@@Magutz hopefully if you turn the water on slowly enough it can "catch" it before the voltage gets too high. Might be a problem if the battery gets full though and it stops taking current 🤔
I’m thank full for your video as I have purchased the same turgo wheel and am facing all the same issues. 1) no holes in the blue casing so had to make a jig to accurately drill them myself 2) hole in centre of turgo wheel is too small and needs to be ground out more to fit the generator shaft 3) key is too long and has to be cut in half I’m wondering why it gets shipped like this when so many modifications are required to assemble
Good question and you're correct; it shouldn't take that much work especially when purchased as a kit. I'm glad the videos were of some help. Thanks for posting.
I just set up a turgo hydro with the same adjustable spear nozzle as you have, for my sister’s family in Nicaragua, with one nozzle (not even all the way open) @ 40 psi I’m getting 560W. you need a charge controller or make your battery voltage half of free spin volts, essentially what you are doing is like trying to take off with your car in high gear. Your engine has plenty of power but you’re gearing is wrong.
Excellent analogy! Yes totally agree but if you're getting 560 Watts; your sister's penstock and head height are better than mine. What are the specs (pipe size, pipe length & pressure)?
@@Magutz penstock is two 2” HDPE pipes 900 feet long with 110 feet of head or a static pressure of 48 PSI. With one nozzle all the way open it drops to around 38psi.
do you have to test how many turns it makes at no load and how many volts dc? about half the revs where you have maximum power. (do the tests with 24/36 volt batteries to learn)
@@Magutz good with 140 volts.. so the mppt point is on 70 volts: put some old 220 or 110 filament halogen bulbs to see your power limit, do you have a 230 volt electronic transformer with low voltage output? you can use it to enter a PWM or MPPT solar controller for testing
Cool video. I was just wondering if there was a self built kit or something around, then this video randomly popped up. Might have to try this one out. There’s a seller for similar already built ones here in Canada, but they want 3300 for them. Wonder if these kits can be shipped to Canada.
Yes, some of them get very pricey. I am going to continue testing and searching for the best and most economical way to approach a small hydro system. Thank you for posting.
why didn't you drill and tap on the adjustable injector, where there are the protuberances to put a pressure gauge? look at my logo: I put it in a cylinder that ends up almost close to the swivel, and glued on the stainless flange that you made so that no splashes of water enter the bearing the double plug is good for 6 litres/minute; less sprays badly and crookedly I use white grease, less polluting and better resistant to water
I want to keep the same point of reference for all the experimental nozzles. (honestly, I didn't know that those spots were for a pressure gauge). Good point on the grease, I'll get an environmentally friendly one. Thanks.
Definitely loading the wheel too much. The optimum rpm should be able half the no load speed. Your troubles are with matching the generator load to the shaft power ...this is an electrical problem. Without an MPPT, you would either have to change your battery voltage, resistance of the coils in the alternator or the magnets....all of which are terrible to do vs an MPPT.
I suspect you are loading it down too much. Highest power output should be archived at roughly half the freewheel speed. For testing you should should not use a fixed 12V battery but rather a variable resistor. You could improvise one with a bucket, water, and some stainless electrodes to lower in. Maybe a bit of KoH or NaoH for better conductivity, do not use normal salt is will produce chlorine gas. It will produce oxygen and hydrogen so better put the bucket outside. With that you can apply a variable load to the generator to reach the point of maximum power output.
If you could source it for cheap you could use a three phase variac to match the generator to the load. For continuous use a mppt controller should be best.
I never thought of using a three phase variac, good idea! I'll be buying the MidNite Classic anyways but will continue trying different approaches. Thank you.
@@Magutz Mosfets are just electronic switches, without inductors, capacitors and sophisticated control electronics they can't do much. For your application a buck converter would be suitable, by adjusting the duty cycle you could indeed match the generator and battery voltage to each other. With a constant flow and nearly constant battery voltage this might work pretty okay. Of course a real mpp tracker will adjust automatically and get even more out of it. For trying out you could use three identical transformers, like 120V/24V ones and wire them in delta on the primary to the generator and in star for the secondary to the rectifier. With that you would be able to match the generator voltage closer to the battery voltage. The variac essentially does the same thing but is continuously adjustable. Depending on your generator you might also be able to rewire the windings to give less voltage but more amps. There are many possibilities.
@@Magutz Flow is not your problem here, the pipe is sized plenty. The Problem is loading the generator with a non ideal load, it is equivalent to riding on a bike, up a steep hill in a high gear. The turbine only can give you a certain torque, the generator can push >100V at no load, maybe even more. With only a 12V battery connected and assuming peak power is at 50V(half freewheel speed) you louse about 75% of the potential power. Since power = torque * speed. For a given torque you want maximum speed for the greatest power.
This plastic housing has a fixed angle of 20 degrees and it's aimed at the center of the Turgo cups. I have two new housings with different angles that I'll be testing this month with a larger wheel. Thank you for your suggestion.
No, the water is shooting from the top down onto the cups, spraying the water downwards. It wouldn't spin too well if you sprayed the back of the cups. Thanks for posting.
I know all hydro systems are different but you seem to be losing a lot of pressure when you open your jet. I run 200m of 4" pipe with a standing pressure of 34psi I use the same adjustable jets you have x3 and lose 3psi per jet. Also not sure what charge controller your using but you need one that will work with hydro Midnite classic are great.
My penstock is totally inadequate, it's only 2" and over 3,000 feet (968m) in length. Yes, I will be getting the proper charge controller and it seems like the only one that properly handles hydro in the Midnite classic. Thanks for the information.
@@Magutz I have around 60gpm from Sep-Apr way more in heavy rain With around 83ft of head. It may be worth you looking at a bigger but shorter pipe. I know it's expensive but it will pay for itself over time. Also the good thing is if your wanted more pawer at a later date you can just keep adding more pipe as funds allow. That said I'm sure if you had a better charge controller you would find a big difference with your 2" pipe. good luck

A load on the investor would bring the voltage down from 14.27v to 13v to 12v wanting the controller charger battery. Recommend a lithium iron phosphate battery can charge 1000w at 95%.not like lead acid 1000w at 50%. 100w at 90%. Then you will see a dump load to protect the turbines coils from over heating. Good luck
Yes, I noticed that. I tried to relieve as much pressure from the nozzles as possible. I disassemble the system after the tests to keep the case from deforming.
I agree and that is great advice. But I am running multiple and temporary tests. One of the leaks comes from the main bulkhead which I had custom manufactured and has just arrived. Thanks for posting.
Neither controller specifies that they are hydro ready. Only the MidNite Classic does this. The algorithm is different for hydro over solar and wind. Is there a specific model you recommend from either of those you mentioned?

Nice to see your continued experiments! You're going to get so much more power using a MPPT. I'm curious how that cheap one will do!
I will try to keep it from blowing up, it's only rated at 50 volts.

That's not an MPPT, that's cheap PWM
You may be right but that's not what they claim. The biggest problem is the rated voltage, I'll try to keep it from going up in smoke.
Buy some tools and do it properly first time only time, every leak is a pressure reducer and therefore reduced performance, do it right first time
