Installation Manual SWebBox20-IA-en-12 13
Product Description SMA Solar Technology AG
The Sunny WebBox has the function of a grid-forming device (master device) in the Bluetooth plant.
Master devices are communication products which 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, meaning that it can directly connect to five devices simultaneously. It can also assume
the function of a slave/root node and be involved in establishing a Bluetooth network. In this way,
the Sunny WebBox can connect multiple groups of inverters to one another that would not otherwise
have had a 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 netw ork (e. g. S unn y Exp lor er o r Sun ny B eam wit h 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 at www.SMA-Solar.com.

5.2 Determining the Mounting Location for Bluetooth PV Plants
5.2.1 Information on SMA Bluetooth
The devices in your PV plant can communicate and network with a communication device via
Bluetooth. To ensure that the devices communicate with each other and are interlinked, they have to
be set to the same NetID. The NetI D is a un iqu e identi fic ati on n umber of you r PV pla nt. Thus , th e Ne tID
distinguishes your PV plant from other PV plants.
Determining the NetID for your PV plant
If your PV plant does not yet have a NetID, you must first determine a free NetID using the
Sunny Explorer software and set this for your devices in the PV plant.
NetID 1 is currently not supported by the Sunny WebBox with Bluetooth
It is currently only possible to establish a direct connection to an individual SMA Bluetooth
device via NetID 1 using the Sunny Explorer software or the Sunny Beam with Bluetooth.
Change the NetID of the Sunny WebBox with Bluetooth to the NetID of your PV plant
(NetID 2 to NetID F).
5.2.2 Determining the Mounting Location
Before you mount the Sunny WebBox, check the connec tion quality between the Sunny WebBox and
your PV plant at the intended mounting location of the Sunny WebBox. The connection quality can
be checked using the Sunny Explorer or the Sunny Beam with Bluetooth (see the user manual of the
respective device). You can change the connection quality by reducing and increasing the distance
between the Bluetooth devices.
5.2.3 Extending the Bluetooth Network with the SMA Bluetooth Repeater
The SMA Bluetooth Repeater transmits the data traffic within a Bluetooth network. If you install the
SMA Bluetooth Repeater on the limit of the radio range, the SMA Bluetooth Repeater extends the
range of the Sunny WebBox. Thus you can also connect remote devices via Bluetooth.

6.6 Configuring Sunny WebBox for the Local Network
Information on Integrating the Sunny WebBox into a Local Network
Protecting the Ethernet network from external attacks
Protect your Ethernet network through suitable security measures such as a firewall and
through the allocation of secure passwords (see the Sunny WebBox user manual). After
the first login to the Sunny WebBox, please change the passwords for each user group.
You have the following options for integrating the Sunny WebBox into the local network:
Changing network settings
Do not change any network settings in the network devices if you are not clear about the
effects of the change. Changes to values could lead to the existing network not functioning
or only partially functioning. If you have any questions, contact your network administrator.
• Using dynamic network settings (DHCP)
• Making static network settings
6.6.1 Using Dynamic Network Settings (DHCP)
When using DHCP (Dynamic Host Configuration Protocol), the Sunny WebBox obtains its network
settings (IP address, subnet mask, gateway and DNS server) via a DHCP server.
Default settings
DHCP is activated in the Sunny WebBox by default.
DHCP server requirements
If you want to obtain the network settings for the Sunny WebBox via DHCP, check your
DHCP server in advance. The DHCP server must extend the lease of the assigned IP
address. If the DHCP server assigns a new IP address after the lease has expired, we do
not recommend using DHCP.
You can only call up the user interface via the URL http://WebBox"serial number" if
your DHCP server has a DNS function.
If your DHCP server does not have a DNS function but you want to use DHCP, you can
call up the user interface via the current IP address of the Sunny WebBox. You can
determine the current IP address via the SD card (see page 43). Alternatively, you can find
the Sunny WebBox IP address in the DHCP server. A DHCP server can normally list all
devices to which you have assigned an IP address. You can then identify the
Sunny WebBox based on your MAC address. The MAC address is located on the type
label of the Sunny WebBox.
