The panels themselves doesn't matter as the connectors don't change.
When connecting the panel array to the Controller....
If you have an MPPT controller the choice is yours.
If you DO NOT have an MPPT controller they should be in parallel and the same rating as the system IE 12 volt system then 12 volt panels etc.
The 'default' would be a parallel wired connection
Be aware that 90% of the Controllers claiming to be MPPT are not.
MPPT controllers can operate on panel voltages significantly above system and are essentially a DC/DC converter.

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.
I already have a "MPPT" controller 30 amp all fitted into a clear box and ventilated.
As you and Cuppa I think said a while back not a tru reg but it does its job,
not feeling too flash Atm so will take some pics to show you and sort out the other MC4 connections.
So parallel it is.
looks like I'll need those combo style MC4 connectors 2 to 1
are these the ones I require for the back of the folding panels ??
I prefer the branch connectors that have a bit of cable rather than the moulded ones as they are a tad more forgiving in how the cables run but no biggee.
If it is a fully portable setup...
I would have put MC4 connectors on the "solar" cable to the Controller but not a major issue
and
Anderson variants on the "battery" cable
If the Reg is permanently mounted I would hard wire the "battery" cable from Controller to Battery terminals
The CMTP02 is not a MPPT Controller so you must hook your panels up in parallel

Thanks for that so a bit of soldering to do in the next few days,
I'll prep it all untill the branch leads arrive,
I'll also change the 50amp to the panel to MC4 as well
04 ST 3lt auto, not enough Mods to keep me happy, but getting there
Uuummmmm... be aware that Controller can get pretty hot.
If it hasn't get any airflow and/or a decent heat sink all the smoke will get out.
If the smoke gets out it will stop working and its a real bitch trying to shove the smoke back in.
You can get natty little vents that you can cut and fit to those enclosures

@ ET,Cuppa Ive had this and my 80 watt panel connected to a small 18 ah battery,[deep cycle]
All it has been running is a car radio and one led strip light, Ive been playing with all my panels
and cant for the life in me get the red lights to shine on that "MPPT" controller.
Can you put up a link to some thing that will last, I believe its US already.
Ive tried on my 20 watt and 80 watt panel ,,,no lights so Im assuming its dead,,, yes
Is this link ok for what I want??
Hook up the battery first.
What is the voltage on the battery terminals?
Now, hook up the panel
What is teh voltage on the battery terminals?
What is the voltage on the panel terminals?
