2. I am using a new 50 amp cord. Plugged into my receptacle it’s tests just like the plug.
3. From the plug it goes directly to my Watchdog EMS.
4. From the EMS it runs into my switch (AC/Generator)
5. From the switch to my Victron Energy Multiplus 3000 Watt 12 volt inverter and 120 amp battery charger.
6. From the Inverter it goes to the batteries (charger) and to the AC panel.
Got a bunch of other solar equipment in there that the do their things and eventually get back to the inverter to store in the batteries or use in the RV.
As I understand the EMS missing neutral error message that I received is indicating the system is not detecting a neutral on the line inside the rv to complete the circuit. Since it is only connected through the switch to the inverter that problem has to be from the inverter back to the plug.
The neutral wire from the watchdog isn’t finding a neutral on the switch or more likely the inverter.
Does this make sense?
Thanks for the responses.

Well Bud, I didn't wire your Inverter/Charger but the way it should work is:
From the ATS The AC SP goes directly into the Power Center to the incoming Main AC Breaker pair.
The Main AC Breaker pair powers the AC buss and each of the individual AC breakers including a breaker for your Inverter/Charger. The AC loads are all downstream of their respective breakers including the Charger load.
The charger supplies the House batteries and DC loads through the house battery disconnect latching relay commonly known as the USE/STORE or Master Power switch.
When no SP or generator is available your Inverter/Charger switches to Inverter mode and powers the AC load center back through its respective breaker. The Main AC Power breaker pair are not even in the circuit at that point.
So you can see where the EMS is only concerned with incoming power and connections from the SP pole through the SP cable to the EMS. With your EMS before the ATS it is not even concerned with your ATS connections.
