This is not a work related question, rather a technical question on my new PV system.
I'm on Duke Energy in Greenville SC. The solar installer and his electrician installed a 4.25 kW (DC) system which has been in operation for about 3 weeks. After city inspection, Duke installed a new meter about 2 weeks ago, single meter which is in my service line, thus without direct knowledge of solar production.
The meter, an Itron Sentinel, sequentially displays 8 values, date, time, 2 in kWh, 2 in kW, and 2 in kVArh. My system uses Enphase micro-inverters, and the monitoring software give me their (Enphase) production information. I'm trying to correlate the information.
As of November 21 evening, Duke's meter gave:
210 kWh
97 kWh
1.35 kW
2.58 kW
31 kVArh
22 kVArh
Enphase tells me I have generated about 190 kWh since the meter was installed. My historic consumption in winter months is around 400-500 kWh. I cannot understand how the 210 kWh can have been determined, UNLESS my consumption has been about double the norm (210+190). I can see how I might have pushed 97 kWh net back, genertaing power for about 9 hours/day, with the average for those 9 hours most of the days over consumption for those hours.
Do any of you know what Duke has programmed these meters to display?
Thanks!
