The big advantage of charger/inverters is that you can use them to limit draw from shore power
and supplement AC power with inverted power from the batteries, to cover short-term peaks. This really transforms electrical
life on board, if you use much AC power at all.
If you don't use much AC power and don't ever plan to, then of course you won't care so much about that.
I use a Victron charger/inverter, but won't recommend it, because although it functions superbly, I don't think it's reliable enough. You want something heavy duty, with easily replaceable boards, ultra reliable.
For a charger without inverter, you have many choices. Newmar was the traditional high end, expensive American brand. But my boat
was made with a Newmar charger which blew up at about 9 years, so I don't know. Sterling are economical and have an excellent reputation. There are many others, including Victron, which might be worth a look for charger only, which does not have the complex electronics
of a charger/inverter. The larger Victron chargers use massive magnet-based transformers rather than switch mode transformers -- supposed to be more reliable and supposed to produce cleaner power. Makes them very heavy, though!
