Which Operating System and version of Gimp ? How many images to process ?
My preference is a batch plugin BIMP see: https://alessandrofrancesconi.it/projects/bimp/ There is a Windows installer and if using linux I might be able to help. No need to open the images in Gimp. See the examples on the web site. Use 'Other Gimp Procedure and search for invert.
Another way is load all the files as layers, apply a colour invert to all layers with a script, then export all the layers as individual images with another script.
