Nice of you to say my fuel numbers are flawed, when you can't actually point out what's flawed about them. My fuel flow line sorta maxes out at a little over a gallon an hour, but I can't get my generator to consume much less than half a gallon an hour, either. While power output can be from 0kW usable to just over 4.5kW usable in that range.

Your fuel number are the same when powering your house as they are when powering the house and recharging your battery?

Hard to believe, if indeed they are, then I apologize.

In that it would probably be 20 gallons a day vs 24? Is that what you're complaining about?

An idling generator still uses gas. The recharge cycle of the batteries allows the generator to run at its most efficient load.

And we already covered that we don't use that much power. Much of our lighting has been converted to low-voltage LED, etc.

Give me the details, gallons per hour at different load levels.

How many gas cans do you have? In case you don't know, in an emergency (or even threat of one), gas cans and generators are the first to go out of stock.

Dude. Give it up.

I literally do not have the equipment that can count flow rates that are between 1/2 and 1 1/2 gallons per hour. So I only have an estimate of my consumption. I usually use 5 gallons in between 4-6 hours, going by when I have had to use a grab-and-go tank because that's all that was available (I always keep one around just in case).

And yeah, I have had to - because I can't always get refueled, unlike your claim.

For yours, I didn't know the fuel so I looked up diesel consumption estimation from generator installers.

You've moved the goalposts so many times to say 'Powerwall, Power Share useless!' I don't even know what you think you're proving.

FYI, there are these things called specifications. Most generators, except for knockoffs will specify their consumption.

Specifications are kinda useless if you're not using it for exactly the spec.

You're the one that said you could generate 60kW for 'weeks'. Then you contradicted that.

No, specs are not useless. Generator specs are usually given at different load levels so that you can make the comparison. And most importantly, If it says 10g/hr at full load, then you are pretty well sure that it is NOT going to be 1g/hr or 100g/hr.

And no, I didn't contradict myself. But you are just too blind to see that at this point, batteries have very limited amounts of power that they can provide, especially over extended times.

If during a winter cold spell, where it is overcast and really cold, below 0 cold, my heat pump is going to add aux heat and I wouldn't be surprised if I'm pulling over 40A @240V for over 12 hours.
That's nearly 100 kWH per night.

Just looking at the EcoFlow DELTA Pro Ultra, while it will handle the 10kW, it maxes out at 90kWh capacity.
-Up to 90kWh capacity with 3 inverters and 15 batteries
i.e. may not last me through the night, and no solar augmentation.

My generator gets me there.

Dude, 'limited' use: Most blackout are under 6 hours in length in the US. Which means my batteries keep my stuff humming along without touching the generator unless the power has been out eight to twenty four hours (depending upon what mode I'm in.)

That's also the same amount of time you'd need to time-shift prime-time usage.

So no, batteries are not at all of limited use: They're more useful than generators.

On top of that, as has been pointed out, they make generators far more efficient because you won't need to idle the generator when you're not pulling that large of a load. Which is most of the time.

Someone has to say it, imo the whole powershare in the US is a load of ? ?.

Going back decades, i can count on 1 hand when i lit a candle because the lights were out. Im not going to hack/complicate my house's electrical system. Forget about actually paying for it.

That's San Diego Gas and Electric, they aren't even the only utility in San Diego.

PG&E rarely gives us planned outages unless something in our neighborhood is being replaced. Can hardly complain about getting a new pole, can we?

Dude, I don't plan for "most" blackouts.

I can absolutely guarantee you that unless I specifically turn off a LOT of stuff, my generator will never "idle"

Why can't you accept that you and your house doesn't represent EVERY other house in the nation?

Do you think that these houses can run on batteries?

Yes, yes they can.

Why do you think they represent typical houses, or can't run on batteries?

Seems like you've run pretty far afield to support you 'batteries are of limited use'.

So give me some example systems that can do it.

You can assume that the houses have at least dual 400A panels.
And the houses are over 15,000 sqft.

The pools on the second picture are probably on their own 200A sub-panel and are pulling 10 kW during the summer and another 20kW to warm in the winter. And yes, when you can afford this price house, that pool better be available 24x7.
I'd also expect a major family kitchen, 2 secondary kitchens, and a commercial kitchen.
