Issue with DS3-L data reading? #94

Closed LordDarkneo closed 1 year ago

LordDarkneo commented 1 year ago

Hello, I finally managed to find some time to test the overall installation with my DS3-L with 2 solar panels connected on it.

What's strange is that I am having the correct pairing / data from the info page: image

But the production remains at 0.0.... image

Any idea on how to check / verify that everything's OK?

Thanks for your help

Are you sure that your inverter is connected to mains properly (maybe switch L and N) ? Can you verify somehow that is is not damaged due to some issue like overvoltage, wrong installation ?

in another issue someone also had trouble with the inverter and the AC value was low. turned out the company did not install the inverters correctly.

@LordDarkneo did you check this page about DS3L inverters having firmware problems? https://www.quesolar.com/apsystems-storing-ds3-en-ds3-l-oktober-november-2022/ according to the visible part of the serial number, your inverter may need a firmware update.

@frtz13 *** it... When I received mine, it was supposed to have no production issue... You're right, my SN indicates that I need to update the firmware... @joffito Inverting L and N is not possible on DS3L, has connectors are différent (you cannot plug the L on the N, that's just mecanically impossible :) )

@LordDarkneo some time ago you confirmed that this invertertype worked. What happend since then? We have the console for debug purposes. We can manually poll the inverter and observe the answer. Start reading the wiki! @swbouman had issues where the grid voltage was wrong like yours. Maybe he knows the cause, they were not right installed.

@patience4711 I have been too enthusiastic... I just plugged one solar panel (uppon the 2 I have) just to test the ESP ECU (pairing and info page). But I did not get too much into details, as the info was correct (even if the production wasn't displayed, I thought is was because of the cloudy winter day...). Anyway, the DS3L has been returned back to seller for update, I'll perform 10;DIAG and 10;pool=0 once I get it back if it's still not working

In my opinion the acv line was not connected, nor there is ac voltage on the line. Please check that first.

In my installation this caused your output.

I think the DS3-L was malfunctionning. I sent it back to the seller, and still waiting for his feedback. Anyhow, the pairing was still ok, I was able to see the DC volts and send the 10;polling=0 (and yes, the inverter was correctly connected to an AC line ;) )

The issue is (for my point of view) clearly not related to the ESP ECU, asI was able to get the information from the inverter....

Quick update (in case someone is having the same issue). the reseller finally changed my DS3-L (to a 703000547xxx serial number). After plugging one solar panelto perform some tests, everything seems to be finally OK! image That's just after pairing (what's strange is the solar panel having 0.1v when there is nothing connected to it). After few hours, here's what I have in domoticz: image So now they can be moved to their final location. Thanks for all (and I confirm the DS3-L support then 👍 )
