Chris' I agree with you 100% about not wanting to spend much on a system that I hope to completely replace one day, do so with a system that will pretty much take care of itself.

How about a transformer from a metal halide lamp fixture

the Ac units draw about 45 amps @ start up  roof mounted Dou-therm 15 amps run. my inverter can handle the  1500w heater at least 1 of them but we hardly use the heaters unless the generator is already running and we are cooking

I was going to build a soft-start for our neighbor using some resistive heating elements in series with the transformer primary, and that could be switched out and bypassed once the transformer came online.  But he said forget it - he just bought a dif...

I have a source for soft starts if interested. up to 30 amps if memory is right... could replace relays with larger too http://harbachelectronics.com/shop/misc/ss-100-240-universal-soft-start-module-copy/  20 amp complete version http://www.ameritron.c...

No it just means with the weights in place, there is enough pressure on the coupling to create enough friction to pass some power through and drive the bottom weight around. The only test to see if its actually working it to draw power off the bottom a...

I did a simple test today. I took all the weights off and started the motor. The tilt plate just moved up and down and did not rotate. The output shaft is definitely powered by the weights falling toward the the center of gravity. No weights on the ti...

I bought a Trimetric 2025 a few months ago. They are nice and simple to use as a gas gauge. When mine arrived, part of the display was not lighting at all. The company took about 5 days to repair and return it, including shipping time. They were great ...

I got it to work with a Classic 150 with no step-down transformer.  Hydro Mode didn't work all that well.  I am using a power curve for a wind turbine and it works beautifully.  Although it's not really much of a power curve because it's pretty flat.  ...

I should've said that differently.  Yes, they are in series but each coil is excited with an opposite generator pole....

you can also connect a 1:1 isolation transformer as a 1:2 step up autotransformer, and it will effectively double its "rating"

so a 1KW isolation transformer will be good for 2kw input and a 1900 watt output is probably realistic.

lol, if you can get...
