Y Branch Parallel Connector: 1 male to 2 female and 1 female to 2 male solar connectors can connect two solar panels in parallel to provide greater power usage
Wide Application: The solar Y connector is made of PPO and tinned copper and is compatible with various solar cables: 14-10 AWG (1.5 mm² - 6 mm²)
IP68 Waterproof: Better waterproof and dustproof performance than IP67, VL94-V0 flame retardant grade, working temperature -49 ℉-194 ℉, which can work normally in harsh environments
Plug and Play: The solar Y branch is connected by pressing and unlocked by pressing the buckles on both sides, and will not slip off easily
Technical Specification: Solar cable rated current: 30 A, rated voltage: DC 1000 V; Suitable for most solar systems

Best, maybe mandatory, that all panels interconnected are the same design/ratings.
It's that fleeting thought after a large DIY project- connecting Frankenstein for the first time.
More like a possible burn up. Not all MC4-compatible connectors are ... compatible with each other. Checking forums (and the occasional transparent tech support of manufacturers) for horror stories might identify all the incompatible combinations. Then all's left is the luck in quality control of the prebuilt (or diy) crimp and connector body. Perhaps a (4-wire) mili-ohm meter reading- before/after a few disconnect cycles is a bit overkill, but depends on the power it's pumping and if the panels are on a very old shake roof. Contact resistance = fire.
In for 4, thanks!

Do not connect the panels in series. Two 110W panels in series would exceed the input voltage limit (max 60V) of the Delta 2 and could damage the unit. In parallel, the voltage matches a single panel's voltage (say, ~22V), while the current doubles (if each panel outputs about 6A, you'll have ~12A total — well within Delta 2's 15A maximum).
Just do the math and it's no problem.

Literally, the last sentence of my reply was this. copied and pasted. "I suggest wiring in series as long as your voltage doesn't exceed whatever device you are plugging intos max voltage rating."
Lastly, we would need to know the exact voltage of the 110 watt panels, which we dont. Most 110 panels are under 30 volts. so 2 nornal 110 watt panels in series wouldnt exceed 60v. and would be fine.
Edit. Since I didn't know, but had a hunch,.. I went to check what the voltage of what those ecoflow 110 panels actually are. Low and behold, I discovered they are only 21.8V each. so 2 in series would be well below the 60v max limit. So, I would 100% wire them in series.

You answered someone asking how they should link up the 2 panels without even bothering to check the specs of the device they said they were connecting then recommended series assuming they would know one way or the other what the input voltage max was. I merely provided an answer they could actually USE for the specific situation THEY ASKED FOR. It's not all about you.
Given I have a delta 2 and 2 ecoflow panels and your answer was not sufficient to answer the question for ME I'll stand by the answer I had to go look up after reading what you wrote.

While you were busy looking things up perhaps you should have tried looking up the device they said they were using:
The EcoFlow River 2 Pro solar connector accepts a maximum input voltage of 50V (solar input range: 11–50V), with a limit of 13A and 220W maximum input power. Using panels with an open circuit voltage above 50V is not recommended, as it could damage the device. In any case, added you to ignore...feel free to keep rambling.
