Installing solar to replace broken generator and using generator's wiring?

Hi guys,

I just purchased the first few elements of my solar system (100w panel, wiring and mppt 40amp charge controller), I'm planning to upgrade it gradually to a more powerful system with more panels and batteries.

My generator at the same time is done for, so I wanted to see if I could use the wiring that used to go into the generator to get it into the new charge controller and call it a day so everything would be connected just like before with my generator especially it would avoid for me to set up all the wiring to get to the auxiliary deep cycle battery.

I have different wires that were connected to the generator:

3 wires (one black, one white, one nude which I'm guessing is one hot, one neutral and ground) that go into a transfer switch box. And then separately 2 other wires a little thicker, one with a little metal loop at the end and one with a bolt at its end. I'm not exactly sure where these go, I tried to follow those cords but it ends up being a complex set of connections underneath the RV so I'm not sure.

Let me know your thoughts on this, I hope I'm clear enough explaining the situation but if not I'll be happy to give more details.

Thank you!

Again, Cyrus, I believe you should run new properly sized solar wiring from the panels to the controller and then from the controller to the batteries. Someday you will replace your generator and you'll be ready to go.
