Network

Set the inverter's network communication parameters.

LAN

Set the inverter's network communication parameters for LAN.

Parameter	Explanation
Automatically acquire IPv4 address	If the box is ticked, the IP address is generated automatically by a DHCP server. Most routers provide a DHCP server as standard. NOTE! The option "Automatically acquire IP address" is activated by default. This means that the inverter obtains its IP address from a DHCP server.
IPv4 address (only with manual configuration)	Enter the IP address of the inverter NOTE! If the inverter is not allocated an IP address automatically through a DHCP server, the inverter can be configured manually. NOTE! The data necessary for configuration, such as IP addresses, subnet mask, router addresses and DNS addresses, can be found on your router/gateway.
Subnet mask (only with manual configuration)	Enter the subnet mask, e.g. 255.255.255.0
Router/gateway (only with manual configuration)	Enter the IP address of the router
DNS server 1 (only with manual configuration)	Enter the IP address of the DNS server (Domain Name System)
DNS server 2 (only with manual configuration)	Enter the IP address of the backup DNS server (Domain Name System)

WLAN

Set the inverter's network communication parameters for WLAN.

Parameter	Function
WLAN settings	Setting the communication parameters for the inverter's Wifi connection. The inverter offers various options here.
Wifi mode: Wifi off The inverter's Wifi interface is deactivated.
Wifi mode: Access point The inverter offers a Wifi access point. This can be used, for example, to log a PC or smartphone in to the inverter to configure or monitor the inverter. SSID: Displays the inverter's SSID. The SSID consists of KOSTAL_ and the inverter's serial number, e.g. KOSTAL_91109ADE00053. SSID visible: The SSID is visible to other devices in the Wifi search. Encryption: Select Wifi encryption. Password: Enter a password. By default, this is the article number found on the type plate. Radio channel: Select the radio channel. By default, this should be set to "Auto". QR code: Displays the data as a QR code. Scan the code with a smartphone and connect to the inverter. The network data is displayed under the QR code and is provided by the inverter as an access point. IPv4 address: Inverter IP address. If there are problems with the standard IP address, another one can be entered here. Subnet mask: Configured subnet mask value. Router/Gateway: IP address for the internal gateway (192.168.67.1). DNS Server 1: IP address for the DNS server (192.168.67.1). DNS server 2: IP address for the backup DNS server (192.168.67.1). DHCP IP address allocation – from-to: Indicates the IP address range allocated for devices connected to the inverter. Validity: After the set minutes have expired, the access point is deactivated.
WLAN mode: Client The inverter is a Wifi client and can connect to a Wifi gateway in the local home network. In that case, a LAN connection no longer needs to be set up. Bridge Mode: If there are several KOSTAL inverters in a system, the inverter can be used as a WLAN bridge to the existing WLAN router. Other inverters, energy meters or battery storage units can be connected via LAN cable to the inverter serving as a WLAN bridge to establish a connection to the local home network and beyond. Find networks: Press the button to search for available networks in the vicinity of the inverter. The available networks in the vicinity of the inverter are then displayed. Select your local network to which the inverter should connect. SSID: If the network you are looking for is not displayed, this may be because it has been configured to not be visible. You can then enter the network name yourself here. Password: Enter the password for the network you are looking for here. Automatically acquire IPv4 address: If the box is ticked, the IP address is generated automatically by a DHCP server. Most routers provide a DHCP server as standard. For manual configuration, you can assign the data yourself.
DHCP server	The DHCP service is automatically activated when LAN Mode > Access Point is started and no other DHCP service has been detected in the network. The DHCP service is deactivated when the LAN mode is changed or switched off. IP address allocation: Enter the IP range (start-end) and the validity (period 1-28 days).
