Hello

 

recently installed the Axpert VM IM 3.6KW (has the round LED screen thing with RGB colours)

 

it worked fine for a couple of days but then today when LS hit the inverter died, went there and pulled the fuse and returned it then it worked.

 

I Am not sure what would have caused this. Would and overlaod or at least exceeding the max DC discharge cause the DC to be disconnected but then the inverter still worked as there was Grid. 

 

there is no solar connected either.

 

I am a bit confused on this one and don't know Axperts too well

Do you mean an Axpert VM IV 3.6 kW?

Is the battery size small for the inverter size perhaps?

What battery are you using?

Yes sorry that one! 

And using 2x 12V 230AH. Lithium batteries 

 

I set the discharge to 50Amps as was only for security reasons but then they were using the kettle.

 

I just want to try make sure I know what's happened as for it to not happen again and also further my knowledge:)

Forgot to say lithium

It may well be that you exceeded the discharge amps. Depends on how big your kettle is, a 2kw kettle on a 24V system will require just over 80A from the battery. Lower voltage systems require more current to provide the same load.

Yes I believe so too, but I am not sure if this inevrter would then disconnect itself as of over discharge but then when grid returns work per normal in a bypass manner then ? 

Basically I would think after overload it would shutdown completely and not even work just on grid and would require a restart. 

Hoping it is due to the overload and the inevrter is not faulty. 

 

Check your manual, there is a setting for "auto restart when overload occurs" (06), which is set to disabled by default. If you turn that on it should restart itself next time.

I would suggest turning up your discharge amps again, you will need 150A to use the full 3.6kw the inverter can deliver... what was it set to before?

I doubt the inverter is faulty, it is most likely working as it is supposed to with the current settings.

I am off grid and haven't overloaded my inverter, so I am not exactly sure how it behaves with grid. I would expect if the discharge amps are exceeded it should still work if grid was available and set to auto restart.

Ah yes, I am sure I changed it to restart but perhaps I missed that one and did the tempreture one. 

Yea ya I will up it to 150A once I get the fuse (stock is a bit issue ), It was not supposed to power the kettle as the guards would take liberty but It is nice if they can make a cup at 2AM load shed haha.

 

I will check the restart setting as I didn't have the Manuel when there to check. 

 

Thanks all
