That's not to mention the outrageous price for what you get - 7.2kW and 7.2kWh. Another $1kish will get you a 20+kW NG standby generator with 200Amp transfer switch, that will run essentially forever.
Yes I understand these have their place - if you need silent power, and your power demands aren't extreme, these might work, but they're a super pricey solution.
One benefit of the Hondas (among others):
"Limitless" run time, constrained only by fuel availability.
Some benefits of the Delta 2 Max:
-As others may have already said: silent (OK sure, cooling fans if you're cranking the output).
-Can be run inside.
-Can be charged via solar (I have 520W of solar capacity for now, for what it's worth)
In an extended power outage, I can see myself relying on the Hondas during the day, and then using the Delta 2 Max overnight. Zero noise, zero theft potential, I can have it running inside without killing myself. Can run the fridge, router, access points, some lights, etc. overnight, then be charged up during the day.
I'll be expanding my battery capacity, but will probably go with DIY. 48V LFP battery, inverter, etc. You can achieve better Wh/$ doing DIY (sometimes a lot more), compared to EcoFlow or similar all-in-one devices. Maybe not when you're spending $1,000. An EcoFlow device can be simpler and more appealing at that price point. But for the ~$4,000 you'd spend on this deal, you could build a higher capacity DIY system.
For example... ~$2,518 will buy you 2x EG4 48V 100Ah server rack batteries. Total 10.24Wh (versus 7.2kWh from the two Delta Pro's). And you have ~$1,500 left over to buy a nice inverter. For example $1,400 for an EG4 6000XP Off-Grid Inverter (8000W PV Input | 6000W Output | 480V VOC Input | 48V 120/240V Split Phase). Same ~$4,000 for +42% Wh, plus the ability to easily add capacity with other battery brands and types.
Anyway. Plus and minus for both, of course. Those batteries and that inverter have the same 5-year warranty that the Delta Pros do. But the batteries will have a 10 year warranty if paired with a better EG4 inverter. On the other hand, the Delta Pro is "all in one", has a decent phone application, has wheels + handle built in, etc. etc. I see the appeal of that, and have no regrets with my Delta 2 Max. Have already used it once during an outage.

Is that what you mean?
Again, it all boils down to whether 30A, 7200wh is enough to power your house. If you have central AC that will be tough in the summertime.
click the blue "overview" link to see the text copied below:
"More watt-hours at home The Extra Battery can be integrated to your home's wiring when connected to DELTA Pro. These battery units become part of your home's peak shaving and emergency power solutions."
EDIT: I don't see any mention of it in the user manual. That web page comment might be marketing misdirection/lies. https://www.electricgen

1) If you use the 240V adapter then you lose the ability to charge the Delta Pro from AC. I know... its crazy. To charge from AC you'd need to unplug the adapter from both the DPs, then once it finished charging plug it back in. I am just using some surge protectors plugged into a single DP and plugging all my equipment into that. The DP has UPS capabilities, so you don't have to worry about anything going dead if you drain the battery or if the power goes out suddenly.
2) Peak shaving means some amount of automation. The ecoflow automations are pretty limited, basically just trigger on time, battery status, or weather. I am using Home assistant to control the DP, and I have some more complex automations that tie it in to the state of my home solar panels/battery to act as another energy sink when excess solar is available, as well as intelligently charging at night to meet the next day's demand without storing too much. Prior to getting solar I used home assistant to handle turning on and off the DP charging during off-peak times.
3) The built-in solar capacity is actually pretty good, and if you can get your hands on some 400W panels then 3 of those would be fantastic for a single DP. However, the cost of the Ecoflow panels are way too high for what you get. Either go surplus (I got a 400W panel for $120), or call up a local installer and just source some new panels.
4) Customer support is basically non-existent. Buy your DPs from a major retailer (Costco, Home Depot, etc) so that you at least have some recourse should things go pear-shaped. I luckily haven't had to deal with this, but the ecoflow reddit has some pretty bad stories.
