IOG - scheduled exports stopping

Tima441

Hello

tepid-topic

I have a scheduled export running daily:
GivEnergy
IOG
export 09:00 to 18:30
If SOC 50% (changed now to 40%) until 30%

I have not monitored tooo closely but it seems to start correctly but stops early ... I think most (every?) days

Today stopped at 15:31 and SOC around 60%

Log:
Export to grid instruction set for 09:00 - 15:31 (adjusted).

Any ideas? How/why was end time adjusted?

I've kicked off a Quick Schedule to export 120 mins as temp fix

Same issue today.
From log:
2025-04-29 08:59:14100 %32.1 kWhExport to grid instruction set for 09:00 - 15:37 (adjusted).

End time again adjusted. No idea why!

Again kicked off a Quick Scheduled export for 120 mins to help

Tima441 This happens because we calculate how long it takes and max discharge rate to dump your battery.

Some batteries aren't accurate in terms of SoC indication and this can cause issues. Also, you can simply stagger multiple conditional export slots with a 5 min gap to make sure you export as much as you want.

@MrMessy did an excellent thread on this I believe, he might be able to dig it out.

admin OK.
I have 3 x 8.2kw Gen 1 batteries = 24.6kwh
Max discharge rate is 2.6kwh with Gen1 hybrid 5kw inverter
So almost 10 hours discharge in any case

However on sunny days solar is producing around 5kwh even in April and that means the max draw from batteries is constrained. Afaik max export is about 6kwh (not sure if GivEnergy or DNO limitation).

Pic demonstrates nicely

But no big problem... I will split my schedules

I've made it far more granular now, like this...

@admin one thought would be to add a toggle button
OFF = scheduled times are fixed with no adjustment
ON = scheduled end times are adjusted by WW according to expected SOC or other factors

MrMessy thanks for that.

With my Gen 1 batteries and inverter I'm now using 3 sequenced schedules- starting 08:30 and ending 19:30 with low SOC to 30%. It leaves plenty for evening usage until cheap period. The cheap period might only fill 60% in worse case - but we seem to mostly get extended cheap periods that mean batteries are at 100% at 08:00.

In winter heating season I'll probably stop the forced exports as it's not worth the effort.
