2.1 Intended Use

The Webconnect Data Module is a Webconnect communication interface for inverters based on the
SMA Speedwire technology.

Speedwire is a cable-based type of communication based on the Ethernet standard and the
communication protocol SMA Data2+. This enables inverter-optimised 100 Mbit data transmission
between Speedwire devices in PV plants.

The Webconnect function enables data transmission between the Internet portal Sunny Portal and the
inverters. Data transmission takes place via a router with Internet access. A PC with the software
Sunny Explorer* is also connected to the router.

* as of software version 1.04. Sunny Explorer is available free of charge at www.SMA-Solar.com.

The Webconnect Data Module performs the

following tasks:

• Set-up of a Speedwire network

• Data exchange with the Internet portal Sunny Portal and Sunny Explorer via a router

A plant in Sunny Portal can consist of a maximum of four inverters with installed Webconnect Data
Module. The Speedwire network can be set up optionally with the following topologies:

•Linear topology

• Star topology

Figure1: PV plant with a Speedwire network in linear topology (example)

2 Safety SMA Solar Technology AG

Figure2: PV plant with a Speedwire network in star topology (example)

The Webconnect Data Module is provided as a retrofit kit or is pre-installed in the inverter.
The Webconnect Data Module must only be installed in the following inverters as of firmware version

2.51:

• Sunny Boy 2500TLST-21 / 3000TLST-21 / 3000TL-21 / 3600TL-21 / 4000TL-21 /

2.2 Qualification of Skilled Persons

The tasks described in this document are intended for skilled persons only. Skilled persons must have
the following qualifications:

• Training in the installation and commissioning of electrical devices and plants

• Knowledge of how to deal with the dangers and risks associated with installing and using
electrical devices and plants

• Knowledge of all applicable standards and guidelines

• Knowledge of how an inverter works and is operated

• Familiarity with this document and adherence to all safety precautions

2.3 Safety Precautions

Electric Shock

Lethal voltages are present in the conductive parts of the inverter.

• Prior to performing work on the inverter, disconnect the inverter from any voltage sources on the
AC and DC sides (see inverter installation manual).

Burn Hazards

Some parts of the inverter enclosure can get hot during operation.

• During operation, only touch the inverter on the enclosure lid.

Environmental Influences

When closed and with the ESS attached, the inverter has the degree of protection IP65. The inverter
is thus protected against dust intrusion and water penetration. Dust intrusion and water penetration
can damage the inverter.

• If the ESS is not attached, the inverter must be protected against dust and water.

• Firmly attach the ESS again after performing any work on the inverter.

Electrostatic Discharge

By touching electronic components, you can damage or even destroy the inverter through electrostatic
discharge (ESD).

• Earth yourself before touching any inverter components.

5.3 Installing the Webconnect Data Module in the Inverter

2. Loosen the screw of the display far enough so that
the display can be flipped up.

3. Flip up the display until it clicks into place.

Interference of network data transmission due to AC cables

When AC cables are in operation, they generate an electromagnetic field which may induce
leading or lagging interference in network cables during data transmission.

• Lay the network cables using suitable fastening material and with a minimum clearance
of 50 mm to the AC cables.

1.

Danger to life due to electric shock when opening the inverter

Death or serious injuries

• Disconnect the inverter from voltage sources on the AC and DC sides and open it

Data Module is correctly plugged into the centre connector
strip in the inverter.

The inverter does not recognise the Webconnect Data Module.

Corrective measures:

• Update the inverter firmware (download the update file
from www.SMA-Solar.com).

Firewall or IP filter settings are not correct.

Corrective measures:

• Adjust firewall or IP filter settings (see firewall or router
manual).
