If you want speedy support, I DON'T recommend this product. I bought this same unit, with a Smart Home Panel 2, from Costco on Black Friday 2024. I received everything (did you know a trolley is included?) in mid-December 2024 and installed it myself within a few days. The battery backup didn't work, so I contacted Ecoflow to get a replacement. They required a lot of proof, pictures and videos, before doing anything else. I even spoke over the phone and did diagnostics with a digital multi meter on a live panel, checking for voltages and shorts. Ecoflow determined the panel was defective, and sent a new one. They offered an electrician to replace the panel, but I didn't trust their work since their website showed questionable workmanship. Anyways, I got the new panel, and guess what, it still didn't work. For 2 months, they claimed their "R&D" team was "looking into it", but I had to get their social media team involved to move it faster. The social media team was able to get a replacement inverter sent to me within 2 or 3 days of my contact. I got the inverter after a week, and it turns out, the smart port was the issue. In the end, I believe I had issues with both the SHP2 as well as the DPU inverter. Everything on my original inverter worked, I tested 120V on each of the 20A AC outlets, 240V on the 30A outlet, and the USB ports also worked. I was able to discharge all 3 batteries and was even able to charge all 3 batteries through the SHP2 at 7200W input. I just couldn't cut over to battery power, which was the whole point to getting this system.
PS: EcoFlow uses FedEx, and almost all the boxes I received were in rough shape. Ecoflow has good packing, but the extremely rough handling from FedEx is still a concern.
TLDR: Ecoflow took 5 months to resolve a defective Smart Home Panel 2 and inverter. Be prepared to send lots of evidence (pictures and videos) and at least 1 day per response. If I had to do again, I wouldn't get the SHP2. Just install an interlock kit with a generator inlet.

long way to go to get to a real slickdeal price. i paid $2799 at home depot for the dp w/1 battery and then a year later $1599 for 2nd battery also at hd. that's $6300 w/tax (for this costco pkg) if i had chose to get a 3rd battery. be patient, it will drop.
