[RE-wrenches] Metering

[August Goers]

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

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
