Hi Wim @"admin"#1, I hope that you are well, it has been a while - sorry there has been a lot going on. I have mentioned this previously but during the winter when I was using all of my AIO it wasn't a problem, but now as we move to the warmer months, my desired value is now more relevant. Unfortunately, whatever value I set this to, the AIO charges to 100% SoC rather than the desired value - in my case 85% [URL=https://imgapi.wonderwatt.com/i/us7l4lD.png][IMG]https://imgapi.wonderwatt.com/i/us7l4lDh.png[/IMG][/URL] I can see in my invertor logs, however, that WW is setting both the Enable AC Charge Upper % Limit to True and the value of AC Charge Upper % Limit to 85, so in theory, it should be all good. But every time, the AIO just blasts past this value and charges to 100%. I have also seen when it says in the logs, "Keeping battery at SOC level:88%" this is the outcome: [URL=https://imgapi.wonderwatt.com/i/J9dFsFg.png][IMG]https://imgapi.wonderwatt.com/i/J9dFsFg.png[/IMG][/URL] So, something is not quite working right with WW and GivEnergy in this regard. WW ID: zany-sound

@"KristianS"#p7265 That’s weird. Sounds like an issue at the Giv side, no? Have you been able to use the Giv app or desktop site for setting a similar schedule with target SOC and repeat the same behaviour?

If it's any help, I can test this tonight for my G2 hybrid, to see if it's a general issue or specific to AIO.

@"MrMessy"#p7270 That would be very useful to narrow it down, thank you!

@"admin"#p7271 OK, have set this. Should be done at approx 04:30 (no EV tonight). Will report back in the morning. [URL=https://imgapi.wonderwatt.com/i/blK3ZEK.png][IMG]https://imgapi.wonderwatt.com/i/blK3ZEK.png[/IMG][/URL]

@"admin"#p7268 Yes, weird indeed. To be fair, I haven't tried that recently since being on IOG, but I will have done in my early days of testing when I got the AIO

Cheers @"MrMessy"#p7273 I will be interested in your results. Fingers crossed it is not just mine.... or it could still be unique to AIO.....?

@"KristianS"#135 @"admin"#1 [URL=https://imgapi.wonderwatt.com/i/MTyTtm6.png][IMG]https://imgapi.wonderwatt.com/i/MTyTtm6h.png[/IMG][/URL] [URL=https://imgapi.wonderwatt.com/i/0mllLIn.png][IMG]https://imgapi.wonderwatt.com/i/0mllLInh.png[/IMG][/URL] Times didn't need changing, as they were already at 23:30 and 05:30. If you need to check exactly which registers were issued commands: primary-hotel

Thanks... It's good to know that your GivEnergy setup is doing as expected. Now that I don't need to charge my car this evening, I am tempted to set a manual setting via the GivEnergy app to prove that my setup will do the same, with the same expected outcome. I will disable WW IOG for tonight and set a manual for a 90% value [my AIO is currently at 88% so an 85% SoC would not charge at all].

Smart Charging - Switched to Use Fixed Charge to X % being ignored

KristianS

This is my listing of my settings.... now I have managed to query them correctly

KristianS

And I realise that this is small fry to the likes of you @admin - but I am feeling rather pleased with myself this Friday evening...
Updated via the API

admin

KristianS Very good! It’s nice to have a poke around. 🤩

So, is there an issue with your Giv AIO & fw combo not using the global register on your set up?

KristianS

Let me run some tests on each of the settings in the global registers and show you the inputs and outputs.
Interesting -
Commands:
https://api.givenergy.cloud/v1/inverter/CH####G4##/settings/17/write?value=true&context="Via Postman by Kristian"
https://api.givenergy.cloud/v1/inverter/CH####G4##/settings/77/write?value=85&context="Via Postman by Kristian"

And yet this is the current state......

So for reasons unknown. Enable AC Charge Upper % Limit is not staying as toggled to ON

https://api.givenergy.cloud/v1/inverter/CH####G4##/settings/17/read

Have I just found out why your setting is not having the desired effect on my system?

KristianS

Rerun the command:
https://api.givenergy.cloud/v1/inverter/CH####G4##/settings/17/write?value=true&context="Via Postman by Kristian"
Same outcome

admin

KristianS It does look like when you read it through the portal it returns false even though it's true.

Although when you then query it via the API it also returns false? Even though you've just set it to True?

You could be onto something here. Just condense this down for Giv into the smallest reproducible example for your AIO and FW combo and let them know the details. Looks like a bug at their end for sure.

KristianS

Final screenshot of the outcome from setting the three slots via the API and the resulting actions on my AIO

Charge / Discharge settings that were configured

What we really want is to be able to manage the SoC via the global values, but if the Enable AC Charge Upper % Limit is not staying to True, no matter what value we set AC Charge Upper % Limit to, it will be ignored and the system will continue to charge until it is full...... ignoring the value as set by WW, which is not what I wanted it to do.
Simple submission to GivE on its way shortly

KristianS

Hmmmm, I will wait until after I have performed the now-present firmware upgrade....

KristianS

Post Firmware update....
https://api.givenergy.cloud/v1/inverter/CH####G###/settings/17/read gave a value of "false"
I then ran the command:
https://api.givenergy.cloud/v1/inverter/CH####G###/settings/17/write?value=true&context="Via Postman by Kristian"
which returned a "true"
reran https://api.givenergy.cloud/v1/inverter/CH####G###/settings/17/read
and now "value": true appears sticky....

So, on the face of it, it appears that this setting was faulty on the old firmware and has been 'fixed'.
I will test this tonight using the global values in my invertor settings and report back tomorrow.

KristianS

Good News item!
As per the following images, you can see that my Global and Charge Window attributes were set as the following values in the settings....
Global Values
ID: 66; AC Charge Enable to ON
ID: 72; Battery Charge Power set to 2067 (W)
ID:17; Enable AC Charge Upper % Limit to ON
ID: 77; AC Charge Upper % Limit set to 80%
as per...

and
Charge 1 Settings
ID: 64; AC Charge 1 Start Time to 23:35
ID: 65; AC Charge 1 End Time to 05:25
ID:101; AC Charge 1 Upper SOC % Limit to 100%

And this was the resulting outcome

Result!
I am now confident that I can switch back to WW to control not only my charging, but also limiting the SoC to the value I set in the tool.
Testing tonight and over the next few days different values to confirm.

KristianS

So far so good...

KristianS Excellent, good work.

KristianS

This is a quick update on the failure to reset all charging and discharging parameters through the app 'Reset to Defaults' question to GE.

My car is going to be doing a lot of charging today so I will leave it, but I will try another reset tomorrow during the day to see if I can double-confirm that the reset doesn't work on the new firmware again
