Network diagnostics

The inverter allows the connection to the Internet orKOSTAL Solar Portal to be checked using the Traceroute and Ping commands.

Parameter	Explanation
Diagnostic tool	Ping Determines the path to a specific host by sending ICMP (Internet Control Message Protocol) echo request messages with different TTL (Time to Live) values to the target. Each gateway along the path must decrement the TTL in an IP packet by at least 1 before it is forwarded. In fact, the TTL is a maximum connection counter. When the TTL of a packet reaches 0, the gateway is expected to return an ICMP Time Exceeded response to the inverter. Traceroute Determines the path by sending the first echo request message with a TTL of 1 and increasing the TTL by 1 on each subsequent transmission until the target responds or the maximum number of hops is reached. The maximum number of hops is 20 by default and can be specified in the Traceroute max. TTL field. The path is determined by examining the ICMP timeout messages returned by intermediate gateways and the echo response message returned by the target. However, some gateways do not return Time Exceeded messages for packets with expired TTL values and are not visible to the Traceroute tool. In this case, a row of asterisks (*) is displayed for this hop.
IP address/website	Enter IP address or domain name, e.g. www.kostal-solar-portal.de
Ping count	Number of echo requests sent (1-50)
Ping packet size	Number of data bytes being sent (4-1472 bytes)
Ping timeout	Wait time for a response in milliseconds (100-2000 ms)
Traceroute max. TTL	Maximum number of hops (maximum TTL to be reached) in the path to search for the target (10-30)
