I am considering putting solar on my boat.
I would like to use a 48 volt propulsion bank.
As I see it I have a few options.
1 - build an array with 4 12 v panels in series and find a 48 volt charge controller
2 - take each panel and connect it to a 12V charge controller that is then connected to each battery.
3 - connect 4 panels in parallel to one charge controller and build a circuit that cycles from battery to battery.( possible detects lowest voltage battery and charges it first - hopefully keep batteries balanced)
Has anyone built a 48 volt panel array?
If so which option did you use, or is there a better way.
When I search the net everything seems geared to 12v or 24v not 48.
Thanks for any info
Mark
