Dynamic connection with KH9.9?

Is anyone on dynamic connection with KH9.9 inverter? It should allow up to 10kW export rather than just 5kW. I think it is available with Energex in Brisbane:

Does it generally work well? Does it need extra physical wiring or equipment? Any reasons to stick with fixed 5KW export rather than go dynamic?

Thanks!

From a non-Australian point of view.

What is better for you?
5kW export 24/7 or 10kW for demand sessions, but with a possible 1.5kW minimum.

What I am thinking is, if you have 5kW for 5 hrs, this gives you 25kWh at $ cents rate. Now if you have 10kW for 1hr, and 1.5kW for 4 hrs, adds up to 16kWh exported... if the 10kW is very high, this could be worth it.


Hopefully someone with first hand experience can let you know if this is a good idea.

Yes, wondering if it is worth bothering about. Although potentially may get higher rate during a peak period on another plan.

So far it costs at least $250 for application now. Also sounds like I need to get a GSD installed, so cost may be even more.
