Tech Tip: Megawatt / Tiny Generator

Number uno el mas importante...

I think noise level is the bottom of the list here
I think fuel efficiency for ampHrs is the top of the list
As priority one

Hairpin alt -

75 amps at 1,500 alternator rotor RPM

To be coupled to an inverter to power Jesús' freezers at the enramada.He now has 200+ Kg of lobster stored in them. And maybe another 200 Kg of red snapper. I have an unused old Trace 1500 watt (white) 12-volt inverter. He can use the battery out of his boat as a ballast.

Honda makes a consumer grade engine and an industrial grade engine (black). The price of a 5 HP industrial is a real knee-knocker.

David ... I guess you'd have to use a purpose-built box in order to get a free standing Honda engine down to, say, 47-53 dB at (whatever high) RPM?

(... or is noise the least of your worries?)

I've got some kind of phobia about letting a generator lean on a shovel. The phobia is aggravated at gas stations watching $$$ numbers pass in a blur as containers are filled. The pack-your-lunch trip to from the gas station doesn't help either.

I'm roughly doing the same thing when our RV's 230 AH AGM battery bank is down around 50% and I:

1) Start up my 600 watt Honda generator with the main motorhome power cable plugged into it.

2) Then note that the ~13.8 volt built-in stock 45 amp Parallax converter is dumping 10-12 amps into the battery bank.

3) Then plug in my 10A/50A Sears charging-starting battery charger into the generator via an extension cord.

4) Then switch the Sears charger-starter unit to it's 50 amp engine-start mode to increase the total charging voltage on the battery bank.

5) Then note that the charging voltage on the battery bank is raised a little higher than 13.8 volts and that the two sources in combination are supplying 15-17 amps into the battery bank.

The Honda keeps right on running without any problems. This is a "non-adjustable and less efficient" way to use a small (and very quiet - in my case) generator to do what Mex is doing better with an infinitely variable power supply fed by a small generator that is kept loaded manually just below it's circuit-breaker trip point.

Mexican't almost gasolina....

I showed Hector, how to bubble his battery cells once every two weeks. The cheese is queso de rancho de chiva. Hector, is regionally very famous for the cheese he produces. Some folks drive 200-miles to get some and there is a long long line waiting. Some goat cheese is strong enough to lift a chassis. Not his. Very similar to German Schloss. Outrageous sprinkled over salad or frijoles de olla. And yaint tasted beans until you taste this-year's-crop beans, cooked in a clay pot over a smouldering mesquite fire.

The generator is red in color with a black PLASIC! fuel tank but no brand name. It has a single right angle lifting tube with bicycle handlebar grip.

Guess I don't understand what's going on here. My little HF 2 stroke generator will power my 40 amp charger to a full 40 amps with no problem. Could the little generator be constipated? Carbon does build up in the exhaust port over time and needs to be cleaned out once in a while.

I have a voltage potentiometer on my dashboard. With a depleted battery, and a cold damp drive belt on a rainy day, I can get belt to stop squealing by lowering voltage, or knwinng it will squeal, start with a low target and dial it up until it does begin to squeal.

Same concept.

Voltage adjustment potentiometers are awesome

Cotija, Oaxaca, Queso? Make mine extra sharp cheddar. ;)
Every day is a camp out down there.
