Thread: Dual Voltage Perenties. Do you use the 24V side?

Aaanyway ... I currently use my 24v system to power the rear FFR working lights and part of the vehicle security system. Both could easily run off 12v.

So mine is waaay under-utilised.

Giving serious thought to pulling the 24v generator and power box and going with a Traxide 12v multi battery solution.

Reluctant to mess with the OE FFR spec. But in all honesty I dont need it.

Whats the spec of the 12v alternator? Would it handle 2 of the deep cycles ok?

Two things come to mind, the primary fuel source for a hydrogen cracker/generator is water which is far cheaper than LPG and when you already have an excess of 24V power you are utilising an available excess resource to make the engine more efficient.

On the other hand we don't know what Brad 56 is using his for.

People with diesel gas or diesel liquid injection LPG are reporting that they are a gear better off on hills and the cost/km drops. Don't know if that remains the same with the excise going onto LPG

While the water is technically a fuel "source", its not what the cracker is running on.

Does the 24v generator have a clutch to unload the engine when charge is not needed?

Or is it loading all the time? If so where does the excess energy go so as not to cook the batteries? (other than a hydrogen cracker, which some of us don't have)

Now if we had a solar panel on the roof powering the cracker (via the 24v system), then it would all start to make sense!

We're still waiting for confirmation of the use of the hydrogen generator.

THe CAV-Lucas 28V alternator does not have a clutch, but I'v always thought it would be a good idea. The usual practice is to remove the belt when the 24V system was not needed.

Yes they do cook batteries.

Bugger.

Guessing my 100mA or so of constant draw won't be making much difference.

you are starting to sound like a free energy nutter Diana. You don't get something for nothing.

I was going to fit a perpetual motion engine, but was worried the noise of it spinning would keep me up at night!

I can see where that would come from, however LPG over diesel has more complete burning of the fuel and when you look at their exhaust pipes they are usually grey rather than black from most diesel exhaust pipes. So if there is a more complete burn of the fuel, it is by definition more efficient. (Not necessarily cheaper)

The LPG is not a free input and the cost of the installation is significant. Hydrogen is also not a free input, but if the cracking/fuel cell technology requires and electrical input and you already have an electrical supply with surplus output (or you could consider it a parasitic load) why not use some of it to make your fuel burn more efficient/cleaner?

If you read the bit I quoted, it was the talk of "free" or "surplus" power from the 24V generator.
