Hi, Until recently my AIO has been charging correctly under the Wonder Watt Agile window/SOC settings. However, recently it has stopped charging correctly. For a couple of days (before I noticed) it was only charging up to 20% during charge slots. When I realised this, I checked it would charge correctly when activated directly through the GE app. Then I resynced the inverter time and reset it. I deleted all my Agile charge windows and set them up again. Last night, the battery did charge but now stopped at 55% SOC despite being set to charge to 100%. I have attached some screenshots from WonderWatt and GivEnergy to show the issue. Any advice would help prevent me from hitting my AIO with a hammer in frustration!

@"Andy"#p5818 What is your WattID please? Name under the version number in nav menu. And what do your Giv logs say around the 4:30 mark? Looks like something went awry with that slot.

Thanks for getting in touch so quickly. My WattID is purple-intention. [URL=https://i.imgur.com/851B7jL.png][IMG]https://i.imgur.com/851B7jLh.png[/IMG][/URL]

@"Andy"#p5820 Thanks for that, so looking at our diagnostics logs, there's nothing out of the ordinary, we sent the instruction fine and it was accepted by Giv without error messages. [URL=https://i.imgur.com/f4UUp1u.png][IMG]https://i.imgur.com/f4UUp1uh.png[/IMG][/URL] I do notice the Axle inverter settings check there for Enable AC Charge Upper limit, even though it looks like that caused an Inverter timeout. Looking at your detailed graph, it does look like the charge did start at 4:30, but then stopped shortly after. Are there any other automations you have enabled? Can you toggle the 'Filter same value responses' and 'Filter errors' to On in the Giv log please?

[URL=https://i.imgur.com/DW1ICBt.png][IMG]https://i.imgur.com/DW1ICBth.png[/IMG][/URL] The timing did indeed start at 04:30 but stopped at 55% SOC. As I mentioned in my original post, for a couple of days before now, the inverter has been responding to the charge window timings but has stopped charging at 20%. I went through and deleted any old settings and manually checked it would charge correctly but now it seems to be topping out at 55% when charging through WonderWatt. I can charge it past this if I manually set the charge window on the GivEnergy App. There are no schedules set in WonderWatt any more, just the two Agile automation that were shown in the earlier screenshot. The only automations/API keys set up for my inverter are Axel Energy for the Givenergy Giveback scheme and WonderWatt.

@"Andy"#p5822 What is your AC Charge Upper % Limit set to when you check in the Giv portal (Remote Control)? [URL=https://i.imgur.com/MVM6ftM.png][IMG]https://i.imgur.com/MVM6ftMh.png[/IMG][/URL] And is Enable AC Charge Upper % Limit on?

@"Andy"#p5824 Looks unrelated to anything at our end really. Could you ask Giv what caused this? They may have some more detailed insights.

I will do so and update you with any response from them. Thanks

@"Andy"#p5826 Thanks. What’s strange is that I cannot see us setting the AC target SOC in your log, but we have it in ours and it was accepted by Giv…

I have my charge rate set at 3kW in" Advanced " in WW as low and slow during the winter months seems a good strategy. I notice it charges at a little over 4kW. Yesterday I went into the Giv portal and checked there. It was set at 4kW so I changed it to 3kW and got a " successfully written response. I notice that overnight it has charged at 4kW so definitely something at Giv I would have thought.

Has happened to me as well. Will be interested to see Giv's comments if you can report back what they say. Thanks

Hi,

GivEnergy asked me to check if the inverter responded correctly when operated directly through their portal/app. The inverter and battery responded correctly to all commands. Therefore, they felt it was an issue with how the WonderWatt API was operating.

After this diagnosis, it seemed to me that my inverter was again responding correctly to WonderWatt instructions. However, recently, it seems to be failing to adjust the SOC request again. This is not consistent but on an occasional basis. It has left me quite frustrated as I end up checking the charge quite often to see if it is operating correctly. This defeats the point of WonderWatt automatically managing things.

Andy Recent instructions all seem fine? And state of charge on subsequent charge slots seems to increase, so has been actioned?

Andy it seems to be failing to adjust the SOC request again

Could you elaborate on this please?

Andy

admin Sometimes, during a slot when the WonderWatt SOC should be set to 55%, the battery ends up taking on 100% SOC. At other times, when SOC should be targeted for 100%, it stops charging at 55%. Thus, I over or under charge my battery, costing me either way.

admin

Andy Has this happened recently and if so when, so we could try and identify the specific logs? Thanks!

Related??
Despite having set a SOC maximum value - Use Fixed Charge on the Intelligent page = 85% and indeed, according to both WW logs and my GivEnergy logs saying those commands have been accepted and written, over the last 6 days, it has consistently not charged to 85% as requested. 5 out of 6 are = 100% SoC and one is 81%
I have created an Excel sheet with both my GivEnergy + WW log + screenshots of the GivEnergy portal for each entry

@admin would you comment on this, you will need to 'Zoom' around to see each item.
All very weird

admin

KristianS Definitely not anything we can do at our end, all we do is issue the commands, if they are correct, and received OK, it's kind of out of our hands.

KristianS

Well, I thought so too. But then I looked at the app during a session.....

And so, according to the app, the ask is to go to 100% SoC....

KristianS

So then I checked my portal.

Which is the setting WW is altering.
and yet

So, according to the portal, the ask is to charge in Slot 1 to 100% SoC on the 'AC Charge 1 Upper SOC % Limit' value - so I am sure that GivEnergy would say it is doing what it is being asked to do.
Therefore, have GivEnergy changed the API in any way to change behaviours and is WW changing the correct value here?

admin

KristianS Right, so what/who set the global AC Charge Upper limit to 85%?

It looks like that overrides a specific setting for a Timed slot.

KristianS

admin WW did... Did it not?

Global settings now:

and Slot 1 settings

admin

KristianS Ah, yeah, it's the other way around, we do set AC Charge Upper global setting.

And we do reset that at the end as well, so now I'm really confused.

Is it the other way around and has something in Giv's backend implementation changed to have the global setting be overridden by the charge upper % in the timed slot? Not even sure that's available on every Giv flavour of inverter...

KristianS

I have recently had a firmware update. Let me get the details of what I am running now on my AIO
