    Hi Nate & Steph,
    I bought a couple of your wiring diagrams last week as a bit of inspiration in to the development of a system for my own van, Including the 12V branch circuit one
    I have to compliment you on the quality of the diagrams, which can only truly be appreciated when you have the ability to zoom right in to get ALL the detail, even down to the heat shrink on each terminal. Also the pre-calculated wire gauge/length calculations make it really easy on this pack.
    Being in Australia, I do have to change the inverter for a 240V Multiplus II, but that’s the easy part. I only wish that it was a simple as it would be ordering kits off of you guys over here. In my area I am finding that not many of our auto elec’s are familiar with Victron, most are promoting Redarc or Enerdrive, both good systems, but they just don’t seem to have the edge compared to Victron IMHO.
    Thanks for your work, it’s really appreciated.
    If you’re ever after a point of contact in Australia, feel free to reach out.
