I have a Quattro 15kVA in an ESS system. Continuous kW rating of the Quattro is 12kW.
I've noticed that when I draw above 12kW, the system almost immediately sources the balance of power from the grid, even though there is sufficient battery and solar capacity. I would have expected it to, for a limited period at least, be able to deliver up to 15kW?
I'm also curious as to whether this behaviour is being controlled by the inverter itself or by the ESS assistant?
Thanks.
