Listeroid Engines / Re: My fix for Listeroid light flicker
« on: May 14, 2022, 03:20:33 PM »
Thanks Cujet,

The weak point at the moment is the batteries. They are 9 years old.
They hold a charge and perform well (about 85% of their original performance), but their days are numbered.
I considered switching to IiFePo but I'm not sure if an alternator can charge them.
Perhaps the BMS takes care of that problem. I will need to do more research as the time gets closer.




Excellent tips !

Thanks again,

"The best ones have acceptable waveform and voltage regulation by the stock harmonic system, though I expect THD is still about 15%."

Thanks BruceM,
Just to be clear, do you suggest not adding and AVR until the unit is installed and the output is evaluated?
If I was lucky enough to win the lottery and get a "good one" then no mods may be required ?
(Other than the usual bearings, Junction Box, and tidying of the wiring)


Generators / Solid State AVR on an ST-3 Head - Any need for it ?
« on: May 08, 2022, 11:34:00 PM »
These voltage regulators are available all over EBay and Amazon for anywhere between $10 and $30.
Are they any good?
Are they even necessary?
I would think that sine wave conditioning would be a better product to push for the ST heads.
In any case, If any users found a benefit from installing a solid state AVR on an ST heat, please pipe in.
I have an ST-3 and I'm wondering if I should add an AVR ?

By the way ... what currenty controls the voltage on my ST head ? just the engine rpm?

Thanks for filming that Powdermonkey.
Amazing what floats around in the oil of a "NEW" listeroid.
It would seem that any filter is better than nothing. Regardless of the type.

Engine/Generator --> Battery Charger --> Battery Bank --> Inverter --> Clean Power

Should work.

Humble suggestion.....

Your bookmark may still be directed to the old URL address.

Manually type        and try it.

If that works, bookmark the working page and delete the old bookmark.

Very nice Build, Neat and orderly.

I'm looking to build a similar system to work with my solar panel system as well. It looks like you are using the mppt75 charge controller from you single wire alternator, is that correct? Did you install a two conductor lug on your single terminal of your alternator?  When you integrate the solar system, I assume it will have it's own charge controller tied to the same set of batteries. Which Magnum inverter did you use?

Sorry for all the questions, kept pausing the video and tried to understand how it was all wired together.



The 50A alternator is wired directly to the batteries and the uses the voltage regulator in the alternator to control current/voltage when the engine is running.
The "Intronix Power" 25A, 24 volt solar charge controller (CC) is not connected to the alternator in any way.
Solar panels connect to the input of the CC and the the output of the CC is wired directly to the battery posts.
So, two separate charging systems connected to the same battery.

good luck with your system build,

The Microcogen site was updated.
Thanks MobileBob and Hwew.

I am unable to login and cannot get a message to the host in orde to advise of the issue.
I tried on various computers, but I get an Error message as soon as I click the Login button.

Anyone else having issues?


It is still available.
Yes VERY operational. Only 5 hours on it for testing functionality.
Please use the forum message system if you require further information.
I will send you a PM


Generators / Small Permanent Magnet Generator
« on: April 24, 2022, 03:34:05 PM »
Hi All,

I came across these little PMG generators.
I know there are some members who have been looking for such things.
Probably low quality. But they are cast Iron, and with some care and slight mods, they may be useful for some projects.

Hugh,  I'm thinking you may like this little unit  ;)

One thing you may want to investigate is freight costs.
Shipping container prices from China have jumped from $12,000 to upwards of $30,000 per unit.
Then there is the shipping port costs, handling fees, and land transport to your location.
The good old days of cheap freight are gone.

Generators / Re: Small 900 RPM Generator heads - do they exist ?
« on: April 18, 2022, 05:45:45 PM »

900 RPM single phase and 3 phase electric motors are quite available.
The problem as I recall it, is that an electric motor converted to a generator (with the addition of capacitors) is only effective at the load point that matches the capacitors  ???
So it can be done easily enough, but a constant load point must be maintained.

Generators / Small 900 RPM Generator heads - do they exist ?
« on: April 17, 2022, 02:12:26 AM »
Is anyone aware of a supplier of 8 pole ( 900 rpm ) generator heads in the 2kw to 5kw range ..... anywhere on the planet ?
I would like to put one on my Listeroid.

Oh ! ... and if it's not to much to ask, I want 120/240 AC split phase  :laugh:
