I got the delta 3 with a 220w panel in one of the previous deals for $699. Now looking at the delta 3 plus + 400w panel for $899.Trying to understand if it turns out that the original purchase doesn't match my needs and I need to swap. Thanks!
What I failed to calculate was what the inverter uses just being on

This matters for folks in places like welfare state California where electricity is .31c per kilowatt in the morning, and .62c in the evening. A 1.5kwh battery won't make much of a dent in the bill, but if you had a couple expansion packs it would save you a little money over time rather than sitting on a shelf waiting for the next camping trip or power outage.
The best would be to pick up a cheap 400w full size solar panel used, or two of them to connect. The portable panels are very expensive for the output.

note it's not really a UPS
there's no brownout or overvoltage protection
note no ecoflow will charge at more than 8amps input so 12v x 8amp = 110watt limit unless you input in series at 24v 36v or 48v
the interface is quirky and doesn't work if internet is down
people have bricked units during firmware update
and firmware update will turn battery off/on so you cannot update if using it other than grid bypass
for $450 it's worth it, I would not pay more
the battery inside is 51.2volts @ 30amps
this note is incorrect. all current delta series models by spec have 15A solar input (Delta pro 3 LowPV input is 20A. and some previous generation delta like Delta mini (13A) or original delta max (10A) are lower)
you need the correct Solar XT60i input cable (EF uses XT60i middle pin bonded to negative to allow >8A "Solar". middle pin to postive limits to 8A "Car", and no middle pin bond found on most third party XT60i cables the power station is left to guess "Solar" or "Car" on it's own based on voltage and current characteristics and mis-identification is common.

DC Input Port (XT60) Solar Input: 11-60V⎓15A, 500W Max
Car Input: 12V⎓8A Max
Ah okay, I am misremembering the car input is limited to 8amps
But you are right the XT60 is 15amps
12volt x 15 = 180 watts
really we want 24 volts minimum for solar, higher is better for efficiency
I still do not understand how solar panels work in series for 24 volts if they have diodes to prevent voltage input
I was surprised, when connected to my transfer switch at night around midnight, when everything was off I was getting 150-250 watts.
The only thing on at that time was my fridge and wifi/modem.
