Thanks Robert,
I will put a delay ( 1 sec or more ) when changing status.
Need to wait for next cloudy days to check if OK .
Do you see any other area om the program that could be improved ?

Honestly I have trouble concentrating so it's kinda easy for me to lose track of logic.

I try to help with the simple things.

Edit: your program is huge, have you considered breaking it down?

I'd make a copy, reduce all the subroutines to only display a status on LCD, then add logic one section at a time.

Robert,
I am attaching the schematics digram for the charger and two captures.
I am sorry : it is hand drawn. I am not an electronics expert nor a software man !
This morning I have activated the delay as suggested, I am waiting to see the results in the next days.
The whole device works well and the MPPT is tracked well too.
Thanks for all.
regards,
Ambrogio

Wow!

Wish I could contribute something.

Now you're making me think of adding a solar panel to my alarm project.

I'd put it here temporarily:

   IF MODE=3 THEN
      LCDOUT INS, CLR
      LCDOUT INS, LINE1, " DC STEP TEST " 
   ENDIF

   PAUSE 1000     ' Test if problem is debounce issue

   ' Not necessary during test ... WHILE PB_1=0: WEND

ENDIF
