After being enticed to upgrade my firmware, I am now looking through the ESS menu and see that the options have changed a little.
I was wondering how the “Grid metering” menu item operates. If I set it to “Inverter/Charger”, would it prevent backfeed on AC-In?
Also, I see “Grid feed-in” now leads you to a sub-menu. I assume both AC-coupled PV and DC-coupled PV feed in excess should be off (in the South African normal use case)? The default option seems to have AC-coupled PV feed in excess on. That would probably anyways only matter in the case of a Fronius setup?
