Hugh,

That's good feedback. Thanks for posting.
Are you burning dino diesel only? or are there some "alternative fuels" too?.... like veg oil.

A couple more questions.... 

How many hours per day does it run?
Driving loads directly ?  or charging a battery bank?

Cheers,

Glort, why bother with grid connection or spinning meters backwards?
Consider running your panels to a battery bank, then to an inverter which powers some dedicated loads that are always on and powered only by the solar.
Maybe a freezer and/or a refrigerator, lower element in the hot water heater, night lights, etc....
It's the same as slowing down your meter because you are removing those circuits from your grid system.

just a thought mate,
cheers,

Hi All,

Anyone know a source for 8 ribbed serpentine pulleys ?

I am looking for:
8 ribs
6.0" diameter
1" bore ( or taper lock bushing style )

This is to match up with the 8.34", 8 rib serpentine pulley on my ST-5 generator head

Thanks,
veggie

PS: I think it would cost me a small fortune to get one custom made locally

seashells,

I have a Listeroid GM90 6/1 and I am very happy with it.
I have had several Listeroids and this one is the best quality of the bunch.
A big advantage that these engines have is the crank driven oil pump which feeds the con rod bearing with pressurized oil.
I imported and sold about 10 of these engines a few years back. They sold for between $1400 CAD and $1700 CAD depending on options (some had electric start).
I would not have any reservations buying on of those.
If you have any questions feel free to PM me.

cheers,
Veggie

Thanks 38ac,
I must give much credit to a fellow I work with who is a great welder.
He stitched my base parts together with lovely smooth welds.
A very useful skill.

I just completed my latest Project...
The engine is Changfa style R175 and is coupled to an ST-2kw head.
This is the first unit I have built which is directly coupled without a belt drive.
To accommodate the power pulses I sized a shaft coupling capable of 30HP even though the engine makes 6hp.  
For 60hz power the engine must run at 1800 rpm, however I would like to slow it down to 1500 rpm and generate 50hz power.
This should provide quieter operation, lower fuel consumption and maybe longer engine life.
Apparently the IOTA 55 amp charger that the ST head will be powering accepts 50hz power.

There is more discussion on this subject at the following thread...

A couple of questions relating to ST performance...

What is the typical VOLTAGE output of a single phase 60 hz ST2 head wired for low voltage? is it 110V, or 115v, or 120v ?
Is the relationship linear between speed and voltage on an ST head ?

The ST Head will be driving an IOTA 55 amp, 12 volt battery bank charger.
IOTA states that the charger can operate anywhere between 50hz and 60hz.
Allowable input voltage to the charger is 108 to 130 VAC.

The engine/generator are direct coupled at 1800 rpm (60hz) and the engine produces far more power (and noise) than needed.
I want to know if I can slow down my diesel & ST Head to 1500 rpm (50hz) and still charge the batteries.

If the speed/voltage relationship is linear then I could theoretically reduce the engine speed to 1500 and still charge batteries and make 50 hz. power.
But the resulting voltage would be too low for the IOTA charger.
eg:   115 volt X (50/60) = 95 volts.... too low for the IOTA

so.... in order to get at least 108 volts, I would have to slow the engine down to 1674 rpm or 55 hz.

That is ... IF the relationship of ST speed and voltage are linear and the initial 60 hz voltage is 115VAC (or is it 110v ? or is it 120V?)


Thanks,
Veggie
