The main reason to want to have the Enlighten system is warranty. Try to
get a replacement inverter if Enphase can't monitor the system over the
Internet. <br><br>

Great points and a little
education of others' feelings about, essentially how granular we need to
be in monitoring. <br>
<br>
I'm curious who is monitoring
the Enphase systems in the solar world, seriously. I know 95% of my
customers are more concerned about catching the bus or what's for dinner
than if PV #8 has bird crap on it. Do the folks at Enphase, through
Enlighten have some software that spots issues? I know I, as an
installer don't have time for it. My experience is the customer
notices their power bill was higher last month, they take a look at the
inverter and no green light...CALL BILL.<br>
<br>
Thanks folks for the resources
for meters, din rail too.<br>

<dd>I would not classify what we are doing in PV as SCADA.<br>
<dd> <br>
<dd>It is purely data acquisition at this point, and more commonly
referred to as DAS or a Data Acquisition System.<br>
<dd>SCADA by its definition entails a two way path of both receiving data
and being able to send control signals, usually from a big picture
program, monitoring dozens of data points.<br>

<dd>The 2nd problem with the Envoy besides cost is that it isn't always
reliable. Communication through power lines is not a
new or fresh idea, and has Always been problematic. Once you
install something you are expected to make it work, and that can be a
nightmare on say an 8 module system that keeps losing communication to
one or two modules. I've had this exact case, and confirmed
multiple times that each micro was working, but the Envoy had other
ideas.<br>
<dd>This rush to mega data acquisition makes sense for larger PPA
systems, but can just add tons of call backs and the resulting financial
losses and frustrations for small systems.<br>
<dd>I've spent as much time messing with SCADA, as I have with the entire
install itself; now that's ridiculous. This isn't new either:
I had SCADA systems back in the 90s, that had great promise, but
ultimately were extremely hard to implement, and the customer never used
after anyway......<br>
<dd>The question is: <br>
<dd>What does the customer really need to operate the system vs.
"bells and whistles".....<br><br>

<dd>Hi Bill,<br>
<dd> <br>
<dd>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.<br>
<dd> <br>
<dd>Just a thought, August<br>

<dd> 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. <br>
<dd> <br>
<dd> 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.<br>
<dd> <br>
<dd> 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?<br>
<dd> <br>
<dd>TIA<br>
