The fuse from the panels is not the issue. The over discharge error is because the controller can't detect any voltage from the batteries.
If you disconnect the fuse from the panels (so controller can not output anything) and then hook a voltmeter to the controller output with the battery cables connected to them, do you show any voltage? If so, then the controller is probably the issue. If not, then there is an issue with the wiring.
Is your setup connecting direct the batteries or is there a battery disconnect in the path?
