Re: [AFMUG] Photovoltaic charge controllers and SNMP

+1 for the sitemonitor monitoring. The web interface ***of the charge controller*** is in no way protected. I would not trust it on a network even if I had it behind a firewall. Whoops. ryan On 5/10/16 11:03 AM, D. Ryan Spott wrote: Make sure you have the most recent firmware for the

Re: [AFMUG] Photovoltaic charge controllers and SNMP

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

Re: [AFMUG] Photovoltaic charge controllers and SNMP

Yeah, this is cool stuff, thanks Forest. I like the idea of pulling the data stream directly from the controller. Jesse DuPont Network

Re: [AFMUG] Photovoltaic charge controllers and SNMP

In relation to monitoring various charge controllers We've also got a new unit coming, hopefully shipping in the next 2-3 months or so (we've ordered enclosures, which is a good sign) Pictures are up on the web at http://monitoryourworld.com/. It's the top product picture. It's

Re: [AFMUG] Photovoltaic charge controllers and SNMP

We wire our solar controllers through the Tycon TPDIN. We graph voltages and current for the DC bus, batteries and solar panels separately in both the Dude and Cacti. Get Outlook for Android On Mon, May 9, 2016 at 2:15 PM -0700, "Eric Kuhnke" wrote:

How are you retrieving the data from the morningstar to feed into the program? http interface? 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

Re: [AFMUG] Photovoltaic charge controllers and SNMP

meh the packetflux uses ~1watt (actually .7watt)...i think i can spare a watt to monitor the system ;-) plus it has a relay and some other features that are useful at a solar site. http://store.packetflux.com/sitemonitor-base-unit-ii/

Re: [AFMUG] Photovoltaic charge controllers and SNMP

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

Any chance you could snmpwalk one starting from the root OID, numeric, and copy/paste the results back to the mailing list? I'm curious what it exposes. On Mon, May 9, 2016 at 2:22 PM, Sean Heskett wrote: > We use Morningstar tri-star controllers. They have a web interface

Re: [AFMUG] Photovoltaic charge controllers and SNMP

We use Morningstar tri-star controllers. They have a web interface and snmp support via an Ethernet connection. You can also hook up to the serial port a packetflux module designed for the Morningstar controllers. -Sean On Monday, May 9, 2016, Eric Kuhnke wrote: > Is
