Battery did not charge over night

Hi, for some reason my batteries did not charge as per schedule setting. The previous night worked fine but last night the batteries just kept discharging un...

Hi again that's 2 nights in a row that schedule has failed. Broadband has been stable. I have had to manually charge with shine phone app which is working fine so inverter is connected to WiFi OK.
What can be causing this?

Hi, it worked tonight, let's hope it's fixed.

Hi again, I'm still getting issues of charge failures over night. I seem to get 1 or 2 nights where it charges and then the next night a failure and this keeps recurring. My broadband seems to be stable now and most nights I am up watching to see if everything OK.
Last night WW failed to charge again so I decided this time rather than using growatt app to start charge I would write another WW schedule and that worked perfectly.
Can you shed some light on this as I will not be able to keep staying up to check soon.
Kind regards
Ty

elliptical-visit This does seem to be purely a Growatt API error that indicates the instruction wasn't set successfully, see our logs.

I wonder if we put a separate retry in after say 5-10 mins. Looks like your 00:35 custom charge schedule did work.

Hi, it's like the growatt inverter has gone to sleep and by the time it's awake its too late so yes a seperste retry might be good.
Also I'm not sure if it's this but during the day I sometimes refresh the WW home page but I didn't do it yesterday and maybe not on the other failure days so again does this wake something up.
I would like to go back to the smart charge schedule but I found the predicted solar was way off with this very grey weather we have been having so thats why i decided to charge 100% at night for the time being.
OK, so do I need to do anything my end?

elliptical-visit The refresh of WW is not necessary and has no bearing on this.

Nothing to do at your end for now, we'll put a delayed retry in for this specific error.

elliptical-visit

Hi again,
well we had 8 successful overnight charges but tonight failed again for some reason.

elliptical-visit Looks like last night was fine?

elliptical-visit

Hi, yes but the 00:30 failed that's why I had to do another schedule.

elliptical-visit Ah yes, sorry, missed that, usual Growatt response error (for you) by the looks of things:

Wish Growatt could shed more light on what this means?

elliptical-visit

Yes it's getting annoying, is there a firmware or software update maybe that needs installing?
It's been fine for months and months and now it's decided to play up.
I'm only up cos I've had bowel surgery and still having frequent visits to the toilet so off work at the moment but hope to go back in new year, then I will need my beauty sleep! Lol

elliptical-visit Would be worth to see if Growatt knows what this error message means that comes back from their web API.

Wishing you a speedy recovery!

Hi, just to keep you in the loop, Growatt think same as you that it's an Internet disconnection issue and for me to unplug and replug the WiFi dongle which I did yesterday so we will see if that has helped in due course.
I'm not convinced but time will tell.

Hi again, it looks like the issue still persists, the 00:30 schedule failed.
I will let growatt know and see what they say this time.

Happy New Year to you all, I've been making changes to my Internet as there seemed to be some possible confliction with some old tech and new supplier. All seems good now however on 2025-01-03 00:29:02 you state failed to set inverter charger....... but it did charge!
There is nothing set on shinephone app but just thought I'd let you know.
Kind regards

GeeCee

Same problem for me last night and into this morning with GivEnergy All-in-One and Agile Octopus

Copied to another thread.

elliptical-visit

Well I thought it was soughted but ive had another 3 charge failures this week. 13th, 17th and 19th.
I have emailed growatt again but I can't see why this is happening?

admin

elliptical-visit Same issue, I'm afraid, we get an error message back from Growatt:

elliptical-visit

Hi, here we go again!
After 6 successful overnight charges its failed again on the 7th.
I have had some communication with Growatt and they say I need to contact my energy provider ( Octopus) as they control the inverter through an API platform and need to get the URL and code too see if it's a Growatt server issue.
I told Growatt it has nothing to do with Octopus as its WW that contoll my inverter. I am only on GO as Intelligent GO didn't seem to work on my system if you remember.
I have not heard back from Growatt for nearly a week now.
The only thing I have changed is my broadband provider and since then I've had these intermittent charge failures so I need to find some way of monitoring my broadband and see if it drops out particularly overnight. I will try and get them to look into this and see if they are open and honest and tell me there is a problem!
At my end I am going to just use Shinephone to control inverter for a while and see if the failures still continue.
Any suggestions would be greatly appreciated as this is getting so frustrating.

Regards
Ty

elliptical-visit Can confirm we had the same message for you as before, datalog_time_out. I'd imagine when using the ShinePhone app or Growatt dashboard you might also get some weird error message now and again, as we are effectively mimicking the same web API calls.

The datalog_time_out in all likelyhood refers to a timeout issue with the Wifi datalogger.

Let us know how you get on and what Growatt come back with.
