<DIV><FONT size=2 face=Arial>Chris' email motivated me to buy a low-cost,
easy-to-install monitoring system for residential and small commercial PV
systems. I sent RFQs to vendors asking for a monitoring system for my PV
systems, a SunnyBoy 240VAC PV system, and an
oldie-but-goodie Trace 120VAC PV system. See <A

not contact me.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Daron at locusenergy.com replied quickly. He was
very supportive, quickly answered questions, and gave us a training
webinar. Price for one system is reasonable: </FONT><FONT size=2
face=Arial>$509 for 5 years of generation monitoring, data hosting, and
performance hardware, plus $40 for California rebate program automated
reporting, plus $130 to monitor electric consumption. Daron did a good
job explaining Locus, but I needed 2 systems and didn't want to spend over
$1,000.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Charlie at egauge.net also replied quickly. Their
residential eGauge system to monitor the Grid, PV system #1 and #2 costs
$760, It includes the eGauge main unit, homeplug communication adapter and 5
CT's (2 CTs for the main utility feeds - one on each leg), 1 CT for
the SunnyBoy system and 2 CTs for the Trace system. Better price, but still
higher than I wanted to spend.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Robin at powersave.us (Envi) answered my phone
and email questions quickly. Their price was much lower so I bought
their hardware. $237 for 1<FONT size=2 face=Arial> Envi monitor with
</FONT><FONT size=2 face=Arial>1 transmitter and 2 CTs for PV system
#1, plus </FONT><FONT size=2 face=Arial>$79 for 1 transmitter with 2 CTs for
PV system #2, plus $12 for the USB cable, plus $17 </FONT><FONT size=2
face=Arial>for shipping.</FONT></FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Powersave shipped the equipment promptly,
but it took me a few days to get around to installing the
hardware. The Envi monitor is in our office next to my
computer. Installing the transmitter and CT on the Trace/battery PV system was
easy. The Trace inverter is in the garage next to our office but not away
from our electric service panel. You only
need one CT to monitor a 120VAC PV system's
output.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The SunnyBoy inverter is next to the
electric service panel. </FONT><FONT size=2 face=Arial>Grid power wiring
into the service panel is behind the clamped and sealed utility
meter. I did not want to break the utility seal to open that section
of the panel so I am not monitoring the grid. Besides, monitoring the
grid with a net metered PV system only tells what the
utility kWh meter measures. Inside our 200A service panel, t</FONT><FONT
size=2 face=Arial>here is just barely enough space for the transmitter.
The CTs are big, but I was able to squeeze them into the panel, replace
the breaker cover, and close the panel door.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Loading the USB cable driver was easy, but I
had trouble getting the computer to see the 3rd party monitoring
software. So I used the "C2 Terminal" free software to make sure my
computer was seeing the Envi meter. I still could not get any of the
monitoring software to work because the instructions were not intuitive or
simple enough for me to understand.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Tony at <A

instructions a few days ago. Today I had some time to muddle my way
through downloading, logging in, registering, etc. and am up and running. I am
still learning how to use his software.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Chris at currentcost.com is has been emailing to
help me use their software. I'll give it a try.</FONT></DIV>

<DIV><FONT size=2 face=Arial>Robin at powersave.us recommends Techtoniq. I'll
give it a try too.</FONT></DIV>

<DIV><FONT size=2 face=Arial>When I first talked to Robin at powersave.us, I

I’m looking for suggestions for a low cost DAS system for home/small
commercial use. It just seems to be such a useful basic tool to verify
performance other than just the Kwh meter. I’d like to add this to all of
our clients quotes and projects. Looking for the basics like module
temperature and irradiance and it would be nice if it would tie into the
existing inverters DAS like an Enphase, Fronius or SMA to name a few since
they already have inverter and PV in/output information. Or is Fat Spaniel
and Helitronics my only options otherwise? Thanks for the help ahead of
time.<o:p></o:p></SPAN></FONT></P>
