.

• Do not use screw-type fuses as load-break switches.

• Use a load-break switch or circuit breaker as a load disconnection unit (for information and design examples, see the Technical Information "Circuit Breaker" at www.SMA-Solar.com).

☐ In PV systems with multiple inverters, protect each inverter with a separate three-phase circuit

breaker. Make sure to observe the maximum permissible fuse protection (see Section10 "Technical Data", page43). This will prevent residual voltage being present at the corresponding cable after disconnection.

☐ Loads installed between the inverter and the circuit breaker must be fused separately.

Residual-current monitoring unit:

☐ If an external residual-current device is required, install a residual-current device which trips at

a residual current of 100mA or higher (for details on selecting a residual-current device, see the Technical Information "Criteria for Selecting a Residual-Current Device" at www.SMASolar.com).

Overvoltage category:

The inverter can be used in grids of overvoltage categoryIII or lower in accordance with IEC60664-1. That means that the inverter can be permanently connected to the grid-connection point of a building. In case of installations with long outdoor cabling routes, additional measures to reduce overvoltage categoryIV to overvoltage categoryIII are required (see the Technical Information "Overvoltage Protection" at www.SMA-Solar.com).

The inverter is not equipped with a grounding conductor monitoring device. In order to guarantee safety in accordance with IEC62109, you must take one of the following measures:

• Connect a grounding conductor made of copper wire with a cross-section of at least 10mm² to the connecting terminal plate for the AC cable.

• Connect additional grounding with the same cross-section as the connected grounding conductor to the connecting terminal plate for the AC cable (see Section6.3.3 "Connecting Additional Grounding", page28). This prevents touch current if the grounding conductor at the connecting terminal plate for the AC cable fails.

Connection of additional grounding

In some countries, additional grounding is generally required. In each case, observe the locally applicable regulations.

• If additional grounding is required, connect an additional grounding that has at least the same cross-section as the connected grounding conductor to the connecting terminal plate for the AC cable (see Section6.3.3, page28). This prevents touch current if the grounding conductor at the connecting terminal plate for the AC cable fails.

6.3.2 Connecting the Inverter to the Utility Grid

Requirements:

☐ The connection requirements of the grid operator must be met. ☐ The grid voltage must be in the permissible range. The exact operating range of the inverter is

specified in the operating parameters.

Procedure:

1. Disconnect the circuit breaker from all three line conductors and secure against reconnection.

2. If the lower enclosure lid is mounted, loosen all screws of the lower enclosure lid using an Allen key (AF3) and lift the enclosure lid from below and remove it.

3. Remove the adhesive tape from the enclosure opening for the AC cable.

4. Insert the cable gland from the outside into the enclosure opening and tighten it from the inside with the counter nut.

5. Route the AC cable into the inverter through the cable gland. If necessary, slightly loosen the swivel nut of the cable gland.

6. Dismantle the AC cable.

7. Shorten L1, L2, L3 and N by 5mm each.

8. Strip off the insulation of L1, L2, L3, N and PE by 12mm.

9. Push the safety levers of the AC connecting terminal plate right up to the stop.

10.

Risk of fire if two conductors are connected to one terminal

If you connect two conductors to a terminal, a fire can occur due to a bad electrical connection.

• Never connect more than one conductor per terminal.

11.

Danger of crushing when locking levers snap shut

The locking levers close by snapping down fast and hard.

• Press the locking levers of the connecting terminal plate for the AC cable down with your thumb only.

• Do not grip the entire connecting terminal plate for the AC cable.

• Do not place your fingers under the locking levers.

12. Connect PE, N, L1, L2 and L3 according to the labeling to the connecting terminal plate for the AC cable and push the safety levers down. The direction of the rotating magnetic field of L1, L2 and L3 is not relevant.

13. Make sure that all conductors are securely in place.

6.3.3 Connecting Additional Grounding

If additional grounding or equipotential bonding is required locally, you can connect additional grounding to the inverter. This prevents touch current if the grounding conductor at the terminal for the AC cable fails. The required clamping bracket, the screw and the conical spring washer are part of the scope of delivery of the inverter.

Cable requirement:

Use of fine-stranded conductors

You can use an inflexible or a flexible, fine-stranded conductor.

• When using a fine-stranded conductor, it has to be double crimped by a ring terminal lug. Make sure that no insulated conductor is visible when pulling or bending. This will ensure sufficient strain relief by means of the ring terminal lug.

☐ Grounding cable cross-section: 16mm² at maximum

Procedure:

1. Strip the grounding cable insulation.

2. Lead the clamping bracket over the grounding cable. Arrange the grounding cable on the lefthand side.

3. Screw the clamping bracket tight using the M6x16 cylindrical screw and the conical spring washer M6 (torque: 6Nm). The teeth of the conical spring washer must face the clamping bracket.

6.4 DC Connection

connectors (for information on assembling DC connectors, see the DC connector installation manual).

☐ The negative connection cables of the PV modules must be fitted with the negative DC

connectors (for information on assembling DC connectors, see the DC connector installation manual).

Use of Y adapters for parallel connection of strings

The Y adapters must not be used to interrupt the DC circuit.

• Do not use the Y adapters in the immediate vicinity of the inverter. The adapters must not be visible or freely accessible.

• In order to interrupt the DC circuit, always disconnect the inverter as described in this document (see Section9, page40).

6.4.2 Connecting the PV Array

Destruction of the inverter due to overvoltage

If the open-circuit voltage of the PV modules exceeds the maximum input voltage of the inverter, the inverter can be destroyed due to overvoltage.

• If the open-circuit voltage of the PV modules exceeds the maximum input voltage of the inverter, do not connect any strings to the inverter and check the design of the PV system.

Destruction of the measuring device due to overvoltage

• Only use measuring devices with a DC input voltage range of 1,000 V or higher.

Damage to the DC connectors due the use of contact cleaner of other cleaning agents

Some contact cleaners or other cleaning agents may contain substances that decompose the plastic of the DC connectors.

default settings, type label or display

Section7.2, page32

Set the country data set appropriate for your country or purpose within the first tenfeed-in hours via the rotary switches in the inverter. After the first ten feed-in hours, the country data set can only be changed by means of a communication product.

The country data set must be set correctly.

If you select a country data set which is not valid for your country and purpose, it can cause a disturbance in the PV system and lead to problems with the grid operator. When selecting the country data set, you must always observe the locally applicable standards and directives as well as the properties of the PV system (e.g. PV system size, grid-connection point).

• If you are not sure which country data set is valid for your country or purpose, contact your grid operator for information on which country data set is to be configured.

Operating ManualSTP20-25TL-BE-en-1232

SMA Solar Technology AG

Country data set for operation with external decoupling protection

When operating the PV system with external decoupling protection, the inverter has the additional country data set Medium-Voltage Directive (Germany) or MVtgDirective. This country data set allows you to extend the operating range of the inverter for voltage and frequency. This country data set should only be selected if the PV system is disconnected via external decoupling.

• If the country data set for operation is set with external decoupling protection, only operate the inverter with an external three-phase decoupling protection. Without external three‑phase decoupling protection, the inverter will not disconnect from the utility grid when the country-specific standard requirement is exceeded.

Procedure:

1. Determine the rotary switch position for your country and purpose. Call up the Technical Information "Overview of the Rotary Switch Settings" at www.SMA-Solar.com.

Danger to life due to high voltages

• Ensure that the inverter is disconnected from all voltage sources and that the enclosure lid is removed (see Section9, page40).

3. Set the rotary switches A and B to the required position using a flat-blade screwdriver (blade width: 2.5mm).
