Hi, We just deployed release 441, see the [Release Notes](https://community.wonderwatt.com/d/96-wonder-watt-release-notes). One of the big things addressed here is the earlier cut-off in terms of end time for the export, based on a calculation of current SOC, stop SOC and the max discharge rate. Shortly before (minute or two) this new end time is due, we reset back to Eco (for Giv) and 'disable' the schedule. You will see any shortened/adjusted end time calculation shown in the activity log, identifiable by the `(adjusted)` suffix. Note that your original end time for the export window does not get updated. We use a different field in the background, to manage this. [URL=https://i.imgur.com/C1IJt2F.png][IMG]https://i.imgur.com/C1IJt2Fh.png[/IMG][/URL] Let us know if you encounter any issues.

Will be testing this and let you all know after a few days.

Working here ok first evening as well Nice !

@"admin"#p2078 Still working fine here for export. I like this. Any news about SMART export ? I'm now wondering whether you can shorten / adjust the end time calculation also for import. Should be the exact same logic + set back to ECO. I often encounter what you see below: [URL=https://i.imgur.com/oHwsHmt.png][IMG]https://i.imgur.com/oHwsHmth.png[/IMG][/URL] I often only need to put just a tiny little extra in the battery in my cheap charging slot from 2-5am. Since it is sometimes so small (few % only) your calculation lowers the charge power a lot, but even with that, the desired charge is reached much earlier than 5am (sometimes 3am). That means that whatever electricity the house needs from say 3-5am, it will now pull from the grid. Could you also fix that the same way ?

@"admin"#p2078 @"admin"#p2078 hi, I cannot get a scheduled export to work at all. I am using Agile without any solar and want to export spare battery in the evenings. Times set for every day of the week and it does not mattter what I set the SOC targets to. Any tips?

@"MicHarryman"#p2620 What is your WattID please? You can find it in the Advanced section, at the bottom.

@"JMA"#p2123 @"admin"#1 Can you comment on my original post - is this possible to fix also for import ? Below is another good example [URL=https://i.imgur.com/HYt0RcC.png][IMG]https://i.imgur.com/HYt0RcCh.png[/IMG][/URL] 2:45 am: battery charged at desired level, but house will keep pulling from grid until 5am (smart charging on) This happens more and more often as we now get more sunshine.

@"JMA"#p2639 Makes sense yeah, although this should probably be an option/toggle for import.

I have asked for this from GE as its always been illogical, but they say it works as it should but never explained why they think such. To be exporting to the grid and then importing from the grid in the same HH slot is not something I need. If you can fix this it would be a winner.

Release 441 - Scheduled Export fix

admin

Ifgow We could do yeah - though it would mean that you may risk drawing from the grid during a time when the prices are expensive, as we would only revert Eco back at the end of your export window.

Ifgow

admin last night again export stopped about 3h early and about 40% higher than stop export SOC - surely that can’t be right?

Regards,

Iain

Ifgow Your SOC was 88%, your target stop SOC specified was 15%, at a discharge rate of 3.0kW and a battery capacity of 9.5, it would take roughly 138 mins, or at 2:23.

It does look like your battery discharge rate was 1500W if I read the chart correctly?

It might make sense for us to set that to max rate, which the calculation relies on.

Ifgow

admin I’ll try that, but one battery mantra seems to to charge/discharge at around 50% to prolong the life of the battery. Could the calculation not read the set discharge. Rate and use that value?

admin

Ifgow Yep - we can do. We'll make it an option for Giv users. Much trickier to do on Growatt due to undocumented and not officially public API.

Ifgow

admin sounds good, have reset battery rates for now, and left settings to run tomorrow morning if the solar energy prospects meet the criterion.

admin

@Ifgow This has now been rolled out and is available in Release 640.

By default, for Giv users the export schedules will calculate the adjusted end time based on the currently configured discharge schedule.

If toggled off, 100% discharge rate will be used.

Ifgow

admin sounds good! Will give it a bash thanks.

I'm sorry but, having read carefully through this thread, I still don't understand why my Scheduled Discharges are stopping earlier nd at higher SOCs than set. My AIO charge and discharge is set to 6kW, as per specifications. I'm away from home with only fridges and freezers running and I want to get through 2 complete charge and discharge cycles per day to get max benefit from Agile and solar but the discharges never complete.

JRWM47 Maybe the discharges don't happen at the 6kW rate?

With your 13.5 battery and leaving some margin, for an export between 6:00 and 9:00, you would expect the battery to be empty at shortly past 8:00AM at a discharge rate of 6kW.

Clearly, if there is some DC-AC conversion going on too due to some solar generation, this likely has an impact as well.

With many more schedules now available, you could work around this by setting up a subsequent second export schedule with a SOC trigger condition, and space it 5 mins or so apart from the previous export.

JRWM47

Thanks for the reply.
I've just checked back using the GE app and, yes, over the last few days all my AIO discharges have all been limited to around 3.5kW. The question now is 'why?'.
The GE AIO is rated at 6kW for charge and discharge which is what I have told WW. It can't be due to solar generation as discharges starting at 22:00 when it's dark are also limited to 3.5kW.
I understand your suggested work-around but I'm obviously eager to export my excess stored energy as often and as rapidly as possible.
Any suggestions from WW admin or other users would be most welcome.

admin

JRWM47 It might be worth querying this over on the GivEnergy forums too.

On further investigation, I think it's a G98/G99 issue with my DNO. With GE now shipping AIOs which can discharge at more than the single-phase G98 limit of 3.68kW, I imagine this will be an increasingly common problem. I am applying for G99 and meanwhile will set my discharge period to 4.5 hours. Thanks for pointing me in the right direction.
