The Pentametric is great for on site data collection and monitoring. It
can handle up to 3 shunts for anything you want, and has a simple
Windows interface that's good. You then can use their Excel templates
to graph out all the data you want.

Another monitoring question I have for wrenches. Does anyone have any
recommendations for a standalone, versatile data logging device, that I
could leave on sites with no internet connection, and get trends
(battery voltage, SOC, battery currents etc) over time? I like to show
people that they are using more power than they think.
Thanks

First, Outback does have a solution: the Flexnet and Mate 3 stuff;
Outback's stuff is pricey though. They're also a mess to wire IMHO.
Here's 2 others to consider: Pentametric from Bogart Engineering,
and Midnite Solar.
Midnite Solar's monitoring is free when you buy their
controllers. They already come with an Ethernet port too. (unlike
Outback's)
ALso, Midnite has the new Gizmo Jr. which is a single wire shunt
monitor connection, and they should have full State of Charge
monitoring capability soon for it on their monitoring website:
mymidnite.com <http://mymidnite.com> (also free).
The Pentametric is my long time go to meter, and it has a full
Ethernet setup, but they don't have a website like Mymidnite.com,
so you have to access the Pentametric remotely through the local
network. That gets into static DNS addresses, etc.; all that IP
stuff I'm not well versed at.
I've successfully used both monitoring systems.
Also, don't just look at daily production; for off grid, you need
battery state of charge.

Hi Wrenches,
I am evaluating remote monitoring solutions for an off-grid
project and wanted to get any feedback people were willing to
share. I see my three main choices as Outback, SMA Sunny Island,
or an XW system, the first two of which I have a good bit of
experience with.
It looks like the only good remote options for Outback are 3^rd
party which I couldn't get much info on, despite emails to the
manufacturers. Anyone have any experience with GreenHouse Gas
and Electric dataloggers?
A Sunny Island with a Webbox and Sunny Portal seems the most
straightforward, but doesn't have real-time data.
I stumbled upon the Connext Combox on the Schneider site and it
looks like a great product, but I am a little wary. What
comments I did find out about it online weren't very favorable.
And it looks like setting it up for remote access is not very
straightforward.
Thanks for any thoughts/experiences!
