I am finishing a project of adding solar power to a treehouse. My receptacle tester indicates that there is an open ground. I drove an 8 foot grounding rod into the ground near the treehouse. I then connected a 6 AWG wire to the ground connection in the solar combiner box. Where should the grounding wire be connected to?

I've found some cheap inverters don't even have a ground connection to the ground pin and others put 150K resistor which is enough to drain off static charge. Your detector is testing to see if there is a connection at the power source between neutral and ground, NOT IF THERE IS A GROUNG. Some inverters have a floating neutral and that tester will never read correctly. -
lol....another instance where there is a confusion of "ground" and "dirt". The NEC could fix this sad state of terminology but.......NO!Comment

Take a few minutes and google some electrical terms....start with ground, grounded and grounding....then move on to earth, earthed and earthing.....if your mind is still into it....then look up grounded conductor vs ungrounded conductor. That will get you started.
You will graduate when you know the difference between an EGC and a GEC.Last edited by DanS26; 07-30-2023, 04:48 PM.Comment

Your tester is showing that there is no neutral ground bond in the circuit. This is the low impedance ground system that will clear a fault (trip a breaker). A ground rod (earth) is the high impedance ground which will bleed off static electricity in the system and energy from a nearby lightning strike. Not much can be done to prevent a direct lightning strike. Ground rods are much more important for grid tied applications because the grid is a liability.Comment

Looking at big transmission towers, note some light, uninsulated
wires well above the main power carriers (with big insulators).
Those top wires hope to take the lightning instead of the
transmission conductors.
It is possible to use this method to discourage direct lightning
strikes on other things like solar panels. Build a kind of
Faraday Cage around them. Rarely done. Bruce RoeComment

I have to laugh when even Holt drove a ground rod and connected it to a washing machine. Thats not a ground!Comment

I did not sign up for insults.
Which part of junior member do you not understand? I was just looking for advice.Last edited by oregonchoate; 08-01-2023, 11:17 AM.Comment

Who go you think insulted you ?
I saw what looks to me like mostly pretty good information which is, to my experience, more than you'll get for free most anyplace else.
I'd suggest you consider just saying thank you for the information and act on it as you see fit.
Welcome to the forum of few(er) illusions.
While you're at it, I'd suggest dropping the attitude of an entitled child, grow up and learn that not everyone who tells you what you may not like is trying to insult you.Comment
