They are typically reduced to 800W upstream. And you should plug only one into one current.
At the end it depends in the strength/ thickness of your power cable.
What happens when you plug in more than one? Is there some kind of safety circuitry that detects this and shuts it off?
I don’t think so.
Even the correct cable connection is essential - parallel or serial PV panels into the inverter.
If you do not read the fck manual, you should not play with power toys.
Seems like the safest thing to do is to design products to fail safely even if the owner doesn't follow the manual. Relying on the competence of end users alone is, in my opinion, not enough.
Those systems are save. However, one can always crash it, if not used properly or fiddling around.
Same as you can refuel diesel in your petrol car. You can’t avoid dumb users entirely.
In the U.S., at least, diesel fuel dispenser nozzles don't fit in a typical gasoline car. The engineers have intentionally designed standards to reduce human error.
That's what should happen with any home electrical appliances, to reduce dangerous practices. It can't be eliminated entirely, but things should be designed assuming that people don't follow directions and don't read the manual, have safety features that physically or electronically prevent power from going to the wrong place or in the wrong quantities.
