MultiPlus II often doesn't turn on on the first attempt via Cerbo GX (Touch or VRM)

Hi everyone,

I’m experiencing a strange issue with my Victron system and I’m wondering if anyone else has seen this.

My setup consists of:

  • Cerbo GX

  • GX Touch

  • MultiPlus II

The issue is that turning the MultiPlus II on is unreliable. Whether I use the GX Touch locally or the VRM Portal, it’s quite common that the inverter doesn’t turn on on the first attempt.

Typically, this is what happens:

  1. I press On.

  2. Nothing happens, the inverter doesn’t start.

  3. I press On again a few seconds later.

  4. The inverter then starts normally.

This doesn’t happen every single time, but it happens often enough that I’ve noticed it as a recurring issue.

Since the behavior is identical from both the local GX Touch and VRM, I don’t think it’s related to my internet connection or VRM itself.

Has anyone experienced something similar? Is this a known Cerbo GX / VE.Bus communication issue, or could it indicate a hardware or firmware problem?

PS. everything is up to date.

Any suggestions on what to check would be greatly appreciated. Thanks!

For replication or troubleshooting purposes can you state your actual firmware versions.

There is 4 or 5 second delay in mine before it’s starts inverting, using a local browser.
