Re: [Electric Boats] Charging 48V system

 

BR:
 
I have had a Thoosa 9000 system installed since 2008 that has worked very well on my 8 ton 30 foot sailboat.  If you are interested I have posts on how I installed my system starting here:
 
As for solar charging you do not need to use four 12 volt panels for charging. I purchsed two Kanaka 48 volt panels and a Morningstar 48 volt controller which simplifies things. 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.
  As for wind generators you can get the Marine Air X in a 48 volt version which is what I have. That has worked great in keeping the battery bank topped up over the winter. 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 also have a Zivan-NG1 charger which has done a good job in charging the bank via my Honda 2000 generator. 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.

Hello all,

I will go electric in our Allegro 27 sail boat in a year. When looking at the different systems available today I like the Thoosa 48V systems. 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?)?
