I have a Xantrex 50 something or other that I certainly do NOT recommend! Sure, it is a so called smart charger, that is the label they past onto it. My opinion is that is slightly better than the old constant voltage transformer battery chargers. It WILL charge 50 amperes but not for long. The charging current quickly diminishes and it takes forever to recharge batteries. Impossible if at anchor for a weekend or longer.
Now solar, that is another story! My4 each 150W panels provide between 20-25 amperes for either the complete daylight hours or until the batteries attain float voltage. Heck, last week I noticed that the circuit breaker for my 8.3 cf self defrost fridge was accidentally turned off. Been that way for about a month. Piece of cake for my solar, it kept the problem a secret!
