Hi,

I am currently testing having PV inverter on the AC-out side of my MP-II.

The ESS is not yet implemented because I do not know yet if ESS will work without Power Meter.

The worry I have is, what will happen when grid fails, my battery is full and PV is producing allot of energy that has nowhere to go.

Will there be frequency shift sent to the PV inverter to turn it down, or it is only done when the ESS assistant is loaded?

Regards,

Marek

There is also a "PV Inverter assistant" that will do that.

So as it is now, without assistants, it will not FQ shift?

Also, what happens if GX does not know of PV inverter, This "PV inverter assistant" will know what to do? Will it even load?

Regards,

Marek
