Wake op on charge stops working on solar panel

[Xorx29]

Hello there! Im using pijuice powered by solar panels from pijuice, im managing the battery by setting thresholds with pijuice_cli to power off on 40% with the function SYS_FUNC_HALT_POW_OFF and 50% of battery to turn it on.
At first it works during 4/5 days, but then one day turns off and never wakes up again unless I turn on manually and then starts againg working fine.
When I turn on manually its at 99% of battery, it's been off for 3 days, even if it has more than 50% it never turns on again and this has been happening to me, sometimes varying the time it lasts correctly.

Is there any possibility that the wake up will be deconfigured by itself?
After it happened to me more times I started to keep it under observation and this last time when it turned off it was during a cloudy day and the powerinput was WEAK, from then on it did not turn on again.

I've read on a issue that if its turn off when HAT is getting power it could deconfigure, could be that?
