This is my Setup

Not to scale but basically what I have done,,, short run from the mppt to the battery
Only thing I'll change is the way I hook up the panel using those MC4 connectors
instead of a 50 amp anderson plug, Bummer as I need to change all my panels
80 watt, 20 watt and a 10 watt,plus my new one 120 watt
@ Bob did you have yours screwed onto a board or something
maybe screw it in a low tupper ware dish with some vent holes

I'm not 100% sure those Redarc's are a full MPPT controller, could well be but they are certainly a good quality unit.

Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.
Very, very rare to find a good MPPT below a couple of hunjy. Good name brand will be $300 and up
As a point of interest the 25 and 40 Amp jobbies in the BCDC series are quoted as MPPT by Redarc but the SRP series wasn't AFAIK
Depends on the guts but a big MPPT Controller will take 60 to 150 Volt panel input give or take.
I 'think' they can get the costs down of the MPPT if they limit the Panel Voltage and it's interesting that Redarc quote a max panel input of 30 odd volts
30 volts is the normal limit for a PV controller ergo those 10 and 20 amp redarc stand alone jobbies may be MPPT but personally I am not 100% sure.
Best way would be to check with Redarc but either way you know you are getting a good controller

@ ET my MC4 connectors have arrived, do you them together or alternate them
As in on the Panel do i use f and f or f and m, I dont see how it would make
much difference.
