Growatt SPF 3000

[macfloripa]

Hello,
First of all, thanks for your efforts with this project. I have just purchased and installed a SPF 3000 model and need some assistance.

I'm running the 2.6.1 version, as per your instructions. Standalone, proxy (not docker) on a raspberry pi, together with influx.

I've specified inverter=spf in the ini file, and am getting some good and bad values from the program.

---

EDIT

I just realized that I Do have an SPF, not SPH Model, so the data I posted here before does not apply to my problem.

I am having problems with a few of the fields using the spf record layout.

Specifically, the epvtoday is always Zero.

There are probably more fields that are not correct, but I've just noticed this one.

I've attached my grott messages and an excel from the server.growatt.com site.

grott.output.txt
DBG0A4103M storage data - 2021-08-29_2021-08-29.xls

Any suggestions?

Thanks

ok. Some additional information. I upgraded my shinewifi firmware version from 1.7.66 to 3.0.0.2 and now grott is not able to read the data from the unit. Seems like a new format?

T060150SPF is a standard buffered record. Should not give a problem but I see thee is a bug in the coding for this record.
I Will repair it.

Do you run Grott natively or in a docker container?

[macfloripa]

Hi Johan,
I run it Native on a raspberry pi.
Thanks.

[johanmeijer]

@macfloripa, I have made a change to 2.6 branch (2.6.1a). Hopefully it works now!

[macfloripa]

Nice. I'm getting data again, and at a first quick glance, it looks good. I'll keep an eye on it for a time and see if I notice any issues. Thanks so much!

[macfloripa]

All seems good. Question, does your docker image contain the changes you made? I want to move to a docker installation on my NAS (QNap). Thanks

[johanmeijer]

No I have not created a new docker image yet. Will do it the comming days,

[johanmeijer]

@macfloripa I created a new docker image. You can refer to it by ledidobe/grott:beta or ledidobe/grott:2.6.1c.

Please let me know if it works.

[gabrielpc1190]

I can confirm for SPF 3000 TL-LVM 24 volts the image ledidobe/grott:2.6.1c works really good!
Would be great to have some examples for Home Assistant on how to use it with this inverter.
Will try to write them

[gabrielpc1190]

I have the examples for Home Assistant already.
