Question to all the technical geeks with AIO / Gateways:
My present installation is an AIO with Gateway, with the PV feed from a 5kw Solax string inverter.
I am considering adding a 2nd PV array and string inverter. Would the 2nd string inverter's AC output simply be wired in parallel to the first's to the Gateway's PV input ?
I know this is an issue for the installer and they will do everything as is legally required, but I just want to know the basics before starting to talk to them.
