I had quotes to install 42kwh, 10kw inverter in Victoria
aud 6500 for ac coupling
aud 7500 for dc coupling

current inverter is a 5kw growatt inverter. aith 6.6kw solar it seems it can be controlled via custom signal but seems abit of a hack.

planning to go on a plan like Amber where I would need to be able to curtail any output to the grid.

So the only option is dc coupling? Or is it possible for the fox inverter to connect to the growatt inverter to cut any export for instance?

To do what you are trying to do you would need DC coupled panels to the Fox system, that's the only way it can hard limit the amount of export by derating the MPPT's

Having DC coupled would improve your efficiency slightly as you'd only have one set of losses from the single inverter.
