Just picked up. Walk through with dealer thought it didn't have solar prep. when looked at roof it has solar connection. Anyone have any idea where the wires go to or are they directly wired to the batteries without a controller?

We have a 2020 261RB and we don't have wires on the roof. We do have a Solar Power input, similar but smaller than the shore power input, that is located just forward of the passenger side pass through door.
If your dealer can't tell you what's going on with that and where the controller is, I would call KZ directly.
I would like to assume a controller is installed already, if it's "pre-wired", but I've learned not to make those kinds of assumptions.

Yeah talked to service guy he said no controller but wires should be in wall near slide out control ect. Quick check around that wall couldn't see any unused wires. It's silly but thanks for your input RV couple .

Good Day All,
We took delivery of our new 2022 Connect 241RLK last October, just in time to put it away for the winter. After reading this thread, I checked the roof, and sure enough, there is a connector for solar panels already installed. I checked with our dealer, and they have no idea what we are talking about. In all fairness, Our trailer was ordered as a 2021 in April, and solar prep was not an option. Ours is the first 2022 they received.
In any event, I have been through every cubby hole, and removed every panel I can find, and don't see where the wires from the roof are located.
As suggested, my next step is to call KZ.
eagerly awaiting information!
Paul

Paul Hello Again, Just received a reply from KZ Customer Service: " Hi Paul the plug and play on the roof is wired directly to the batteries. And there is a 10 G wire located inside of an interior wall for your controller and it should be in the wall where bedroom light switch is.

Thanks for checking with kz. It seems weird for the control module to end up in bedroom but I will check our unit to see.

Found it I think. Two wires one white one blue. Thanks for info paulg.

Our rocket club has a sea container set at the launch site and a single solar panel set up to charge the 12V batteries we use for our launch controllers. We have 5 charging controllers wired in parallel to the solar cell to charge each 12V battery. They work great. I also connected a 12V - 24V input 12V output controller to run our LED lights in the sea container. That controller burned out the first month in use because of the high voltage output by the solar panel when in full sunlight.
I would not recommend connecting a solar panel directly to a battery. You're asking for trouble. You should have a battery charging controller made to accept solar panel input in between the panel and your battery. Ours are cheap and have no controls or displays, just a few LEDs. If there is sufficient voltage from the solar panel, they charge the battery. Simple and easy. We charge 5 batteries at a time and only need them charged about every two weeks so that works for us. It should be much easier with a single solar panel, single controller and single battery.
You don't need a high dollar, fancy controller. Just a simple solar panel input, battery charging output controller.

I think that's what kz did. Solar input connection on roof from factory, wires down through bedroom wall on way to batteries, new owner adds controller splices wire in bedroom. Power into controller, power out to batteries. Is their more needed to charge batteries?

Power into controller, power out to batteries. Is their more needed to charge batteries? No, that is all. 2 wires from solar panels, 2 wires out to battery(ies). I just upgraded batteries and chargers and have a Renogy Rover40 amp that needs a home. It is a pretty large charge controller, so depending on how much solar you plan to get it might be overkill. Definitely get an MPPT controller though and wire them in series as much as you can on the roof. This will push the voltage up, but reduce your wire size needed. Assuming KZ didn't put a very big gauge wire in from the roof. |

10 gauge. think that's enough for 2 100 Watt panels?

at 100 Watt and 12V, that would be 8.33 Amps per panel. 10 GA is what is installed to run the 12V refrigerator on a 20 A fuse, so I would say you are good.
You will probably get more voltage and less amps from the panel, but the controller will output about 13.8V to charge the batteries so that could run 14.5 Amps from the two panels.

Thanks for the math now to find the panels and controller. Really really appreciate all the input.
