2.3 Operating Instructions
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 due to electrostatic discharge
The internal components of the inverter can be irreparably damaged by electrostatic discharge.
• Ground yourself before touching any inverter component.
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. When using the system overview in Sunny Portal with
live data display, there is an additional data volume of 600 kB per hour.
• Since there is a permanent Internet connection to Sunny Portal, time-based billing systems
should be avoided. High costs could be incurred. SMA Solar Technology AG 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.
• Ensure that the UMTS provider also provides the VoIP service.
