 There is no limitation on the type of system: single unit systems, parallel, split-phase, three-phase and also large systems of 6, 9 and more inverters can all be updated remotely using this feature.
+It is not required to keep your Victron equipment updated to the latest firmware version. Stable systems should be left with their current firmware. Firmware updates should only be done when it is recommended to fix an issue you are experiencing, or add a new feature that is required by the installation.

 ==== 2.2 Disconnect VE.Bus BMS and/or Digital Multi Control ====
 It is not possible to update a VE.Bus inverter, or inverter/charger in case there is also a VE.Bus BMS or Digital Multi Control (DMC) connected to the VE.Bus network.
+This exception does not apply to a MultiPlus or Quattro with VE.Bus BMS V2. In such systems, a remote firmware update of the VE.Bus inverter or inverter/charger is possible.
 Error 734, “Cannot update with DMC or VE.Bus BMS connected” will be shown during the process when attempting to update such system. No settings or firmware is altered at the time, the system will remain operational.

+In case you're wondering how this can work without internet: thats because first the current configuration is retrieve from the system, then the new firmware file is being uploaded to the system. And only once thats done and checked for file integrity, the actual firmware update starts.
