  • Suitcase solar wiring question

    Hello,
    New member here and new 2022 303 owner. I have a suit case solar panel from our previous camper and I’m wondering if I can wire it to the charge controller that came with the camper? Would I need to bypass the controller that’s on the suitcase panel? Is their a better way to wire the suitcase panel that I’m not thinking of?
    Thanks

    Chris A welcome to the forum. I am not familiar enough with the 303 to answer your question without more info. What is the controller that came with the camper? What panel do you have? Is there a solar connection on the outside of the camper?

      Bellis,
      it’s a 50a furrion charge controller I believe, with a 165W panel on the roof, all factory. No solar connection on the outside

        I would not use the factory controller, odds are the voltage of your portable panel is different than the rooftop panel. I'd just use the controller with your portable panel and connect it's output to your battery. Either through your front bay, or if you want a disconnect you could mount something to the right of the front bay door.

        Something like this:

          I agree with ncitro . I'd just wire it directly to the battery using the connection Neil linked to.

            I replaced the PCM controller and installed a Victron MPPT controller on my suitcase solar panels which is more efficient. Just plug it into the solar input on the rig which is a direct connection to the battery. The Victron controller reports via the Victron Bluetooth app as well.

              i don’t have a direct solar connection, unfortunately

                I just added a 200 W portable solar panel to my 2022 337RLS. I wired the RV and portable solar panels in series to the MPPT controller to maximize voltage (For PWM controllers connect the solar panels in parallel). Attached is the wiring diagram I made.

                  It sounds like some basic wiring is required. I'm assuming your batteries ar in the front compartment. If it were me, I would place the sidewall port ( ncitro recommendation) on the camp side of the front area (you'll have to cut a small hole in the side of your trailer....yikes!). Run positive from sidewall port to a shutoff switch, then from shutoff to battery positive terminal. Negative goes from sidewall port to negative battery terminal.

                    I just bought a Transcend 247BH and had a go-power suitcase solar panel. When we set the camp up I just wired the solar panel directly to my batteries. Just like I did on my old Jayco. Seem to work find. The rig came with 1-12v battery but will be replacing it with 2-6v batteries

                      Thank you, this is exactly what I was looking for, do you happen to have any photos?

                          The external connector looks like original equipment. Hard to see the wiring in the photo of the MPPT solar charge controller. Renogy has a lot of good information on controllers and wiring in parallel or series: Series vs Parallel Connections Explained | Renogy Solar

                              Chris, I have an 2021 model 303. You could cut the inside front wall near the battery disconnect switch, wire in the plug as shown above, then using an extension cable run the power chord out through the wiring bulkhead in the plastic tray on the trailing side of the basement. You could even instal a bulkhead on the leading side of the plastic tray. That way no holes in the side wall.
