Since an update two months ago, from an MPPT 75/15 to 100/50, the IP65 and MPPT started to show different states for the battery while connected at the same time. Before that, it always showed the same state.
Can someone explain if this is correct, or if there is something faulty with the setup? (I haven't done the setup).
The status of a charger/MPPT depends on the parameters set in the corresponding device.
You will probably have set different values, e.g. as the absorption voltage, so that one device is already entering the float phase while the other is still trying to reach its absorption voltage.
Absorption voltage is of course only an example, it can also be any other parameter.
Since you recently changed the MPPT I would look for other parameters there.
