Solar ready usually means that it is ready for the solar panel on the roof to be installed later. I do not know if it includes the solar controller. If you do not want to put a panel on your roof later, then it is probably not what you want.
If you want a solar controller and quick connect jack installed for later use with a portable panel, I would ask specifically if that is something they are willing to do for you.
Solar can seem all confusing as you first start considering it, but it gets easier.
