A string of panels in parallel. O.K.?
Feeder pairs from each panel running to a wire "manifold". Those two wires run to the controller.
Direct freakout copper touching copper short in a pair of feeder wires.
All of the panels will then feed that short in the two feeder wires. The feeder wires are smaller in AWG. O.K.?
On an RV system with it's LIMITED NUMBER of panels (Don't give a damn how many are bolted to the roof plus a tow trailer on behind)...
If those two feeder wires burn, you undersized the gauge of the feeder wires or do not know how to run a balanced manifold wire from all feeder wires to the controller. A two foot long 12 gauge wire can carry EIGHTY AMPS without burning. Been there, done that, got the tee shirt and secret whistle.
