SMA WEBBOX-BT-20 - Manual (Page 14)

Product Description SMA Solar Technology AG
14 SWebBox20-BA-en-13 User Manual
The Sunny WebBox has the function of a network-forming device (master device) in the Bluetooth
plant. Master devices are communication products that form the structure of the Bluetooth PV plant
and collect, evaluate and process data. Unlike other master devices, the Sunny WebBox can establish
up to five uplinks, i.e. it can directly connect with five devices at the same time. It can also assume the
function of a slave/root node and participate in establishing the Bluetooth network. In this way, the
Sunny WebBox can link together several groups of inverters that would otherwise have no Bluetooth
connection.
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 two masters are present in
the Bluetooth network (e.g. Sunny Explorer or Sunny Beam with Bluetooth), a maximum of 25 devices
can be managed by the Sunny WebBox. 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 area of www.SMA-Solar.com.
