I haven't watched the videos that had the wifi reconnect issue yet, but mine reconnects fine on its own, both after power resets of the wifi router, 18kpv, or a combination of the two. I do have an issue where the connection shows offline for ~15 minutes at a time even though the LEDs show connected, however it always comes back on its own.
To throw one more opinion on naming conventions in the basket, I think any number in the name is perfectly acceptable because every unit has pros and cons, and if you're actually in the market for one you're going to find what fits your need the best. The "well in this specific situation this unit can do this much, but in that situation it can only do that much" makes the units incomparable with any single number. Anyone saying otherwise is focusing on the number they care about, which I'm not complaining about.
For example, if someone, just like me, never has any need for more than 12kW AC but wants to maximize solar output, the extra MPPT ability of the EG4 18kpv to do 12kW into AC while doing 6kW into batteries may be useful. (I understand there are caveats on this and am not trying to restart that discussion)
On the other hand, maybe you occasionally need to surge past 12kW doing laundry or something and you're perfectly happy only doing so when the sun is up, so the Sol-Ark 15k's ability to do 15kW when doing battery + solar is more helpful.
Both of these highlight a clear cut reason that the number in the name is actually better than the other in the right circumstance, but it's not just a "higher is better" kind of thing.
This is just one example, but there are plenty of reasons that these units are not directly comparable based on any one number, so IMO getting wrapped up on the naming convention, which doesn't and never has existed across the industry, is a waste of time.
It's just like suggesting manufacturers of cars should all label their cars according to horsepower. We'll go and compare the subaru 310 to the ford 290 and just ignore the fact I just pulled numbers for a sedan vs a truck.
