MPPT 100/50 Firmware bug V1.50

After upgrading firmware through Victronconnect, the Battery current display is wrong. For example 650W of solar power displayed, close to 50A actually coming out of unit but Battery Current display shows only 9A for 3 or 4 minutes, then correctly shows 49A. The Battery current display used to be correct and vary continuously with the actual current out of the unit but now just seems to be (very slowly) randomly updated. How do I revert to previous firmware whilst the bug gets fixed?

Hi @jimwsmith, thank you for reporting this. We found the same: on smart solar chargers with VE.Smart networking enabled (synced charging for example) the battery current reading is very slow to update, or not update at all.


My apologies for this - we'll have it sorted within a few days.

Hi @jimwsmith, an update: last night we released VictronConnect v5.24, which fixes this issue. In case you’re on a Apple phone/tablet or laptop, it might take max a few extra days for the store to accept the version and make it available for you.


apologies again & thank you for helping to make a better product.

Thanks - that is a temporary fix, leave the Smart Network and battery current is real-time again.

Confirm that Victron Connect V5.24 does fix the issue for me.
