One of the first steps to getting Wally the Airstream up and running was to establish the power system.  The Victron Multiplus is the central brain for the power system.  

It has a lightning fast transfer switch to take us between shore power and our battery array, a charging circuit to keep our batteries managed appropriately, a 3000W inverter, and is all manageable from a web-based console.  This this is awesome and I'm looking forward to getting it connected to my batteries, solar, and shore power!
