How to find voltage data of my battery bank over the past 12 hours as monitored by cerbo/quattro on the victron connect app?
If you’re logging to the VRM, you can go to the “advanced view” and add the Quattro’s DC stuff (VE.Bus System, VE.Bus DC Voltage and Current). If you have a battery monitor of some kind, add DC voltage & current for that instead. Both of these options rely on the VRM to provide historical information.
If you have Victron MPPT, they keep some history independent of the VRM that you can view locally.
It will depend on what you actually have that is monitoring the voltage.
Some devices can do trends.
The quattro cannot do trends, so the only other two options when using the cerbo is local storage on and sd card or the vrm as mentioned.
