2.1 Intended Use
The Speedwire/Webconnect Piggy-Back is a Speedwire communication interface with Webconnect
function for inverters.
Speedwire is a cable-based type of communication based on the Ethernet standard and the
communication protocol SMA Data2+. This enables inverter-optimised 10/100 Mbit data
transmission between Speedwire devices in PV plants.
The Webconnect function enables data transmission between a small plant and the Internet portal
Sunny Portal. In Sunny Portal, a maximum of four inverters can be combined in a Sunny Portal plant.
In Italy, the Speedwire/Webconnect Piggy-Back can be used for plants up to 6 kW that are
connected to the low-voltage grid. The Speedwire/Webconnect Piggy-Back implements grid
management for one inverter. The Speedwire/Webconnect Piggy-Back also receives specifications
fr om t he n etw ork ope rator vi a Et her net (in acc ord anc e with st andard CEI 0-21). The network operator
sends the control signals to the Speedwire/Webconnect Piggy-Back via a network operator gateway.
The Speedwire/Webconnect Piggy-Back fulfils the following tasks:
• Set-up of a Speedwire network in small and large-scale PV plants
• Data exchange with Sunny Portal:
– in small plants via a router with Internet connection
– in large-scale PV plants via the Cluster Controller
• Data exchange with Sunny Explorer
• Additionally for Italy:
– Implementation of grid management for one inverter
–Active power limitation of the connected active power
– Remote shutdown within 50 ms
– Narrowing of the frequency limits to between 49.5 Hz and 50.5 Hz
– Automatic narrowing of the inverter frequency limits to between 49.5 Hz and 50.5 Hz
when the connection to the network operator gateway is interrupted
The Speedwire/Webconnect Piggy-Back is available as a retrofit kit.
The inverter still complies with the standard after the product has been installed.

2 Safety SMA Solar Technology AG
The Speedwire/Webconnect Piggy-Back must only be operated with supported products
(see Section 2.2).
For safety reasons, it is not permitted to modify the product or install components that are not explicitly
recommended or distributed by SMA Solar Technology AG for this product.
The enclosed documentation is an integral part of this product.
• Read and observe the documentation.
• Keep the documentation in a convenient place for future reference.
Only use the Speedwire/Webconnect Piggy-Back in accordance with the information provided in the
enclosed documentation. Any other use may result in personal injury or property damage.
2.2 Supported Products
SMA inverter
The Speedwire/Webconnect Piggy-Back must only be used in the following inverters with at least the
given firmware version:
Sunny Boy / Sunny Mini Central From firmware version
SB 1300TL-10, SB 1600TL-10, SB 2100TL 4.30
SB 3300-11, SB 3800-11 4.02
SMC 6000A-11 4.33
SMC 7000HV-11 2.21
Firmware updates on the inverters can only be carried out by SMA Service. If your inverter is in need
of a firmware update, contact the SMA Service Line (see Section 10).

2.3 Qualifications of Skilled Persons
The work described in this document must be performed by 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 directives
• Knowledge of how an inverter works and is operated
• Knowledge of and adherence to this document and all safety precautions

2.4 Safety Precautions
Electric Shock
Lethal voltages are present in the conductive parts of the inverter.
• Prior to performing any work on the inverter, disconnect the inverter from any voltage sources
on the AC and DC sides (see inverter installation manual). Observe the waiting time to allow
the capacitors to discharge.
Burn Hazards
Some parts of the inverter enclosure can get hot during operation.
• During operation, touch the inverter on the enclosure lid only.
Environmental Influences
When close d and wi th the E SS plugged i n, 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 plugged in, the inverter must be protected against dust and water.
• Firmly plug ESS in again after performing any work on the inverter.
2.5 Operating Information
Selecting a Suitable Internet Tariff for Small Plants
When using the new Webconnect function, a constant Internet connection is required.
De pen din g on the qu ali ty o f the Int ern et c onn ect ion , th e transm ission volume for an inverter is between
150 MB and 550 MB per month. When using the plant overview in Sunny Portal with live data
display, there is an additional data volume of 600 kB per hour.
• SMA recommends using an Internet tariff with a flat rate.
• Since Sunny Portal is permanently connected to the Internet, time-based billing systems should
be avoided. High costs could be incurred.
