Just to round off this thread, got my immersun unit in place and has been happily working its thing.
Difference between this and the solarimmersion was +£200, so quite a bit dearer
But once it’s wired it self tests and sets up automatically and configured the CT clamp direction, so no fiddling about with that.
Control panel more user friendly with more features for setting the electricity earnings.
You do get more for your money, if you want the App you have to then buy another plug in unit, which didn’t impress me so didn’t bother.
Working well as I had hoped.
