Webserver menu – Settings

In Settings you can configure the inverter and the external components (e.g. ripple control receiver etc.).

Basic settings

Set the general parameters of the inverter.

Inverter name

Set the general parameters of the inverter.

Parameter	Explanation
Inverter name	Input for inverter name (max. 63 characters). The following characters are permitted: a–z, A–Z, 0–9 and "-". Spaces or special characters are not possible. Following the name change the browser connection to the Webserver can be established with the new name or can continue using the IP address.

Time setting

Set time/date or select a time server.

Parameter	Explanation
Date and time	Input for time/date. The time can be taken from the PC.
Time zone	Setting the time zone
Use time server (NTP)	Activate/deactivate a time server (NTP server). After activation, the time from the time server is used. By using the NTP server, the switch between summer and winter time is also performed automatically.
NTP server	Input for IP address or name of NTP server (Network Time Protocol). Other, alternative NTP servers can be added via Plus (+). There are numerous free NTP servers on the network which can be used here.

Change password

Change Webserver password.

Parameter	Explanation
Change password	Change Webserver password. The password must comprise at least 8 characters and include the following characters: lower-case letters (a-z), upper-case letters (A-Z) and numbers (0-9).

Parameter

Explanation

Change password

Change Webserver password.

The password must comprise at least 8 characters and include the following characters:
lower-case letters (a-z), upper-case letters (A-Z) and numbers (0-9).

Network

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, subnet mask, router 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)

Set the inverter's network communication parameters for Wifi.

Parameter	Function
Wifi 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 on to the inverter to configure or monitor the inverter. SSID: Displays the inverter's SSID. The SSID is KOSTAL_<serial number> . 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.
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. 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.
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).

Modbus/SunSpec (TCP)

Activate the protocol, which can be used in the inverter to exchange data with external data loggers linked to the inverter via the LAN interface.

Parameter	Explanation
Activate Modbus	Output of the parameter port (1502) and the parameter ID (71) for Modbus/SunSpec. Activate the protocol on the LAN TCP/IP interface. Used for an external data logger, for example. Little-endian and big-endian can be chosen for the byte order. NOTE! KOSTAL devices and most partner applications use the default setting "little-endian". In some cases it may be necessary to change the byte order to "big-endian".
