2 Safety
SMA Solar Technology AG
Operating manual EVC22-3AC-20-BE-en-10 15
High ambient temperature
Safety mechanisms are implemented in the charging station to protect the product against
damage due to too high ambient temperatures. For this process, the charging rate of the
charging station is gradually reduced (derating). The charging rate depends on the operating
temperature.
• Wait until the operating temperature drops.
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.
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.
