I have a small system with 3 arrays of 3 340W panels each. Each array is handled by an epever mppt controller.
I was check on my SOC and I noticed I was lower than I expected. A quick check of the displays showed that array 3 was not supplying any charge. I have an inline fuse on each array, and the panels are wired in series. I checked the fuse and it looked like it had gotten very hot, the casing was deformed and I expected the fuse to be blown.
But it wasn't. I took the fuse assembly apart and put it back together and its working fine again.
I don't know what actually happened but I suspect that the contract between the fuse and holder developed some resistance and then heated up. I ordered a new fuse holder to replace that one, but don't really know what else I could check or do to determine if I have an ongoing problem.
