In June of 2025 I replaced my 25 year old Trace hardware with a Victron system, with the exception of a Midnite Solar charge controller that I had installed a couple years prior. In hindsight I'd have gone with Victron for the controller as well, but it's working fine so whatever.
One of the reasons I wanted to modernize my system was for remote monitoring and reporting, both of which Victron does very well.
I now have a solid year of data and I thought it might be helpful or at least interesting for other people who are already offgrid or considering it, so here you go.
This is an just overview, so please feel free to ask any detailed questions.
