My Victron 700 is suddenly not displaying the voltage, only wattage, aH and amps when I hit the +or-keys. Although my App gives the correct voltage
Have a look at the manual !
Search for "52. Main voltage display" -> you can choose which settings to display or even not to display. Sounds like you accidently disabled voltage.
