The 12-S approach in the Solar Pro article only works with 120V
inverter systems. I am facing a similar issue with our first XW system,
which was chosen for this application because it's the only GTWB
120/240V single inverter unit. We also currently have a REC program as
well as net metering. How can I make this work?<br>
Thank you.<br>

reason its not working. Here’s an article you can refer to:<br>

style="font-size: 10pt;"> I am using an analog GE kwh meter on an
outback system with battery backup to a protected loads panel. The AC
in to the inverter is attached to the bottom of one leg of the meter
and the AC out of the inverter is connected to the top of the other
leg. This should give me an accurate record of just the production from
the system. The idea is that the AC IN that will power the protected
loads panel at night will come in the bottom of one leg and turn the
meter backwards then exit through the top of the meter going forward
thus cancelling those kwh. out. I have a neutral hooked to the meter
because I am using it to record 120V but I am not getting accurate
readings with this configuration. Any suggestions on metering in this
case? I need a utility grade kwh meter. <br>
