3.1 Appropriate Usage
The server-based 32-bit application compiles the instantaneous values of your PV plant for up to 50
Sunny WebBox devices and makes this data externally available to OPC Clients via OPC Data
Access and OPC XML-DA. Parameters of the PV plant can also be modified via the SMA OPC Server
(see section 6.4.3”Changing Parameters via the OPC Client” (page25)). The SMA OPC Server
supports all Sunny WebBox devices with firmware version 1.46, and later.
Transfer to third parties, use or duplication of the software without a valid license is prohibited.
Violations will be prosecuted.
3.2 Safety Instructions
• Using the software you can change the safety-related parameters of SMA inverters. Incorrectly
set parameters can damage or destroy the inverter. Do not alter these safety-relevant
parameters without prior consultation with your electric power company operating the grid into
which your plant feeds.
