Looks like all motor no capacitors
If so,then the motor will handle 12v ..
what duse the controller system look like ??
any capasitors ?
What voltage are they listed 5v 16v???
What stops the shutters from rotating past open and closed? ?
if capasitors are marked as 14.7v or higher , then plug it in add a choke cable (to activate it) and done?
if marked as 5v, then use a cell phone charger as a power supply ... ...
If the vent has make or break contacts for stops then you can just add a toggle switch and flip between positions
