2 of 3 MPPT regulators died

The other day a costumer of mine noticed that the PW power have decreased significantly.
They system are 2-3 years old, so stuff should not start to fail already.
I checked the VRM logg and noticed the following:

Note that regulator 1 voltage reading looks normal, but number 2 and 3 are more square and strange - they are all feed from the same battery.

It cant be the DC fuse to the battery?? or? but they read the voltage in the night.

@Jimmy Henningsson

I would worry about 1 more than 2 or 3

The voltage readings on that ones are terrible. They should all match. So a bad connect most likely. The custom widget is useful BTW.
