Fronius Symo Hybrid 3.0-3-S - Network Administrator Information for System Monitoring; Network Requirements and Firewall Settings

General information for the network administrator
Requirements NOTE! Knowledge of networking systems is required in order to configure Fronius sys-
tem monitoring for the network.
If you are integrating Fronius system monitoring into an existing network, you must adapt
the address settings in line with the network.
e.g.: Network address space = 192.168.1.x, subnet mask = 255.255.255.0
- An IP address of between 192.168.1.1 and 192.168.1.254 must be assigned to
Fronius system monitoring.
- The selected IP address must not be in use on the network already.
- The subnet mask must match that of the existing network (e.g. 255.255.255.0).
If you want Fronius system monitoring to send service messages or to transmit data to
Fronius Solar.web, you must enter a gateway address and a DNS server address.
Fronius system monitoring uses the gateway address for the purpose of establishing an
Internet connection. An example of a suitable gateway address would be the IP address
of the DSL router.
IMPORTANT!
- Fronius system monitoring must never be assigned the same IP address as the PC/
laptop itself!
- Fronius system monitoring is not capable of connecting to the Internet on its own. In
the case of a DSL connection, a router has to establish the Internet connection.
General firewall
settings
DSL routers usually allow data to be sent over the internet and so do not normally have
to be configured for this purpose.
If existing firewall rules block the connection to the Fronius system monitoring function,
the following firewall rules must be added:
49049/UDP
output
80/TCP *)
Input
Sending of service messages x -
Ability to connect to Datamanager via Fronius
Solar.web
x -
Ability to connect to Datamanager via Fronius
Solar.access or Fronius Solar.service
- x
Ability to access the Datamanager web page - x
Configure the firewall so that data can be sent from the Fronius system monitoring IP
address to port 49049/UDP of "fdmp.solarweb.com".
*) We recommend only allowing access to the web interface of the Fronius system monit-
oring function from secure networks. If internet access is absolutely necessary (e.g. for
service purposes within a defined time period), configure the network router in such a
way that requests for any external port are redirected to port 80/TCP.
Caution - the inverter will therefore be visible on the internet and at will be at an
increased risk of network attacks.
