Overall I'm giving this 5 stars, despite a few minor gripes. But considering the value, I haven't found anything else at this price that is comparable. I've gone through a couple of cheaper inverters that never achieved their rated capacity, or in one case even half of it's rated capacity, but this one does.
The DC cables this ships with are 3 AWG, which is actually pretty good. They are thick and well crimped. I still upgraded to 2 AWG cables, which you should consider as well.
Gripes:
First off, in the specs above it says "truly providing 2000W stable power with a peak power of 4000W". I see no indication on the unit, in the instructions, or in practice that this is capable of anything remotely close to 4000W, unless it's just for a small fraction of a second. I was able to get slightly over 2000W, maybe 2200W, for a few seconds at a time with no issue, but I hit about 2500W and it shut off immediately.
Secondly, and maybe most concerning, is the output AC voltage is only rated for 110v. It should be 120v, there is no reason to output 110v. I checked my unit and it was actually only running at 108v. This is getting dangerously close to being out of specification for electronics.
Lastly, the cooling fan blows toward the AC plugs, so you're actually heating up your AC connection and cord while it's running. Not ideal, but the fan does seem to move a good amount of air.
Overall this will do the job I intended it for. This can run my refrigerator, which my other cheaper inverters would not do. The startup surge over 1800W was not a problem.

Sunthysis 2000W Inverter Review
I was looking for a pure sine wave inverter to run some sensitive electronic equipment at a remote location where A/C power is not always available. I found the Sunthysis unit, and although it seemed like it could have been a newer unit to the market, the limited reviews didn't give me any issues. My first delivered unit was faulty and failed after approximately 5-minutes run time. Tech support was extremely helpful with diagnosing where the problem might be. Prior to contacting them, I'd verified the Group 31 marine deep cycle battery I used as a power source was still good. I use battery tenders on all my battery powered equipment, so I made sure not only was the battery properly topped off, but it load-tested very strong. Using a digital meter, I monitored inverter output metrics and contacted Sunthysis with the results. They guided me through a couple more tests and agreed there was probably an internal issue with the control circuitry. Sunthysis sent a replacement unit which I ran all initial tests on, including the lamp test, and the unit ran flawlessly for more than 20 minutes on the bench. The final test will come when I install the unit at its intended location for a long-term test. At this point, I'm very satisfied with Sunthysis tech support in helping me diagnose what was an issue with their first supplied product and immediately providing a replacement. Inverters are sensitive electronic devices themselves, and I understand that shipping damage to the internals could occur without visible evidence. Sunthysis' consistent communication and helpfulness resolving my issue lets me still give them 5-stars. I'll revisit this review after a full test of the units intended use as a follow up.

My truck did not come with factory air conditioning. I picked this up specifically because it was a pure sine wave inverter. I was able to bolt it under my hood in a place as to not get wet, and still get good air flow through the fans. I did not use the cables that came with it, but they were very high quality. The remote is a great feature. I have purchased a second one for my work van, the 1200 watt variety. The placement of the outlets and the orientation of the outlets was very important. Sometimes when using an inverter, it needs to be bolted flat and it limits being able to use power blocks or angle plugs if the outlets are in the wrong orientation. I'm looking at buying the next size up for my RV, and another 2000 watt for emergencies at home where I can use my battery bank.
