In addition to my Givenergy installation (16 x panels into Gen 3 5kWh inverter and 2 x 9.5 batteries) I have another PV system (4 x panels in a pergola) down the bottom of the garden connected from 4 x Enphase micro inverters inverter AC to the house supply.
Currently I assume the output from this is included in the Givenergy but only as a figure that is deducted from the grid import. Is that correct?
Is there any kind of adapter or interface that would allow me to integrate the data from this second system into my Givenergy dashboard?

Pete Thomas Is your GivEnergy system a hybrid or AC coupled inverter? I’m guessing it’s a hybrid inverter.
Short answer, no, the two systems are completely independent of each other and the GivEnergy has no way of knowing or importing data into the portal. You’re correct that the AC generated by your older PV system will be subtracted from the AC imported or exported by the GivEnergy system - which may cause some confusion in the GE system with the calculation of house load.
I have pretty much this setup, a 4kW FIT array with Growatt inverter and then a newer GivEnergy array with batteries.
The only way to amalgamate the data is to use something like Home Assistant and to put a Shelly Energy Monitor clamp on your old array so you can monitor what its generating

Yes I feared as much. The installer of the house solar mentioned did suggest he could integrate by connecting those four to one of the house strings, but that the shading was totally different and also, it would mean I'd wasted the money on the micro inverters.
Fortunately the size of your 4 panel array is going to be dwarfed by the new array so the data isn’t going to be too far out.
My setup is more complex because I have two GivEnergy hybrid inverters and whilst the gen 1 hybrids play well together, the data in the app and the portal is completely screwed. On anything other than a dull day I end up with negative consumption and other weirdness.
So for me that was another reason to move to a better monitoring platform. Here’s the sort of thing you can do in Home Assistant, shows solar today from my 3 arrays
