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 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.
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.

And, if you happen to have solar or are planning to get it, then it has a built-in 11.5kW inverter, which is enough to power 95% of homes (with a single unit).
Just for info. I also bought the smart home panel 2 last time and it's been working decent. I had 2 EF delta pro, but for some reason they aren't working with my SHP2 (trouble shooting with EF currently, they are slooooow). For some reason TOU is not working for me. I have PG&E, so I just use time of use, which is does the job as I only have peak and off peak rates. The app advice you to only charge the battery to 90% and only allows you to set 10% as the lowest to preserve for backup. So for 18kwh, you only get 14.4kwh to be used during peak hour.
PW's were a great deal for a while. So great that Tesla took deposits from thousands of us yet they didn't deliver the hardware years after they said they would. These days I honestly don't know why anyone would buy a PW given their less than desirable cost or battery chemistry when there are cheaper (per kWh) and better long term battery chemistry available. It's like people that do buy them want to make sure everyone knows they were gouged for an inferior product so that they could feed some excess $ to some massive insanely rich dbag... Bravo!
Also, since the caution is explicitly referencing the AC input I suspect that it may not apply to the EV charging adapter since that uses a different input on the side of the inverter. That's just a guess; I don't know for sure so if you are planning to use 240V I recommend reaching out to support for clarification.
edit: X-Path should have been X-Fusion (I forgot what they called their bypass)

To pay 2-3x more? lol - you are VERY misinformed.
They sell an x-stream adapter that allows u to charge at 30a at 240v so about 7.2kwh which would be more than sufficient to get 18kwh every day - theoretically u could get a little over 40kwh each nigh during those 6 hours.
If u could add a little bit solar u may be able to reach roi sooner.
Also I haven't found the round trip efficiency of the EcoFlow products all that great. The inverter and WiFi connection use power at idle and larger loads generate more heat etc. Depending on the use case you may only get about 80% efficiently meaning for every kWh u feed it you get .8kwh usable.

I'm not sure what the wifi power draw is but it can be disabled and switched back to bluetooth mode by doing the wifi reset, although that process requires unplugging & shutting the inverter off (it can not be turned off if it sees AC input). No idea what, if any, power savings there may be for bluetooth versus wifi. I've used both modes and didn't notice much of a difference between the two in my power monitoring system, so probably not much benefit. I think most of the conversion loss/internal power draw is from the inverter itself since it is always pulling from the battery to some degree due to the online UPS ports (assuming the AC output is on).

But anyways the tesla powerwall system is actually pretty nice and I believe the lowest cost per kw unless you want to go with sometihng like eg4 batteries.
Telsas system also seems to be the one integrating with the power companies (selling back power when they need it) Not sure if other manufacturers have that.

costco should have no problem accepting the return
