Since all this discussion about the growatt 5000es has started, I was curious if there was a definite answer on the LV 6548 grounding.
This video from Dan Fitzpatrick kinda shows the issue that I assumed, switching to/from utility power seems to be a bit funky. I've read other threads where they say there is a ground fault when the inverter clicks over modes, but it clears within a minute or two.
I am mostly curious/confirming if:
1.) Sub/CL panel should *not* have neutral/ground bond (as expect) in bypass mode
2.) Sub/CL panel *needs* a N/G bond in non-bypass mode, as seems to be indicated by Dan's video
3.) I've read the inverter should automatically do #2 with an internal contactor?
Thanks!
