I didnt realize that it would be that inefficient. Understood. Good luck with it. Just my own observation. Most ordinary cable is good for 250V or so as opposed to the 12 or 24V ? of your batteries. If you have an AC generator, it's very easy to step the voltage up for efficient transmission of the power from the waterwheel to power shed. 10 times the voltage = 1/10 the current = 1/100 th the power loss for a given cable gauge. Even with DC it's very much worthwhile using a simple inverter type solution to do the same.

I don't know where you live but here in the USA, just about ANY Electrical Utility Wire that is UL Rated, will have a 600V Insulation Rating......

I thank all of you who took the time to answer my questions and give advice on the design. From here I just need to do a bit of measuring and math to figure out the size and length of the wire, but I think I need to know what the PMA from the honda puts out first. Im going to take a no load measurement of voltage at various RPM's when the machine shop has the flywheel shaft built. Untill then...

Im going to take a no load measurement of voltage at various RPM's when the machine shop has the flywheel shaft built. Untill then... Once you know the output of two of the wires you can calculate the total output by multiplying that by the square root of 3 (1.732). Once you rectify it and use a smoothing capacitor you just read it with a DC voltmeter. BTW the 3 Phase Basics link shows two different ways to convert it to DC. Either will work with Delta or Wye. The bridge rectifiers tend to be a little neater and it's pretty easy to find them with the proper current and voltage range. Make sure you use heat sinks. Those six diodes may look complicated but it's just three sets of two diodes connected in series and then joined at the ends. You simply connect each of the three outputs leads between one of each of the two series diodes. The top (if you have the bands on the diodes at the top) is now Positive and bottom is Negative. Connect a polarized (DC) capacitor from Positive to Negative (the stripe on the capacitor is Negative). Make sure it 's rated for 300 volts or higher. I'm using a 270 uF capacitor but 100 uF might be enough. Dave Similar Threads Posted remote micro management December 18, 2007, 11:45 pm Way remote power source help please!
