Hey Dave, thanks for reaching out!
You don't need to add a controller for each panel, just as long as your controller is rated for the power of all of your panels. For example, the etrailer Solar Expansion Kit # e72PR is rated for 195 watts so two of them can be used with our Controller # e42PR which is rated for 390 watts at 12V.

Hey Dave, how did things go adding the extra solar panels to your XLR 25LRLE? Did the controller handle the total power like you expected? Your update could make it easier for others looking to expand their solar setups.
