I've had some issues with my automatic overnight charging recently, which seems to be down to a slight quirk with the GivEnergy inverter, rather than my control software.
As far as I can tell, it seems like if the battery has discharged to its minimum (<5%) and you have the "Discharge Power" set to 0, then it doesn't charge the battery, regardless of the charge settings, if the battery has more charge remaining or "Discharge Power" is set to a higher value, then it seems to work fine (based on my limited investigations, as the only times I've encountered this have been in the middle of the night when I've woken up and noticed the battery isn't charging, so haven't got too in depth with the testing!).
Anyone else noticed this? Any ideas why this might be the case? Doesn't seem like the correct behaviour but maybe I'm missing something.
I think the fix for my charging system is simply to keep the "Discharge Power" set to a higher value, rather than 0, as I believe if the battery is currently set to charge then it won't discharge anyway (as obviously it can't charge and discharge at the same time) so not a big deal, just seems odd, and meant I had to use a load of high rate grid energy to get through yesterday!
