Connection timeout

[dpmanter]

I have an solaredge inverter SE11400. I got it to communicate over modbus TCP using this script. I was even able to write values to a database for a day. However, during my fiddling with the settings it lost connection to the SolarEdge portal. Solaredge did some magic on their end and it now connects to the solar portal. However, now I can't get a connection over modbus TCP using this script. When I execute the script it says connected on the inverter LCD but it returns a timeout error (show below)

sunspec-status.pl -v target
Connection timed out
at /usr/local/share/perl/5.26.1/Device/Modbus/Client.pm line 82.

Any help would be appreciated.

Thanks,
Dave

More data..... if I use a modbus client application I can connect to the inverter using slave id = 2 and read the registers.

Does anyone know how to do this in the script? How do I call out slave id = 0?

With the status comment I believe you pass meter number?

Thanks Lloyd but using the option -m 1 or -m 2 doesn't work.

Looking at the Modbus frame

Slave ID | Function | Start PDU Register | Length | CRC
1 byte | 1 byte | 2 bytes | 2 bytes | 2 bytes

I need to set slave id to 0x02.

In the sunspec-status script if I change unit=>2 instead of unit=>1 it works. I had to change it in 4 places in the script.

I get a response from the inverter as follows:

@dpmanter you might want to ask solaredge to look at your inverter configuration then. We had a lengthy discussion to get data from the inverter and it was all fixed by an OTA update, see #4 (comment)
