With 4 nozzles and plumbed into the big line that other turbine is hooked into, that thing would be way more efficient! Theres a reason why commercial pelton turbine plants have like 5-6 nozzles. But i guess you cannot run the big line for very long due to limited water supply. You mentioned in the chinese water pump turbine video that it was a tank and not something like a dammed up creek or such.
Hello Miles, nice to see you again, this is good result for this turbine. I have the same POWMR mppt, the number it give is very "generous", at home 15 to 20% more than reality. this turbine will be better with more cups. From the 1 inch pipe, it look like you dont have a high presure, may be the pipe or intake is damage ? Today, my pelton turbine is producing 850W.
Salut! Ça fait longtemps, dis donc :) 850w, wow, that is good going and a very useful source of energy. Yes I think maybe my feed pipe is possibly a bit damaged or possibly has a stone in it blocking it somewhere. I shall have to investigate that but we've had so little rain lately it could even be that. It always rains during the holidays in Wales so I just need to wait for the next one.
Ideally for a efficient turbine a pelton runner should have a minimum of 16 cups. This one only has 12 hence too large a gap between them. I suppose for the battery charging capability output you are looking for down the mine it isn't critical.
Hi Miles , brilliant whet you have done I see in the video where you are being interviewed I noticed you are using the same MPPT as I have but what do you use for the load dump bypass when your battery are full as I want to install a pelton wheel to my solar system
Viktor also supplied my 4kW turbine, with a 50m head 1.5inch pipe I am getting 85V but only 0.15 - 0.2Amps, what could be the error? Using a 3 phase rectifier same as you, wanted to directly tie it to the grid with a 1200W inverter.
a 50m drop with a 1.5" pipe and you're getting like 12 watts??? Something very wrong there. Is the pipe quite steep down to the turbine or is it a very gradual decline? Are you definitely measuring it right?
@@TheAmazingAdventuresOfMiles it's a 200m pipe, Viktor send the turbine specs, at 80V it should have an output of 800W but the on the meter it only shows 0.1A while it should be more like 10A, is the cable too thin so the Voltage stays high but the Amps don't pass thru? Measurements confirmed with a second meter on the inverter. Thanks for your thoughts!!!
Hiya, I just used a basic one from eBay, I think it cost about 10 pounds. You can make one with six diodes if you have some to hand, that's all they are inside, but I prefer to buy ready-made ones as they are already potted into a housing with terminals and such. If you put "Three Phase Bridge Rectifier" into eBay loads will come up, they are all fine really. If you're dealing with a lot of power you can run lots in parallel.
