No Problemo, you can passively automate this scenario by adding a sub-panel. In this case you'd simply relocate the desired circuits (say for off-grid typically, household plugs and microwave) to a sub-panel and this would (upon loss/lack of shore or genset) prevent the inverter from backfeeding other wasteful circuits in the main panel (i.e. converter, auto-switching refer, water htr, and air conditioner), thus limit inverter operations (assuming no shore power) to the sub-panel circuits alone.
To do this (assuming your inverter lacks a built-in ATS), the first ATS 'output' will need to be split to supply both the Main Panel (it's now remaining circuits) and the secondary ATS (remember, the inverter also feeds into this secondary ATS), so now the secondary ATS 'output' (now unable to backfeed), will supply only the sub-panel curcuits (say, household plugs and microwave)...
This, a nice project that during off-grid will work perfectly and passively...
