One thing I noticed is that a 440 foot pipe with 5” ID on a 24 foot head is not big enough to deliver the amount of water required for 850 Watts. At 316 gpm you will lose 7 feet of head due to friction losses. So 316 times 17 feet (dynamic) head, times gravity, times turbine efficiency - say 55% at best - would give you a maximum output of about 640 Watts. Low head systems are always very sensitive to losses so all in all I think you did well to get 495 Watts. Great video.

At 18 minutes, when you are reading the output, that is a MPT control unit, so if the batteries are charged, then the controller will reduce the power being put into the batteries. To correctly test the system, you need to test it as a stand-alone generator on flat batteries. Or if you can prevent over running and the high voltage that goes with it, try an open circuit test.

Maybe checking the bearings on the generator would be a good idea. The waterwheel didn't seem like it was spinning freely when you moved it by hand. Also, the water output/exhaust at the end might not be exiting freely causing flow problems in the waterwheel chamber. I remember someone creating a Venturi effect with some simple piping after the generator to increase throughput. Just a thought. Cheers!

Have seen that venturi effect its interesting.

Over in Idaho in the Frank Church Wilderness Area on the Middle Fork of the Salmon River, we have a pelton wheel with a max out put of 45kw. We have a 1120ft head starting at 12" shallow wall PVC when decreases to 10" then goes into a thick wall 8", down to a six. From 4" diameter and smaller the pipe is metal 20ft from the powerhouse, it drops to 4" metal, 10ft later it drops to 3". At the pipe enters the power house it decreases to 2", 2ft from the turbine it drops to 1" then the two nozzles are 1/2"-3/4" depending upon time of year and water volume. At the turbine we have a static pressure of 260psi with a water volume of 250-300 gallons per minute with a maxium out put of 45kw with a governed turbine speed of 1800rpm with a pelton diameter of 28". One thing over looked by many is the transition point from m one diameter to the next. With metal, it's easier to shape a cone, permitting a smooth transition to each smaller size where a lot of people just drop from one size to the next, creating a lot of turbulence at each size reduction. Reducing your gpm because of friction in the pipe at each reduction.

On both systems you need to build a "pond" at least 3 feet deep....with the excess flow able to pour over the dam wall and flow on downstream. Use an intake pipe twice the size of your penstock as the receiver of the water in that pond. The double size pipe (capped on the upstream end) needs to have very many small holes drilled in it...say 1/4 inch holes all over it.....then wrap fabric shade cloth or fabric wind break cloth around the pipe as a filter... Now suspend the drilled wrapped receptor pipe half way between the floor of the pond and the top of the water...the cleanest water zone as the silt drops to the bottom of the pond and the leaves etc. float over the top of the dam..... The small holes do not allow a vortex to occur...the number of small holes allow full flow of "solid" unaerated water to fill the penstock. Now you have also eliminated those small stones, leaves, sticks.... and the bubbles.... See Marty T channel (he is in New Zealand) for a washing machine motor based turbine putting out 885 watts continuous from a 229ft head 4 inch penstock....going 18 years on the original system.....

I've even met some who didn't know how three and four way light switches worked, but they could hook em up and get em working. But it was regimented, no understanding involved, just repeat the procedure. And known lots of electrical engineers who lacked capability to fix electrical things. (Often the most advanced in theory had the most difficulty in practice.) It all depends on people's specific interests and level of dedication. At ten I was fixing appliances, TVs, stereos, small engines, etc. It's amazing how reading library books and getting hands on things can lead to understanding.

For every 90 degree bend in the headstock piping you loose approx 15% flow rate. For every 45 degree you loose 8%. The generator has a 90 degree turn built right into it making it inefficient for that volume and flow rate of that creek! Those look like globe valves and they probably reduce flow by 10% each. They should probably be gate valves and I think you could probably eliminate the one near the generator all together! First thing I would do is straighten every pipe I could eliminating all the offset fittings. Then I would build a small dam creating a 5 foot wide head pond with a large inlet funnel down deep so as to eliminate bubbles and screened to eliminate debris. I would add another 5 inch pipe running alongside the existing one with a larger diameter wye pipe with a reducer at the generator. I would try to increase the length of the pipe as much as I could. All that would increase the pressure/flow rate to the generator. That is what you can try using the existing equipment. But the truth be told I would get another generator/turbine. That generator is too small for that volume/ flow rate. Or you could replace the piping with a smaller diameter one, say 2 or 3 inch. That would increase the flow rate greatly if you had a head pond with a larger collector/ funnel. But honestly I think the turbine is too small for that application and that is what I would either replace or modify. Try cutting a larger hole on the turbine for the water to be exhausted with no restrictions/diversions. The turbine is just poorly built. Get rid of any restriction after the water spins the blades. You don’t care if it sprays out in a large fan shape!! I would suck it up and just purchase a larger turbine/gen set! Trouble is it is so expensive to just get rid of. Maybe you can sell it as being barely used!! Someone else with a smaller creek could use that one. Good luck using the existing equipment!!! Being able to adjust the parameters on the controller is perfect. What’s installed in the control room is suitable for almost any application! It’s just the turbine/gen set that sucks!!!!

The inlet valve coulr be causing cavitation befor the generator if you move the valve back 30 diameters to allow the water to reattach to the pipe you should get better flow over the impellor. Worth a try. Great video best of luck 😊

I used a Scott/Harris reactive for 3 years before giving up... mostly issues with the 3 phase alternators. I had 3 of them come apart before extending the penstock and going to a Turgo. If you really want use the Scott, I do have few suggestions... A tall collection box at the headworks, with a coanda screen works great. Do what you can to increase the head pressure. Install a pressure guage in the pipe, just above the lower shutoff valve. It will tell you a lot about your water system and help you diagnose problems. Don't overgrease the bearings. It can cut your rotor speed in half. I saw that you had a pretty good suction screen, but remove the valve from your Scott, so that you can see into the narrowing throat, to make sure that there are no sticks or rocks stuck in there. I have a few other suggestions. Let me know if you want to hear them.

@Gridlessness Looking at the large scoured areas and the size of the boulders in the channel suggests that that stream sometimes has much, much more flow. I would suggest getting the pipe out of the channel as close to your headworks as possible, while still maintaining a constant downslope. Get your turbine out of the channel too. This will not only reduce the chance of damage during regular rock streamload, but will also reduce the chance of your system getting destroyed by the occasional landslides that occur in canyons like that. A couple of years ago, I designed and built a small weir and collection system that cleans itself and diverts water into the pipe with minimal bubbles. The system allowed about 50 cubic yards of rock, gravel and wood debris to pass and did not require winter service. We can figure out a better way to communicate, and I can share my design with you. Additionally, I live in Washington State and am always up for a good road trip, to check out other microhydro systems.

Here's some theoretical values, like 95% for the wiring from the turbine, 70% alternator eff (maybe not matched well), bearing loss at 99% efficiency, pipe losses (90%) and rectifier efficiency (95%), MPPT efficiency (97%) and the turbine wheel (50%).... 1000*0.95*0.70*0.99*0.9*0.95*0.97*0.5 = 273 watts.

@@MrPizzaman09 The Scott Hydro 1500W Water Turbine is a permeant magnet alternator. It is normal for permeant magnet generators to have distorted voltage waveforms due to voltage clipping caused by the magnetic saturation and harmonics caused by the Irregularities in the Magnetic Field due to Rotor Shape and construction. These harmonics are cleaned up by the rectifier and inverter. The AC current waveform at 16:16 is perfectly normal for a 3 phase rectifier. The harmonic distortion is being caused by the DC filter capacitor charging and discharging between AC voltage peaks with respect to the diodes acting like a non linear load.

The "more bubbles" outlet looked like the perfect setup for a trompe. Depending on the changes made it could be a way to harvest more power easily.

I don’t have a working system but the little that I have messed around I had to start with a larger pipe and step diameter down the further I went. The long run of pipe I believed I had cavitation in the pipe as it accelerated creating an air lock. The old gold miners that washed hills away to retrieve gold used to do this. It helped me.

I believe the problem is in your tail race for the large system. it seems there is not enough space for the exhausted water to leave the turbine without causing back pressure. The back pressure resisting the flow of water over the turbine. Simply put keep the head, the same, but let it exhaust in a space where the water can flow freely. (Not right overtop of the rocks). Let me know if you get the chance to test this.😊

That water wheel in the big system seemed EXTREMELY hard to spin it and the fin design didn't look like they would take very good advantage of that massive flow rate. Seems like it would be WAY better to run multiple of the small ones on the big creek unless you can make a big version of the small one with a big pelton wheel or something.

Now that you have the pickup much deeper. The head and 1st 100 ft of pipe need to be 8 or 10 inch to build speed with the weight of the water, using the same idea as the hydro ran gold monitor's used to blast gold out of the ground 100 or more yrs ago. Going from an 8" or 10" pipe to the 5" will speed up the water and raise the pressure also raising the output by 2 or 3 times.

Love all aspects of hydro power large to micro. Can’t help wondering if your turbine is loosing efficiency with all the air in the wheel from the lack of a draft tube. If you could add one it might improve efficiency. If even a short section gives you any improvement then lengthening it down the stream should add more suction and more power. Wishing you and your family the best. Jealous of your location and the projects it facilitates. I know that draft tubes aren’t used with Pelton wheels and if you had a Francis wheel they are mandatory. Pondering if the turbine you have is more like a Francis wheel than a Pelton wheel.

It was a generator run by a Pelton wheel produced 220, Volts, DC couldn’t turn lights off, but the Pilton wheel we could take the generator off, put a belt onto the saw bench and cut our firewood, the pipe coming into the system was 18 inches by memory, the jet at the end hitting the pedals in the Pilton wheel was about a inch. The drop was about 70 feet. The pipe was 500 m. There was plenty of water in the creek very permanent and being in New Zealand. We didn’t get too much ice in the creek, so went 24 seven at the head of the system was a small dam with permanent gauze and then we put bird netting across the top of that so we could remove to remove leaves which was the biggest problem in keeping it going, especially in the autumn

Good stuff! I could not do better with what you have in the way of test equipment. The solar will never get a lot of power that far North but combining solar and hydro and maybe a backup genset and you could do well.

it might help to fit thicker pipe on the intake so water will go in slowly so bubbles would have more time to escape the system, also T junction on the end when you connect thicker intake to normal pipe with one side standing as a chimney to let the bubbles raise out of the system, also some space under generator could help (escaping water might be slowed down by hitting the rock under too soon so there is some extra resistance)

Not a hydro expert, but a mechanical engineer. To me it looks like the turbulence on the outlet is affecting the turbine efficiency…..looks like the aerated water is partially getting caught back into the turbine blades. Good call on building up the settling pond and getting the air out of the intake.

put a pressure gauge at the pump, use a little pipe (sticking up above the elevation of your inlet) to get any air out, then you'll see if the pipe is the problem or if you just need more head. Do the simple math of psi/pipe size to wattage and you'll see if you are in line with expectations or not.

As long it is not the pipes and nkt the controller then the only factor remained is the alternator generator So to increase that power 50% or more take that giant micro hydro to workshop and fix it's alternator with suitable rpm's until it produces that 2000Watts instead of 480~500 watts with such powerful waterflow, all the best , great work .

My friend the full metal body of a leatherman/multi tool ensures maximum conductivity. Insulated screw drivers are cheap, in the lifetime you may save, you could buy thousands of em. Styropyro has a good video on how electricity can harm you, the good old volts vs. amps.. but In a wet environment ground connections are littered about.

Studying up in preparation to move away from an area where the most reliable source of electricity is sunlight landing on my roof, because I'm tired of droughts and heat waves. A climate where water falling down a hill is actually more reliable than bright sunshine looks incredibly attractive right now. Hydro looks easier to troubleshoot, too. More mechanical, less electronic.

Thank you for the video.

Superb instalment. 👍

Matching the load impedance to source impedance made for best power transfer (or lowest losses). Of course I can see how it would be tricky to get the inverter to draw the right current to not reduce the voltage or cause the turbine to spin to slow.

This is what dreams are made of. Always really like the idea of hydro systems. As long as you have a good flow of water endless power.

bigger pipe to smaller pipe may help increase flow. but the longer and flatter the pipe will rob a lot of energy should increase angle of drop

I admire your efforts and hope you start a go fund me to assist in your efforts.. then, master this and share a refined smaller version with all of us.

Dobra robota! Dziękuję za ciekawy film. Pozdrawiam

That hairdryer test took me back to the opening scene of Top Gun

This just fabulous!! For real...

I’m really impressed by what you have for energy production, however I don’t know a watt from an amp so I was totally confused……..but again, very impressed.

High school physics is not what it used to be. US schools are failing us.

Wow would I love to have that at my house!

Take a whiz before watching this video. Excellent job, folks. Glad to see you had a proper oscilloscope for looking at the alternator waveforms. There is nothing better than the right tools for the job. AND, you knew how to operate the scope. Bonus! (I work with graduate engineers that have no grasp of o'scope fundamentals. Sheesh.)

Dobra robota! Dziękuję za ciekawy film. Pozdrawiam. The expertise you share in this video is incredibly insightful. Thank you!️.

That’s real off grid wow nice project 🇳🇿

Coanda screen will enable only particles small enough to pass through the jet so no more clogs like those. This video is a good way to demonstrate the importance of sufficient design on the intake in order to secure sufficient flow and pressure of clean water for the required output. A permanent weir with a Coanda screen on it from a pool where the flow is curved so "most" of the detritus bypasses the screen. Maximizing the time between maintenance is proportional to the sustained generating capacity

Nice work Jeff.

Great video guys thank you

Funny I have not seen any of your videos show up in my thread for some time. Had to go out and make sure you were still making them.

Remote rural NSW Au here totally off grid unfortunately I dont have a water source as in river or creek but understand the principals you are employing, solar and wind gen here. Understand the fluid dynamics water will always find the lowest point and a few small turbines introduced into the system works. I have thought about a pen stock pumping water into it during the day then reversing the system of an evening , havent set that up yet , workable though with the drop as in feet per pounds flow. You have made me get up of my butt and set that configurations up. Have some old washing machine motors ( I know that sounds archaic ) to put into system then convert the AC to DC, I run a 24V system its adequate for a three bedroom house out gathered sheds and workshop . So wish I had a river and I know its doable without a river or a stream , I tap bore water here. @18:30 Morning Star nice better for my system than the Tri Star version as a voltage regulator, I run both, regs., its not just the price difference as basically they are the same mppt tech but different in subtle ways and I know its the same company just manufactured in a cheaper country, or they where guess looking at your system its the best available on the market, my system is five years old since the last upgrade about a month ago, but I digress have been told I do that. See the disappointment with 230 watts less than a 700W causes me concern and the amps on mppt not much there, sorry 2 rain on the parade. Yep those voltage regs are designed for solar and wind just watched the end didnt even think about that the din switches setting need 2 be set for the applications ..I did notice no wind turbine I run a cheap one and it keeps the batteries topped at night just a thought prolongs the life of the batteries and these days they have become the most expensive part off an off grid system...............Aggggggg, will see myself out good people.

Yes, the TriStar MPPT used seems to be designed only for solar and not pico hydro which is probably resulting in poor impedance matching for the Scott Hydro 1500W Water Turbine

Your channel is a never-ending source of learning, beauty and fun. Never thought I would be interested in smaller scale hydro-electric generation, but Kris Harbour Natural Building was the first time I saw a utuber exploring the subject. Even more so it is your entire family’s spirit of exploration into self sufficient solutions that I have found so captivating throughout these years. Again, thank you for a fine video and may God bless you and your endeavors!

There is a bit of cavitation, build a big collector for the water like a dam, you could thottle up the water and increase the wattage...

I can hear in the video that the water wheel is not spinning optimally. It's going, cha cha cha, likely the source of sub production and the weird wave form. Reading some of the comments, seems others heard the same. Also liked the comment about the valve being too close.

I have micro hydro, 300' head with flow rates that go from a trickle to a torrent depending on season. Solar is crucial in long dry summers, I love the quiet and lack of moving parts during that time of year. However the best improvement in getting through periods of low power production was upgrading the trash lead/acid L16 batteries to LFP's. Way more efficient, no wasted power boiling electrolyte, twice the lifetime at half the price. Highly recommend.

better yet, toss the batteries and set your system up correctly in the first place.

응원합니다. 에너지 독립 ~~~

sending love, wish I was there.

Air escape spouts along the pipe will get rid of the air? That is my armchair analisis that comes from watching other homemade systems. 👍My work here is done.

You pretty much have to fix everything. Get the dam in order, and get a clean intake. Loose the squirrel cage, and get an adjustable francis. Dont put a rectifier without power correction on the 3 phase. All in all, just plan it all out. You will get a lot more power, reliability

17:14 please give the output head more clearance to discharge the water. The splash back could be bogging up the discharge potentially causing lowered efficiency. You're inspirational!! 😅🎉❤

Thanks

you should measure the generator ac power factor on each phase, its likely inductive & simple rectification is clipping the reactive power potential, adding some reactive compensation pre-rectification (likely 3 phase cap) and some post rectification smoothing (DC caps), you could gain as much as 8-12% more power!, this is often overlooked on hydro systems

If you get the intake for the smaller system off the bottom of the cistern... to half way between the surface and the bottom... and have a flow out from the top of the cistern to self clean any floating debris.. then the intake pipe can be drilled with a myriad of 4mm holes and closed right off at the end... with a shade cloth filter over the small holes (as a last ditch effort in case anything can get to this relatively clean stratus of water).... since as you saw all the gravels and sinking debris will be on the bottom of the cistern.... This also eliminates air entrapment as the small holes do not create a strong enough suction to cause air entrainment or a vortex from the surface drawing in air.... So''' self cleaning on the top, self distribution of sand, gravel and sinking debris on the bottom.. clean water in the middle No more blocked jets and no more bubbles in the line.....

Prayers

Add a few air vents before your last valve downstream. That will let a majority of the air out ahead of the turbine and speed up the water flow

The valves you added need a air filter because it is sucking more moisture from the air and the air intake starts fluctuating like a bridge over Royal Gorge

Cool setup

I was hoping that this was your place. We always love watching your channel

More power Scottie more power

Split the pipe in to 8 even sections. 24", 20, 18, 16, 14, 12, 10, and then 8,. You'll see quite a bit more pressure. You could also do it by joining lots of pipes down to one. You'll need to reinforce how your pipes are secured.

I'd look at the clearance around the discharge on the 850W hydro, preferably mounted with a few feet of clearance below the discharge point. If the water cannot flow away readily, it could be creating back pressure at the discharge.

6:19 in...note to self, use multi filtration devices with graduating stepping methods to ensure not every 2 minutes.. "Oh now that ones clogged". This seems like not an everyday used thing due to how easily it get clogged you'd need to go down and make adjustments every few minutes.

Hydro power is all about the difference in elevation between the turbine and the water source. The more drop, the more pressure at the bottom of the pipe.

Excellent !

lovely rivers

Jeff is always impressive sharing his years of skills and talents... and awesome friends 🏆
