OK, I have dug deeper and posted more PICS on my site. Learning some interesting things with the 50 amp Intellitec Energy Management system.
I opened the panel and verified the Xantrex inverter is indeed connected to the panels ground. The orange romex comes into the panel from the bottom right.
Also, looking close you can see a choke around the common feed (white) just behind the black and red feeds. This senses the amp draw for the EMS.
To the extreme right you can see the Intellitec Energy management system.
The EMS has 4 relays on the 120 vac side to control up to 4 120 vac circuits. Whats interesting is that it appeares that at one time the Xantrex inverter was managed by the EMS.
I do know that when first started up that converter can put quite a draw on the AC side when it starts bulk charging. I have to remember to immediately choke it back on the front panel (bottom pic 20/30 amp select) when I plug into 20 amp. It defaults to 30 but will automatically select 50 when I plug into 50 amp.
Really not much to these Energy Management Systems
from top to bottom;
relay 4 to relay 1. Two connections/circuit. From the breaker to the EMS relay then from the relay to the circuit.

Note the last "slot" is not labeled. I believe the inverter was at one time was managed by the EMS.
Here's a shot of the schematic for the EMS for those who want to take a closer look
