I purchased DC-512 four alternators over the Internet for a hydro project. I’m taking advantage of an existing irrigation system on a farm, which pumps a steady stream of water with great pressure at a very long distance. It’s like a fire hose in action.
This system is running continuously for 12 hours daily. I’ve designed a special, very light aluminum=blades arrangement and I have adapted it to the DC-512 via belt drive to disrupt the powerful irrigation water stream, moving this blade as when cleaning a painting roll with a pressure hose. This creates a speed in the DC-512 of 1150 RPM as measured with a tachometer. The voltage produced with no load, e.g., disconnected from the batteries, is approximately 25 volts, measured with a Flux digital meter.
The DC-512 were all connected in parallel to a single 12 volts Flex-Charger of 100 amps to charge a battery bank, 4 batteries connected in parallel. Three alternators DC-512 were disconnected from the charger to perform troubleshooting leaving just one connected in parallel. This is what happens; when I connect the positive cable to close the circuit, seems like a short circuit is created in the alternator, which slows down the speed to about 500 RPM stopping the blades and disrupting its function to load the battery bank. The charger light turns on indicating that is charging but, producing only 13 volts, which is not really enough voltage to charge the batteries. I have connected everything precisely as per alternator and charger instructions. Finally, I am tired of getting wet like crazy during test and troubleshooting process. I wonder if you can explain what is happening and how can I make this system work. Your help will be really appreciated.
Thank you in advance.
As it states on the web site, we can not answer specific design questions as we do not know all of the specifics of your installations, and this is a free site and we have limited time to spend on each email question. However, we can provide general answers that may be of some help.
First, I assume this pressure flow is due to gravity head and not from a pressure pump somewhere. Second, if I had this much “free” water flow I would purchase a quality hydro-generator that is designed to maximize the conversion of energy. Most likely a properly sized and designed unit could replace all four of your home-made units and without all the problems you are having.
If things work fine with all four alternators in the circuit and then when you cut out all but one and it does what you describe, it sounds like it is being over-loaded. This would drop the voltage while appearing to be under load. Also, your wiring switching to one alternator could be causing the remaining alternator to be sending power into the alternators not being used which would be a large current drain on the working unit.
Again, you have a great opportunity to power your home with this much hydro power if you bite the bullet and purchase the correct equipment.
