Title: Re: [RE-wrenches] kwh meters

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? Thank you.

If not, that’s the reason its not working.

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.     Gary Easton NABCEP Certified Solar PV NABCEP Certified Solar Thermal APPALACHIAN RENEWABLE POWER LTD.
