At the 1:15 you mentioned that most PV systems would have the ground fault protection within the inverter. When you say most, I assume that means that having ground fault protection in the inverter isn't a requirement for UL listing? For example, a VERY popular inverter for the DIY crowd is the Voltronic based LV 6548, but from what I can find, even the latest variant of it, the EG5 6500EX does not have built in ground-fault protection, yet it has a TUV / UL certification. I assume that means that not having built in ground-fault protection isn't a requirement for getting an inverter certified?
So how do you find the fault? First find what string is causing issue then take multimeter and test each negative and positive of each panel? By disconnecting them from the string? Make sure to cover panels so you don’t get shocked too. Trying to figure out this now any fast reply very apprecated
So does it mean to hook up all metal parts of the solar system to the ground of the house ground and put a 1A fuse from ground to the negative side of the solar wiring? My inverter has a ground post on the back of the unit, so I just hook the ground post to the house receptacle ground.
Does the DC always have its own earth electrode ? Could the AC be bonded to this also ? Is the purpose of the fuse to stop fire ? as the system keeps running ok
Great Video! This wasn't what I was actually looking for but I found it to be excellent content. @4:30, You hit on my 'Pet Peeve' about people discussing electricity and issues with it. The old 'The power takes the path of least resistance!'... As you said it does but it takes all paths. Some not so knowledgeable people actually believe that to be true or fact. I have had to explain that if that statement was accurate, components in parallel wouldn't work, current would only flow through the component with the lower Ohm reading! Thank you for not repeating that old erroneous statement that way too many believe. Again, Nice video. Ya'll Take Care and be safe, John PS: Would you know of a good video in relation to testing a solar panel for ground leakage with a multimeter? I have seen a few that are just showing and trying to sell you a specialized product that they sell. Thanks

Brilliant explanation. Usually, separate grounding is usually recommended. Should the inverter, the PV should still be grounded
Thank you very much. Very clear explanation!
Excellent explanation. Well done.

Thanks for the great info, can we use the grounding rod of the ac system? (As shown in a picture in your oldest video)

Great content and explained really well

Clarifying video, thanks!
What happens if u check everything and go to test it and it pop up relay test code
Thank you
Nice Information Sir!
