I like the DIY Tester plug, creative! I normally just stick the tester leads into a plug. In the end the important part is the RCD disconnecting live if current leaks to Eath, this is what you should be testing, both in island mode and grid mode. High value resistor and let some current leak from L to E.
Awesome video! Thank you. This has answered a lot of questions. I have a SAJ H1 and I kept getting a ISO error meaning earth fault, due to a non earth neutral bond. Did a small test and hey presto it works. It’s actually quite sad/scary that my installer didn’t know what to do and’s eventually “abandoned” me and my issues.
Hi @svengebert8690 , I am very happy you found it useful. Not only does it cause unnecessary tripping of the earth leakage, flickering lights etc but it is also dangerous!!
Thanks for the information. Lots to consider if one is just installing a Sunsynk inverter. Since I've put the whole house on the Essentials/UPS output, using a relay becomes pretty much redundant since there is no separation between circuits as far as neutral and earth is concerned, i.e. the original main board is not split in the normal sense. Hence I opted to use a permanent E-N bond.
Hi @kevinrtres It seems that there has finally been some clarity as to what the correct way is to do Earth/Neutral bonding on the Hybrid inverters and you will need to switch to a relay to be compliant. ecasa.co.za/technical/neutral-earth-bonding-clarified/
@@SolarIntegrationsThank you! This is greatly appreciated. Will have to go through all the googly gook attempts to describe what should happen - they really could have just used well-drawn pictures to clarify!
Hi, Thanks so much for your content! I have searched the internet far and wide and you have so far provided best info on this. However I need some advise.. on an isolated farm with no eskom grid infrastructure the farmer uses a very old generator 3kw. The elect. That installed the system have a floating neutral geni then running only N&L wire to the home db which does have an ECLB. Although it wont work because no earth. The generator is about 30m away with no ground electrode it is just standing on the ground. I am busy helping install a 5kw inverter kit for him. It is a 5kw synapse 5.0KRM+ inverter(cheapy) with a 5kwh hubble am-2 and solar panels. The unit is a permanent bond on the ac output. I dont see any way to disconnect it. The manual states that you are able to put grid or generator on ac input.. i want to set it up so that the inverter is the primary supply. Then if weather is not great and battery dies then he should be able to start the generator which feeds only into the inverter ac input and then the inverter needs to charge battery as well supply some power to the home. The inverter has 5 ac connection terminals for the ac output it is LN and bonded E. Bonded to the ac out N. Then the ac input only has the L&N but right next to these are the other 3 terminals. It seems almost as if they wanted you to use the same earth connection for the ac input.. Now i am batteling to figure out if i should have geni bonded and fed into inverter or unbonded and utilizing the same earth on the geni. This seems really confusing. Perhaps you can advise? Fyi i feel the current generator setup without earth is dangerour very dangerous. I would want to change this and make it safe. I have an electrical background but not in house wiring. Ps your accent sounds like you from PE..
Hi @francoisswanepoel544 , unfortunately I am not an electrician and I can't give you any advice about that except that maybe you could try posting your question on the powerforum.co.za. There are a lot of very smart people there and if you explain your problem clearly & properly there is usually someone around there that will be able to give you good advice. I prefer not to mess around with my grid power too much as it can be rather dangerous and prefer to leave it up to the professionals.
Amazing explication, i have a 8Kw Deye inverter and i have installed a contactor to make the Neutral-earth bond controlled by the deye ATS RELÉ but i have a doubt, wich neutral should i connect to the contactor, the grid/home load neutral or the critical load neutral?
Hi @makunan , I am not 100% sure. I would recommend speaking to a qualified electrician who can advise or alternatively speak to the guys on the Powerforum.co.za or energytalk.co.za who would be able to advise.
Some clarity finally on the correct way to establish the Earth/Neutral bond ecasa.co.za/technical/neutral-earth-bonding-clarified/

Thanks @HeinzMeulke, I wish I could say the plug was my idea but someone on the Powerforum suggested it and I thought it was genius.
Very helpful video, especially the plug tester suggestion-thanks for taking the time to make this.
Thanks @paulfraser5957, I am glad it was helpful!

I had to teach the guy who did the installation what was cooking - he had no clue!
