Hello Mike,
Thanks for the info, certainly very useful. I have already read your blog carefully a couple of times! Thanks! We bought the boat without an engine so we don't have to do the messy work with removing all diesel stuff, just painting the engine room.
I'm glad to hear that there is 48V solar panels and wind mills available on the market. I will check the suppliers you point at.

I only had one panel hooked up last season and it did a good job charging. This season I plan to install the second one.

I think that is the way you want to go. The Marine Air X has it's own charge controller the measures the battery bank voltage and cuts out at certain voltage. Then begins charging again when the bank drops below a preset. I have not had a problem with the Marine Air x since I installed it. Hope this helps.

I use it for the bulk charge and it can drive the boat 2.8 knots without drawing down any amps from the battery bank. I have recently noticed that my batteries may be getting out of balance so I need to address this. But, I am happy with it otherwise. Hope this info helps.

A question around this: If I want solar charge it's no problem adding four 12V panels to get leveled with the battery bank voltage. When I search for wind generators I find only 12V and 24V devices. How have others solved this? Charging a 48V battery bank with a wind generator I mean (generator? charge regulator?)?
