depending on the wire size, you may need an extra line to the battery. once the amps get so high you have to either replace the cable with a thicker one or add a second. so this now gives you the option of maxing out that controler, then adding a second controler and panels to it.
if you look on the wires themselves the Gage of the wire should be written on it and that will tell you how much amprage that wire can handle. so your system you have now, you can only put two 24V panels on it and the controler will be maxed out because it can only handle 100 volts of input ( the short circut voltage of the panel that is used for this ) so if thoes cables actualy go to where you suspect you could put another one of thoes controlers in and two more panels. as you go larger in controlers the price gets more expensive like crazy.
there is also the possibility that who ever installed the solar system didn't realize there was a already installed system, or that stuff wasnt in the right spot for them, so they ran whole new wires for the install. I would ask the dealer whats going on and see if they know
You suggestion concerning the need for another controller makes sense. Large wires are 6 ga. The single smaller wire is 12 ga. to others following, the current system was factory installed by Northwood. No one else has touched it.

I am pretty good with electrical issues, but this solar stuff is new to me.
New travel trailer Solex4 - 400 watt panel system TBB power - Mppt solar mate charge controller 100V-40A
Inside the compartment where the controller and breakers are mounted, are a bundle of wires with cut off ends. Just cut flush with no wire nuts or anything else. Two 4 or 6 gage wires in Red and Black and one 10 or maybe 12 ga wire in white all bundled together with a tape tag reading \"Solar\". Then 2 more wires (6 ga?) one white and one black tagged Battery. Checked for power at each wire and find nothing.
Using the \"SWAG\" method (scientific wild as* guess), I figure it's wiring for additional solar panels if you want to install them later, or am I way off track here?

You suggestion concerning the need for another controller makes sense. Large wires are 6 ga. The single smaller wire is 12 ga. to others following, the current system was factory installed by Northwood. No one else has touched it.

depending on the wire size, you may need an extra line to the battery. once the amps get so high you have to either replace the cable with a thicker one or add a second. so this now gives you the option of maxing out that controler, then adding a second controler and panels to it.
if you look on the wires themselves the Gage of the wire should be written on it and that will tell you how much amprage that wire can handle. so your system you have now, you can only put two 24V panels on it and the controler will be maxed out because it can only handle 100 volts of input ( the short circut voltage of the panel that is used for this ) so if thoes cables actualy go to where you suspect you could put another one of thoes controlers in and two more panels. as you go larger in controlers the price gets more expensive like crazy.
there is also the possibility that who ever installed the solar system didn't realize there was a already installed system, or that stuff wasnt in the right spot for them, so they ran whole new wires for the install. I would ask the dealer whats going on and see if they know

its the smaller single wire that is realy confusing me. unless its a trigger wire for somthing I can't think of why have a single wire.
