EG4 Chargeverter Grid/Gen Question?

[Barclke]

Just starting out and trying to figure out if I can use an 240v ON-OFF-ON disconnect switch from either GRID power (from main panel) or from Generator power (inlet plug) to a 240v outlet and plug the EG4 Chargeverter into it to charge a rack of EG4 batteries. GRID would keep the batteries charged until a Grid Down condition, where the Generator will then be used to charge the batteries. Solar will come later.

I want to use the EG4 6000xp inverter (and possibly expanding to multiple 6000xp in future) to connect to a sub-panel combiner box with a few local breakers to run pool heater and pump. Also run a connection back from the combiner box to my main with a 100a breaker with an interlock switch in case of GRID failure.

I'm just trying to figure out the best way to avoid having a GRID down event, and then feeding the main panel from the Inverter, but then having the main panel feeding back into the Grid In breakers on the 6000xp inverter. I know I could throw some breakers to avoid the situation, but I'm thinking about trying to explain this to others. I was hoping in a Grid Down situation to flip the interlock on the main and then position the ON-OFF-ON disconnect switch from the Grid position to the Generator position.

Any advice would be appreciated.

Yes, that's a good way to do it.

Should both feeds from the grid and generator inlet be set to 30 amp 240 volt into the ON-OFF-ON SWITCH into a 30 amp plug for the chargeverter?

Can the chargeverter settings remain the same to charge the EG4 batteries?

Can be, if everything is happy with that.
