Hello, I have a BlueSolar Charge Controller MPPT and a MPPT control display. First- according to the display - was the battery showing normal signsof being used: Only 94% left. But then it went even after charging down to 89%. I cutted the power completely and since then it's always at 100%. While in use it switches to 99 or 98%, but goes immediatly up afterwards. The same goes for the other modes, ony the Voltage still makes sense.
I do not have a Bluetooth dongle or GX device and the synchronisation doesn't react.
Do you have an idea, what I could do?
