Change controller AFTER the ZAMP outlet?

Hi all!  I recently set up a portable solar panel that connects to a charge controller that connects to my ZAMP outlet (big THANKS to Galway Girl for the post on how to do it, and for answering a lot of my questions!).  But could I install my charge controller AFTER the ZAMP outlet (so it would be under ones on the beds inside the Ollie) but before the 20 AMP fuse, or must the charge controller be installed between the solar panels and the ZAMP outlet?  Thanks.

No worries, put it inside if you like, but you then lose the ability to use your portable panel with other trailers or to charge your truck battery, for example, if it goes flat when you are exploring elsewhere.. What brand and type controller do you have? You might want to consider installing a high quality MPPT unit under the bed, and keep the older one as your emergency spare or for other applications as I mentioned above.

As long as you use good quick disconnects, you can easily switch from one setup to the other.

Just what I wanted to hear, John!  Thanks!

I have a Renogy 20A Voyager, which as your know, is a PWM charge controller.  I bought it because it was a cheap way to dip my feet in the 'solar waters', and I knew it would fit in the waterproof box I bought (same as Galway Girls), and it wasn't too expensive....but I know it would be better to have a MPPT one.  So I totally agree with your advice....I will keep the Renogy for emergencies, but buy a nice MPPT one to put under the bed (that has bluetooth so I can monitor it with my phone).

Keep in mind ventilation requirements, look at the installation manual for those specs, for example vertical or horizontal, and distance between objects. The Victron units prefer to be vertical with a few inches of top and bottom clearance, the Redarc ones are more forgiving, some can even be mounted under the trailer frame.
