Hi Bill,
One of the largest benefits of the microinverter system, in my opinion, is the ability to monitor each module individually. It might seem like ~$500 is a lot for the Envoy but I think it is well worth it when you think about the 25 year warranty period and included ongoing monitoring. We’ve had enough Enphase failures that I would personally really want to be able to keep my eye on each micro individually. Just a thought, August *From:* RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] *On Behalf Of *frenergy *Sent:* Sunday, September 28, 2014 2:26 PM *To:* RE-wrenches *Subject:* [RE-wrenches] Metering CA wrenches, I'm trying to (for the sake of my monetarily impaired customers) figure out a less expensive way to meter/monitor small enphase systems. One of my local utilities will allow me to just use a remanufactured utility-grade meter (ala AEE) These meters are inexpensive, robust and accurate but only display total production. The Envoy retails for over $5 bills. Most of my customers are not interested in checking their PV system on the internet, well not after a couple weeks. I can't seem to find any requirement from PG&E other than in Section 5.1 of the guidebook: " All systems receiving an EPBB incentive must install a production meter accurate to +- 5% of actual system output...." which is pretty vague. plus the is no CSI incentive anymore. Anybody have a suggestion that is different from the remanu utility meter?....and possibly gives current wattage output, and is "approved" by PG&E interconnection? TIA Bill
