Hi,
After listening to the "ESS systems" event I am still not sure if I can have ESS system without Power Meter when my PV inverter is AC coupled but it does not talk to GX device.
I thing, for the PV inverter that does not communicate with GX device, I would need to measure PV energy generated by this inverter with a Power meter that is connected to GX device, so the system knows how much energy is getting from the Sun.
Am I correct?
Regards,
Marek
