I know this is still wildly expensive but the same 2 battery configuration on Ecoflow's website is $8798.

If you're in the market for one of these this price for 12kwh can't be beat.

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

The biggest problem is reliability and warranty. If it breaks in 2 or 3 years, the investment does not make sense at all.

Quote from Pythonz :
I think the idea is that this would be integrated with a solar panel install, so you would be continuing to recharge it during the day. They also have a smart home panel, which is basically a sub panel that can kick on in 20ms in the event of a power outage, so there is the option for seamless transfer. Also factor in a 30% rebate on all this. Not saying it's not expensive, but I'm not sure it's as bad as you're making it out to be.

Smart panel = transfer switch. How many people have such a thing?

What I am saying is, if this is intended basically to be backup power, you also have to cost in all the stuff you'd otherwise be using for an alternative. Yes I guess you could plug this int a dryer outlet (like you would a generator) but it weighs like 100 lb. Not exactly carrying it around.

So realistically you're either getting a transfer switch (for real time switch over), or you're doing a manual interlock. Swapping out a panel for a smart panel is going to be very pricey, probably more than the transfer switch to be honest.

We all know that most toyota cars will last 10+ yrs if properly used and maintained but toyota only give 2-5 yr warranty.

Not just toyota but your iPhone only has 1 yr warranty but we know it will last longer than that.

Your comment is funny.
yes, but we all don't know the real life of these batteries yet.

Does anyone know if I could configure this to automatically kick on at a certain time each day? Our electrical rate almost triples from 4-8p every day. This might be worth grabbing if I could have it charge overnight and then replace our electrical usage each day from 4-8

Quote from jaysen :
Anyone with knowledge/experience, specifically in California, please chime in: I currently have Solar that was installed back in 2020 - took advantage of Fed Tax Credit then.

I opt'd not to get power walls just because I did not see the point/advantage. Although my circumstances have mostly gone the same since installing I definitely see more benefits of having a power wall for off-peak usage. I generate a lot of excess electricity that feeds back to SCE for pennies 😡

If I were to buy something like this, can I:

1) Take advantage of the tax credit again?

2) Set this up so it recharges during daylight/solar production and have it automatically kick on once sundown hits.

3) assuming two is possible, is it a seamless, no moving parts kind of deal/setup? Or will I have to manually hit switches or remember to enable/disable something.
Wasn't it one for one credit for NEM 2.0 ?

I was close to getting this system (and SHP2) about a month or so ago, until I saw on Reddit how many issues that people were having. Some had paid for full installation, only for their sub panel to go out within days, which would require a full replacement. Imagine having to pay for installation multiple times because of bad QC on the manufacturers end.

Get a used Prius instead, then you get a 2fer car plus emergency house generator

The same? One has a fixed capacity but can be charged with solar, the other has an "unlimited" capacity as long as your fuel doesn't run out.
Not to metion all the maintenance of an internal combustion engine. Slack off on the maintenance and that gas generator may not be there for you when you need it.

The battery "generator" requires much less maintenance and can be used in spaces where CO would be a problem. Townhomes come to mind.

Quote from SlickHorn646 :
Charging another car is nice if someone is in a pinch. But I thought we talking about home backup?
Initially he was saying that if you have an EV (specifically a Polestar iirc?), you already have much larger battery backup (+ a fun car). Someone else said that only the F150 has bi-directional charging to a home. This guy is saying they can "turn it on" someday. So... home backup adjacent.

This will run my entire house? Is this portable in the sense I can charge it at a free electric car charging station when its running low?
I don't think any of these kinds of batteries have J1772 charging ports.

Also... the battery isn't that big. That's a lot of hassle for a couple bucks worth of electricity (Plus, you'd have to stay with the car/battery instead of like... going shopping. Since this wouldn't plug into the outside of your car).

My neighbor got a whole house generator. Runs a few minutes each week. They've had it for 15 years, when the last power outage happened during this last hurricane. It didn't work and they were told they need a new one. Unless you live in a place that gets frequent power outages, just live without power for a day, no biggie. In Florida, hurricane big enough to kill power are really only every 10 years and not often enough to buy one.

Since CA rate for electricity bill keeps rising, do you think it makes sense to install this device. Everyday I use grid power to charge the battery at night (lower rate) and use battery to power house daytime?
If my avg. monthly bill is 300$, roughly how long can break even?

The Hyundai Ioniq line has bidirectional charging, but I haven't seen anything about home backup integration. I hope they'll come out with something at some point. Tesla doesn't seem to have any interest in it for some reason. Maybe they just don't want to cannibalize their powerwall business.
Cybertruck has it.

Quote from CyanCorn8418 :
The other thing that's funny is that while the calculations and all make sense here, it still winds up costing way more than that with all the overhead charges.

So this sort of thing really only makes sense if you can really disconnect from grid and utilize your own power generation, otherwise you're really not saving money unless you really do know how to utilize "off-peak" electricity arrangements and it still works out. Or you actually really just want to have a hyper backup of energy in case of an emergency, at that point that's up to you... I can get by on much smaller or nothing.

I'm basing this off my last electricity bill -

450 Kwh = $90

90/450 = $0.20 per kwh after overhead

After looking at this, it really doesn't make sense to have this for anything outside of some real emergency use scenarios...
Honestly, just enough to power the fridge for a week and maybe internet essentials, assuming the internet company still has power running through their lines as well. With a couple portable 400w solar panels, you'll be good imo.

Where you are, 20c per kwh is a great price. It doesn't make sense for you. But for people that are getting screwed 3 times over at 40c per kwh and high price of gas, it becomes much more feasible.
