Here is how to update the Firmware in your Victron MultiPlus or Quattro inverter charger. This is something you would only do if you had a good reason. Examples of a good reason include a new installation, an existing installation experiencing difficulties, or if you are trying to put these units together to work in parallel, split phase or three phase. Updating the firmware is like updating the operating system in your computer, its just not something you do every day or for no reason. This requires a password which is revealed in the video.
