Micro Hydro - 32 spoon Turgo on Classic 250

Episode 7 - I will test the MidNite Classic 250 (63 amp, 250 volt) with the 32 Spoon Turgo and blue 0.63" adjustable nozzles. Making a power generation comparison between charging with the charge controller and directly connected to the batteries.

Great show I'm learning a lot about hydro . I would like to set up a small hydro to charge my battery in my camper here in NZ.

Your feedback is greatly appreciated, thank you.

good video as always
I like the way of experimenting and learning.
Greetings from Cuba.

Thank you for your encouraging post.

With Lead-Acid batteries, you can have a setup without a charge controller, but if you want to use LifePO4 batteries or any kind of lithium batteries, you need a charge controller.
There will be losses in any charge controller since it's basically a boost-buck converter to converter to the optimal voltage and amperage to get the maximum possible power.

[@Magutz]

That is a great observation, I would still add some type of controller to limit your float voltage.

[@samuelgilbert9734]

If you can find a good "dump load" such as water heater, the other style of charge controller might actually make sense.

[@Magutz]

Yes totally, I will try a PWM direct connect controller once I find the Turgo/Pelton that gives me the most power. Thanks for posting.

[@Mr.Engineer.]

Do you think that you at any point will upgrade the diameter of your pentstock?

[@Magutz]

Initially I wanted 3" but it was not available during COVID, so I went with the 2". Little did I know that doing so would lower my available power from 1.3 Kilowatts to 300 watts. I think about it all the time but my line is 3,179 feet long. Yes I will but not in the near future.

@@Magutz Your videos and real world test data are great, however I think it is worth mentioning that I offer customers design analysis that matches sizing of pipeline, nozzle, turbine, and generator so that a custom H-Hydro turgo-runner will avoid the need for so much trial and error testing. There is no substitute for experienced engineering analysis. Thanks

​@@HdashHydro The 32 spoon Turgo is from H-Hydro, I also purchased the recommended nozzle. I had it calculated for 12 volts but it did best at 36 volts. You can see the test on this video. th-cam.com/video/T7-PYEp10nw/w-d-xo.html
Thank you for your feedback.

@@Magutz​​⁠ Thanks. I think the weak link in the calculation sequence is the PMA data (winding resistance and “back EMF” V/krpm). Thanks

@@HdashHydro Thank you for the update.
