2 Safety
Risk of burns due to hot enclosure parts
Some parts of the inverter enclosure can get hot during operation. Touching these enclosure parts
can result in burn injuries.
• Do not touch any parts other than the lower enclosure lid of the inverter during operation.
Damage to the inverter or the Speedwire/Webconnect data module due to electrostatic
discharge
The internal electronic components of the inverter or the Speedwire/Webconnect data module can
be irreparably damaged by electrostatic discharge.
• Ground yourself before touching any electronic component.

2.3 Operating Instructions

High costs possible due to inappropriate Internet tariffs
When using the Webconnect function, a constant Internet connection is required.
Depending on the quality of the Internet connection, the data transfer volume for an inverter is
between 150 MB and 550 MB per month. If the system overview in Sunny Portal with live data
display is used, there will be an additional data volume of 600 kB per hour.
• Since the Internet connection to Sunny Portal is permanent, time-based billing systems should
be avoided. High costs could be incurred. SMA recommends using an Internet flat rate.
If UMTS is used, VoIP is required
If UMTS is used, VoIP (Voice over IP) is required to use the Webconnect function.
• Make sure that the UMTS provider can also provide a VoIP service.
