Pylontech US3000 not displayed in the device list

Good Day,

I am having the same issue that was reported in the "US3000 not shown on venus" thread. In my case I have a Multiplus-II GX (5k), thus it is a little more complicated to swap out and I'm hoping to resolve this without having to got that route.

I've read the aforementioned thread as well as other other related threads and I am pretty sure that I've got everything set correctly. Here are all the steps I have taken:

  1. Upgraded the firmware
  2. Set "CAN-bus profile: CAN-bus BMS (500 kbit/s)" (note that it was already set)
  3. Tried a different CAN-bus cable between the battery and the inverter (I have 2) and also tried flipping it around.
  4. Powered on and off the batteries
  5. Tried a single battery.
  6. Tried switching around the CAN terminator and the cable

Below are pictures and screen captures of my installation. Any help would be greatly appreaciated.

Thank You,

Ryan

Hi @Ryan Sheidow

https://www.victronenergy.com/live/battery_compatibility:can-bus_bms-cable#selecting_the_right_cable

The supplied cable does not work with a GX. Check the article above.

The links between the units are fine though.

Hi @Alexandra

Are you certain it is the case that I am using the wrong cable? The cables I have are from this kit: https://autosolar.es/accesorios-baterias/cables-pylontech-lv-bateria-inversor. It specifically says "un cable de comunicaciones de 3 metros con crimpado para comunicaciones CAN" I think the translation is fairly obvious. This is the correct cable, right?

Thank You,

Ryan

Hi @Ryan Sheidow

I have used Pylontech on a few systems now. Always either use the type A from Victron or make up our own, the pi outs are given in the article. Feel free to check them on the cable you have purchased. The one from that kit does not have the correct pin outs for the GX side.
