Flat batteries / batteries not charging

exggman

Hi all, new to the forum and wondered if anyone knew how to solve the above?

I have a Growatt 6kw inverter
6 x Growatt 3.3kw batteries (connected in parallel)
16 x Solar panels (400 watts each)

The above was installed appropriately 2 years ago. However, batteries discharged and will not recharge?

I think it may be a communication error?

Please help🙏

Sure it will just be a setting in Shinphone App,
Dm Me i dont mind going through setting with a fellow Growatter.

PANface Hi, I am new to this group/ app and solar/ PV.

I have a growatt batteries - 4 x 5kw ALP batteries
Growatt SPH 6000 BL-UP inverter
6 x Aiko neostar 460W and 9 x Eurena 500W panels.
Intelligent Octopus Go.

All was working beautifully but the battery stopped charging overnight (battery first) a few days ago, but will happy charge on a sunny day. I still have the Shine app and this new Wonder watt connected to the system.

I'd appreciate some help troubleshooting, as the installer has not been able to help much.

Thanks in advance.

SuprDoc What is your WattID pls? You can find it under the version number in the nav menu bar.

SuprDoc

admin thanks for the reply - my ID is selfish-table

Thanks.

SuprDoc Thanks for that, I see, you only signed up today, but I can see the IOG slot for tonight already being scheduled by WW, so let's see what happens tonight, and we'll take it from there if there are any issues.

SuprDoc

ok thanks.

update - the day didn't seem to start very well, but I was surprised that there was enough solar to fully charge the battery, although wife and kids are doing their best to drain the battery this evening!

question - how can I ensure that there are no conflicts with any settings in SHINE app?
I also have a zappi fitted
Eddi and a harvi are being fitted tomorrow

What are possible conflicts if any with regards to 'smart schedules' - it seems odd that even with my low rate charge window and IOG (plug in EV during the day) - IOG schedules odd slots literally minutes apart for some weird reason? And ofcourse my phone then pings with these alerts too!
What's happening there?

SuprDoc IOG schedules odd slots literally minutes apart for some weird reason? And ofcourse my phone then pings with these alerts too

Thats basically Octopus issuing new IOG slots. They change their minds very often! Which results in updates to your IOG schedules.

SuprDoc question - how can I ensure that there are no conflicts with any settings in SHINE app?

Simply by not managing slots in ShineApp but let WW do the work, otherwise you will end up with schedules that can't be actioned due to overlapped times.

Thanks - have also asked similar in another thread but will continue on here.
So another night of batteries not charging, but yesterday - perfectly charged from solar and also I think the installers tweaked something to test pulling from the grid.

So I think there a problem with my SHINE app and I wonder if there's a 'reset to default' option on the SHINE app?
I've only got a schedule to charge my battery every night 23:30-5:30 in WW.

I've got Intelligent Octopus Go 12M fixed (as I've got EV) and Outgoing Octopus

Thanks in advance.

SuprDoc So another night of batteries not charging,

Please find attached our logs. We sent the instruction and it was received successfully by Growatt.

This means that setting it through the ShinePhone app or Growatt portal is basically not working for some reason. It probably makes sense to ask Growatt at this stage.

I'm not sure of a 'reset to default' on the ShinePhone app.

Thanks for that and is reassuring.
The only setting I can see on SHINE and mirrored in webApp for Growatt is

Battery First:
Charge Power Rate - 100
Charge Stopped Soc - 100
Ac Charge - enable
Time 1 - 23:30 - 05:30 - Enable

The installer's coming to check it out today. Will update with any other info I get.

Thanks again.

admin

SuprDoc Yep that looks like that setting should work.

SuprDoc

admin unfortunately, it doesn't seem to be working.
Will try and get SHINE totally reset and then just use WW going forward.

Update on the issue: everything was working fine for Growatt inverter and battery - with battery top-up/ charge overnight. The SHINE app setting was just for overnight battery first - on IOG with EV and outgoing Octopus tariff.
Then suddenly, for the last week, battery stopped charging overnight, after I disabled battery first overnight due to the recent weather.

Now - the setting on SHINE app don't seem to work.
This is how I ended up finding WW due to massive amounts of Googling.

In the day, the battery will charge well without any issues.
Battery discharges without any issues.
WW admin has traced calls to the inverter via WW and there don't seem to be any error messages.
The dongle is wifi.
We have switched inverter on and off.
Have logged out of SHINE - logged back in.
logged out of growatt web account.
removed schedules on WW.
in case there are any conflicts.

Running out of ideas and trying to contact Growatt.
Appreciate any thoughts and ideas on diagnostic gaps left.
I wonder if it's the wifi dongle, and perhaps change to a hardwire dongle (have got good access to this.

Thanks in advance!

SuprDoc

Just wanted to update folks in case it may be of help to people in future!

Installers came to check it out and as above could not find any issues.
They contacted Growatt directly and were told that they could see an issue on the server side where it looked like a command was received, but it was not transmitted to the inverter.
In any case - this was fixed and now all working.

I am worried though in case this happens in the future, and I didn't really get an adequate explanation of why it happened in the first place.
It seems such a shame that there is no manual overide?

SuprDoc Thanks for reporting back, glad you got it working!
