Auxiliary solar

[carpenter]

Does anyone know how many watts i can add to the system via the auxiliary solar port on the street side of the trailer? I have a 400 watt panel set up for my anker solar generator. I am curious if I could just use a charge controller in line and hook into the system? Or are the wires not rated for that much current? 2022 elite 2 with 400 watt roof solar and 360ah lithium batteries. Thanks in advance for any info.

I have a Zamp port on the street side of my 2021 model near the battery box.   It’s rated for 20A max, but is equipped with a 10A blade fuse inside the trailer, which is a good match for my 140W portable Zamp panels.    I have 340W panels on the roof.   I’m not sure what the 2022 models have for side ports.

You can safely put a maximum of 200 watts into the auxiliary Zamp solar port.  It is polarity wired for a Zamp solar controller which is opposite of some controllers, so verify polarity of your panel and controller before plugging it in.  Polarity reversing adapters are available for the Zamp port if needed.  Your 400 watt panel would need a 30/40 amp controller, larger wiring, and a 30-40 amp fuse.  Check panel rating plate and ask google to be sure.

In 2023 (I assume it was the same in 2022) I purchased the optional 230-watt Zamp portable panel from Oliver with the trailer to add to my two 200W panels on the roof.  I think 2023 was the last year they offered this panel and I believe Zamp moved toward smaller panels.  The 230W suitcase is a bit of a beast to lug around, so I don't use it all the time.  Of course, this plugs into the side port that you mention.  Interestingly, because you can direct the portable panel toward the sun, it will often supply as many watts as the two roof top panels combined.
