Inherited with our new to us MH a Steca Solsum 6.6 X solar charge controller.
Found a half an hour today to examine the setup which is in working order and came up with 2 items in the system that are questionable, and although spent a while looking can't find any operating instructions for this exact model.
The first is the wiring between the charge controller and leisure battery is around 5.5m long, and it's 1.5 mm2 in area .
I know this is too small a diameter for the potential 4.5 A output not to lose something between the controller and battery, but by how much would that be?
I guess that as the return earth cable is the same length and diameter, the loss is doubled?
Second part I don't know is wrong, but don't understand it. There is a short glass fuse fitted at the front of the controller, it's an electronics or household type with the value of 10A at 250V. Is this right for a 12/24V DC controller?
Thanks
