Excellent video! You even covered multiple ground scenarios which is something even a lot of electricians get wrong.

Totally Brilliant. 5 Stars. This video has viral potential from what I have seen on KZfaq and DYI channels. Should be mandatory in all high schools and electrical courses. Looking forward to grounding solar disconnect breaker box and inverter/battery for a off grid set up but the inverter is supplied with AC.🇨🇦

This complex topic was explained in a concise and user friendly way easy for the listener to understand

Fine video, thoughtfully presented. I would suggest also showing Ground protection on a real world system, and also touching on conductor sizing for eg PV grounding. Thank you for this very helpful vid.

Nice job

Super explanation! Please also comment on transformerless vs transformer based solar inverters and the various types of PV panels.

Thanks for the video. Are you saying that there should be a grounding system on the roof that covers the perimeter of the solar panel array, and that should be connected to its own copper rod in the ground? The frames of the panels themselves should then all be tied together and be presented to the earth terminal in the solar controllers or if using a solar inverter, to the inverter itself? I am completing a 40ft catamaran which has a 6kw solar panel array, two 10kw solar inverters, two 45kwh LiPO4 lithium battery banks and two 15kW electric outboard motors. I will be running the two hulls independent of each other, with 3kW of solar going to each solar inverter. I was thinking of doing four spike charge dissipators at the corners of the catamarans roof which would be linked together with 70mm2 cable. During weather that posed a risk of a lightening strike, I was going to then fit 4 removable large copper cables which would be attached to the spikes and draped into the water. None of this grounding would be attached to the frames of the solar panels, but would be to try to keep the charge of the localised sea area and the surrounding air above it, at an even voltage thereby reducing the risk of attracting a lightening strike. The cat is a solar cat so no mast to worry about. Does that solution sound likea good idea?

excellent video again! Do you do professional solar system installations or assist in inspecting the systems? or refer someone to install the system that I am buying? thanks a lot!

could you make a video or describe what to do for an off-grid solar PV + battery (not-grid-tied, no-grid) situation?

Good video, thank you. How would I ground a standalone system not connected to the main?

Excellent. Now, why do the PV installers not run a ground from the ground mount, via the wiring trench, to the ground rod which is going to be near the entrance panel/meter base?

thank you for this video I have know clear view

Would be nice to see a battery in the system.

Why would you ground a DC system to earth as the neutral is floating. Wouldn't it be wise to make a lightening rod system to attract unwanted lightening strikes to safely carry it to earth? Cars, trucks, motorhomes all are powered by a DC systems and are not earth grounded as well as boats. We have DC as well as AC aboard our boat and no earth ground.

Yeah this is extremely helpful, but how about isolated 12v solar setups that are not tied into a homes main panel. Does having grounding rods around panels help in a lightning strike? Im just setting up a couple batteries with a couple 100watt panels, for a back up during power loss, but not hooked into the house in any way.

What about a pure DC battery bank system with no inverters?

Hi, do you provide services like inspection of solar system for a fee?

Looks like a older spider man

Ok on the wiring diagram starting at 14:40 there are 2 box's with red arrows in them , 1 on the dc side and 1 on the ac side of the inverter. Are we just supposed to guess how things are wired inside these box's , do you assume we know how things are wired inside these box's. would it not be prudent to show us how things are wired inside these box's. I think if you showed use how things are wired inside these box's it would help us "to ensure safe and effective solar grounding" ???????
