- Sunsynk 5kW Inverter after install done with Earth Neutral bond trough contactor because we don't want multiple earth bonds on the site creating ground loops.

Like! Thanks for sharing!
Should one not do a permanent Neutral Earth Bond?
Nice job.. So if you do not do and earth neutral bond that means when eskom is off and the inveter is running if I test a plug point for earth I will not get earth?
That is correct, and you will need an Earth neutral bond on the
Loadside loadside to make the earthleakage work while no grid
Thought the new installation manual show otherwise, not using relay but permanent earth neutral bond and then not using PE on LOAD side?
You are correct and I also saw that. It definitely shows that in the 8kw manual. We will change accordingly
@@jacqalas shows in 5kW Sunsynk and in Deye manual
Good vid. What pins are you using for the earth neutral bond
We are not using that for the bond anymore and we have a permanent Bond now. The pins that say live and neutral are used to switch a relay and you have to activate that in the menu by ticking the signal islanding mode block
@@jacqalas oh ok ; so the live and neutral energize the relay coil . So how and where do you bond the neutral and earth . Suppose that will be the output of the inverter ?

Lekker man, I am wondering what size cables I should use for AC input and output to inverter. I have a 5000w SunSynk. Since it can output max 10000w for a few seconds, would cables that can handle at least 10000w be required or only 5000w (23A)?
6mm would be sufficient. Cable won't get enough time to heat up trough a spike.
6mm is usually enough, but i put 6mm on output and 10mm on smart output /gen ort
It's illegal to do a permanent bond on the inverter side if you have one aready on the gridside.
Most important is to just make sure the inverter is safe for everyone and there is never power leaking anywhere.
Very nicely installed. Could you give details on the contactor used. Many thanks
We actually now do a permanent Earth neutral Bond and for that we remove the Earth wire from the output on the inverter. So we not using a contactor anymore on Sunsynk inverters.
@@jacqalas Is this for a full of grid application? If I may ask why did you do this? Just trying to learn?
@@AltF4Moments this is for backup power at a guest house next to a river during power outages. It keeps all the televisions and the internet on during this time. It also takes care of a few small fridges and all the lights at the premises
@@jacqalas Howzit man, why are some saying you MUST use a contactor and others are saying it should be permanantly bonded - with Deye and Sunsynk. There are so many confilcting stories, People are saying if its permantly bonded across Earth and Neutral on Load side the there is a floating Live, Neutral and Earth when Loadshedding happens - please help! thanks man.
@@FlyByR10T I know this is confusing but we tested it with a tester and the Earth neutral Bond is there when the grid falls away. The problem with the contactor is that they can fail and then you have unsafe installation
nice, can you earth be shared from mains board to inverter to battery
I'd rather not comment on that. In my opinion that would be the safest but in South Africa I don't know how long you can still Trust on the utility's ground. Whatever you do just make sure in the end you get zero volts between neutral and ground even when the inverter is in backup mode or the grid is back. Good luck with that and make sure to ask an electrician except if you are one just to double-check everything.
@@jacqalas thanks for the tip, with earth leakages moving to current devices and not having an earth tail , most just goes to spike, the earth leakage jus operates on current drop between live and neutral and not the sign of current on earth
Hi are you able to assist with a wiring diagram for the distribution board?
Electrician does that for us so no sorry.
@@jacqalas Hi, could you please give the contact details for the electrician who did this design?
Is the DC and AC split?!
Split like a banana!
Worrysome that you use a contactor.
You said the DBs were done by the electrician. Does that mean you are not an electrician and you did the inverter and battery?
I supplied the inverter and battery and assisted my electrician where they needed help and advise an yes the contactor is now changed to a permanent bond and the contactor now is used to power a light that turns the whole premises red to inform everyone that they are on battery power and must lower their usage accordingly.
