    I'm starting to give some thought to my power source on the house boat I am
    refitting. I am leaning towards using isolators to seperate the battery
    banks. I would like some experienced feedback on what type of isolator to
    use; diode, FET or solid state? All I know at this point is that the drop
    across the diode type can play havoc with the battery life because of the
    voltage drop never allowing a full charge (?). The other two kinds I have
    not been able to get anything except that they have a much smaller v drop
    (FET) or none (solid state). And that is from sales materials. Will using
    isolators allow me to forgo the 12Both switch and just use an in line on/off
    switch?

    May seem like a dumb question but how do I know what size of charger I will
    need or does size (amps) matter other than how quick it will charge the
    batteries. I plan on having two start and two house batteries.

    How important/neccessary is it to have a galvanic isolator on the AC side?

  2. Take a look at www.smartgauge.co.uk you will find most of the answers
    there!
    Look at the "technical" section.
    BTW IMHO a solenoid based split charge system beats a diode system.
    Again all answers above.
