Huawei Solar Setup

SUN2000-5KTL-L1 LUNA2000 Smart Meter Single phase DDSU666 SDongleA-05 (this IS powered when in off grid mode)

Describe the issue

I lose data via the integration when in off grid mode - I can still see everything as normal via the portal, and directly on the device via the sun2000 app. Does anyone else have this issue? It is pretty annoying as during off grid mode I want MORE info on the system so I can stay online longer - really hope this isn't a limitation at Huawei's end though I am guessing it might be... although it seems modbus comms might still be happening according to logs?

Cheers,

Cam

I don't see an error appearing in the logs, so I don't have anything actionable to work with.

A related issue is #108 . Do you see similar behavior? How do you connect to the inverter? Via the SDongleA?

CamHaug commented 1 year ago

Yeah - sounds like that exact behavior

Left it running debug logs today (power is still out) look like there are some errors there now

Also, yes - connected via Sdongle however the behavior was the same when I was connecting via the internal wireless on the inverter, I got the dongle in the hope it would solve the issue :(

wlcrs commented 1 year ago

Thanks for the additional logs. It shows a different behavior than the previous issue. Your inverter is responding with an invalid response when querying the battery type: It receives value 344 while only 0, 1 or 2 are valid answers:

image

The setup of the integration subsequently fails and the connection is closed (not necessarily by the inverter).

As I don't have a backup box myself, it is not possible for me to debug this issue myself. I encourage you (and other backup box owners) to experiment with the underlying library and raise a PR when you're able to get everything going.

You could also try to use a serial connection via the RS485 pins, but I can't give you any assurances that this would work any better...

CamHaug commented 1 year ago

I can't even find that register (47000) in the doco I have for the version I am running? Could you please link to your document?

CamHaug commented 1 year ago

Also - Interestingly 344 is the model ID of my inverter image probably not a coincidence....

CamHaug commented 1 year ago

Never mind - I found it - Poor formatting in my document image

CamHaug commented 1 year ago

Another point worth mentioning: The integration read 47000 several times DURING the power outage with no issues it then failed after that with 344...

Ok, thank you for checking that. So this confirms that the connection via the SDongleA is also forcibly closed during off-grid mode. Register 47000 is normally only read if the integration needs to re-connect to the inverter. In normal conditions the connection stays open and that register is not repeatedly read.

When I revisit the connection initiation logic, I'll try to catch unexpected responses and do a retry instead of failing completely. However, this will not result in a stable off-grid connection I'm afraid.

There is a thread on the Huawei forums about this - single admin response does not look good so far: 'in the case of power failure modbus stops running' I hope that is a miscommunication.

As there is nothing left for me to do in this issue, I'm closing it.

Just as a follow up - I tried this direct to the inverter with rs485 - the behavior on backup power is identical.
