Cool 2018 Gemini Solar Pre installed wiring, charge controller?

Forgive if this topic has been covered and point me to its location, Thanks!

Purchased the Gemini 23TK new 2018. It was my understanding from CW the Rv has some sort of solar starter kit already installed. this was a standard feature on most units as far as they explained. I have seen the two solar wire connectors on the roof for the solar pane connections.

Question: I am looking for knowledge concerning the presents of a charge controller ? Does the current inverter permit solar PV wire connections/termination or is there a separate charge controller to wire the PV into? Or do I need to get a charge controller appropriate for the Wattage desired?

If the equipment is already installed, is it located at the inverter, power distribution panel area of the Gemini ?

I am wondering what the largest capacity solar collector these set ups typically accept? And if the type of panel is crucial?

Just looking for 400 to 600 watts to top us off on longer boondocking stays.

Thanks in advance.

Hi Elcapitain. Welcome to the forum.

The solar controller is separate from the inverter(if you have an inverter). Coaches usually come with a converter and an inverter is usually considered optional. If your coach was sold with solar prewired, you should have a solar control panel somewhere inside the coach. It may be inside a cabinet or on the wall. Mine came with a 100 watt solar panel and controller which is a Go Power 10 amp digital Solar Controller inside the cabinet above my refrigerator. There should be 4 wires that go into it(two from the solar panel on the roof and two going to charge the coach batteries). On the roof might be a metal box or panel cover that hold the wires you need to connect to the solar panel(s) you install on the roof.

Hopefully that helps you out. You can check out the Go Power 10 amp solar controller online to see what it looks like.

Paul

Thanks Paul, Yup, converter ! I just added a 3kw inverter. I am going to look above the fridge as there is a lot going on up there and in and around the converter for the other end of wires I see on the roof and the battery charge wires. Wasn't sure if pre wired ment it had a charge controller or the solar panel wires plug into the converter and the converter is dual purpose.... I am going to get into it this morning and try to locate what is where and try to determain if I need to get the charge controller. (I'm thinking that as cheap as Thor is, nothing has been supplied other than what was necessary) thanks for your information!

The 2018 model year only has the rooftop connection and no charge controller. I have looked into installing a 100 watt solar kit and the best deal I have found on Amazon was made by Renogy, my local RV shop will install it for $200. BTW the wire from the rooftop
should be somewhere behind the converter/fuse box and should be orange

The wires that Thor used to install my solar panel system are orange and white wires.
