Can the MPPT 250/100 VE.Can fail in such a way as to pass PV voltage to battery?

I understand it's non-isolated and the PV (-) and battery (-) are at the same potential. This begs the question:

Can the MPPT 250/100 VE.Can fail in such a way that that PV voltage could be passed directly to battery?

I have seen some pretty spectacular fails on the 250/100s and no, it does not pass the voltage down to the batteries.

They pretty much self sacrifice.
