Is it possible to monitor my output using this site?

Questions
#1

Hi, complete newbie here. I thought I’d ask if what I’m trying to do is even possible before I put too much effort into this. I have registered and added my system.

I have a 4kw system on my home. The company that installed my system no longer supports the monitoring website. Here is a link to where I used to go to monitor the power generation:
http://spv.solarpowerinc.net/SiteList.aspx

However, I can access the unit that used to send the information to the website from my LAN. Below is a screenshot:

I attempts to update the website every 5 minutes

Will it be possible to use this website to monitor my power generation?

Thanks

Thanks for your reply. Just to be clear, the plug has already been pulled on the website. I’m trying to find out if I can use my existing hardware output to monitor my power generation.
Is there a program or app I can use to access the output from my current power generation monitoring hardware that is accessible on my local area network?
I’m not a computer programmer so it would need to be relatively straight forward to use.

What is the make and model of your inverter?

#5

My inverter is a Yes! Solar Inc. model ES 4000 (4kw). Yes! solar solutions was affiliated with SPI Solar and I believe they just re-branded their products. Yes! solar solutions is no longer in business. I think SPI Solar moved to China. I don’t think they do business in the US any more.
The monitoring system is separate from the inverter. It has a battery powered inductive sending unit that wirelessly transmits to a receiver box that is connected to my LAN.
The monitoring unit is a Yes! energy series Monitoring Manager -900.
Thanks

I couldn’t find any useful docco online re the inverter or energy monitor. Do you have anything apart from the screenshot you provided (which is pretty useless for monitoring purposes)? Maybe some photos would help.

Failing that, something like a neurio or sense might be a better option for you: https://theblueadapter.com/sense-vs-neurio/

One reason (apart from all their other excellent features, websites, etc) is that these units can be used to measure consumption vs production as well.

Here is a picture of the receiver:

The FCC ID (OUR9XSTREAM) on both the transmitter and receiver leads me to believe the guts are 9XStream by MaxStream.
The MAC ID gets me to JK Microsystems.
I can post more pictures but I’m new so I can only post one at a time.
Let me know if you think more pictures would be useful.
Thanks

  1. Capture the data format sent by the device to solarpowerinc.net using wireshark etc
  2. Post samples here.
  3. If the data is usable in (2) then reroute requests from solarpowerinc.net to pvoutput.org, see https://stackoverflow.com/questions/3266483/editing-hosts-file-to-redirect-url
  4. We would need to develop something to accept the data.
#9

I’ll do this once I figure out what I need to do in Wireshark.
Thanks

#10

Also, I do know it is trying to transmit to the website in XML format.
See screenshot below (I tried to post this in the first post but couldn’t because I’m too new on the forum).

I used a display filter to capture the data
I get a list like the one shown below:

Is there specific information you’d like me to provide?

Thanks

#12

Basically useless as solarpowerinc.net site does not respond, and therefore there is no conversation to capture.

It’d need a web server somewhere to impersonate solarpowerinc, which might trigger the monitor to try to push its data.

I’m set up to do that, but unfortunately on the opposite side of the planet… just buy a neurio, lol…

#13

As per @MrFusion comment, looks like a deadend, since the device requires a response from solarpowerinc.net site before it can send the actual data.

#14

If you sent me the transmitter & receiver pair I’d be happy to have a look, but I suspect the shipping back and forth would be 50% of the cost of an alternative solution anyway…

#15

I suspect your right about the shipping costs.
It does have some communication ports on it so it looks like the software could be accessed:
