[RE-wrenches] Neutral run to critical loads sub-panel

Friends:



I found a grid-tie battery-backup system with a 120/240 VAC critical loads
sub-panel that has no neutral run to it.  All of the 120 VAC loads have
their neutrals land in the meter panel.



I have always felt instinctively that the neutrals should land in the
breaker panel that feeds the circuit.  I have looked through the NEC to
find a passage that spells this out but I can seem to find one.



Is this a code requirement?  Is this recommended practice?



Thanks in advance.
