    Solaredge monitoring issue with two inverters after system expansion

    Recently I expanded my solaredge system. The original setup has performed flawlessly, but I wanted to add additional capacity with another inverter (we have a 2nd EV now). We also wanted backup capabilities with the great Texas freeze of 2021 and power outage as still a fresh memory. I choose to go with partial home backup with the addition of a sub-panel. All of the new panels aren't in yet, but enough to start running it are.

    Anyway, the original setup was an HD-Wave 11400, it operated for about 18 months and generated about 29 MWh. I also had an independent import/export solaredge meter and the data matched up with our smart utility meter. OG Inverter and meter communicated on RS485 and the inverter was hard wired for ethernet. The expansion added a second energy hub 7600 inverter and the back up interface. An LG battery will be here shortly, but is not currently in the mix. The backup interface's import/export meter is being used with external CT's, the energy hub is now set up as the leader and communicates via RS485 with the backup interface and the OG inverter using the differing outputs provided within the hub. Standalone meter has been removed. Both inverters are hard wired for ethernet and communicating.

    Everything is activated, communicating outbound, and producing as expected. The issue is two fold and, I suspect, related. My site historical data in monitoring interface was 'lost' AND the output from both inverters is not being shown added together. I put that the OG data was lost in quotes because it is still there under the layout tool associated with the original inverter, you can see daily, weekly, yearly and total data populated under physical and logical layout display. The total production at my site is only showing as the portion from the leader energy hub inverter. This single inverter data is what is shown in the daily graphs, total daily output, etc. The import/export meter appears to be working correctly as my daily chart shows usage flat-lining when my total output exceeds usage and I'm not getting the typical split into four energy buckets (production, self consumption, and import). It still logs the OG inverter output somewhere as you can see daily, weekly, etc data since the changeover within the layout tool only.

    Any ideas how to correct this? I submitted a ticket to solaredge support last week and haven't heard back. I feel like I must be missing some simple setting somewhere.

    Here you can see the two inverters don't add up for the site output:

    Here you can see what I'm talking about with my daily data, I am exporting more than I am producing since export is both inverters and production is only reading as the lead inverter:

    I suspect it's an issue on their end.
    I just put my solar edge system online 4 days ago (7.2KW ) and like you have a revenue grade meter in the inverter. My production numbers seem correct (within expectations) yet on their site my monthly production is shown to be 2.03 Megawatts. However lifetime is more realistic at 196 kilowatts. Daily is correct until midnight then gets those crazy megawatt numbers.
    I also generated a repair ticket and am still waiting to hear.

      Solaredge was able to correct this. You can see in the logical system diagram above a device labeled the production meter and it needed to be disabled. Doing this enabled both inverters to talk to the monitoring platform directly and restored my site historical data. All my data output is correct now for this site.

      So, that was more or less their response and the correction. Which they handled from their end. I do believe i could have disabled it in the monitoring platform as well. I speculate that the production meter is a virtual device in the newer inverter and the older inverter just didn't know to talk to it. It couldn't have been the physical meter in the new inverter as I'm not actually using that one, there are no CTs connected. The meter being used in my system is in the backup interface.

      Now I'm thinking it would be nice to meter my backup panel and my total usage separately. I have two meters built in after all... I might tinker on this.
