question

"With batterylife" really is a northern hemisphere feature, it can be unhelpful at times especially if a system is undersized and it struggles to charge.

I would disable it (don't use it in SA myself) and manually compensate limits for seasonal changes, or build/size a system suitably so it doesn't matter.

You can't change the active limit, it gets there because you are not fully charging with PV, this is documented in the manual.

The active limit will increment up and down depending on how close/far you are from fully charging on a daily basis.

June is usually the worst PV month in SA, due to weather and change of seasons. Same happens around October. We lose about a third up here, the coast is worse but that always is the case year round.

Here's a video on scheduled charging https://www.youtube.com/watch?v=eUcN5HC8ZT4

If you set a start time of 17h00 and a duration of 30 minutes with a SOC of 80% the system will block discharge for 30 minutes and if below 80% it will grid charge. Console will show a state of sched charge. If it does not show this and is charging from grid that would usually show you have discharged beneath the active minimum - the console should show ESS#1 ESS#2.

The 80% is the target for the duration of the schedule only but also happens to be your active minimum SOC for ESS so the system will always grid charge below this anyway.

I think you are confusing the SOC active limit with the scheduled charge active limit which would match what is in the schedule. The active limit will remain unchanged from what it was.

I have changed to "without batterylife"

but the scheduled charging is still not behaving correctly:

It showing that the scheduled charge is active at 20:51 because the battery is =80% by I have specified it should only do this between 17:00 - 17:30
