BMV-712 and resetting minimum low voltage

In the history of the BMV712 under battery voltage there is a register showing the Min battery voltage.

is there a way to reset that register only, as it would be handy from time to time to see how this progresses.

as currently its showing a stupid low figure and I would like to see the real daily low figure.


or a daily high and low would be nice as well as a feature request in the future.


even a reset on all those history figures under battery voltage would be nice from time to time.

for that matter a deepest discharge reset would also be nice.


thanks

Hi Paul,

The procedure to clear the history is in the manual in section 4.2.5 - Miscellaneous https://www.victronenergy.com/upload/documents/Manual-BMV-700-700H-702-712-EN-NL-FR-DE-ES-SE-PT-IT.pdf

This needs to be done on the unit itself (not via the app).


Unfortunately it isn't possible to selectively clear individual values from the history, it is all or nothing. There is a little bit more info on this previously answered question - https://community.victronenergy.com/questions/556/bmv-712-partially-clear-history-data.html


The MPPT has more memory and is able to give a much better range of data in terms of usable battery maximums and minimums. Or you could get a Venus-device and be in data heaven :)

I have ordered a new Multiplus II 48/5000 plus a venus GX so will be having data heaven soon. and another learning curve

Hey there, is there any update? Possible to reset single values now?

What happens to the data in the vrm.portal after resetting the bmv 702? Will the new values overwrite the data in the vrm.portal? Is there any way to save the data on another way from the bmv 702 before reseting? (total amp h drawn, kwh charged, kwh discharged etc.)


Thanks in advance


Marcel
