My PV array is 4 x 100W panels. Two series strings combined in parallel to create a hybrid array. In order to parallelize them on my roof, the 2 ft connectors that come attached to the panels need extension. I bought some extenders and set it up, but I'm immediately aware of a potential problem. I only bought extenders for one of the sides of the parallel combination. Here's what I mean:
So, now one side of the cables feeding the positive side MC4 Branch Connector is 5 ` long ( the 2' panel cable plus a 3 foot extension) while the other is still two feet in length. In addition to the length difference, there's an additional connector on that longer side adding more resistance. It seems to me that this is a balancing problem, with one side of the positive cables having more resistance. But maybe this is corrected since the solution is mirrored on the negative side.
Do I need to extend the other sides to make everything even, or is it perhaps already balanced?
