- Episode 1 - I will testing the Turgo Runner and new adjustable 0.63" nozzles.
This is the ME2006 hydro kit, ME2104 Spear Nozzles with the ME1016 generator.
At the end of the video, I perform a free spin test of the PMA/PMG.

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.
@@travisroyer7113 Thanks for the specs, I'll used them as reference.
Interesting watch, thanks for sharing. BTW, putting the pipe in a bucket of hot water for five minutes makes it a lot easier to bend into position.
I've have plenty of wood to achieve your suggestion. Thanks for the tip.
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.
@@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 🤔
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)
I'm not sure how fast it will spin but I cranked it up to 2,000 RPM and it put out 140VDC.
@@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
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.
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
Your advice is appreciated, thank you.
The half turgo wheel is upside down! It looks as if you are pushing the water off the turgo up against the top of the blue plastic structure.
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.
Try skipping the edge of the blade rather than hitting it full in the centre. Like a wing in the air at correct angle for lift.
Looks like you blade is upside down.
Yes, with the prototype nozzle I was able to do what you suggested and it does give an advantage. The next test will be done with a 32 spoon Turgo following the nozzle location recommended by the manufacturer. Thanks for your advice.
@@fo5zie275 It is facing the correct way, it would barely spin if at all if it were.
@@Magutz Yep, I turned my gead aorund and could finally see it. o7
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 Wow that's a long run of pipe. just out of interest what kind of water volume do you have available ?
@@johnbeattie9561 During dry conditions at least 50 GPM.
@@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
@@johnbeattie9561 Thanks. I will trying 2 different controllers next month. How much power are you getting out of your system?
remove the fan that gains 30 watts, (if it doesn't heat too much)
I'll keep that in mind and will test both ways, 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.
You totally correct, next test are different battery voltages and MPPT controllers.
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.
This is good information, thanks. I will be using MOSFETs in the future to accomplish this.
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.
Very informative. Thank you.
Your compliment is well appreciated, thank you.

What hydraulic diameter does the Turgo swivel have?
I'm not sure what the pitch diameter is but the overall diameter is 170 mm.
the case is not very sturdy, be careful that the inlet pipes do not bend the injector out of the center of the impeller
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.
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.
Sorry 1000w too 95%
Got it, thanks.
HX CONTROLLER MPPT . in Max 250 vollt DC !! -EPEVER in Max 150 volt DC
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?
@@Magutz I've been using mppt solar epever for years without problems. it takes 15 seconds to hit the right working point: in this time the turbine runs idle and the voltage must absolutely not exceed 150 volts DC rectified and leveled with 470uF 450 volt electrolytic capacitors otherwise the 160 volt mosfets will break
I recently got the XM 250 volt 60 A controller for a customer and have had good results. a turbine is quite constant like solar, while the wind has large variations and you have to put large capacitors to accumulate energy and give the algorithm time to look for the conversion point
@@udos46 I couldn't find the XM 250 volt 60 A that you mentioned but I found the Epever Tracer 5420AN which is 1/4 of the price of a MidNite Classic.
