Most of these you need to supply 48V to the controller pin to keep it awake without the OBC present. Without an input there the controller goes into lockout, which is usually only during charging, but the OBC can lockout the controller for other reasons as well.

If you have the 650W version Summit II it should have a pin in the output cover that can be used for controller lockout while it is charging. I'm pretty sure you connect it directly to the Blue/white on the controller. It will ground when charging to activate the lockout, and will allow 48v to the pin when it is not charging, which deactivates the lockout.
If you have the 1050w version it does this as well, but you need to install a resistor between the 48V charge wire and the controller lockout pin because it does not have one built in like the 650w does.

Hopefully Sergio knows for sure and can chime in. I did this on an IQ cart not long ago, but I don't know if the Excel controller differs in that regard.
