Battery Discharge Power being altered unexpectedly

KristianS

Your WattID: zany-sound
GivEnergy AIO 6kW
Total Newbie, so forgive me if this is a simple one.
My Battery Discharge Power setting is being changed unexpectedly when all I want WW to do is set my charging schedule

Why is this value being altered and what does it mean if it is? I am currently not exporting at all from my system - only to the home
I found myself in a situation after a charge cycle this morning where 2kW of washing machine load was pulling from the grid at 08:00 this morning - I stopped it by resetting my discharge values to the default - 6000W.
I note this change was made when my Agile Octopus window came to an end
Will this mean I see the same outcome tomorrow?

KristianS If you want to draw from the battery in between Agile charge slots, you need to disable the 'Hold charge' toggle.

KristianS

Ah, I see. I misunderstood the use of that toggle. I thought it was for not allowing the battery to be drawn from 'during' the charge slots, but when charging was no longer possible because the battery was full. My bad!

KristianS

I am revisiting this topic again @admin because now, I have another potential challenge as I move towards managing my AIO in light of the impending arrival of an EV.
Ignoring the 'toggle hold value' part above - that is not relevant to my next query
I am still not following the reason for the alteration of the previously set 'Battery Discharge Power' during the WW cycle. I have set a value between 0W - 6000W [in my case], but why is this value being altered at the end of the cycle to same value as the 'Battery Charge Power' value, when I would prefer it to return to the value that it was set at when the cycle started - in fact, I am still failing to understand why it is being altered at all.
Thanks in advance

KristianS Good point, we’ll take a look and update you.

admin

KristianS Apologies, this definitely is a bug and has now been squashed as per Release 752.

We overlooked this when you originally reported this!

KristianS

admin Many thanks for the prompt response Sir!
That will ease my 'heavy load draining my battery' challenge considerably

admin

KristianS I do think there still could be an issue though. People that have Hold set on their Agile charge window do want this discharge power to be set back after their Agile charge window ends.

So we may need to address that separately.

KristianS

Now I just need you to enable the feature 'Turn off Eco when on "hold" for GivEnergy setups' and my last problem will disappear too.
My battery still drains at 300-400W even when on-hold - I think it must be a GE thing - but it is super annoying. The only way I can fix is to turn off Eco mode - then we pull from the grid at 100% of load.
If there were a way that by 'holding' charge, Eco could be manipulated at the same time. Then this would be utopia

admin

KristianS There is now (Release 756) a setting for Giv users in the Advanced section to allow to enable having Eco mode not active during an Agile charge window where you have Hold set to 0 Watts. We didn't want to clog up the Agile Charge window section.

Also - Delete account functionality is now available.

KristianS

I concur.
So an admin setting that states the 'level' of 'Battery Discharge Power' like we have for 'Battery Charge Power' value - in your case you call it Battery rate:

So maybe two fields. One called 'Battery Charge Rate' and another ;Battery Discharge Rate' so they are distinct from Export rates - because remember, I misunderstood and mixed the two up when I first got onboard in the early days....

KristianS

admin
Tonight is a test then.
I have set the Advanced Setting "Eco off hold" to ON - Set Eco off during 0W Hold
I have set my 'Hold' schedule to be 00:00 > 07:00 with 5 x 30 min charge slots - usually enough to mostly fill my AIO
Hold Charge is set to ON
Max Discharge = 0% - 0 watts
and I will report back whether Eco mode is turned off as expected, the battery does not discharge and the charge slots complete and then Eco mode is re-enabled at the end of the window...
Wish me luck

admin

KristianS Thanks, looking forward to your feedback!

KristianS

Good morning @admin
So, so close. But not 100%

Before session start:
Eco Mode = ON
Battery Discharge Power = 958 w
Upon session start ~ 00:00
Eco Mode set to OFF
Battery Discharge Power = 0w [you call this Max Discharge for reference to anyone following along]
Timed slots are set as per WW auto-selection

AIO and house load successfully executed as expected

Session End ~ 07:00
Eco Mode set to ON
However, Battery Discharge Power = 3994w which was not the starting value and would mean that if I still had load that was in excess of ~ 1kW - say my EV - then my battery would start to drain quickly.

I would prefer that WW set the Battery Discharge Power = # to the value at the start of the session # no matter what value that is.

Do you concur?

admin

KristianS Excellent, thanks for that, so main point being, no draw from battery, right?

The discharge mode mechanism hasn’t been changed for this functionality yet.

Agreed that this needs to be reset back to what it was before. We’ll get the snapshotting of values in place for this.

Will let you know when available.

KristianS

admin
Yes, correct

The battery draw went to zero as expected at midnight [ish, always ish by design] and didn't come back on until 07:00 ish
Understood.
I am happy for either a snapshot of the current setting to be taken, and returned - or a second field in the advanced settings under Battery Rate for a separate 'discharge' rate value to be set - if it makes it simpler to implement / manage
Great work though

KristianS

Spotted a slight misnomer today - I haven't noticed this previously... @admin

The 00:00 slot is showing as 'on - hold' and yet does not fall into the configured window....

Is that just a UI challenge, or will my invertor be set to 0 and ECO to off during that 30 minutes slot?

admin

KristianS Interesting, we'll take a look, thanks. Definitely a UI-only glitch, and likely has been there for a while. Hold works off your TimeFrom/TimeTo settings for your agile charge window.

KristianS

admin That has been my previous experience and so was surprised to see it there. Thanks

admin

KristianS Fixed as per Release 764.
