It's mainly to have as a backup or for portable power. For me, in California, I pay 39 and 49 cents per kWh delivered, so I benefit more by charging this with solar panels. I have one of these with 2 extra batteries running power to an ac that runs during the whole day time. I have another with one battery that exclusively runs a fridge and freezer. My main goal was to avoid paying as much of the peak rate from pg&e. I get more than a full discharge per day for one of the units since I have 4x 430 solar panels feeding it power while it powers the air conditioner. It doesn't usually fill the battery completely, but it keeps up with the energy use.
But I'd like to add a window ac unit to our office that just bakes because only a little cool air makes it that far. No amount of running the house ac can keep it cool so I want to add something to bring the temp down during the summer. I'd buy a 420 watt rigid panel locally and a second Ecoflow to power the window unit in the hottest part of the day. All the while serving as extra battery backup in case our power goes out.

I would make sure to try to overpanel because you won't get the full solar power per panel. For example, I have two 405w bifacial solar panels per solar input on my Delta Max 2. Each solar input has a limit of 500w so on a good day I can get 1000w of solar for about an hour or two and about 700-900w throughout the rest of the day if it's nice and sunny. Just assume you'll get about half the output from the panels. My 12k btu window ac uses around 500-1000w depending on the settings and outside weather. I usually have it set to 72-74 and it's often 90-100 here in California right now.
This Delta 2 Max can output 2400W and double capacity. I can run more critical loads concurrently and would last couple of hour when my car is disconnected.
To clarify: You can set the maximum battery charge in the phone app to increase battery life. I have it set for 85% max charge most of the time, but sometimes I take it to 99% if there's a big storm coming and power outage is expected.
It sits in the cupboard above my fridge, but needs a bit of ventilation even just sitting there passing AC through. When power goes out and comes back, there may be a few milliseconds of delay (I'm not sure), but it's short enough that the microcontroller in my fridge (not to mention the compressor) doesn't reset.
