Is the E-Guage a revenue rated meter, acceptable for selling S-RECs?

<dd>You can also use a couple of rebuilt meters from Hialeah Meter
company that read both ways. On the AC IN, the power that is sold to and
purchased from the grid will add / subtract to let you know the amount
you sold or bought. The meter to the protected loads panel will
register one way to let you know how much power was consumed there.
If you sold more power than you purchased, you can add that to the
protected loads panel production. If you purchased more, subtract
that to find your PV production.<br><br>

<dd>Great explanation gary. I was thinking that between the AC1 and
breaker in the main panel was the right place but wasn't sure.
Thanks for the help.<br><br>

<dd>Manually-read legacy utility meters, in many cases, are set up to
accumulate current flow in either direction as kWh consumed. This was
done because dishonest people would turn the meter upside down for part
of the month, and then put it back normal before the meter-reader showed
up.<br><br>
<dd>My electric service has a bi-directional "smart" utility
meter that presents a cyclic display of kWh delivered (code 20) and
received (code 57).<br><br>
<dd>For my GTBB system, I use a GE KV2c bi-directional meter between the
XW AC1 conductors and the grid interactive back-fed PV breaker. This
provides a separate register for the kWh "bought" and the kWh
"sold" from the XW's perspective. <br><br>
<dd>The XW inverter AC output feeds a protected loads panel, which in my
case contains everything except the electric oven and the electric dryer.
My 3-ton AC unit runs off the XW inverter under grid-up, but is switched
off via a contactor when in grid-down. I have an autostart 6kW Generac
EcoGen connected to the XW AC2 for back-up in event of an extended grid
outage.<br>
<br>
<dd>The KV2c "bought" register accumulates the kWh consumed
when the XW is in AC Pass-Thru mode or grid supplement mode (PV kW not
adequate to deliver load demand). The KV2c "sold" register
accumulates the kWh delivered by the XW to the main service panel. Some
of these kWs power my 240V loads if they are active.<br>

<dd>Is the objective to measure all of the energy produced or only that
which is delivered to the grid? To measure the energy sold to the grid,
the meter goes between the XW and the grid, but it must be an
electronically detented meter that only records energy flow in one
direction.<br><br>

<dd>I would like to here some thoughts on monitoring the production a XW
in grid tie with battery backup mode. I normally use the Sunny Island for
my grid tie with battery backup systems and am considering going with the
XW on my next one. Just wondering where in the system one would
wire the AC PV Production meter to best represent the amount of power
sold to the grid. We have performance based incentives around here
that require metering of the power going back to the grid. With the
SI systems this is easily accomplished by putting the required meter
after the sunny boy before going to the critical loads panel. Any
ideas about how to accomplish this with the DC coupled XW system? Your
thoughts would be greatly appreciated. <br><br>
