Batteries won't need to be replaced in 5-10 years. Lithium iron phosphate batteries are good for 10 years of full discharge every single day.... And at that 10-year point, they still have 80% of their capacity left. So if you ran this every other day to near empty, and recharged to full, you'd get 20 years out of this battery and still have 80%.

The price of batteries is dropping about 5% every couple of months. If you're going to spend this much on a battery, much better to get solar first. You can DIY a nice solar system with portable generator back up for the same price and still get the 30% rebate. Unless something happens, the price of these will keep going lower and lower. Better to wait

Whole house generators are roughly $10-20k installed. They'll run for much longer. They will be louder.

This one qualifies for a 30% tax credit and will last 10 years

If youre not running AC, a house usually runs around 500W-1kW. Thats 24 to 12 hours with this battery, not accounting for efficiency loss. If you are running AC, then yeah, it would likely only last a few hours with this battery

I have a very tech-heavy house that generally idles around 700watts, but during an outage, I get that down to 300-400watts.

This would be nice for an "off the grid" cabin etc. I cannot imagine it will run everything in the house for long though, no?

I don't think anyone said they were "the same." Anyone making that claim, of said claim, is being disingenuous themselves.
Maybe actually investigate the series of replies to the original post before making such claims.

You absolutely cannot claim they are "the same" in any way, shape or form. Just because they solve the same problems doesn't mean they are the same. That's like saying a scooter is the same as an airplane. They both get you from point A to B so they're the same, right? Wrong.

Quote from ranova :
at 12kWh, this will likely keep a house powered for 1-2 days without solar depending on usage. If you get the panel for an extra $1000, it will integrate nicely into the house. If you have a full-blown solar system on your house, and its sunny, your house likely could be fully powered indefinitely with it

Im not sure how its not "the same" as a gas generator, at this size. If you run out of juice, then yeah, its dead until you can charge it up again. The battery backup systems that are 1-2kWh are not considered whole-house backup generators since you couldn't really power much. Reading specs, this has a 7200watt output, which is more than the Powerwall 2 at 5kW max output

In other words, its the same as a gas generator as much as an EV is the same as a gas car.
I agree with your final analogy (more or less). Two different ways to get the same result, but they don't both cover all use cases. For example, you probably aren't going to take an EV off road or as an Antarctic expedition vehicle.

12kWh is not that much power unless you cut your usage significantly. My home uses over 30kWh per day. 7200W output may run a window AC unit or a small mini split, but it isn't going to run a central AC unit. You are right that full sun means more or less unlimited power (assuming your consumption goes down significantly at night), but a whole home gas generator user can also claim that as long as they have an active NG supply they can run indefinitely (100% of the time). Neither is really true; both sources of fuel can be compromised in an incident, and both can suffer from failure.

The thing is, if you have $50k of income to throw away on this problem then of course the way to go is a whole home battery system. Get yourself a nice 15kW inverter setup with 30kWh+ of battery and sufficient paneling to keep it topped off and you will have a kick ass system that is going to be more robust than a generator. But I can take $10k and get myself a top of the line NG whole home generator, so which is better? It's very subjective.

I personally choose to use smaller, portable batteries to keep key items in my house running in short outages; I have Ecoflow Delta 2s that can power my furnace and fridge, some River 2s to power utility items, and a few custom batteries for misc other power needs. When an outage is no longer short, I roll out the 11kW tri-fuel gas generator and do a whole home hookup with a GenerLink; it is powerful enough to power my whole home minus 240V appliance (and those can be run if I shut down a sufficient number of other power consuming devices); it can even handle my central AC unit thanks to a soft start kit.

Would be nice if it was cost effective to have this utilized in a non-solar home for peak hours usage and recharge overnight at lower rates. But, even with the 30% tax credit and living in an area with obscene peak hour rates (@34 cents/kwh here), it probably doesn't pencil out.
I envy you. That's our off-peak rate here in the SF Bay area

I hear you. We have ~44 cents/kwh here in MA with no off-peak rates. My rooftop solar went from ~7-8 year payback to 4-5 years after rate hikes in the last couple years. Still looking for a battery, though, to potentially cut the utility completely out.

Except there is a ton of circuitry that can go bad and it's hard to find anyone nowadays that can fix it.

Here's a thing... this $7,000 product stores 12kWh of energy. At U.S. average residential rates, that's just a tad over $2 worth of electricity.

It's like storing your rice in solid gold containers.
No clue how you came up with this... but my per kwh rate is 13.8 cents.

So 12000x.138= 162 dollars

If this was able to self charge itself I could use it for the entire day and save 250 month in utility cost.

I replied to a single comment, not someone's life history nor everyone they have interacted with during said existence. Maybe understand not everyone is a dedicated to useless debates as yourself?

SECOND TIME. I never nor the person I replied to made that claim. Now, could their ex-neighbor's hair dresser's 3rd grade teacher have made the claim in 2003...perhaps? I'm sure you'll let is know if that conversation occurred.

Now, the outcome is the same. Both provide power. For someone without power that is probably the most important detail. Not how the electrons are forced upon their path. Your fridge nor HVAC really cares about that either.

Wow, you are just inserting words in my month so you can later contradict the argument you just accused me...using absurd analogies? LOL...you win.

BTW, it would be like saying a train is similar to a monorail. There are some functional differences in how they operate but the overall theory, infrastructure, and outcome is comparable for the end user. Much like comparing two different power delivery devices Wink

Bye bye

Quote from KevoD :
In non-flyover states, it costs anywhere from 50 to 70 cents per kw during peak hours. So that's about $8 of energy based on today's rates. It's only going to get more expensive with each passing year. For CA homeowners that regularly use 12 kWh during peak hours, this would pay for itself in about 3 years when considering the TOU delta between peak and off peak hours.
lol, no it doesn't... Not yet at least. - I pay 12 cents per KWH... If EVs ever being a serious thing (unlikely), it will be that expensive but not until them, when the power companies are seriously trying to dissuade people from using electricity to control demand/when the government starts taxing it like crazy to make up for lost fuel tax revenue

You all still wanna make jokes about FPL not giving away "free" thermostats? Sounds like those free thermostats cost you 40 cents per kwh lol.

Gens 1-3 do. The Gen4 Prius uses Lithium Ion batteries - except for the AWD version, which uses NiMH. Gen5 is all Li-ion.

You multiplied watt hours against a kWh rate.

It should only be 12 x .138

Yeah….your math is just a tad off.
