Short notice Freeze Charge & Low Load #595

Closed robyholmes closed 8 months ago

robyholmes commented 8 months ago

Describe the bug First raised on Facebook post: https://www.facebook.com/groups/615579009972782/permalink/896274541903226/ Predbat is reporting low load figures, and also choosing to freeze charge a lot, but not always planning it, it tends to choose to freeze charge just as the next slot starts.

Expected behavior I would expect the load to be a little higher, our base load is around 350 to 400w. During the day it should be a little higher with PC running etc. However I do expect the load history will be a little lower due to New Year visiting family etc.

Predbat version V7.14.25

Environment details Dell Thin Client HAOS GivEnergy 5kW Gen 3 Hybrid Inverter with 2x 9.5kWh Batteries appdaemon.log PredBat-2024-01-08-10-23

We have been changing the day pervious, mainly has we didn't understand it at first, thinking that say 7 days meant it looked at the last 7 days (So all 7 days). We tried 1,2,3 last night to try and avoid new years which wasn't a 'normal' day of course. I've also tried 1 & 7 today but although the values change, the behaviour doesn't seem to.

I have changed metric_battery_cycle from 2 (Which it seemed to be at from new? Default is shown as 0 though) to 0. That seems to have improved things but early days, so I'll report back likely end of today with the result of this change.

Update on what it's being doing this morning. Pretty much the same. Each half hour comes it freeze charges. It tends to do this a couple of minutes (I want to say 5 but might be wrong) into the new slot. As if it's re-run the plan and changed from having an idle this half hour to freeze charge.

I've had a go at a fix, please can you test it? https://github.com/springfall2008/batpred/releases/tag/v7.14.36

robyholmes commented 8 months ago

Updated, I'll report back tomorrow with how it's looking.

I can happily report Trevor that the Freeze Charge issue appears to be resolved. It's working far more like I'd expect now, using a lot more of the battery and picking the right slots.

Thank you very much for looking at this so quickly! Predbat is a very good tool.
