<p>Jason,</p>
<p> I'm so glad you brought this up, I'm having a very
similar issue backfeeding a utility (PG&E) meter that we
recently started backfeeding on a small commercial job. Somewhat
unique in that its 208/120 SINGLE phase (L-L-N). The inverters
are pushing about 3,000 KWhrs/month to the grid, way more than
typical July consumption at this site but their billing shows
modest consumption.</p>

for a utility meter to be programmed/wired backward? I have a
client on an Enphase system with production and consumption
monitoring, and the Enphase monitoring is showing solar
production exceeded consumption by 400 kWh for a billing
period. However, the meter is reading almost exactly the
opposite. It seems too coincidental.</div>

was billed (net usage of positive 400 kWh). </div>
