<DIV><FONT size=2 face=Arial>Electronic meters always work in favor of the
utility company. Mechanical meters can be ratcheted 1-way or unratcheted
bi-directional. Bi-directional meters can be calibrated accurately. Meters are
the utility's cash registers. Businesses get very angry if you touch
or even look closely at their cash registers. The recession has resulted in
more business closings and home foreclosures which
means fewer utility meters and less revenue so utility
companies are watching their meters very closely. Utility workers are also
concerned about bi-directional electricity flow safety. LADWP's revised
solar program says if the PV system meter shows 10 hours or more PV production
before the net-meter is placed, then the customer forfeits the rebate
and the contractor can be taken off the approved installers list. It
often takes Southern California Edison 6 to 8 weeks place a meter on a PV
system. LADWP is even slower. Yet new non-PV services get meters/cash
registers placed usually within 3 days. Expect strong pushback if you try
to fight your electric utility's meter policy. You're better off making friends
so that they place meters on your jobs quickly.</FONT></DIV>

<P class=MsoNormal>Hello,<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>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?<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>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. <o:p></o:p></P>
