It is just electric and inductance parasitic fields in the inverter that give that voltage, so that is why there isn't a measurable current with a pincer.
On both of my battery systems I use the DIY monitors I have made based on Arduinos. There are video series about the LiPo battery monitor and about the AC Powerwall controller including upgrades. I do npt monitor on cell level. You would need a smart BMS for that...
Yes, it might cause a spark if your N had a higher voltage on it :) But that would be normal and intended as it is only during equilization. Similar as of discharging a capacitor.
@@olvano I saw it on Grid-N already too. There it mostly happens if your house is somewhere at the end of the line, with a lot of users, and the TN-C supply gets a bit dirty. That's why at some point, alternative Earthing has to be installed. It can of course easily be with TT-Systems, as there your Earth and the utility N is not connected, but there it as well should not be. So if you are adding a ground rod and connect it to the Grid Neutral, make sure you are not in a TT-System! But anyways, after you connect an Earthing rod, always check if a current is flowing
@@olvano that topic was shown in the 3rd video about Grid/Off-Grid mixed setups in all Earthing-Systems. I know, Earthing can be a bit confusing, as it is very individual to the property and its grid connection itself.
Ground faults between inverter and initial distribution until the RCD, would be covered by the inverters short circuit or internal ground fault detection only. Thats why the bolding link is important too, as it would provide a short circuit path. The inverter would then shut down with a fault message. Ground faults at later stages are covered by the RCD, which typically trip at 30mA fault current.

Great video my friend and excellent explanations.
Could I ask what device you are using to remotely monitor your plant?

if u hookup the ground wire to the neutral ,them put the a 5 feet grounding rod in the earth .when attaching does it spark and it suppose too? 🤔🤔🤔

it the grid neutral is it normal to .the connection must be solid or will burn off u think?

i think we need a next Grounding video 😥😥

If there is any current you would have a ground fault and the system should trip or at least sound an alarm.
