If the inverter is connected to a 40A breaker it will never output 10 kW of AC Power.Today's peak was 7.57kw.
I have the new 400w Tesla panels.
I was told the 7.6kw inverter can go up to about 10kw. Is that not correct?
It may accept 10 kW rating of DC panels or more, but the peak will not exceed the inverter output rating.
