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.

Any one who have any ide what it cant be?
If course there are 4 hours drive to the site, so any ide for remote checks are appreciated.

There are a CCGX on site, with full remote access from home.

@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.
