Network

Set the inverter's network communication parameters.

The settings for the inverter’s LAN or Wifi connection can be configured here.

For a Wifi connection, you can choose between a client connection where the inverter connects to a Wifi router via Wifi or an access point where the inverter itself provides a Wifi network which other devices can then use to connect to the inverter in order to access it.

LAN settings

Set the inverter's network communication parameters for LAN. The inverter is connected directly to a router via a LAN cable.

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)

Wifi settings

Set the communication parameters for the inverter's Wifi connection. The inverter offers various modes here.

Wifi mode – off

The inverter's Wifi interface is deactivated.

Parameter	Function
Status	WLAN is switched off.
WLAN mode	Off

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.

Parameter	Function
Bottlenecks	Displays the connection quality to the WLAN gateway.
WLAN mode	Access point
SSID	Displays the inverter's SSID. The SSID consists of KOSTAL_ and the inverter's serial number, e.g. KOSTAL_91109ADE00053.
Password	Enter a password. By default this is the article number starting with P that can be found on the type plate.
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.
Advanced settings – access point Here the settings for the inverter access point can be changed manually.
SSID visible	The name of the inverter Wifi network is set to visible by default. You can deactivate this here.
Encryption	Select an encryption.
Radio channel	The default value of auto does not have to be changed.
IPv4 address	IP address at which the inverter access point can be reached.
Subnet mask	The default value does not have to be changed.
Router/gateway	The default value does not have to be changed.
DNS server 1	The default value does not have to be changed.
DNS server 2	A second DNS server is not required.

LAN settings in combination with WLAN access point

We would recommend not changing these settings.

Parameter	Function
Automatically acquire IPv4 address	If the box is ticked, the inverter can be used as a WLAN bridge. Other devices connected to the inverter via LAN are assigned an IP address via the inverter’s DHCP server. (Default) If Automatically acquire IPv4 address is deactivated, the WLAN bridge is deactivated. The following data can now be assigned manually for the inverter so that the inverter can also be contacted via a LAN connection.
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).

Wifi 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.
If there are several KOSTAL inverters in a system, the inverter can be used as a Wifi bridge to the Wifi gateway. Additional inverters, energy meters or battery storage can be connected to this inverter using LAN cables to establish the connection to the local home network and the Internet.

Parameter	Function
Bottlenecks	Displays the connection quality to the WLAN gateway.
Search wireless 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 WLAN IP address is generated automatically by an external DHCP server. Most routers provide a DHCP server as standard. If Automatically acquire IPv4 address is deactivated, the following data must be assigned manually.
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).

DNS server 2	IP address for the backup DNS server (192.168.67.1).

Wifi - LAN bridge

The Wifi - LAN bridge can be used in the Access Point and Client Wifi modes. Further devices can be connected to the LAN interface of the inverter, which serves as a Wifi - LAN bridge. Data is sent on to the router and across the Internet via the Wifi interface. In this case, devices connected to the inverter must not be connected to another DHCP server via which they could receive network data (e.g. IP addresses).

Parameter	Function
Enabling packet forwarding between Wifi and LAN	The Wifi bridge is activated by default. You can deactivate it here should you wish to. If there is no DHCP server in the network, the Wifi bridge is activated by plugging in a LAN cable and establishing the connection to another inverter or similar device. If an inverter has already been integrated into a local network via LAN and has received network data via another DHCP server, the Wifi bridge is not activated.
