A few years back for one of those storms I was unprepared, and didn’t have a generator so I had to rush to buy one. Ended up getting a champion 7850w. Didn’t need it for the storm but shortly after I bought a camper and used it to run the camper for a hunting season. Pulled it out yesterday, put some gas in it, couldn’t get it to crank. I ended up just setting up my small camper with my small generator on standby if we lose power. My main concern is losing all my deer meat and fish in my freezer if the power is out for too long.
Anyway, I’m really wanting a whole home natural gas generator so I don’t have these problems in the future. My house doesn’t have gas hooked up though. My street does, because my buddy down the road has one. Anybody on here had one installed on a house that doesn’t already have natural gas ran to it? How much more is that going to cost over having one installed on a house that already has gas ran to it?

Only trying to be helpful here…

If you would have done regular maintenance on this one it would probably crank fine. Whole house standby generators are no different.

If you spend the money on one, make sure to do at least quarterly and annual maintenance on it.

I agree 100%. Tinkering with things and doing regular maintenance is my worst enemy. Standby’s are set to run every so often though so if there’s a problem with it at least you’ll know ahead of time and can get someone out to service it. It’s not as much of a last minute “oh crap a storms coming, let me see if my pull start generator will crank” operation.
But yeah, I’m very much aware that I’m to blame for my generator not starting lol

That’s gonna be pretty expensive I’d imagine. Gotta call utility and some contractors for a real cost as the location and market will vary on price.

Prob cheaper to get one that runs on propane and get a 500 gallon tank.

But a couple backup carbs from Amazon, always need to drain fuel in generators before storing.

If your street has NG which you said it does I would budget at least 1500 to get a line run. The utility will usually do the meter free or minimum charge as long as the plumbing is to code.
Obviously the langer the run the more it will cost.

Better idea in my opinion.

I had natural gas run to my all electric house last year, or the year before maybe. The main was on the other side of the street. It costed me $500 for "construction" to run the line from the main, under the road, to the corner of my house. I believe it was around 50 feet total. The meter was free, albeit I get a nice $22 "service fee" on my bill every month.

Having natural gas service installed was a pretty long process due to Atmos having to line up a construction crew to dig and run the line, having a plumber come install the meter hook ups, then having Atmos install the meter.

You can probably get propane hooked up faster, but propane is also considerably more expensive than natural gas. My cousin has natural gas and had a 500 gallon propane tank installed solely for his portable generator. He never wants to go through having the gas shut off again

As an alternative, you might consider installing a solar panel with battery back up-system.
That’s what we did on our house. Bought the equipment from a well-known retailer out of Texas and installed it ourselves.
Would probably be a little more expensive upfront. But you get a 30% tax credit from the fed gov. And it pays for itself over time.

Also, the sun is free to everyone. So that eliminates any outside utility failures or them cutting you off for any reason.

Just run a cord to your freezer in house when not in the camper and don’t open freezer often.

Hospitals do not power the entire facility with backup generators, no home would need that much backup power. It'd ne VERY expensive to install and VERY expensive to properly maintain...and you only need about 30-50 amps at 240 volts instead of the 150 of the most likely 225 amp service your home has and could use at any given time. For instance do you need to run your washer and drier and you oven simultaneously while your AC is running and someone is taking a 45 minute shower? If the answer is no, and it is, you do not need to power your entire home.

The most practical way to have backup power...most affordable, safe and convenient, is to buy a 9000/7500 or so open frame inverter generator and run drop cords to things you can't live without. It'll cost you about $1500 or less and you can use it for other things. If you do not run any generator under a load for a pretty good amount of time each month none of them are going to crank when you need them.

I’m wanting to be able to run my 4 ton ac unit, a few lights, refrigerator, freezer, and hot water heater. About what size would be able to do that? A friend of mine works on equipment for a living and he’s convinced me to go the diesel generator route. He said his burns about 4 gallons a day, and people with natural gas generators have problems when everyone is running their generators at the same time. I’m considering buying a welding machine/generator that way it will get used more than once every couple years.

Except they automatically run periodically to prevent issues from long storage. This eliminates the lazy dumbasses that roll the generator out day before the hurricane.

If you plan on running your central AC unit on an open frame generator, you will probably need a soft start kit for your exterior AC unit. They are designed to reduce the starting current of the compressor thus allowing a “smaller” generator to power the AC. You also will need an interlock kit for safety and a transfer switch. Just google “running your AC with a portable generator “.
Genmax has a 10,500 watt tri-fuel generator with key fab start that would be a good option with natural gas.

Your buddy is correct. Every storm it seems like I hear of people who can’t run their nat gas generator because of low pressure on the system.
Also most of the units “genrac” are air cooled and not designed for continuous use as in 5-7 days and I know of several that have had issues with them with that continuous use.
If I was going to do a stand-alone I would do a diesel powered liquid cooled but section of my distribution panel to only power required items like (ac/freezers/lights)
I don’t know what size he has but 4 gallons a day seems very unrealistic and I would guess more like half to a gallon an hour for the whole house

43kw, so it probably doesn’t run much more than an idle lol

Be a man and get a 30kW diesel and be in control of your own fuel supply. You can get a good deal on a used model from one of the rental companies.

Definitely do not get an air cooled natural gas generator. If you must go natural gas, get a liquid cooled model, and get a giant propane tank and set up the carburetor for propane.

The other alternative is to buy the Chinese throw away gasoline inverter generators, and you can get two of them and parallel them for 60A at 240V which is plenty for most homes. They can even be set up to remote start from a transfer switch.

For me, it’s either use the cheap gasoline inverters or go straight to a diesel.

The main road by me has NG, but my little dead end street doesn't. So I contacted Atmos about how much it would cost to run 1500 feet from the road to my house.

They estimated $85k. I opted to buy a 500 gallon propane tank instead.

Also, renting large propane tanks is an option too.

Which cheap Chinese inverter generators can you parallel and get 60 amps and how do you do it?

Predator 9500s.

They sell everything to do it.

Harbor Freight Predator 9500

Get 2 of them. Install a transfer switch or at least a generator/main lockout for your panel with a 60A 2-pole breaker.

Wire the 60A breaker to a sub panel with 2 x 30A breakers and have each feed a weather protected box with a L14-30R twist lock receptacle.

Get enough 10/4 SOOW cord so that both generators will reach and put L14-30p plugs on both ends of each extension cord.

Don’t do anything stupid like electrocute yourself or burn your house down. Follow osha 1910 and NFPA 70E

ETA:
Forgot to mention to not synchronize those two generators out of phase… you’re liable to break something. Make sure all the breakers between the two inverters are closed before you start the second inverter. The second inverter will sense the bus voltage and will begin producing a sine wave that matches frequency, voltage, and phase angle.
