What wire size from solar panel to Victron Smart Solar MPPT 100/30?

[Time Keeper]

I'd like to have about 20' of wire so place this panel freely where I want when at camp. What gauge should this wire be going from the actual solar panel to the Victron MPPT? And should there be any size difference from the MPPT to the battery?

My cords like that are 10 gauge. My remote panels also use Anderson connectors. When you buy your wire make sure its at least automotive grade (primary wire). Stay away from anything labeled CCA (copper coated aluminum). If you shop Amazon, be very critical of what you buy.

My feed from my controller to battery is 8 gauge. A bit overkill but I'm capable of running all three of my panels at once if needed.

Here's a few Amazon links to compare. I'm not saying buy from them, its what I came up with quickly. I normally buy my wire from Waytec or Del City. For what your doing, the Silicone wire I linked, meets your needs perfectly.

Primary wire Most of my wiring is done with this grade of wire.
Silicone wire I make my cords out of this.
Copper Clad Aluminum "10 Gauge Stranded Flexible Copper Clad Aluminum CCA Primary Automotive Wire" Notice how they through in "Automotive Primary Wire" Stay away from this type. The amount of loss in this type of wire is huge.

Smritte, you always have great answers. You teach electronics or something correct?

Yea. Before I started teaching, I did automotive electrical for a living for almost 3 decades and a semiprofessional hobbyist my entire life. I tend to obsess over things that grab my attention and love to learn new things. For the most part, all my attention has been around anything off road/camping and everything related to it.
