Hello everyone.

I have a project on the go and I would like to get some advice on what would be the best options to rig up solar panels on an aluminum pontoon boat.

One of the pontoon boats I am planning to convert is 19 feet by 8 feet / 5.8 by 2.4 meters.
I plan to cover the entire boat with panels, so I can do 9 X 360 watt panels... the panels I can get are 3.3 X 6.6 feet or 1 X 2 meters.
( Being in Thailand, sunlight is almost always there and shade is a good thing!)

Anyway I figure the total watts will be around 3200 watts.

I was thinking about get several small charge controllers and using only 1 or 2 batteries as a buffer but running mainly on the power from the panels

... Lately I have been thinking about using dc to dc buck converters.
I am thinking ,, If I was to get a buck converter for each panel and connect them in parallel, I would need an automatic cut in and off switch to protect the battery right!??
My inverter is 6000 watts 12 volts pure sine wave so I want to stay with 12 volts.
I know I can run an AC motor from there which will be cheap for me to get.

If anyone out there can tell me if I am mistaking about using buck converters? And about the battery protect switch does anyone know what I could use??

It seems like sticking with just mpp solar chargers would be best to charge your battery rather than dc to dc converters.
 
While I haven't tested both, I think MPPT chargers are the most efficient setup possible right now. Also it seems a bit simpler - You can put some panels in parallel or series and reduce the cost of electronics.
