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.

I just set up a 3KW solar array and am currently running an Ecoflow Delta 2 Max and Anker F2000 off them. It's costing me 53 cents off peak and 66 cents peak under greedy PG&E. I am planning to expand to a Delta Pro Ultra or something similar once I get more money in the future. It's going to save me money especially since PG&E wants to keep increasing rates while making billions in profit.

I got sce and those are about the same rates I have. Its a scam I tell ya, especially when the neighboring ladwp is like 26 cents peak (maybe less).

Yeah, PG&E killed a bunch of people with the wildfires they started, and they made the rate payers pay for the damages and lawsuits. They have a complete monopoly in my area. While 10 miles away in another city, they're only paying 17 cents per kwh. Might as well invest in having a power supply that won't be affected by blackouts and pay less money to the greedy CEO who gets paid as much as the big tech CEOs while making way less profit.

Have you had any recalibration issues? Some of the other non-ultra Ecoflows have an issue where the display does not show accurately and they have to drain to 0% and go to full for the % capacity to show correctly. I'm hoping this issue doesn't exist with the Ultras but not sure. To me that issue is a huge flaw and should never be happening.
Not that I am aware of, but I have it set to 25% minimum before it will automatically recharge so it hasn't dropped much below 25% thus far.

At least it's sold through Costco so maybe they will ship these?

If they are shipping from EF I would be wary though. They took thousands of orders over prime days charged everyone's cards, sent out fake tracking numbers and never shipped.
When I ordered the 12 kWh via Costcto it took about a bit over a week or so for the inverter to arrive, and then another week for the two batteries to arrive.

If you are in Sacramento and have SMUD, you can get up to $10k towards Powerwall's if you sign up for their load sharing program. After tax credit and rebate from SMUD, you can have 2 Powerwall's (27 kWh) for around $5k.

Quote from duc135 :
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?
Food in the fridge. That alone cost hundreds of dollars.

Would you be able to charge it and go off the grid until it runs out of battery and then solar charge it again. Is this an option?
Yes, that should work. As long as the batteries have charge the inverter can be turned on and then the AC and/or DC (the USB ports) ports can be enabled or disabled at will. They even have an adapter (EV X-Stream Adapter) for the DPU to let you charge it from an EV charger (J1772) plug at up to 7.2 kW, I imagine for that specific scenario.

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.
Highest AC charging rate for the standard 120V wall plug input is 1600 watts. 1.6 kW * 6 hours is only 9.6 kW, so no, it can't be fully recharged (if it was fully discharged) in that 12a-6a window. Fully recharging in that short 6 hour window would require using the EV X-Stream adapter accessory & your EV charger (assuming it is a level 2 charger that can output > 3 kW).

Correction: Highest charging rate at 120V is the full 15A, so 1800W. That requires the charging rate switch be set to the left. When the switch is set to the right you can configure the maximum charging rate via the app, and I think the maximum allowed was 1600W. Note that using the full 15A on a 15A circuit for an extended period is not a good idea (sustained load should be 80% of the circuit capacity).

I was just testing this, along with how it handled input depending on switch position when output was > than the input supported (I noticed the manual said the behavior differs depending on switch position) and I wound up tripping both circuits in a tandem 15A breaker. I think it was a side effect of the DPU pulling the full 15A on one side and my level 1 EV charger pulling 13.5-14A on the other side. Apparently running one circuit a smidge over 15A and the other at about 14.5A (EV charger + other garage stuff) caused the entire breaker to heat up enough that both circuits tripped at once.

Yup.. I'm fully planning to hard wire it with a high amperage circuit. I'm not too sure if ecoflow by default only charges with a 15 A input. Is this correct?

Quote from StrategyFreak :
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
Inverter overhead for the full charge/discharge path is about 18% (I'm guessing ~9% on the charge path and then ~9% for the discharge path) from what I've seen. Even using the standby ports X-Fusion bit to more or less bypass the inverter doesn't help much since the inverter is constantly pulling from the battery for the online UPS ports whether or not anything is plugged into those ports.

I actually forgot to factor in the inverter overhead when I did my cost calculations. Looking at my power draw before & after the DPU found that I am actually using about 18-20% more power with the DPU than before. Doing the math I found that even though I am using more power, because the peak rate is about 3x higher than the off peak rate the TOU power shift still saves me a little bit of money, but not as much as I initially calculated.

edi: x-path -> X-Fusion (I should have checked the name)

Will this charge an iPhone?
Actually, yes, it will. And your tablet. And your laptop. And probably some other random USB-powered device. All at the same time. It has 2x USB-A (12W per port, 24W total) and 2x USB-C ports (up to 100W per port, 200W total).
