I know a strange dissconnect/dichotomy from all of us on this subject right? maybe experience has taught us a bit about Chinese inverters and quality control... or it could bite us all in the backside on the batteries and BMS...only time will tell.
I installed my 11kW solar system in 2017 and spent the previous 2 years researching everything I could before doing it. I'm also a retired electrical engineer, but my expertise has nothing to do with solar or inverters.. or batteries for that matter.
I am a member of pretty much every solar website forum and probably most of the groups on facebook.
I say this because, even though I have almost no experience with Chinese products of this nature, I have paid close attention to the experience of others.
What I have learned is that SMA (German) products are the heavyweight champs.. Right below them are all the popular names like Outback, Midnight, Magnum, Schnieder, Victron, etc.
While it is common to find forum group postings asking questions about these products, such questions are usually due to user ignorance of the menu's, settings, and other options. And while it does happen, it is very rare to see a failure with these products.
On the flip side of this coin are the hundreds of failures I have seen with the Chinese brand products. Some are better than others, but none hold a candle to the list above. Youtube and solar forums are filled with one type of failure or another.
If you buy a Chinese brand inverter, folks need to remember to cut all the ratings by about 50%. If you get a 4000 watt unit and you want to frequently run it at 3000 watts, your reliability statistics are going to tank. On the other hand, that same 4000 watt unit will do just fine with occasional 2000 watt loads.
The problem is that even a 500 watt load can burn out some of these cheaper units with manufacturing quality defects. You won't find these kinds of problem with good inverters like the list above.
Trying to get a Chinese product warrantied is also a problem.
Everyone has to valuate their own requirements. As for us, we live in the rural countryside where the grid goes down every couple of months for up to a week at a time, and if the world goes to $hit, I want my inverter to be reliable.
Someone else who just wants something for camping might not have the same requirements.
