[Bug]: Sofar - HYD 5KTL-3PH - Only 82 entities created missing e.g. Battery info and PV power

[vacuum007]

Describe the bug

Hi,

the connection works in principle and I get updated values on some entities like "Active Power Output Total", but it seems a lot of entities are missing. Especially all battery related data like the SOC.

Help is very much appreciated. Thanks for the great work in any case!

Cheers vacuum007

Same for me but i just got 14 entities, all the others got unavailable. Changed back to 2024.05.7 since this version still works perfect

[Zwer2k]

The serial number of your inverter starts with SH1051, this is the reason for missing entities. In the plugin_sofar.py, SH1... is not stored as a hybrid inverter. According to the Sofar documentation, devices with a serial number starting with SH1 are not hybrid inverters. For HYD, the serial number should start with SP1 or SP2. @ehrenhauser can you please give the first letters of your HYD. Is it also an HYD 5KTL-3ph?

[ehrenhauser]

Hello Zwer2k, thank you very much for your reply. my inverter serial is SP1ES115NBD096 and I have a HYD 15KTL-3PH. Honestly i'm not sure wether i'm doing the updating correct. I just install the update (2024.09.1) and then restart ha as recommended. After that some battery related entities are unavailable and in the integrations i realize a 2nd device with this unavailable entities. deleting the integrations an trying to set up a new one does not work but i don't know wether i'm doing the set up the correct way.

[vacuum007]

Thanks, maybe they changed the serial number system in new units? According to the sticker and the Solarman data it is a 5ktl-3ph.

Please check whether the inverter prefix is ​​set in the new version. First of all, deactivate the battery reading, the function does not work with LSE-3 yet

Can you please give 2-3 more letters from the serial number (not complete). I want to see if the model can be clearly identified from the serial number in order to display it in the integration.

[vacuum007]

Sure, Serial starts with: SH1051005KE...

[Zwer2k]

OK, thank you. Unfortunately this is not entirely clear, 05 appears twice in your serial number, one of which should stand for 5kW. For HYD models >= 10kW, characters 7+8 stand for the kW, here they are different. This is not relevant to the problem, but it would still be interesting to see what the serial number looks like for others in order to be able to map it correctly. It would be nice if other Sofar inverter owners could post the first 10 characters of the serial number + the model designation of their inverters here so that the identification can be implemented as reliably as possible.

[ehrenhauser]

Thank you, my problem is solved with this recommendation. I just had to change some names of entities which my dashboard was referring to. Thanks again

Would you know what to change in my individual config file to tell the integration SH* is a hybrid inverter? Until there is a general solution.

[wills106]

I thought the SH1 was on the older register set? Must be used on both?

Change PV to HYBRID

Change PV to HYBRID

I suspect that someone has simply taken this from the Sofar documentation. The documentation may not be correct. According to the documentation SOFAR 3...6KTLM-G3. Do you know anyone who has this model?

replace with the following

elif seriesnumber.startswith("SH1"):
        invertertype = HYBRID | X3 | GEN | BAT_BTS  # HYD5...8KTL-3P
        self.inverter_model = "HYD5...8KTL-3P"```#

Option BAT_BTS in combination with option
‘Read battery modules’ in plugine settings, allows extended readout of the BTS information. However, it does not currently work with LSE-3.

This did the trick! Thank you so much :-)
