Is the bar on the right directly bolted to the enclosure, or is it isolated? Can't tell by picture.Good point. These are from a few years ago. 100A breaker behind the flap. I've been told there's a neutral-ground bond in the non-homeowner section that is above the terminal blocks.

Not the meter base. But the panel below it.So to be perfectly clear, the N/G bond should be at the meter base at my pole and every other panel in the system should be not bonded; regardless of whether there is 3 or 4 conductors running to that panel.
There should be an EGC (Equipment Grounding Conductor) ran between all equipment.Do I have to also run a ground cable to a separate grounding rod from the inverter?
Correct1. There are 3 cables running from the inverter AC out L-N-G so I thought that grounding the panel would automatically ground the inverter as inverter and panel are bonded.
All metal frames, supports, raceways, and enclosues should be connected (grounded/bonded) to the grounding system.2. I also have an array of solar panels that I use to charge the batteries and last week when I was cleaning them I got shocked. They are not bonded/grounded. Do I have to ground them?
They are not bonded/grounded.
I'm confused by these two statements.They are connected so I thought they are bonded automatically?
Yes3. Does bonding N-G at the electrical panel mean get a wire and connect neutral and ground?
CorrectI thought neutral is the current carrying path and ground is only current carrying path in case there is a fault,
Only for fault current.but if I connect them does that make ground the current carrying path as well?
Maybe I misunderstood. But I thought that you didn't have any other power sources (utility), other than the inverter.Also,
4. The inverter has AC charging capability as well, so If I bond N-G and connect the AC charging, that will create 2 N-G bonds. Wouldn't that be very bad?
If there is already an electrical system in the house. That changes everything.(could be thought of the main panel as I don't have any other panel)
Bolted and bonded.Is the bar on the right directly bolted to the enclosure, or is it isolated? Can't tell by picture.
You need to start your own thread.Good point. These are from a few years ago. 100A breaker behind the flap. I've been told there's a neutral-ground bond in the non-homeowner section that is above the terminal blocks.

Wow, I was only half paying attention this morning. I did not realize this either.I just realized that there are two people asking about two different systems, in this thread.
This is getting confusing, trying to keep track.
First and foremost. I cannot thank you enough. What I meant by saying the panels are connect is that I have a total of 12 solar panels and I connect them 6 in series with 2 string parallels.Correct
All metal frames, supports, raceways, and enclosues should be connected (grounded/bonded) to the grounding system.
I'm confused by these two statements.
Yes
Or install the provided (with the panel) green bonding screw.
Correct
Only for fault current.
The primary purpose of the grounding system is to provide a low impedance (resistance) path back to the source. So that faults can be cleared quickly, before anyone can get hurt.
The N/G bond provides this path.
My inverter is hybrid and allows me to charge from solar AND grid together. I don’t use grid at all but I can if I want to. If I bond my system then when I connect to grid, if I want to use grid + solar, then I’ll have two bonding correct?Maybe I misunderstood. But I thought that you didn't have any other power sources (utility), other than the inverter.
If there is already an electrical system in the house. That changes everything.
You already have an exciting grounding system. And everything new should be connected to it.
There should only be one grounding system. And only one N/G bond per system.
Bonding and grounding are pretty much the same thing.First and foremost. I cannot thank you enough. What I meant by saying the panels are connect is that I have a total of 12 solar panels and I connect them 6 in series with 2 string parallels.
1. I thought that means the panels are already bonded? But I got shocked while cleaning them. So maybe it’s because I don’t have a ground? Do I need to connect all panel frames together and run a wire from that to a ground rod?
2. The inverter isn’t grounded but connected to panels, both electrical panel and solar panels and the electrical panel is grounded. Do I need to ground the inverter?
If you have grid. That is your first means of disconnect. And the location of the ground rod/s and the N/G bond.My inverter is hybrid and allows me to charge from solar AND grid together. I don’t use grid at all but I can if I want to. If I bond my system then when I connect to grid, if I want to use grid + solar, then I’ll have two bonding correct?
So to be perfectly clear, the N/G bond should be at the meter base at my pole and every other panel in the system should be not bonded; regardless of whether there is 3 or 4 conductors running to that panel.
Mine doesn't have that option.Not sure if the menu options are the same as the ASF, if they are you might try changing setting option 63.
The inverter has AC charging capability as well, so If I bond N-G and connect the AC charging, that will create 2 N-G bonds. Wouldn't that be very bad?
Might want to reach out to SRNE. The contact info is on their website.Mine doesn't have that option.
