Maybe yes, maybe no. It depends if the port that SMB installed is in parallel to the existing panel. If it is than, you would not need a controller, nor would you want one. If the panel is just port to the battery one with a controller would work. I would think the port would be in parallel to the existing panel, and the existing controller would work.
You would like to match your new portable panel as closely to the existing panel as possible. Normally that info is on back of panel. Is it zamp setup? I think they have some funky reverse polarity issue you may have to sort out.
