WOJACK: Since your project is for a portable microhydro, it is best for you, that your generator produces high AC voltage for easy power transport with flexible low gauge wiring and at the load a transformer or transformers to the charge controller level equal to the PV panel output, this way a single controller will suffice.
Forget the idea of the battery bank by the stream --not needed -- with high AC voltage the scheme will be simple and low weight, as well. This is the scheme I developed for a friend that have been roaming USA for the last 7 years, he is supposed to contact me at the end of the year when he comes down from Alaska. He got a 6 or 8 inches flexible foldable pipe to bring the water to the low head generator ( he has two turbines; one Banki and one propeller to use depending on the water source ). 50 up to 200 watts, if I remember right, 3 phase 120/240 AC volts converted to 24 volts battery charging. I do not remember where he got or how he got his collapsible pipe ( up to 100 feet) , it looks like a firefighter hose but not as thick, it is thin and capable of 80 PSI, good for the sites heads he was planning to use.
