my controller is on the "grid" side of the isolation barrier (when grid tied, else the isolation barrier is shunted)
so no need for all these isolaion devices. KISS principle.
Are you using a 50 Hz transforer after your LV H-bridge ?

Far from KISS there's no way I would want all my test gear or myself connected to the grid thank you :) I prefer to do my debugging strictly at earth potential hahaha

No its ferrite, the large trafo in the photo is just going to be added to the part of the test rig emulating solar panels.
I dont have an LV H-bridge, the H-bridge is connected to the grid.

I think in hindsite I have published way to much information here already for safety. Whilst I am an ardent DIY enthusiast I do it with knowlage having spent a lifetime as an electronics designer. I would not wish to attract the kind of copyists who I see on many forums requesting schematics to copy with little idea of what they are doing.

I would like to thank the contributors to this blog who have helped me with insightful sugestions to some of my problems and I hope I have provided some alternative ideas in responce.

High voltage high energy electronics are extremely dangerious and should only be undertaken by the significently experienced IMOP.

Yep, for that I use an isolation transformer, as a test setup.
