Connection in the local network

7.4.1.1 Access addresses for the product in the local network

DHCP Server is recommended
The DCHP server automatically assigns the appropriate network settings to your nodes in the
local network. A manual network configuration is therefore not necessary. In a local network,
the Internet router is usually the DHCP server. If the IP addresses in the local network are to be
assigned dynamically, DHCP must be activated in the Internet router (see the Internet router
manual). In order to receive the same IP address by the internet router after a restart, set the
MAC address binding.
In networks where no DHCP server is active, proper IP addresses must be assigned from the
free address pool of the network segment to all network participants to be integrated during
commissioning.
Communication disturbances in the local network
The IP address range 192.168.12.0 to 192.168.12.255 is occupied for communication
amongst SMA products and for direct access to SMA products.
Communication problems might occur if this IP address range is used in the local network.
• Do not use the IP address range 192.168.12.0 to 192.168.12.255 in the local network.
If the product is connected to a local network (e.g. via an Internet router or Wi-Fi), the product will
receive a new IP address. Depending on the type of configuration, the new IP address will be
assigned automatically by the DHCP server (Internet router) or manually by you.
Upon completion of the configuration, the product can only be reached via the listed access
addresses in the local network:
• Generally applicable access address: IP address manually assigned or assigned by the DHCP
server (Internet router) (identification via network scanner software or network configuration of
the Internet router).
• Access address: https://SMA[serial number] (e.g. https://SMA0123456789)

7.4.1.2 Ports for data communication in the local network

In small local networks the use of certain ports is unrestricted. In industrial networks, the use of these
ports may require authorization from the system administrator. For proper operation, the outgoing
Internet connection must allow the use of the following ports and URLs:
Port and URL
Port 21 (FTP)
Port 80 and 443 (http/https)
update.sunnyportal.de
Port 123 (NTP)
