I installed one last winter in my power boat. Very easy install, much easier than Xantrex's Links, which I have in my Cabo Rico (Link 2000). All wiring for the Victron is on the shunt, which you locate close to the battery bank, and then there is one communication wire that runs from the shunt to the display. One criticism: the push buttons on the Victron could be a little bigger, and the display is a little small too.
