Everyone will recognise the simple Dinkler-Thor differential axis vectoring setup here. The problem is that I can’t rotate past 27 degrees without the inverter fluctuating and losing lock. Can anyone spot my mistake? I feel like I’m missing something really easy.

    Are you using fluxshielded cables? In a setup like this your QF ratio can become too high without them.

      I am, but they are cheap ones from Aliexpress. I’ll have to get the mu metal sheet out and see if it helps.

        I use cheap ones all the time without issues. They are good enough. Of course it’s worth testing them using a Thor inverter. Maybe you have a bad one.

        Check if you have plugged them in with the correct polarity vector. Proper labeling and tidiness can really help here.

        If it’s not the cables check the Dinkle oil levels of your inverter.

    The whiteboard in the background shows an inverter configured for passive resonant signal filtering, but it looks like you have the inverter wired through a pre-amp matrix, which would default to active filtering. This will certainly cause instabilities beyond 27 degrees or so.

      Yes! I think that’s it! The 63rd wire from the right is plainly going to the matrix. Thanks.
