1500 XS, FW 1.53.50 not working #25

Hello Marcel,

I tried several Py test scripts. None of them will respond. I was able to send this: echo "WIFIKIT-214028-READ" | nc -v -u -n -b 192.168.178.130 48899

I got the the serial numer back. I understand from your comments this is only the Wifi part talking back. Nothing comes back from port 8899. I was able to setup the SEMS portal. (SolarGo is NOT working and says the function is not supported by this device) I made a tcpdump and concluded that 8899 or even 48899 was not even used by SEMS. Could it be that SEMS is using a total different protocol?

As I believe I have a fairly new firmware I'm afraid Goodwe has changed something that breaks the support for port 8899. Any suggestions?

AFAIK, inverter is pushing data to SEMS portal, so there is no listening port there. As for the firmware, as mentioned in description, there seem to be 2 firmwares - "inverter" and "arm". It's the arm firmware which tends to be old and not exposing UDP protocol.

How can I tell which of the firmwares I have? I guess both support the UDP protocol if arm type is of recent type. Port 8899 IS open but it won anwer anything. I also noticed the base adress to be set to 247 (=F7) on the LCD screen. Looks fine too. It should work.

Do you know if SolarGo also uses the UDP protocol? I read in the app description it is only supported by Inverters without LCD screen. I got the impression that other people got it to work with the 1500 XS as well.

Yes, both PvMaster and SolarGo use UDP protocol exposed on port 8899, just different protocol format/language. So the usual rule is - the library works when SolarGo works. If I remember correctly, there's a mention in some ticket about users who asked goodwe support to upgrade their (arm) firmwares and after that it started to work.
