Setting Up Access Via The Internet - SMA FUEL SAVE CONTROLLER 2.0 Instrucciones De Uso

5 Getting Started
Parameter Description
Time interval Time interval to which the system time of the Fuel Save Controller is to
be synchronized via the SNTP server
Start SNTP server Activates the use of the Fuel Save Controller as an SNTP server
If the SNTP server of the Fuel Save Controller is activated, the SNTP
server specifies the system time for other devices in the photovoltaic
diesel hybrid system. In these devices, SNTP must be activated and
the IP address of the Fuel Save Controller must be entered as an
SNTP server.
Procedure:
1. Open the Plant Overview menu via the page and menu selection.
2. Open the General Settings menu via the page and menu selection.
3. Set the parameter UTC time zone offset according to the local time zone (see Section 4.8.3, page 20).
4. Carry out the following steps to arrange for the system time to be specified automatically:
• Activate the Use SNTP client checkbox.
• Set the parameters Address of SNTP server and Time interval to the desired values.
5. Carry out the following steps in order to set the system time manually:
• Deactivate the Use SNTP client checkbox.
• Set the parameters Date and Time to the desired values.
6. In order to set the Fuel Save Controller for use as an SNTP server for other devices, activate the Start SNTP
server checkbox.
7. Select the [Apply] button.

Setting Up Access via the Internet

In order to provide quick assistance in the event of a disturbance, Service requires access to the operating data of the
PV diesel hybrid system. Access to the operating data enables a detailed analysis of the existing error and therefore
speeds up troubleshooting.
The Fuel Save Controller is prepared to establish a secure VPN connection to Service. The VPN connection is based on
the IPsec protocol and is established by the FSC router (router in the Fuel Save Controller). To allow smooth operation
of the Fuel Save Controller, access from the local network of the PV system operator to the Fuel Save Controller is only
permitted for the following applications:
• FTP interface to the Fuel Save Controller via port 21 of the TCP protocol
• Web browser for the user interface of the Fuel Save Controller via port 80 of the TCP protocol
• Interface of the Fuel Save Controller to the SCADA system via port 502 of the TCP protocol
The FSC router enables these applications by means of port forwarding via the system router (router in the PV system
operator's local network with access to the Internet).
Ensure data security in networks
When accessing via the Internet, there is a risk that unauthorized users may access and manipulate the data or
devices in your system. Appropriate protective measures can include the following:
• Set up a firewall.
• Close unnecessary network ports.
• Only enable remote access via VPN tunnel.
• Do not set up port forwarding at the communication port in use.
