IMPORTANT SAFETY INFORMATION
NOTICE
Manipulation of system data in networks
You can connect the supported SMA products to the Internet. When connected to the Internet, there is a risk that unauthorized users can access and manipulate the data of your system.
- Set up a firewall.
- Close unnecessary network ports.
- If absolutely necessary, only enable remote access via a virtual private network (VPN).
- Remote access must only be permitted via a secure connection.
- Do not use the port forwarding feature. This also applies to the used Modbus ports.
NOTICE
Damage of SMA products due to cyclical changing of parameters
The parameters of SMA products that can be changed with writable Modbus registers (RW) are intended for long-term storage of device settings. Cyclical changing of these parameters leads to destruction of the flash memory of the SMA products.
Parameters for grid management services to control and limit the nominal PV system power are an exception. Such parameters (system control objects) may be changed cyclically.
- Do not change device parameters cyclically.
- Use the parameters for grid management services for the automated remote control of the PV system.
Communication disturbances in the local network
The IP address range 192.168.12.0 to 192.168.12.255 is reserved for the SMA-internal data exchange and cannot be used for system communication within the local network.
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.
Requirements in the documents enclosed with each product must be observed.
