The 3-gang combiner box is pretty simple. Not taking anything away from it, as it is very good. But I don't think there is much to warranty there, and if there is it can't really be impacted by using breakers from another company vs Midnite fuses. Fuses are not really meant to allow you to manually turn a flow on and off. That's the main reason I prefer breakers. You can take a string off-line and do some work, then put it back on line pretty easily. You can do this over and over with breakers, but with fuses... Not so much.
