Using a constant water stream I can produce over 15volts continually. I have gear that runs between 60-75volts. I have a 72-volt Marine Battery Bank. How can I best connect this generator to charge the 72-v bank? Thank you in advance.

Tell us if the generator is AC or DC...
And is cost a concern?

I can't believe I left that out. Thank you, it's DC.
