“Yes, they can run for a short time on batteries but with no shore power for a short time there is no way to charge.”

In 2020 you claim there is “no way to charge?” S-O-L-A-R.

Loaned my 3600W generator to friends who had a major power outage during an ice storm. Ran on their covered front porch 24/7 except to fuel and check oil for 14 days.
I suspect as long as you keep good oil in it it would run just fine for months on end at 7KW it will not be loaded and running hard. They are loud and if any distance to keep noise down be sure and run large enough power line.
It will not be cheap figure 1 to 2 gal per hour depending on load.

I agree. It was designed to run and if properly maintained and serviced is will run until it wears out.

Big old open frame construction generators are very noisy, and will burn a lot of fuel since they run a full speed regardless of the load.

If I were doing something similar, I'd get a Honda EU7000, or a used EU6500.

I have an EU6500 and love it. I found it used on Craigslist.

Really appreciate all the feedback. I was looking for real world info, not just the brochure info, and I got what I asked for.

Very much appreciated... This is exactly what these forums are for. Real world info...

I would say really need to reconsider the whole mindset...

The only reason for a gen is to run Air Conditioner. You said SW, I think... nights will be cool? Away in the day?

For just a few days you can do whatever, but for extended time (weeks or more) you need SOLAR.

You can run a trailer of DC power, thats battery. You can keep the batteries charged on solar. Usually 200 watts is enough for 2 batteries and light use. If you want TV and laptops and all the lights on then maybe 300 watts and more than 2 batteries. You will need to calculate your amp hour needs and divide by two as you never want to run batteries dead, half-dead is not as bad.

For a stationary trailer you can put the solar on the ground and aim them/ angle them towards the morning sun, or evening sun depending when you will use the most electricity, or move them as needed.

For AC you need a generator (or a cost=prohibitively large bank of batteries). Get the smallest that will run the generator. usually 3500 models will do it.

If no AC then go solar.

If solar, get deep cycle golf cart batteries, or other similar deep cycle. Don't bother with the "marine" batteries that are half car half deep cycle. You want a real deep-cycle. Deep cycle batts will last longer and be able to be discharged many times more than a marine, meaning they won't die.

You will need a charge controller to go between the solar panel and the batteries. Get an MPPT controller (not pwm). They will be expensive compared to the cheap china ones, but really $80-$150 or so is not bad for what you are doing.

Get Mono crystaline panels. Not the flexible ones. The poly are maybe a little cheaper but the mono is better.

I can't imagine trying to run a giant inefficient generator all the time just to have power for the water pump or one light bulb or to charge a phone. What you will save on gas and oil (and price of gen) will pay for a solar system, and your hands wont smell like gas all the time.

These are the only posts that know what their talking about.
And to ad to that, it will wear out after many more hours running continuously, than being shut down every day.`
Having said that, running a genset continuously for the OP's use, is about as ridiculous as as one can get.

I will say again: the max run time on a generator is determined by the size and location of the fuel tank. If you have a big enough tank. or a remote tank (propane generators or Natural gas qualify here) or a Honda with the Extended run tank.

Weeks on end (With the E/R tank you run till it's empty or near empty. Unhook it an let the genny run with the on board. Remove tank to refill then re-connect.

NOTE: this is not a recommended procedure and those generators are not really big enough for whole house use

But the basic limit is the gas tank.

My Motor Home's ONAN has done several 26 HR runs


Home is where I park it.
