Ohhh fail on the inverter test

[@doinsngoins]

Interesting....

Is see , a ground rod outside

Hmmm.

I have my cabin inverter ground bonded on a 6 foot copper coated steel ground rod, along with the circuit panel, and my back up generator. All systems are for 240vac since I run 120v split phase to my breakers. Now, my van and RV systems both have solar with 120vac inverters, and because they are both mobile units, there cannot be an earth ground. The RV had a backup generator, no earth ground. (bond). Both have been in service for 17 and 14 years, consecutive, without a single problem. Someone once told me I needed to earth ground/bond my turbine pole. Wow! So I'm supposed to place a lightning rod next to my cabin in a remote desert environment? I've dealt with electricity since 1965 in the U.S. and yes, I've been bitten a number of times, but I am still here, because I take most precautions. My point is, there are many out there, and I'm not saying the guy who instructed you is one, but there are many out there who think they are the only ones who are correct. Don't listen to every joker on social media, research it yourself. I'm not saying ignore him. Just saying, check out his claims. The fact that your meter shows no ground/bond at the inverter, but shows everything OK through the power strip is proof that something isn't kosher.

Thank you for your comment G Bear. I did do a lot of research for weeks as i did not understand earth bonding. Watched lots of videos, Looked at all the comments, Researched google, A chap had his safety certificate refused as his 240v plug sockets had a earth fault. He did the earth bonding. Then the chap who did his safety certificate come back and passed his safety certificate. I watched some videos on 18th Edition UK Electric Regulations to find out more about earth bonding.

You have earth bond for faults because the mains income from the grid is referenced to ground, meaning any fault can return to the power source and trip a safety device, so the power wont go through a person that is also refenced to the ground. The inverter is not referenced to ground. But I think you device has linked the neutral to earth to get the same affect. I'm not sure if that's a good idea, just my two penny's worth.

Thank you for your comment.

These things are supposed to supply plug in loads only and are typically configured for IT (the earth terminal on the case if even present can be staked to the ground) operation (even when connected to the mains for charging since this appears to have a mains inlet for charging on it) and in several countries by law no earthing system at all. I class operation is perfectly safe as is. In order for a person to be shocked (or worse) a double fault must be present. Please do not listen to random people on the internet telling you to form a N/E link on these things but if you absolutely must you absolutely should be using an RCD downstream of the N/E link that will permanently (until manually turned back on) interrupt supply. If the person that told you to do this was ukelectricalsystems, which it appears to be the case, that guy is an idiot and I say that completely unreservedly. He has absolutely no idea about electrical in the UK let alone other parts of the world. In reality you shouldn't be taking advice from me either, beyond the sentence below. If you have any concerns regarding an earthing system for your inverter employ an actual licenced electrician to check the device for correct isolation (there are proper testing procedures in the Britt Standard) and advise you what is actually necessary to give you a safe configuration.
