It looks like 3 lines out of each box, but yes I will need to convert them to 3 single phase 240v lines if this box doesn't do it.


I really don't want to carry batteries up this hill, mules can nly handle so much.

I have enough to use 7000/8000 watts easy, but I am going to start with one at 4000 and heat water tanks and yes a pond/ pool to absorb any extra load. don't want to mess with adjusting water flow, the Electronic Load Controller or the THES A2 below seem like the way.

something like this http://www.alibaba.com/product-detail/Electronic-Load-Controller-ELC-_116357027.html

or this at 3k plus 4 relays http://www.smallhydropower.com/A2_%20Version_%200.3.htm

OK, I think I know enough to check what's available locally before importing anything.

2 of these.

I have plenty of head and water flow to spin these stabilly, so i guess i'll start there and see if rectification and a battery bank is necessary, if the AC is too wild. What is the expensive way? if it weighs less than batteries it could be the move.

Thank you Joseph and Dillon,

It's for a home and i want to run audio electronics off it that would be hard to replace, the voltage in the country is 240 and that's what my 2 little generators will spit out at the highest RPMs which I should be able to reach easily.

I will need a load controller to keep soaking up the juice to keep it at 50 or 60 Hz from what I understand, as I said a water heater or 2 will be the soaks.

I am not sure how stable the voltage will be compared to rectified stored and inverted back to 240. I basically need 3rd world standard 220/240 and nothing too sensative, but I want to protect anything that gets plugged in from swinging voltages.

I guess the best thing is to set it up and measure it and then see thanks for the tip on power line filters, will definitely install those. I may very well be able to use it stright.

Since all systems I see have a charge controller and a lot of peripherals for the battery, I was hoping there was a load /charge controller that would run the AC system but it seems they all require rectification. The generators have a single winding 12v tap each which I can use to run the controller rectified and to charge a small battery.

It just seems like the controllers need it rectified to do their controlling, whereas I just want it to read the AC and keep the cycles even at 50/60Hz.

Looking at this http://www.homepower.ca/ac_hydro.htm I seem to only need a Load control governor and filtering /fuses plus the additional meters I want. Does it appear that way to you guys?

Thanks a lot for your guidance.

Well It would be nice to have 3 phase 240 from the jump, I have step up / step down transformers so easier than anything. plus the generators are rated at more watts at 240v.

the power conditioners I saw were rather expensive, it might be cheaper to rectify and have a small battery. Question, if I have say a single battery (say car battery sized) and tap my power from there will I be able to use the full 8000w? all coming through the battery? is it gonna dry up on me alot? It seems like the battery could be a choke point and cause problems. The soak load will be a water heater 8000 or 10,000w to handle the full load.

So no one conditions the AC from a generator direct? Rectifying then inverting seems a waste but if it's cheaper than conditioning it might have to do. If the rectfier and the inverter can handle the wattage, how small can the battery be without causing problems?

Hi everyone,

I am planning a micro hydro system, and one detail that is hard to parse is when you do AC direct, you can have the load controller maintain the frequency, but how do you get clean power?

Most systems I see discussed still have some batteries and tap their power from inverted DC, which will be much cleaner than the AC direct from the generator.

some details, 2 x 4000w 240v triphase output, I'd like to just condition these lines and use that in the house, but I don't see much of this looking around, and the conditioners I have found seem rather expensive compared to inverters.

So how can I run clean power AC direct without batteries?

Will a rectifier and inverter essentially do the same thing for less with no battery or a small battery?

Thanks for any ideas.
