Add support for Growatt MOD series

[aupilot]

Hi Johan,

It would be really great if you can add support for MOD series [1]. This inverter is partially compatible with the "default" mode, but some important data is missing (e.g. Output power). Here is an example of MQTT output:

{"device": "SFHDCxxxxx", "time": "2023-11-23T13:10:40", "buffered": "no", "values": {"datalogserial": "KWK2Dxxxxx", "pvserial": "SFHDCKF04X", "pvstatus": 1, "pvpowerin": 7915, "pv1voltage": 2800, "pv1current": 17, "pv1watt": 4760, "pv2voltage": 1661, "pv2current": 19, "pv2watt": 3155, "pvpowerout": 0, "pvfrequentie": 0, "pvgridvoltage": 0, "pvgridcurrent": 0, "pvgridpower": 0, "pvgridvoltage2": 0, "pvgridcurrent2": 0, "pvgridpower2": 0, "pvgridvoltage3": 0, "pvgridcurrent3": 0, "pvgridpower3": 466031499, "totworktime": 917504, "pvenergytoday": 216666199, "pvenergytotal": 276238388, "epvtotal": 170, "epv1today": 1685, "epv1total": 739772, "epv2today": 103, "epv2total": 1050, "pvtemperature": 690, "pvipmtemperature": 0, "battery1soc": 0}}

Cheers, Kir

Hi Johan,

first: A great project! :-) But I have the same requirement like Kir: Inverter: MOD 7KTL3-XH 4 battery modules named: ARK 2.5H-A1 Smart meter and a ShineLan-X I tried to the setting invtype=tl3 but without success. There are a lot of values missing (all regarding battery) and others are wrong (e.g. pvfrequentie: 20.4)

How can I help to fix this?

[johanmeijer]

Can you try it with invtype=min that should work also for mod type inverters

[ruedigerO]

Unfortunately not. I'd tried already. Also invtype=tl3 does not work. With invtype=default I get some data but e.g. all battery data is missing.

-> the values for datalogserial and pvserial correct (voltage_l? and Current_l?). From my point of view the data record seems a bit small?!

BTW: I use the grottserver in docker. Makes this a difference?

Ok, the data I send before seems to be the smart meter data. I get a second data set like this and think this is the right one:

Hi Johan, does the output help? Or do you need more information?

[johanmeijer]

Can you send me the encrypted data record (with the /x data). That makes it more easy for me to test.

Be aware you use grottserver taht uses grott 2.7.8 (Beta). The invtype=min is supported from 2.8.2. I have to create a new docker image for that. Will plan that.

[ruedigerO]

After updating of the grott executables (to v Beta-2.8.x) in my grottserver container and setting invtype=min it looks much better. I'll check tomorrow if all data is available

[aupilot]

I tried the Beta-2.8.x. The "mini" mode does not seem to produce any data and the "default" mode works the same as the release 2.7.8

[ruedigerO]

I was able to correlate the following readings to the WebUI: pv1watt : The first MPPT power pv2watt" : The second MPPT power bms_batteryvolt : Battery Voltage etogridtotal : Exported to Grid (Total) edischrtoday : Discharged Today epv1today : Photovoltaic Output (epv1today + epv2today) pv1voltage : The first MPPT voltage pv2voltage : The second MPPT voltage epvtotal : Photovoltaic Output (Total) eloadtoday : Load Consumption (Today) etogridtoday : Exported to Grid (Today) eloadtotal : Load Consumption (Today) pvfrequentie : grid frequency

There is a lot more but for me the values above are enough. But I'm missing the following: Current charging power Current discharging power Consumption Import Discharged Total Discharged Today

Can you check if these attributes are contained in this data?

I don't want to hijack this issue, but I am also having problems with my MOD inverter, so thought will use this issue instead of creating a new one. I'm not getting all the data with my MOD 8000TL3-X inverter.

After reading this issue I added the invtype=min to my Docker environment. The logging says it's using the layout T065029MIN.

But the value pvpowerout for example stays empty in my MQTT output.

And the pvenergytoday seems a bit strange. I'm using the HA sensors:

    - state_topic: energy/growatt
      value_template: "{{ value_json['values']['pvenergytoday'] | float / 10 }}"
      unique_id: growatt_generated_energy_today

      unit_of_measurement: "kWh"

[johanmeijer]

The record you included is not a data record. So I can not detect what the problem is.

Have you tried it with invtype=min? That layout also seems to fit the MOD types inverters the best at this moment.

[techmantel]

@Rido Check my comment here https://github.com/johanmeijer/grott/issues/81#issuecomment-2027467918 I have the same inverter and ginvtype=tl3 worked for me!
