Sorry if this sounds too simple - don't mean to insult but . . . .
Are you sure there isn't a minus sign before the Ah reading? Any Ah's that have been taken out of the bank are recorded (obviously) and the number increments but with a -ve sign before it. When a charge source is attached the number decrements until it hits zero (again I apologise if this is all too obvious).
Mine does exactly as it should - no matter what the charge source. And over time I have gotten the settings quite right so when the Ah reading gets to zero, the RHS green LED flashes to say the bank is fully charged.
I ssume the charge source is running through the shunt? Because maybe the decrementing number is real currnet draw, not charge amps.
