Yeah understood. But this is why they have a surge rating. 3000W continuous but 6000W absolute peak for a few seconds etc.
My PIP4048 handles anything. Inductive/resistive, if it's under 4kW it will do it. It's happy running a fridge which is inductive and has a high spike current.
There are a multitude of different reasons why in that video his inverter might have cut out. Not the least of which is that it looks like he's using the standard cables that come with it, which are not at all good enough for powering 3kW. Also it appears that Renogy make different versions of the same thing.
As I mention earlier too, several people seem to suggest that there's one with high output terminals on it ? Anyway, If we look at the reviews nobody seems to be having that issue with the UK supplied 3kW ones. I guess if it didn't work it's easy to send back anyway. The only reason I picked this inverter is because of it's UPS/Transfer switch.
Sounds like I'm shilling for Renogy now haha. Just happy with mine I guess.
