Make sure you have the most recent firmware for the charge controllers.
There is a memory leak in older (5 years+) versions that would knock out
monitoring. Charging would happen like normal but details about that
charging were just static numbers.
The new firmware now only leaks enough to freak out every 2 years or so.
Just bounce the charge controller during your yearly maintenance and you
should be good.
+10000 for the sitemonitor monitoring. The web interface is in no way
protected. I would not trust it on a network even if I had it behind a
firewall.

How are you retrieving the data from the morningstar to feed into the

I'm fine with using curl, sed, regex in a shell script to graph
arbitrary data from things that present more information via a
non-SNMP interface... Been doing that for a while with external
sources like weather data, I-5 traffic, etc.

I actually have a few C programs that can be used to query any
values you want from a Morningstar with ethernet. I use them to
feed MRTG with the actual voltages and currents through my
Morningstars. One less piece of hardware and one less cable to
deal with and one less voltage vampire on my solar sites...

if you hook up a packetflux to the serial port than you can get
everything you could ever want to monitor via SNMP. The built

is pretty limited.
here's a screenshot of the packetflux web interface, all these
values
can be obtained via SNMP.

Any chance you could snmpwalk one starting from the root OID,
numeric, and copy/paste the results back to the mailing

curious what it exposes.

We use Morningstar tri-star controllers. They have a web

connection. You can
also hook up to the serial port a packetflux module

the Morningstar controllers.

Is there anything new on the market in the last 2
years or
so that speaks SNMP over IP and Ethernet?
Specifically I'm trying to figure out how to integrate
OpenNMS and Cacti with OIDs for integer values
like charging
amperage, input current from PV, current battery
string
voltage, etc. Temperature monitoring would be nice
too.
