You're absolutely right, getting power from your power company is far cheaper. But when the power company stops sending it (for whatever reason), this ecoflow instantly becomes cheap insurance.

What makes these discussions fun is that each of us has a different idea for what a "power outage" might mean. After a hurricane, a day or two. An ice storm on the top of a remote mountain, maybe a week, a complete grid down scenario from ransomware, terrorism, etc..., this ecoflow and some solar panels suddenly becomes priceless.

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.

This looks so tempting. I just dont know if I can get this to work for my setup.

I would love to get some advice if anyone feels up to some knowledge share.

I have 39 solar panels with enphase inverters that is grid tied to my current 200amp panel.
I was thinking of setting up this panel 2 with essential breakers like fridge, well pump, water system etc and then have the delta pro ultra be a backup or UPS for the subpanel. I have frequent electricity drops (2-5 seconds, sometimes several minutes).
I also wanted to know if this would either be grid charged or solar charged or even generator.

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.

Fuel generators convert the stored energy in a liquid to electricity. Battery generators convert the energy stored chemically in the battery to electricity.

This kit comes really close to the cheapest DIY kit from EG4. A EG4 6000XP and a PowerPro (14.3kwh) is around $5,300.
This will be easier to plug and play, and does not require a permit.
The smart panel 2 really sweeten the deal for an additional $1K. The Span smart panel is $3500.
If only I had $8K to spend on this. Very tempting.

That's a horrifically flawed way to view stored energy. Perhaps more useful for one-time use batteries like a pack of Energizer AA, but I'm struggling to think of a more bad faith way to think about the value of stored energy let alone one that can be continuously reused such as rechargable batteries.

It's one perfectly valid context to consider. I never claimed it was the only one.

But there is a take home lesson: the storage of electricity is really, really expensive. Something to think about given the proposed solution to climate change is based on weather dependent renewables with storage backup.

I have two Tesla Powerwalls and I'm very happy with them and the concept of backup batteries. We've had a couple power outages and the batteries immediately kick in and prevent anything from shutting off. The PWs are charged by the solar panels and run the house during peak TOU rates. Each year my utility owes me money due the PWs. If this system is anything like PWs then you should be very happy with it.

I wonder about that. In theory, all home-backup batteries need to be UL9540 listed (in about 40/50 states). This doesn't seem to have that rating. I'm not sure if it's because most people are using it without permits, but to be 100% legit, I don't think you could actually permit this thing.

From my understanding this is just a ton of AA sized batteries linked together.

What happens if one of the individual batteries goes bad? Does the whole bank fail?

I bought the river pro when it was a kickstarter. Barely used its, it was for emergencies. It broke with under 5 use cycles. They replaced it And I used that as a UPS and that broke too with under 5 power cycles. I can't imagine spending $7000 on an Ecoflow product.

You realize the device you use to get online and comment also has a battery and is using electricity? Sorry to inform but you're right here in the matrix with us 😉

This is kind of tempting.....cheaper then a Tesla Powerwall. Will have to do a side by side comparison.

That was my exact same thought. Hopefully someone here will shed more light on this. How long to charge and how. How durable. How to discharge into system? I may have to stick with powerwalls as I write.

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.

Please math it anyway so us less mathy people can see the numbers 🙏

I also have powerwalls. The possible problem I see with this (for some people) is if you don't have solar panels, how will they charge the batteries? From the grid I guess. We're in a good position where we can use batteries overnight, then charge them back up again the following day with the panels. I'm also very happy with the Tesla setup.
