2.1 Appropriate usage

The Sunny WebBox with Bluetooth is a data logger that records, logs and makes available the data
of a PV plant via a user interface via the integrated web server. Additionally the Sunny WebBox with
Bluetooth can be used for remote diagnostics and the configuration of connected devices in a PV
plant via the computer.
The Sunny WebBox with Bluetooth allows all data of the connected devices to be continually
recorded and evaluated. During operation, the Sunny WebBox with Bluetooth records all values of
the PV plant every 2 minutes. Values of currently opened parameter groups are updated every 20
seconds. If the connection between the Sunny WebBox with Bluetooth and the PV plant is broken, the
Sunny WebBox with Bluetooth recreates the connection automatically, as soon as this is possible.
The Sunny WebBox with Bluetooth is integrated into the Bluetooth plant as a network forming device
(Master device). Network forming devices are principally communication products which form the
structure of the Bluetooth PV plant, collect, evaluate and process data.
The number of devices which the Sunny WebBox with Bluetooth can manage depends on the number
of master devices in the Bluetooth network with the same NetID. If the Sunny WebBox with Bluetooth
is the only Master in the Bluetooth network, the Sunny WebBox with Bluetooth can manage up to 50
devices. If 2 masters are present in the Bluetooth network (e.g. Sunny Explorer or the Sunny Beam
with Bluetooth), a maximum of 25 devices can be managed by the Sunny WebBox with Bluetooth.
A maximum of one Sunny WebBox with Bluetooth is allowed in a Bluetooth network with the same
NetID. Additional information about SMA Bluetooth Wireless technology can be found in the
download section at www.SMA.de/en.
The Sunny WebBox with Bluetooth is only to be operated using the supplied plug-in power supply
and in the voltage range intended for this.

occur through the use of the internet.
