Solar generation in rain/cloudy conditions

13 for me so far. Definitely topping up from grid later as grid here has been dicey lately and not sitting in the dark tonight.
 
Only managed to generate 16.5kw today
Battery at 77% so will last until tmr where hopefully it can fill up
 
15.2kWh my side. Made it to 82 SOC from 60.
 
Quick one here without starting a whole thread - why would I be seeing this for SOC when my battery is discharging overnight?

I think this is the second day I've noticed this. Normal behaviour is a simple decrease in SOC over time during discharge (makes sense). I don't think it's something like a rounding error because some of those large jumps are +2-3%.

Software bug?

Meh, it is my own app so possibly. 🤣

But it's weird. Crept in out of nowhere after being in testing for ages.

Native sunsynk app doesn't display graphs as granularly as here (5 mins vs. 1 min) so the jumps would not necessarily be visible and are not visible for the relevant period.

And today it's completely normal again. /shrug

SOC values are derived from API as plain integers and are not modified in any way so I'm wondering if there's something more to this - as in BMS reporting whacky values at times.
