2-4 ga is better than 4-10 ga isn't it, as far as voltage loss etc? Not to mention the welding cable would be easier to work with than the UV rated MC4 cables I'd think..?
Depends on equipment. How many amps and what controller? Expansion plans?
You probably had a thread on it....
I pulled #10 MC4 wire through the strain relief, down the fridge vent, through the wall to the furnace, through the floor, across underneath, forward to the front compartment, through that wall and up to the cut off switch. Yes it took some time but not exactly difficult. Yes the wire is a bit stiff but that also helps it hold the position and push through any drilled holes. Smaller drill bit also. 7.5 amps, 90 volts DC.
To make pulling wire easier be sure to unroll the coil same as it was created. If you just pull off the side and straighten the resulting spring-coil you will add a bit of a twist to the wire and it will be more prone to kink.
