[RE-wrenches] mechanical vs. electronic kwh meter

[Dana]

Never heard of this and we have run every system we have
installed "backwards" thru the  non-net meter to verify
operation and connection and no damage ever.

Hello,

 

I am now in a debate with the metering dept. of a local
utility. They don't want a PV system to be energized and
tested until a bidirectional electronic meter is installed.
They insist that an old plain Jane mechanical meter can be
damaged and is a safety concern if power is pushed through
it (its running backwards) to the grid. I have never heard
of, witnessed, or been told this by any utility or AHJ
inspector until now. Have any of you ever?

 

I don't know the reason for their paranoia. I assume that
many utility districts don't to this day install
bidirectional electronic meters. And rely on the original
mechanical meter to count backwards reliably and safely.
