  1. This is actually a common issue with various PIs (2B, 3B+, 4, etc.):
  2. Hi Geoff Before I upgraded my firmware, I noticed the power balance setting slightly improves the situation: Then after upgrading the firmware as described in the topic below the error hasn't happened again. It seems the inverters try to squeeze less watts out of the MPPT but achieves more stability. My inverter brand is Full Circle Solar which is Voltronic. Are you also on firmware 71 82 or later? I also switched from ICC to solar assistant for monitoring, but I doubt that monitoring has an effect on inverter performance.
  3. I'm going to try the MQTT feature when I have time. I'm running the HASSIO version of home assistant with a tasmota sensors. Will post some screenshots of what I find.
  4. I've tried both. It's practically the same software. It's two partners that split up and each is now selling it separately. Since they split up, each have made their own changes to it.
  5. You can thank me for that part. I use to be a Centurion Solar customer. I noticed the app hanging every 1 - 3 days. I wrote a script to detect that it hangs and then restart it. I emailed the script on to Centurion Solar. I then saw my script is included when they sell new devices.
  6. Hi @Youda, I have a similar issue: I can read my Pylontech batteries via RS232/console. I can read other Lithium BMS batteries via RS485, but I can't read my Pylontechs via RS485, they simply don't respond. Did you ever manage to get a response from your Pylontechs on RS485?
  7. For those that are already using the RS485 port for battery connection, has anyone tried the RS232/Wifi port? The protocol document does seem to mention it, also the solarman wifi data logger connects via this port.
  8. The inverter reports SoC based on voltage and is designed for Lead not Lithium. Doesn't matter much as it doesn't do anything with SoC. All settings work on voltage. You mention it's charging. I assume the light is just flashing now and then. What is your bulk/float charge voltage setting?
  9. Sorry for spamming this topic, but everyone here seems very knowledgable on the infinisolar V range. In South Africa we are not allowed to feed power into the grid, but you still want to use the grid feed function of this inverter to power your own loads so that you are not limited to 5kw. Is there a way to limit the feed to grid so that it only feeds enough for your own loads? On other inverters there is usually an external energy meter to tell the inverter to limit export power. Perhaps via USB commands?
  10. @Bloubul7 Instead of using a Raspberry PI zero to read from the inverter, are you now considering connecting a Raspberry PI 4 via a USB to RS485 converter like the ones below? I assume the PI 4 then also runs home assistant where you show metrics/charts. If this is not your current plan. Do you see any issues with going this route? https://www.robotics.org.za/W17286?search=usb to rs485 https://www.robotics.org.za/RS485-MINI?search=usb to rs485
  11. Hi @JacquesVDM, thank you for the clarification. I'm interested in developing something similar for my setup (pylontechs + axpert parallel) and I'm familiar with reading data from these devices. Once you have something you are willing and happy to share please feel free to do so
  12. I see there is a big price and size difference between this inverter: https://voltronicpower.com/en-US/Product/Detail/InfiniSolar-2KW-5KW And these "V" range inverters where the V2 is the high voltage MPPT: https://voltronicpower.com/en-US/Product/Detail/InfiniSolar-V-II-1.5KW-2KW-3KW-5KW https://voltronicpower.com/en-US/Product/Detail/InfiniSolar-V-1K-5K Does anyone know the difference between the two ranges?
  13. Hi @perg67, which USB to serial adapter are you using? I think normal serial is 12V while others are 3.3V: https://electronics.stackexchange.com/questions/274287/what-is-the-difference-between-rs-232-and-ttl-uart
  14. What information is inport for you to see across all sites? What price site is acceptable?
  15. Thank you for sharing your results. Although I can see the inverters is having a hard time handling that specific problem scenario, my problem is fixed because the output voltage remain stable. I've created my own software that I will probably make available for free. It runs an embedded grafana which is what you see in the screenshots. It runs on a Pi and in future I will probably have a closed beta if you are interested.
