    Welcome to the Forums! 
    This thread has some ideas on where to look while you take the tour of your Tab.

    Why do I think it may be under the 3way frig/behind the wardrobe area?  I could be way off…

    I put our second one for the suitcase panels in the same place.  It requires expertise in Tab Yoga!

    Yes, it was moved here from its original location on the 400 when the three-way fridge option to replace the wardrobe locker was made.  Originally on the MPPT was under the bunk in the Alde space, which became the pump location. 

    Blue no 1 was original MPPT location (now the water pump area) and red no 2 is the current location, on some 2020 TaB400s it was on the otherdie of the bulkhead from its original location, behind the new under hanging locker drawer.

    Thanks all! I am also installing a 2nd MPPT and couldn’t find the original under the bed. Everything looked nice and neat in other posts and expected an easy install. Planning on putting a shunt in also, but things seem more complicated than they should be. Found a heavy duty lug connector area between outside storage and battery compartment, but I want to put the shunt in a location that is more accessible. Now the real question….
    can I simply tap into the battery wiring of the original MPPT or do I need to run a separate line from the 2nd MPPT to the battery? I don’t see lines from the primary MPPT to the battery, so I assume I only need to run a line to wherever the original lines go to.

    You should wire the second MPPT directly to the battery, with a 30-amp inline fuse.  

    The original MPPT is located close to where the solar panel wires come into the TaB, and it’s wires are just large enough for one MPPT load.  A better location for the second MPPT controller, is in the rear outside accessible storage compartment, which is close to the battery.  You can connect it to the two lug battery wiring block (which is connected to the battery). Then you can have either a SAE plug on a wire you can pull out through the storage locker door, or mount the SAE connector on the trailer side next to the door for a permanent installation.  

    If your TaB already has the SAE connector on the driver’s side, then just mount the MPPT controller near where SAE comes into the trailer, disconnect the wires going to the SAE plug (which are connected to the battery) and connect the wires to the battery side of the MPPT and wire the other connection to the SAE plug, and Bob’s your uncle...

    Thanks Denny, after I posted my question, I figured it out. Don’t know why I was making a mountain out of a molehill when the wires are already there.
