Solar disconnect line load

[dm9289]

I seen solar at a house today and had a question about the disconnect let me give you some details below

EMT coming off of roof from panels
Connects into combiner
AC output from combiner goes to line side of fused disconnect (lugs shielded plastic)
Wire coming from Utility power panel (hot tapped on line side before main) is on load side of outdoor solar disconnect. Lugs not shielded on load side so always hot even if you shut off disconnect or main panel.

Is this done commonly?
This was a major Solar company?
Or is there a special disconnect that should be used for this purpose?

Thanks in advance

The disconnect was installed backwards, the utility side should be the line side, as you concluded. That's the only way to make it safe to change fuses when the disconnect is open. The grid-tie inverter will automatically deenergize its output when it loses the grid reference.

What I see often is two disconnects close to each other with the load sides common to both in conduit.
When you shut off both, you know you are down.

Unless you're talking about two disconnects on each side of an inverter, that's a waste of a disconnect.
