E21 Solar wiring diagram

I'm in the final stages of 2019 E21 solar install. So far have installed 60 amp/100v controller and 60v/327 watt panel which all work great. Now going to install transfer switch and 2000W inverter and have a couple of questions.

(1) Should the transfer switch be installed on the input side of the EMS or on the output side? Seems like the EMS will throw an open ground code if TS is installed on input side so might as well install it on output side.

(2) Should AC to Air conditioner, AC to water heater, and AC to refrigerator be moved to an independent breaker block so they are not inadvertently energized when inverter is activated?

How does ETI do it? Have looked for diagram of ETI solar setup to no avail. Love this forum but search function leaves a bit to be desired. Thanks in advance.

Install to the output side of the EMS. Done right no need to check. Actually, I wired it right into the transfer switch.

The way I did it, and Escape does, is to isolate the convenience outlet feeds (2 of them unless you add another) to a separate small breaker box fed by a 30A feed through the transfer switch, where you also feed the inverter to. It will always feed through the AC pedestal unless the inverter is turned on, then automatically uses that for the feed.

That makes sense. Thanks for the speedy help, plan on cutting into it this afternoon.
