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.
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
Are you using a 50 Hz transforer after your LV H-bridge ?
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.
