Operating Manual 7SB13-21TL-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 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46).

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.

• During operation, do not touch any parts other than the enclosure lid of the inverter.

Risk of burns from hot heat sink

During operation, the heat sink at the top of the inverter can reach temperatures of over 70°C.

• Do not touch the heat sink.

• If the heat sink is soiled, clean it with a soft brush or a vacuum cleaner.

Operating ManualSB13-21TL-BE-en-118

SMA Solar Technology AG

2 Safety

Dust and water intrusion can damage the inverter.

If the inverter is equipped with an ESS, the inverter complies with degree of protection IP65 when the ESS is plugged in and the inverter is closed.

If the ESS is not plugged in, moisture and dust can penetrate and damage the inverter. In order to sufficiently protect the inverter during decommissioning, the DC inputs must be closed.

• Unlock and remove all DC connectors.

• Open all DC connectors.

• Close all DC inputs with the corresponding DC connectors and the supplied sealing plugs.

• Securely plug the ESS back in.

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.

Position Designation

A Type label

The type label uniquely identifies the inverter. You will require the information on the type label to use the product safely and when seeking customer support from the SMAServiceLine. You will find the following information on the type label:

• Device type (Model)

• Serial number (SerialNo.)

• Date of manufacture

• Device-specific characteristics

B LEDs

The LEDs indicate the operating state of the inverter (see Section9.2 "LED Signals", page44).

C ElectronicSolarSwitch (ESS)*

The ESS and the DC connectors together 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

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

Operating ManualSB13-21TL-BE-en-1114

SMA Solar Technology AG

4 Product Description

BLUETOOTH

Via BLUETOOTH, the inverter can communicate with various BLUETOOTH devices (for information on supported SMAproducts, see www.SMA-Solar.com). The BLUETOOTH interface can be retrofitted.

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 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.

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 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.

Fault indicator relay

The inverter is equipped with a fault indicator relay which will signal faults depending on the type of output device connected. You can connect your own load to this relay (e.g. warning light, acoustic signal) (see Section6.4 "Connecting the Fault Indicator Relay", page28).

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 Mounting

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.

☐ 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

Section11 "Technical Data", page48). ☐ 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48). ☐ 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.

5 Mounting

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.

Operating Manual 17SB13-21TL-BE-en-11

5 Mounting

Figure 4: Recommended clearances

SMA Solar Technology AG

Permitted and prohibited mounting positions:

☐ The inverter must be mounted in one of the permitted positions. This will ensure that no

moisture can penetrate the inverter. ☐ The inverter should be mounted in such way that display messages and LED signals can be

read without difficulty.
