Solar reg question

[Bob]

What I've decided to do is buy a 6" x 4" x 2" project box from Jaycar with a clear lid.
Into that I'll mount the MPPT regulator with 2 x 50 amp anderson plugs bolted to opposite side to the box.
Nice and compact IMO.
As for the panel from the junction box on the back of the panel I'll run 5mtrs of 6mm sqrd fig 8 wire which I
take it should be ok over 5 mtrs, I'll terminate that with another 50 amp anderson plug,
I can then plug it via an anderson from my AUX battery and into my battery box the same way.
If anyone sees something wrong or why it wouldnt work ,happy to hear you

I was thinking of putting my Redarc Solar Regulator in a similar Project Box with a clear Lid however I am concerned that it will get quite Hot inside the Box.

Does anyone have any ideas about the Heat

PS
Just checked the Manual for the Redarc Regulator and it operates up to 55 Degrees C and then swithes itself off.
