Well, that solar Earth place seems to have a 7kw unit and on the 2nd page they hint at an 18kw but couldn't find a part number. I did not find anywhere on their website a reference to the quality of the output voltage. The meeting last week was a no-show, but I'm definitely keeping this good...

What a terrific idea. We were going to have a meeting today, I'm going to bring this up.

I can tell, you really think it's important on the why. I don't really know other than it had something to do with their initial funding which is mostly spent. (the squirrel-cage is an old joke, I was trying to inject a little humor) What they are trying to do is marry an Edison style...

In Edison's world that would not have been possible, and we would have vast amounts of pollution as a result. In Edison's time each generator was powered by coal or hydro. If we continue with the large power corps. running our world we will soon run out of resources. IMHO we must get off our...

I was not consulted in the choice of the size and capacity nor the type. 500vdc@50A was decided upon for some historic reference to Edison and that those early designs are now public domain. I'm merely assisting in adapting the power output to match to what a typical house requires as they...

I found an abundance of designs with no specs, that's why I came to this forum. I'm using or going to be, this generator for main power. I don't get to have a constant-speed drive shaft either, and there is no motor. I had thought of putting squirrels in a cage, but haven't figured out how to...

Oh, ok, I saved and filed that but wasn't sure if the vla504-1 was what you meant. thanks for the pointer on 'smoked' parts. Wave-shaping, how'd you guess that was my next topic? Do you think a saturable-core transformer might work?

Is the bg2b powerex bd the recommended drive ckt and emergency shut-off you are referring too? These are some pretty slick gadgets, had no idea stuff like this was available. thanks!

No it's not an alternator. Can you suggest some igbt's big enough to handle the job?

I have a 500v, 50A dc generator (~25kw) and need to get 240v ac (rms) for operating typical household and shop appliances including those sensitive to quality of the ac. (this 240 would be run through another transformer for 120v appliances) I've found an abundance of information on various...
