My hunch, but you should ask Renogy:

Watts = Amps X Volts

The specs on your panels are:
Max watts: 200
Optimal volts: 18.5
Optimal amps: 10.5

It more or less balances out: 10.5*18.5=194.
Done another way 200w / 18.5v = 10.8a which is a little more than 10.5, so assuming some loss in there makes sense.

If you adjust the 18.5 to something between 12-14.4, you get an answer much closer to the 120 you're seeing.
10.5*14.4=151w
10.5*12=126w

It sounds like you have everything hooked up correctly. My one comment is if you're trying to move 10+ amps 25 feet to the batteries, you should have 8awg (thicker won't hurt) cable to have minimal voltage drop. Probably not a big deal (and you likely already have it) since 8awg is not all that expensive or overly thick.

Thanks! That's very helpful!

I also thought the 25ft cable might lead to voltage drop but since I plugged the panel directly into the EcoFlow and saw similar results, I'm guessing that wasn't it. EcoFlow has this on their site: Solar Charge Input 200W 10-25Vdc 12A Max, so I'm guessing that's not a problem either.

Not sure what's the best way to monitor but at least with the portable panel and battery I can continue to play with it without taking the trailer out. Probably silly question but could it be the sun is less powerful this time of year vs summer?

Time to get tires for this thing. It came from the factory with LT235/75/R15 load range C M/T tires. Looks like there is really only one option to get an ST trailer tire in this size that maintains the off-road look/protection but it's pricey. Looking like it's cheaper to go with a name brand A/T in LT sizes. Here's a few I'm considering:

Load Range C: KO2, General ATX, Toyo AT3
Load Range D: KO3
Load Range E: Wildpeak AT4W
Non-LT XL Load: Wildpeak AT4W (only 2 lbs lighter than E rated version)

This trailer is roughly 2k lbs empty and under 3500 lbs fully loaded so any one of these tires is more than capable. Since I'm hauling motos on the road 90% of the time, I'd like something that doesn't ride too rough.

Am I overthinking this? Should I get a Load Range C over an E?

I've been happy with Carlisle trailer tires, but I don't think they have 235 in a 15" my trailer tires are 225/75R15. they come in C, D, or E

I have Carlisle on my other trailers - I think they're called Carlstar now - but this is an odd size with an off-road focused look.
Here is what the manufacturer is putting on the trailers now, but they're over 50% the price of a name brand LT tire: https://trailersetgo.com/store/raini...l-trailer-tire so not sure I want to get this, especially when it came from the factory originally with an LT.
