Good morning all 

Need some technical assistance 

Luxpower 5kw inverter with dyness 5kw battery 

All installed professionally with coc

I'm getting weird voltages when inverter is running from battery no grid 

Line to neutral 225v 

Line to earth 261v

Neutral to earth 40v

Can anyone help I have installed 3 of the same systems and only have this issue on one 

The place I purchased from is of no help whatsoever they suggest I join a whatsapp group 

Attached is some pics 

Hi, your installer did not install a Neutral Earth bonding relay, or the relay is not working. Now you have a floating Neutral.

afaik the sna5000 does not need the relay as it has it's own internal bonding. Perhaps there is a setting that enables or disables it?

 

Any update on this? I'm also having the same issue on my Luxpower SNA5000. What was the fix?

Email ... [email protected] attach some pics and they can advise u further 

I have noticed that via the installers login there is this option:

 

When I enquired with Luxpower local SA support via Whatsapp they said that I only need to set it to enabled if I do not have panels.
That does not make sense to me, although without a battery I cannot run my inverter in islanding mode so have not been able to do much in terms of testing.

 

@Mr 350 Has your issue been resolved? I assume you are not sure what was done / changed to resolve the issue?

Yes luxpower did resolve my issue.....requires about 5 days patience for reply 

Ive gone the NC contactor route already... connected to incomming grid.

let me check for this setting in the installer login
