[Bug]: 'Growatt' - 'Inverter Mode TL3-Sl' Modbus Error: [Input/Output] ERROR: No response received after 6 retries #1067

Is this a PV only Inverter or Hybrid? If it's PV only or Hybrid with a discharged battery, I am guessing the Inverter had shut it's self down as the time was 21:55 according to your logs. The Integration requires the Inverter to be powered via PV for the initial connection to the Inverter. |
|
this is PV only, no batteries. good point with inverter being shut but i was testing it whole day, this is now: 2024-09-23 15:15:27.245 WARNING (SyncWorker_0) [homeassistant.loader] We found a custom integration hacs which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant |
|
Released 2024.09.5 adding in your Inverter. It may still not work as I don't know what register set this Inverter uses. So may need further work. |
|
upgraded my Growatt to latest version (8914) and logs looks different: Traceback (most recent call last): |
|
It's setup to use plugin_solax by default |
if you mean the setting on the first page, yes, i set growatt each time. with 2024.09.5 initialization takes forever 2024-09-23 16:52:22.532 WARNING (SyncWorker_0) [homeassistant.loader] We found a custom integration hacs which has not been tested by Home Assistant.

|
Maybe a stupid question.. Have you restarted HA after updating to 2024.09.5? |
many times |
|
I made a configuration again and collected pcap trace with debug message taken same time. It seems converter and HA are talking on modbus level. IP of converter is 192.168.0.9 and ha 192.168.0.220. Please unzip and open with wireshark to see what growatt is replying to ha. modbus-tcp.zip |
|
If you replace Does it start working? |
|
wow, bingo! :-) it shows me 1 device and 43 entities just after changing this parameter and reboot. Thanks a lot btw, my inverter is 10kW so in the description of this line maybe the range should be 10-22: # PV TL3-SL 15-22kW #1067 ? |
|
Ok, I didn't realise I only had a quick look for a datasheet and noticed it mentioned 15-22kW. I'm guessing the datasheet I found was out of date. |
|
For some reason no parameter values are coming back from inverter, like sensor data or diagnostics: same as general parameters: |
|
Unfortunately your Inverter isn't listed in the Modbus docs. So it's a bit of guess work to see what works best. You could try changing Other option is for you to reach out to Growatt and see if there are any specific docs for your Inverter. |
|
I played with GEN2 and GEN3. This parameter causes new entities to appear in sensors section but the values are same unknown. If you would consider adding decoding schema for this Growatt inverter im sharing with you the doc which contains its modbus data format. Thanks for great support. |
|
Ok that looks different enough from the Current GEN-GEN3 and SPF Registers. |
Describe the bug
Hello,
Im using 2024.09.4 and trying to configure it with my growatt (via waveshare eth converter) for the first time. Initialization phase last forever, after configuring again with same settings im getting success box, but device is not added.
