2.1 Appropriate Usage
The Sunny WebBox is a data logger that records, logs and makes available the data of a PV plant
via a user interface through the integrated Web server. Additionally, the Sunny WebBox can be used
for remote diagnostics and the configuration of connected devices in a PV plant via the computer.
With the Sunny WebBox, all data of the connected devices can be continually recorded and
evaluated. During operation, the Sunny WebBox 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 and the PV plant is broken, the Sunny WebBox with Bluetooth restores
the connection automatically, as soon as this is possible.
The Sunny WebBox 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, and collect, evaluate and process data.
The number of devices which the Sunny WebBox can manage depends on the number of master
devices in the Bluetooth network with the same NetID. If the Sunny WebBox is the only Master in the
Bluetooth network, the Sunny WebBox can manage up to 50 devices. If there are 2 masters present
in the Bluetooth network (e.g. Sunny Explorer or Sunny Beam), a maximum of 25 devices can be
managed by the Sunny WebBox. A maximum of one Sunny WebBox is allowed in a Bluetooth
network with the same NetID. Additional information about SMA Bluetooth Wireless Technology can
be found in the download area at www.SMA-America.com.
The Sunny WebBox is only to be operated using the supplied plug-in power supply and in the voltage
range intended for it.
Do not use the data from Sunny WebBox for billing purposes. Additional costs can be incurred from
the use of the Internet.
The Sunny WebBox is only to be used with original accessories or with accessories recommended by
SMA.
Only use the Sunny WebBox exclusively for the purposes described in the manual.
Carefully read the documentation related to the Sunny WebBox before you commission the
Sunny WebBox.
Also refer to the technical data of the Sunny WebBox.
