Victron has released VictronConnect for your laptop. Similar look to your iPhone App for updating MPPT’s and BMV’s but this is for programming Multis and Quattros for most of the function VE Configure for basic single-phase systems.
It’s now very easy to update the firmware on your Multi with VictronConnect with one button click. Password: zzz (three z) Go to the three dots top RHS, Product Info / Firmware / Update and click UPDATE. It’s as easy as that.
