Especially the big ones. And I mean really big. Like a 500kw, 480V rated generator powered by a monster V12 2-stroke Detroit Diesel engine, with 4 big ass turbos, feeding 2 big ass superchargers, feeding the engine. Things fuckin scream. If youre not familiar with 2 stroke diesels, they can be scary. Sounds like a runaway diesel engine but its just how they sound. They have a terrifying amount of torque. I like to joke that these things could probably twist an F250 into a pretzel.
Or a monster 90-Liter V16 CAT diesel engine spinning a generator rated at 2,000kw 480V. Just doing an oil change on those takes forever. They can hold like 150 gallons of motor oil and have like 8 oil filters that hold a gallon of oil each and stuff. Just running the engine with no load on it, theyll drink up like 150 gallons of diesel an hour. Crazy.
Fun fact, 2 stroke diesels only have exhaust valves, and can not run without a supercharger by design.
I think solar is a fuckin joke. Those panels dont make shit for power. U gotta have a lot of them. Not worth the initial cost if you ask me. Plus it has to be sunny. Generators dont give a fuck if it's cloudy. Plus if u really want backup power, why not just skip the solar bullshit and keep a bunch of batteries charged, and get an inverter to convert it to AC.
Hell yeah they are. I have a couple 1200W inverters. Very handy for when theres no power outlet available. Just hook it up to my truck battery and bam I have a couple AC outlets
If batteries are the heart of your system you have lots of problems anyway. Unfortunately the batteries are the most expensive, most complex, and most maintenance intensive part. Solar is a better match for charging batteries at the C/8 rate (8 hours to fill, 4 hours from half charge) which is best way for a flooded lead acid battery. A charge cycle will have the generator running for 4 hours whenever the batteries hit half-charge, and you still need inverters and all the other crap. If batteries are going to be your main power source then solar is actually a really good option, geography permitting. Having big batteries and inverters allows you to right-size the generator to some extent down towards average load, and that's good. And you'd want this anyway because you really can't repeatedly charge batteries too fast.
I used to run solar in an RV. I lived off of it. I know how to design a solar system and the first rule of that is to take what you need and then at the very least double it. A system that has panels, batteries, and a generator might actually come in the cheapest because you could actually right-size everything and run the generator very rarely and shoot for a 20 year TBO on runtime. You'd use less fuel, fewer panels, and fewer batteries, and you'd have much more redundancy. tldr; solar is good.
Not sure if you are joking, but from what i can tell they are just lithium batteries with inverters and charging circuitry. So they can be hooked up to a panel and used that way, and that is how they get away with calling it a "generator".
No I wasn't joking. The sales pitch is sleek but something seemed fucky. I already knew it wasn't what I needed. But the attraction to it was gas wasn't needed.
Some guy on here posted about Amish people and how they do ,so Ive forgotten about those generators and have been interested in a propane fridge.
A solar generator, I'm talking the ones on a hand cart with a few panels, aren't in the same league as a gas generator. Expensive novelty is correct. I suppose if shtf in the future and there was no gas, you could at least power a radio or charge your laser gun.
No, it's not that at all. You could just build a radio that requires no power if that was at all relevant to the topic, which it isn't. These things are limited by a dippy inverter and by small battery capacity. Even 1kw isn't that much battery for running anything important for very long. It's not a replacement for a proper generator that can run a space heater, window AC, or anything like that. These are for lights and keeping shit charged. It's an expensive novelty.

Like any two stroke, they have ports in the cylinder wall that are uncovered as the piston nears the end of its stroke. Air is pushed in through these, under pressure from the crankcase or the turbo/supercharger. Technically don't need an exhaust valve as ports will serve to allow the exhaust to escape as well.
In the opening scene from this video every vent you see in the building (and each exhaust pipe) is a 1MW generator. It is an absolutely insane setup, but i guess they need to be on all the time. It is near Offutt air force base, is fed by 2 power plants, has 3 generators per section with a 4th ready to replace any of the 3 if there is an issue.
U usually use a 12v pump and a few empty oil drums. While waiting for the oil to drain ill go ahead and do that oil filters. The canister/spin ons usually hold about a gallon of oil each. Cartridge type filters are usually easier. The tricky part is that sometimes theres not much room to fit an oil pan or bucket under them to catch the oil that will pour out once u remove a filter. Cant be making a big mess on customers' units.

That can work but a dedicated truck is just easier. Just depends on how that skid is set up and who packaged it but i usually zip tie a bucket underneath and use my flexible funnel. Letting that drain back go for a good while while you're doing other stuff. On the bigger engines like the 3600 you've gotta use that drain back or its gonna make a huge mess. If it's not tied in properly sometimes if I have extra tubing I'll go ahead and just make a drain back line just to save that mess.

I don't trust them. I've looked at two of them and I'm thinking they are an expensive novelty.

Not really but it does take a medium duty pump truck. Oil filters aren't too hard either , both the canister style and spin on.
3 if the canister style not sure about the spin on but the housing does hold like 3 or 4 gallons
