Jim and Matt, yes, that the spirit of this CHALLENGE.
It ain’t about all-the-world-over comparability or bragging rights.
It’s about you, yourself burning/learning by actually using for you, and yours which you will be doing anyhow as a matter of daily living/providing.
After reading this whole topics exchanges now I’ve decided NOT to put up my actual use numbers. This will only drive the idealisms fires.
I will give practical’s learned though.
You’ll only ever get all of the fuel out of these Chinese Yammer-clones by corner tip-up mounting. These need air flow up from underneath anyways so I put mine in a square of plywood with a 2" block under the diagonal corner from the fuel-shut off petcock.
Then all of the fuel will be used up out of the line and carb bowl. Important for me as all of my set up system are unattended and fuel/heat turn themselves off.
Just like I woodstove.
Now able to get 7 hours at 1/2 load of 500 watts on one tank of fuel. I can only get slightly less than one gallon in mine even level mounted. CA version I’m thinking with the additional cannot fill vapor recovery space.
Just as the owners manual said it has taken 25 hours running to get this completely rings seated in.
Honda EU2000i is now getting a soild 10 hours running at a 400-500 watt stabilization loading. Rated .95 gallon tank. Now with the fuel shut off split out from the ignition turn off I am able to run out empty all of the four fuel lines, pulsator pump and carb bowl to dry/safe.
Partial filling the tank. Then hand cranking over to fill these. Then I can squeeze in the remaining one gallon up to the neck for a true one gallon filling.
And this give you the systems fuel use comparibilty.
Output power is a different story.
The inverter/geberator unit is frequncy clean, clean with a real stable voltage. Overloaded it just shut itself down. Idles. Waints for a manual turn off, reset/restart.
The AC/synchronous capacitor/field set up like all of these new AC cheepie’s: load-on, load-off swings the voltage from ~100 to 140 vac. The engine speed governor system fights enough to swing the hertz ~55-68. Worse. These two systems then occolate and fight each other into seconds duration stability. Overloaded is actually a stable condition but with “browned out” low frequency and voltage. Means heat build up on the generator windings side and the loads sides.
Brush type synchronous gen heads with a variable active feed-back field strength controls are just so much more able to keep the output voltage stable.
Goota’ love your old systems if you have one. Use a brush type daily and they will never hang-up!
Absolute key to getting these kinds of run/fuel use hours is keeping these system “heat” loaded down to run clean and most efficient! That unloaded burbling is actually cylinder cycles miss-firing.
Pee/stinking ito yours and mines airs with passed through HC fuels and oils!
Pocket emptying looting you out of your had to make/buy/acquire fuel stocks. That cylinder cycle NOT firing/power contributing then dragging existing rotational energy out of the engine/gen head systems. 2x then the energy you have to put back in to make the rpm/power on the good firing cycles. This takes MORE fuel.
A smoking woodstove chimney is wasted HC fuel dollars, gone by-by forever up-in-smoke. Burn clean, efficient to burn the most fuel-use economical. All heat engines the same.
I will not be following the DOW overall anymore. I cannot support the mental distractions anymore.
Be posting up very little now. It is very difficult for me to language express out anymore.
I want to spend this last 3% of my life now setting up the wife and the family’s with systems they can operate and use without tech-no-freek me babysitting and trouble shooting.
Home here this will means a 15-16 hour IC engine system. Tri-fuel capable: gasoline, propane and woodgas. Cast iron bore Honda’s and Yamaha’s can do this 5840 hour annually easy once broken in properly with just then a $200-300. a year overhaul/restore. 2nd whole system the back-up/down-for-overhaul, suspenders. Cheaper to set up and maintain then a will-not-be-ever-looked-at battery bank.
John Deere tractor will get a new high capacity 31P battery. This will be the other 8 hours power source for lighting for nightlights and chicken lighting. 12vdc R19 base RV bulbs last forever with the best knocking about durability. What I used as an auto tech. Maybe even the new 12vdc LED’s
See in the cloud rain forest with lots of year around growing wood fuel, with NO reliable usable SOLAR, a BIG solar capable battery banks are not the way to go. I allowed myself to be diverted distracted there.
