Hi Brian, I watched hundreds of videos installing lithium battery systems in sailboats and also in RVs. I found MarineHowTo.com had a link to Victron diagrams and there are many many videos describing each Victron module on YouTube. I didn't go very deep into solar panels, which is probably where I'd start if our boat was on a mooring. My situation is different. Our boat is in a slip with 30amp power available and we enjoy air conditioning, no extra charge. I couldn't build a lithium/solar system large enough to support air conditioning so it lost a lot of attraction. We mostly daysail and return to the slip. When we cruise, my wife prefers a marina over anchoring out, where they have a pool, so we take a slip at a marina and plug in. We enjoy walking strange towns and learning the history and finding good restaurants and live music and meeting new people. It's all part of the adventure of cruising.
