William, There are some issues with putting the charge controller at the other end of the feeder: 1. The advantage of a higher voltage feeder is lost. 2. The voltage drop in the feeder will mess up the charge controller's absorption and float set points. Say there is only 1% drop in the deeper, that's 0.14 volt for a 12 volt system (2x for 24 or 4X for 48 volts). If the feeder loss is more ... You could raise the set points at the regulator to offset the feeder loss, but the loss in the feeder is not a constant. 3. The charge controllers are not NEMA 3 rated, they need to be inside.
