changing PV panels - effect on FIT?

I think it would cause problems at the extremes.

This is why the limit is quite low at 16A, no reason why it could not be 40A in isolation, trouble is it is not isolated, but part of a dynamic system.

The National Grid relies more on prediction than dynamic management, the last thing it wants is two or 3 nearby sub networks all running and different voltages.

Great explanation but I thought the only stipulation was the 16 amps, I have not seen anything where timing has been mentioned. I know the local network must be able to cope with the predicted input which is why some are charged for upgrading their local transformer. Again my point is if I were limited to 16 amps (at any time) having more panels would still give the network the max 16 amps controlled by my inverter (or am I bring thick 🤷‍♂️)

Not sure if your talking about the limits set by 2 differing organisations. The 16amp limit is set by the DNOs and as you say is governed by the inverter. OFGEMs FIT scheme looks at generation capacity which is the capacity of the panels

Ah, I didn’t know that ( i never got around to fitting PV to my build before I lost it 😣) thanks 👍
