I am new to this forum. Hello to all. I am preparing to install a small off-grid hydropower system in Chile. I have head and flow for about 2kw; however, the...
That would be a very large quantity of water with a significant head to generate any appreciable power. How is the water pumped today? Gas/Diesel, Solar or...
jcunningham: I saw the video, allowed by the moderator, . The design clearly shows that no power calculations were made to optimize the generated power (...

Charles: Why don't you give the hydro parameters to determine what would be the best arrangement. It seems that a high voltage 3 phase generator may be the...

You rectify the AC into DC at the battery location. Jan ... From: whitcity3 To: microhydro@yahoogroups.com Sent: Tuesday, January 01, 2008 4:26 AM Subject:...
... battery bank and ... Hi, I use a similar system and this information would seem basic to find but I had a hard time with it, I know Nando knows far more...
I have just been to a short wind turbine workshop at http://otherpower.comin Colorado. Dan Bartmann told me that DC is just as good for transmission as AC....
Xavier/ Christopher Sub artesian wells are usually described as a spring or bore that can have water at the surface, or free flowing but with no pressure,...
... A good summary of 3 phase, thanks. I'll add it to my bookmarks. I'm building a 6 phase transmission system now for a turbine / alternator some 800 feert...
Hello Jan, Thanks for your response. The well has not been sunk yet. The area tends to be flat. Wind is an option and Solar will work they have sunshine for...
Interesting links, thanks for those. ... Is this capacitor directly across the output? Which is also directly across your battery? If so, I am interested in...
Oops. I should have asked what frequency are you generating the AC at? At higher "ripple" frequencies I could see the capacitor helping out. Re your comment...
Hi Brian, Just to clarify that a bit, DC transmission will use less copper for the same power loss compared to 3 phase AC feeding a rectifier that produces the...
Charles, Nando's ask is a must: head an flow are need for best hints. Your 2 kW power site is some low and for AC generation it's not easy available generators...
Bill: Why are you building a 6 phase system, can you detail it? For such distance it is best to have a high voltage generator and not more than 3 phase ( 3...

Nando et al: The hydro parameters are: 4 inch penstock, with static 95PSI and 300 gal per minute at the bottom of the penstock. I could put in a larger...
I am wondering if anybody has used the "Peak Load Shaving Mode" on the SW invertors. I am wondering if I can use this mode instead of rectifiers for power...
Another approach that is really excellent is to generate single phase AC at controlled voltage and frequency and feed it into the 'generator input' terminals...
Hi Charles! ... Where are you? I'm presently installing one, halfways between Temuco and the Llaima volcano! ... For that distance and power, I think a 220V AC...
... Thanks, Dave; Now it gets shakier, & I'm going to need some help on this. I don't know how to measure the frequency, and didn't think it really mattered ...
Charles: Since you are in Argentina, do you speak Spanish ?. 95 PSI =67 meters 300 gpm = 18.9 liter/sec Since you did not define the length of the pipe, no...

I have been working on designing a pelton turbine. I have found a lot of dimensions and ratios of cup to jet sizing on the internet. The one thing I can't seem...
Hi: I don't know if it would be simpler but is it possible to put the batteries down near the generator/alternator & just run the line voltage the 300/800...
