Discrepancies in battery voltage between MPPT and BMV

Our MPPT often shows a different voltage reading to what the battery actually is. (13.5 vs 13.3). This means that our solar goes into absorption/float before the battery is actually full. Any ideas why? I have set up a smart network which helps but we still need to know where the error is.

There is no Smart Network symbol on the mppt screen.

Join the MPPT to the BMVs VE.Smart network.
