Re: Another Auto Alternator system

 Thanks for the response, Flux. My computer went onn the fritz and I am now in Florida, on my newer backup laptop.

 My thinking on the PMG was, it may not get a high output, but, it will eliminate the switching in and out of that wound field coil. Ele...

i liked the look of verticals but the price they paid !
the price is ridiculous .
only governments can justify  overpriced mechanisms like this.
 somebody is related to somebody or is sleeping with someone who is
maybe both.

They might get 1 kw in 16mph wind.......

However the Install costs..........

If you want a solid state version you could do well to look at Ghurd's controller.

 I have spent a lot of time on the interweb looking for info and all the stuff points to this site and Gizmos site as the Place to get the best info I am going to try and build his controller I have the schematic and will go for it.

Hello, Welcome to the forum.

Glenn (Gizmo) runs the Back Shed forum down under. Lots of great projects and kind folks there.
This link should help get you to the controller page.

What do ya say we put together a field trip and head over to Paris to see it? ?

I want to build my own charge controller. I would like a schematic and a parts list . Gizmo has a  schematic a parts list for that would be nice. Thanks for helping.

Re: A look at Peltier cooling

Wed, 02/25/2015 - 11:09
"Bang for the buck" efficiency is fairly important in this project, as I only have a middle-aged 100 AH deep cycle lead acid battery supplying the trailer, and about 30 W of solar. I'm starting my reading on a LiFePo4 pack project, but that won't mater...

I will certainly be keen to see how well the water cooled unit helps in internal cool down once the door has been open.
That seems to be one of the biggest drawbacks of the TEC fridges.
I have been amassing heat pipes from older HP Laptops for a try on...

Re: Pure sine wave inverter

Getting away from the original question, but I have noticed 2 schemes used with these msw inverters, The first ones I met regulated the dc converter to 320v (UK 230v supply), then used a fixed pwm on the H bridge.

Most of the present ones seem to use a...
