• Ensure that no voltage is present and wait 5 minutes before touching any parts of the PV
system or the product.
DANGER
Danger to life due to electric shock in case of overvoltages and if surge
protection is missing
Overvoltages (e.g. in the event of a flash of lightning) can be further conducted into the building
and to other connected devices in the same network via the network cables or other data cables
if there is no surge protection. Touching live parts and cables results in death or lethal injuries due
to electric shock.
• Ensure that all devices in the same network are integrated in the existing overvoltage
protection.
• When laying the network cable outdoors, ensure that there is suitable surge protection at
the network cable transition from the product outdoors to the network inside the building.

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).
• Do not use the port forwarding feature. This also applies to the used Modbus ports.
• Disconnect system components from other network components (network segmentation).
NOTICE
High costs due to inappropriate Internet tariff
Depending on use, the data volume of the product transferred via the Internet may vary in size.
The data volume depends, for example, on the number of devices in the system, the frequency of
device updates, the frequency of data transfer to SunnyPortal or the use of FTP push. High costs
for the Internet connection can be the result.
• SMA Solar Technology AG recommends using an Internet flat rate.
NOTICE
Damage to the product due to cleaning agents
The use of cleaning agents may cause damage to the product and its components.
• Clean the product and all its components only with a cloth moistened with clear water.
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.
The country data set must be set correctly.
If you select a country data set which is not valid for your country and purpose, it can cause a
disturbance in the PV system and lead to problems with the grid operator. When selecting the
country data set, you must always observe the locally applicable standards and directives as
well as the properties of the PV system (e.g. PV system size, grid-connection point).
• If you are not sure which standards and directives are valid for your country or purpose,
contact the grid operator.
