Just add 50 or 100ms of delay just before measuring the battery voltage P.S:i have interfaced a clock and sd card and used python to draw the graph of battery and panel voltage(its smart solar charge controller?)
100ms is very less time so this wont happen
The problem that i am facing is that whenever the mosfet q1 turns on the panel gets connected to the voltage divider circuit of the battery and then it first measures the panel voltage excluding the drop and shows full charged battery and blue led turns on and after that it measures the battery voltage and shows the battery status.Is it normal or there is some problem .Reply Please.All in all it was a great project :).
