Installing Solar Panels

[gerdathome]

I am in the process of installing 2 solar panels 100 watt and 75 watt on the roof of my motorhome using 12/2 AWG from the panels to the charge controller.There is a run of 10' from the panels to the fridge vent and then another 10 from the fridge vent to the charge controller.
From the charge controller back to the fridge vent 10' again and 6' down to the base of the fridge.
Now my question is this; the instruction with the charge controller recommend to either hard wire to the batteries , in my case 12' to the back of the coach from the fridge vent OR tie in to the 12 volt supply to the fridge. The fridge tie in would of course be the easiest way of doing it but I am not so sure if it is indeed the the best way to go.The fridge 12 volt feed appears to be only a 16 gauge wire and only serves the electronics on the 2way Dometic (recalled)
Below the fridge is the furnace and there I could tie into a 14 gauge wire and I would like to find out if this wire would be heavy enough to provide the charging currant the panels are able to produce
Thanks for any suggestion you can offer.

Re; Solar panel wiring;

Unless things have changed, the positive and negative wires MUST go directly from controller to batteries. I'm on my 4th rig with after market solar panels on roof. Great investment toward more independence..

Also, use #10 wire wherever possible, #8 is even better.

You should be able to snake wiring along inside top of bays.

Any more info needed , please ask.
