(Note I still have to put in an Inverter and would like to upgrade to Lithium).
You should measure the wire thickness (AWG) and then check on this chart below to see the max amps that wire can support. I would assume the cable is 15 ft or less in length.

12 AWG is 10 amps, or 10 A * 12V =120W
10 AWG is 20 amps, or 20 A * 12V =240W

My understanding is that the solar ready just means the wires have been run through the RV and that the MC4 connector is installed on the roof. You have to then supply the panels and the charger for the battery.
