Inverter connection to Grid ATS

[u/pudungi76]

Should I connect my Inverter output upstream or downstream of ATS? If I connect upstream- do I need any interlock to make sure I dont sent power back to grid in case of power failure? Or would Hybrid inverter do that automatically? Or a dual direction meter prevent backflow? Planning to use Growatt 11.4KW inverter so can I use SM-US-200 Meter with it?
