    What are the thoughts on adding solar to a 46 convertable? Not for full operation just to run the fridg, tv, and a couple lights over night while on an anchor or mooring?

    How do you expect solar to work at night.

    I would start by simply building a battery bank that would run the inverter large enough to handle those items. Lithium batteries are quite small for the amount of AH they hold. It could then be charged during the day by the engines, or generator or a battery charger while on shore power.

    No need for a power selector switch. Charger/Inverters are usually in line now days. This way the fridge keeps running automatically if you loose dock power.
    Just maybe a by-pass switch if your concerned with inverter failure/service.

    During daily operation, you will get higher re-charge rates from a gen-set or engine alternator than a solar panel.

    For extended anchoring out with out a fridge (or other heavy loads) running, solar charging is great for bilge pumps and alarms.
