Budget? **You have some testing gear? (oscilloscoop, voltage/current meters) **On what rpm is the generator running and how many phases? Alternative you can use a toroidal or other type transformer like most of us to convert your low voltage AC to 120VAC. Both possible with the egs002 module. OK, Lot to unpack there. Let me get you guys up to speed. Yes, I have basic testing gear. Not really on any budget and I do have a lot of parts as well as transformers and a big toroid that might be perfect. Now on to output....Where to start?. The gen is really a neo magnet alternator. 12 coils (6 pairs tied together, usually) output 6 phz AC @150 to 300 hrz. at speeds up to 3200rpm with a sweet spot near 23-2400rpm. Thats a mouthful. This will produce a noisy sine wave on my scope but believe me its a mess. Each coil and core can vary slightly making it difficult to "blend" these AC freq. together properly. However, I have powered a bunch of incandescent light bulbs @ 900 to 1000 watts for extended periods of time. I have powered many of my collection of stepup/down transformers also with varying results. Always an iratical, inconsistent, "inefficient" (IMO destructive) sinewave. I chose to try DC. I added a full wave bridge rectifier to each coil.  It just made sense as I can add small caps on the AC side to trim each coil for a more consistent voltage or the DC side to filter. So far I have only wired 2 opposing coils for what I call my 50-60vdc range and tested independently with a load.  And when added in parallel, produce no voltage change but add in amps to the load. This seems better. This is where I`m at now. Is this to much to digest ? I could go on.... Can we add pics here ?
