Here's a story for you!
I thought the my major problem was going to be getting the CREEK (14000gpm) to turn my wheel fast enough to produce power. Wrong answer.
Wheel turns from 6RPM to 12RPM depending on what my Midnite Classic 250 has as a MPPT.
I have a gear ratio of 35 - 1 so, if my wheel is turning at 10 RPM, my PMA is spinning at 350RPM. Peak RPM is 380 for 120vac, rectified I get 227VDC out of my rectifier into the  Midnite Classic 250.
Problem is, very low current.
I'm charging 14kwh battery bank of Nisson Leaf Li-ion batteries that have a 30a optimal charge current and I am getting 1 - 2amps in! 1 can pull 1500wstts for 8.25 hours out of my batteries, but then at 1 -2amps in, it takes 5days to bring the batteries up to the 58.8vdc full charge!
This is the 3rd PMG, 2 MPPT charge controller,  3rd set of batteries L16S, Deep Cycle lead acid 12vdc in series parallel (2banks) for 48vdc(58.8vdc) new 14kwh Li-ion batteries.
I AM AT A TOTAL LOSS, AM I AM AN ELECTRONICS INSTRUCTOR AND TECHNICIAN WITH 30+ YEARS OF EXPERIENCE!
Midnite Classic has said they think their unit is working properly, so don't bother calling back.
I won't let this thing beat me, but right now I need some help!
