Quality construction does the job as it should. I have not tested it over 2500w because the battery does not allow it, but it works perfectly up to that point. The only thing I did not like is the fans and the noise they make. If you have it indoors, they can be heard, so it is good to place it in a location with a door. It replaces the company's simple 2000w inverter, which was much more insensitive with its fans, which, although a little noisier, only turned on briefly and only if it gave a high load. This one works continuously now in the summer just because it is open. Overall, for the money I got it (700€) I am satisfied.

Sturdy construction. It doesn't seem like it's Chinese. Reliable. Tested off grid with its full load. Time will tell. First impressions, however, are much better than some other cheap Chinese products.
