I got this last time (without the panel) and am overall reasonably pleased with it, though the promised trolley still hasn't arrived. I do recommend strongly you have a plan to integrate it with your house before you buy it. I am stuck trying to integrate it since I have an older house and panel with limited options to hook up a essential load panel and so on.

In retrospect, I might have chosen to go down a different path now that I know all of this, and am still debating returning it and replacing it with a DIY solar PV system, but it's not for the lack of quality but logistics for my particular house, and what I'm trying to achieve with it. Otherwise, it's an extraordinary device.

I got the 12 kWh version and overall I am pretty pleased with it but there are some issues.

I tried using the 0 ms online UPS port to power my network & server stack directly, removing my normal UPS from the path, and few days later got a notice that the NAS had unexpectedly rebooted. Looked and found that the entire network & server stack had unexpectedly rebooted, meaning that the online UPS port briefly went offline for some reason. I've split the load across the online & standby ports to see if it happens again and so far it hasn't, so I don't know what caused it to happen. It might be load related, might be linked to the fact I was only using an online port & not the standby ports, or it might have been a one time thing due to some combination of those.

The other annoying point is that the scheduling for time of use/time shifting is half baked at best. It is only possible to create a single schedule, which doesn't sound bad but is extremely frustrating if you want to have different schedules on different days. In my case I need a M-F schedule, the days I have mixed on peak/off peak power rates, and then a Sat-Sun schedule when the entire day is off peak. That simply isn't possible to do. Creating the M-F schedule entry works, but then it is impossible to add another entry for Sat-Sun. With just the M-F schedule the system shifts to battery only mode on Saturday and only pulls from the AC input when the battery is drained to the configured minimum level. To make M-F work, and still have it use the AC input most of the time on Sat-Sun, I had to create a single entry that says I have a peak power charge every day. So even on the two days where I don't need to power shift I have to because I want to power shift the five other days.

Oh, and setting up as "time of use" had its own problems of running on battery even though the app dashboard said it was supposed to be charging the battery. Supposedly there was a bug about it using UTC instead of the local time zone, but I'm not sure that was what was happening. It might have been because when I finally left it alone for a day or so it did seem to finally sync up with what the dashboard said should be happening. At least mostly, since the same single schedule problem above exists and it still went into battery only mode.

Have you joined the EcoFlow DELTA Series Official facebook group?

Regarding hookup, I figure you can just install a standard transfer switch with interlock or a GenerLink. That would be the best way without the SHP2.

The Smart Home Panel 2 has some potential issues. If there's a problem with the relays, they're integrated, so you'd have to replace the entire panel. If you use a transfer switch with interlock, you can power everything (your main panel) through your Delta Pro Ultra and then connect the DPU to your service panel.

San Diego. Thanks to SDGE
Ah hello neighbor I went to UCSD for undergrad. Those rates make sense now lol. Well I'll tell you this with your rates I would absolutely be looking into a power station even if i didnt have an electric car. Not sure I would use the Ecoflow breaker panel though as I've read enough people having issues with those. Even if its using long extension cords to various power hungry appliances (my preferred way) I would save a lot of money at those rates. Best of luck to you.

Except your generator is subject to shortages, extreme price fluctuations, and delivery issues.

A decent standby generator still costs about $7000 for the unit and doesn't offer nearly as many installation options as a battery unit.

The reality is that in 10 years, these batteries are only going to get cheaper, while your generator won't.

Ideally, you'd run both instead of pitting one against the other.

Probably a stupid question but this would be eligible for the 30% rebate if installed as a whole home battery, correct? Just dipping my toes into this territory as I'm sick of massive energy bills due to Time of Use plans and a family that does not understand Time of Use plans. If I could switch to battery daily for three hours and can expect a 30% rebate, napkin math says ROI is under three years for me, which would be worth it.

I don't recall the specific kWh when the answer becomes yes but at 18kWh I feel pretty confident saying heck ya this would...

2 sec Google search shows that it must exceed 3kWh!

I looked at the Costco 12kWh price and this 18kWh and with the $ off don't know why many would go for the 12kWh. That said the 6kWh would be the most useful for me with our TOU rates but the problem is all the costs it takes to hook it up unless you're good with all that... Am definitely happy to see the prices come down on these as Tesla just seems to keep on raising theirs while we all know batteries have come down in price a lot over the past several years!!

You won't be replacing these in 11 years.

Lifespan of 10 years is not the same as it stops working and you have to replace in 10 years. For LiFePo4 batteries it means that after 3500 charge cycles, the batteries will be down to 80% charge capacity at most. So for this deal, at worst, you'll only have 14.4kWh of battery capacity. That is still more than enough for the average household for emergency use.

Do you replace your generator at the end of it's warranty? How about your car or appliances? You cell phone or computer? If not, why would you think that this needs to be replaced once the warranty or lifecycle ends?

Do you run your gas generator 24/7 like this is designed to do? If so, how much is the fuel cost to run it 24/7 over 10 years? Enough to replace the batteries on this unit several times over I would think. If you ran your generator 24/7, do you think you wouldn't need any type of maintenance on it? Oil changes? Engine rebuilds? Fines due to constant noise complaints from nearby neighbors?

What happens during a catastrophe when diesel/propane is not available? It's less likely that we lose access to the sun than we are to have no access to diesel/gas/propane. Before you try to say how about when it rains/snows, I have solar panels on my roof and even during that last two years of heavy (for SoCal) rains, I never had a single day where I did not produce at least 10kWh of AC generated. That 10kWh only occurred once.

I have cheap power from 12AM-6AM. At 12c/ kwh This is when I charge my electric car. Can I back up (fill up) this 18 kWh every night and use it during the day. For context my non- peak charge is 45c and peak is 65c.
You spent how much to save how much everyday?

Dang where do you live? Those rates are nuts lol. My peak rate is 16 cents lol my off peak is 7.
This is typical for southern california. Very similar to SDGE rates. the Deltas in TOU prices are insane, so there is a really quick payback time.

Do the math, the daily payback assuming 90% round trip efficiency is $8.58. Multiply that by 300 (~80% utilization) gives $2575 per year. This can account for the fact that winter rates do drop a bit. This gives a 2.71 year payback time. Even if assuming lower utilization, a very conservative estimate would be within 4-5 years.

Not bad considering the ROI of other home projects is typically in the 5-10 year window

By using the DPU during the day and recharging it at night, he saves $9.54/day if he used the full 18kWh capacity. Assuming he spent $11,900 to purchase and install it, he would make back his money in a little less than 2 years and 5 months. That's assuming electricity costs remain the same (which it never does, it only goes up).

Your way of thinking is a bit short sighted. Also, not everything is about ROI. Ask the victims of natural disasters how much they would be willing to spend to not have had to live without electricity in sweltering heat and humidity or frigid nights for weeks at a time. Forget about creature comforts like temperature control. What if you or a family member have life sustaining medical equipment that needs electricity to function?
