2 System Overview
2.1 Sunny WebBox RPC
The data loggers Sunny WebBox and Sunny WebBox with Bluetooth continuously record all the data
of a PV plant. This is then averaged over a configurable interval and cached. The data can be
transmitted at regular intervals to the Sunny Portal for analysis and visualization.
Via the Sunny WebBox and Sunny WebBox with Bluetooth RPC interface, selected data from the
PV plant can be transmitted to a remote terminal by means of an RPC protocol (Remote Procedure
Call protocol).
To do this, the Sunny WebBox provides a pool of service procedures (see Section 6 "Object
Definitions", page 12) that can be accessed from the remote terminal by means of a Remote
Procedure Call protocol (RPC protocol) via a network or RAS connection. The data exchange format
used here is the JavaScript Object Notation (JSON) (see Section 3 "JavaScript Object Notation",
page 7).
2.2 Differences between Sunny WebBox and Sunny WebBox with
Bluetooth
Different representation for Sunny WebBox and Sunny WebBox with Bluetooth
