I purchased this inverter less than nine months ago, and installed it about seven months ago. Heavy cables(1/0 gauge) from LiFePo4 batteries. Used only a handful of times to power a tool battery charger that pulls a maximum of 560W. It no longer works it will power on but has no output in any of the 110v outlets. Customer service is less than helpful. Buyer beware.

My first unit only lasted 6 months but Their costumer service was great and replaced it. It’s keeping the lights on in my shed. Thanks!

I have had this for several years and it works well with my solar battery backup system. I don’t give it a ton of use but it appears well made and has always worked when I have needed it to. Can be loud when fans are running.

A toaster and a kettle draw >2100W and this thing didn't break a sweat, it was the lead-acid battery that was begging for mercy, and the inverter graciously let it live another day, shutting off at ~10V.The 3AWG wire leads are positively huge, yet barely adequate to feed this beast. Man do things get ridiculous with 12V gear when pushing close to 200A, and all I wanted was a toast and a cup of tea...

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.

Ordered this as part of my solar install on my travel trailer. My system includes an HQST 190 watt roof mounted solar panel, a Victron 75/15 MPPT solar controller, 2 Power Queen Lifepo4 Smart 100ah batteries and this Sunthysis 2000 watt Pure Sine Wave Inverter. I tried several 2000 watt inverters and none would power all of my travel trailer appliances/electronics. This inverter powers everything on my travel trailer (AC, microwave, Keurig coffee maker, tv’s, etc.), obviously not all at the same time. The LED display on the inverter shows battery charge, wattage output and fault codes. I mounted the inverter next to the batteries in the front pass through and can see the LED display with no issues. I also mounted the remote on a panel in the pass through where I can easily turn on/off the inverter. We will use this to boondock for short stays between rv parks. Better than having to fire up generator to watch tv, run my CPAP or make a cup of coffee in the morning. Very pleased with this inverter so far.

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.
