Neurio Monitoring Performance Issue

Hello,

I have a recently installed Neurio device with the Tesla solar panel solution (2 inverters) that I’m having strange performance issues with on the monitoring side. Before the Neurio was commissioned (PTO) the app reported solar performance without issue. I didn’t think this fit with some of the other threads, but I could be wrong on that. My device runs for a few hours then the communication seems to freeze, drop, or get stuck between the Neurio and the inverter (Tesla). The Neurio is only tied to one device that Tesla says is correct. However, the only way to recover is to bounce the inverted, rebooting the Neurio does not resolve the issue. Once that is done everything runs fine for a few hours. See graph with flat area indicating the issue.

Wondering if anyone else has seen what looks to me like a communication issue between the neurio or possibly an inverter issue (Tesla). I was thinking about asking Tesla to move the Site Meter connection to the other device to test.

Looks like I figured it out so I'll recap for others that might have the same issue(s) down the road. Must not be many yet with the Neurio device and Tesla inverters without Powerwall's. I made three changes that seemed to resolve multiple issues I was having with the reporting.
  1. The CTs were installed incorrectly so I made sure there were both pointing up around the bus where my service came into the panel. The are actually marked with that information 🙂.
  2. I swapped the phases at the Neurio device - Ports one and two. I did this because I had some strange readings between my home and grid data and the solar was showing constant flow to the grid. Really messed up and totally unreliable data.
  3. I have two inverters and Tesla tried to connect the Neurio to both of them. I went into the web interface on the inverter not tied to the neurio and deleted the site information. Not sure if this was doing anything or not but the crashing/WiFi Dropping stopped and the configuration information didn't need to be there anyway.
This isn't for everyone and going into the panel is scary/dangerous business but I couldn't wait two months for a service call. It was just the reporting so everything with the utility and the meters was registering just fine. I'll still have Tesla come out but at least for now all looks fine.

I'm waiting for PTO on my Tesla solar panel install (Neurio, no PW, 1 Tesla inverter) so will be keeping this info handy when things get turned on.

I know there used to be, or still are, standalone Neurio devices that can be purchased. The one that Tesla installed seems to be a Tesla-specific model since the box it came in showed a model number of "W2-Tesla". I was curious where the Neurio data is going to.

My understanding, and based on your #3 above, is that data goes from Neurio => Tesla inverter to track consumption, instead of Neurio => internet, right? What did the "site information" setting look like in the inverter web interface? The Neurio seems to only transmits it's wifi signal for a few minutes after powering up so I'm wondering how the ongoing comms are handled.

thumbs up for fixing. 120V has never killed me! now i've never been hit by 240V, and that is why we have a two wire 240V solution. just wear gloves and be carful to only use one hand as much as possible. always test neutrals, they are often hot! yes, i always work with live wires, don't do what i do!

Yes it goes directly to my smaller inverter then through my wifi to Tesla. The inverter just seems to be a pass through but the site information tab has a Short ID number and the Neurio Serial number entered. I just saved the information and selected remove from Wifi. If you only have one inverter you wont need to worry about this one. Someone on this forum posted a nice diagram that shows some details.
