Victron MultiPlus Compact 24V | 2000 VA | 50A - TRAIC EXPLODED ON POWER UP

Hello all!

I have had a problem with the "magic smoke" getting out of my unit.

  1. Connected the Tesla Battery Pack (reading 23.2v)
  2. Connected inline disconnect between the battery and MultiPlus Compact
  3. Turned disconnect on prior to powering on the unit and saw internal red light turn on
  4. Set the unit to "Charge Only"
  5. Turned on power to the unit

I have a video here (https://youtu.be/YfRcvtqxR9s) and have attached images of the setup. I did not have the "sense" cable connected to the battery unit; however, I did not think not having it connected would cause the unit to critically fail.

I did a voltage test on the battery module after this happened and it is still reading 23.2v. Thank you for any help and here is the series of images from my setup.


Prior to failing the colour LED sequence was: Green, Yellow, Green, Yellow, Off

That's obviously not good.
Send it back to your dealer an have it replaced under warranty.

Sounds good. Thank you for the help and I guess I will be calling Northern Arizona Wind & Sun to see how they want to handle this.

@WKirby Could the Tesla battery be doing this? I was told that they are not "really" supported. Just curious...


But I will say that Northern Arizona Wind & Sun has submitted the issue to Victron for review. I am also using 6 AWG wire if that matters.


I will be using 0 AWG in my next hookup.
