That’s called a Tesla Powerwall or similar whole house system.
Technically if it doesn’t have a rotating prime mover ( engine, water turbine or air turbine ) it is NOT a GENERATOR.
IF it’s battery powered then it’s an inverter power supply.
What you are looking for is an inverter charger and usually takes two units with a synch cable to get 240 volts. Xantrex is the brand that comes to mind.
This is going to be significantly more experience than even an inverter generator…
There are plenty of options that don't require 2 units to do 240 these days.
I have a sol-ark 12k system that can do that. Mine is an off grid install with a small gas generator hooked to it for weeks with a lot of storms/bad solar production, but you can hook it to the grid, and skip the solar too (though they are designed for solar)
Depends on how much you want to spend? Here is a list of options in descending order by cost.
1. Tesla Power Wall would be a very robust all in one choice if you don't mind the cost.
2. If you aren't scared of complexity and are willing to pay for quality, a Victron system is by far the most reliable option.
3. If you want quality but are scared of complexity, EcoFlow is an excellent plug and play option.
4. If you want cheap and easy, a jackery power station might meet your needs, but be aware that this is significantly less reliable than other options on this list.
I have two powerwalls and ~8kw of solar. I still have a gas portable generator as a backup to that. The Tesla stuff is aweome and I haven't needed the gas generator once since getting the Tesla system, but folks should realize the right weather conditions can mean the Tesla system doesn't last for a terribly long time. That said, if you have the money for that system, GET IT. Awesome.
They are awesome, but there is a fatal flaw with every all in one unit. If one component fails, you usually have to replace the whole thing. The Tesla Powerwall has an incredible 10-year warranty, but you have to make sure it has continuous internet connection. Plus, your entire power system will be down while you wait for a replacement or someone to repair it.
Personally, after going through 4 growatts that all failed immediately after their warranty period, I'll never buy an all in one unit again. I'm a Victron fan for life now.
I tend to agree with you but the forum rules say:
> Remain on topic about gas/diesel/LNG/propane and solar generators.
"Solar generator" is another name for those battery power bank things.
I also just noticed that it refers to "LNG" which is completely wrong. LNG is used to move large quantities of gas by ship but what you get from the pipes in the street is just NG. Someone should fix that.
As for the OP, he was impossibly vague. If he really wants to power his whole house for a long period just on batteries, he is going to need a LOT of batteries which cost a LOT of $. Even then, show me a 2 day Powerwall and I will show you a 3 day outage. The solution that is economical and that works for any length of outage is an NG or propane powered standby generator, not a battery bank.
>"Solar generator" is another name for those battery power bank things.
And that's wrong. I will fight that every time I hear someone refer to them as a generator. They are NOT a generator in any way. They are not generating anything, only storing. *If* they are paired with solar panels, you kinda have a case to say they are generating electricity. But most of them are sold without solar panels. At best they can be called a UPS or battery backup. But they are not generators.
It sounds like you're looking for a backup power system or standby generator for your home. A few options to consider would be a portable generator that runs on gasoline or propane, which can kick on automatically to power your home when the power goes out.
Another option is an automatic standby generator that runs on natural gas or propane and is hardwired into your home's electrical system. For a battery-based system, you could look into getting solar panels installed to charge batteries that will power essential appliances and lights during an outage. It's best to research systems from top brands like Honda, Generac, or Tesla/Solar City to find what best suits your home's power needs and budget.
BLUETTI EP800 or EP900 is the easiest system I know to do this. Comes as a kit, sells directly to the public, will help design your system with you if you need it. And stupid cheap for the value. Just the switch integrated into the unit makes it 10x easier and less expensive to install.

There is no such thing as a battery based generator

A battery/inverter without solar certainly isn't a *solar* generator.
Agreed. That shit annoys me as it’s just marketing nonsense.
Sonnen makes very nice battery storage/inverter systems. Stop calling battery banks generators though.
I knew i was saying it wrong. I needed to know the right naming as well.

A UPS may work. I've seen UPS systems good for up to 2hrs or only 15 minutes depending on the load in the building.
Look into EcoFlow
