Re: [RE-wrenches] VFX produces no output with no error

[Hugh Piggott]

Hi All,

Just to wrap this one up I can report that the problem was in the control board 
in this instance, and having replaced this board it is now working again.  
Thanks for all who helped with advice, especially Jay and Kris.

cheers
Hugh

Re: [RE-wrenches] VFX produces no output with no error

[Hugh Piggott]

hi Everyone, and thanks for the support.

I took it apart and it is producing good sine wave up to the AC board but there 
is a black relay that is failing to close and it turns out that there is a 
light on the control board showing it is not even trying to close this relay, 
so that is why we are not seeing output at the terminals.  I propose to fit a 
new control board and hope that works.

This will be the second time I have been inside this inverter (since 2006) and 
maybe the fourth or fifth time I have replaced a board in a FX.  They are easy 
to work on, but my experience has been they do seem to need it.

Re: [RE-wrenches] VFX produces no output with no error

[Ray]

We had one last year with a bad relay, the customer had been charging a 
Tesla EV through it (pass through from the grid) and smoked the relay.  
It was pretty obvious, the clear relay cover was all covered on the 
inside with burnt relay bits and smoke coating.

I have an Outback VFX that I used for my own home from
2006-2018.  It’s a 50Hz 240V unit, but similar otherwise to any
other 48V VFX.  It was working well when disconnected.  I needed
to replace the inverter system for other reasons.

I installed this for a neighbour recently on his 48V system, and
it apparently worked when I left the building.

Now it’s not working.  When “off” it shows a warning for
temperatures sensor - fair enough I did not install one.  Maybe
when it gets connected to a generator it will be found a sensor. 
This is the only error or fault with a yes.

When “on” it makes a reassuring buzz and both lights come up
green and there is no error or warning in the Mate.  Just one
problem - no output.

Another weird thing.  I go to the status menu and check meters
 STATUS/FX/METER output voltage and it says “4V”.  So it _knows_
that it is not working but it appears to have no qualms or
misgivings about this state of affairs.  NO error, no warning,
two green lights.

I tried rebooting with the battery fuse.  I tried resetting to
factory defaults.  No joy.

I suppose I will take it to pieces and try to figure out a
hardware failure but I wonder if anyone has seen this and can
give me a clue?

Hugh,
   I have one at my guest cabin doing the same thing except that the meter
on the mate says I have 119 vac but nothing at the AC Out terminal.  I
think Kent might be right that it may be the AC output relay.  It is odd
though that there is no error message in your case.  This inverter had been
tortured by the last tenants of the cabin with bad generators.  I was
actually going to go up there and check it out some more as it is warm
today. No heat in the cabin.

Re: [RE-wrenches] VFX produces no output with no error

[Kirpal]

HughTypically the temp Sense warning is not related to an external temp
sensor, rather an internal temperature sensor.  The Outback inverters
typically will run normally even with this temp sensor not working.  I
believe it is related to temperature of one of the boards and relates to
turning the cooling fan on if present - normally it is not related to a
battery temp sensor which is what I got the impression you understood it to
be. However, typically this will show up as a red blinking error light
which signifies a warning instead of a solid red error light during which
the inverter may stop working.

Hugh,

I've seen these symptoms before. The problem was a failed output relay 
on the ac board.

Hi Wrenches,

I wonder if anyone can tell me what is happening here?

I have an Outback VFX that I used for my own home from 2006-2018.  It’s a 50Hz 
240V unit, but similar otherwise to any other 48V VFX.  It was working well 
when disconnected.  I needed to replace the inverter system for other reasons.

I installed this for a neighbour recently on his 48V system, and it apparently 
worked when I left the building.

Now it’s not working.  When “off” it shows a warning for temperatures sensor - 
fair enough I did not install one.  Maybe when it gets connected to a generator 
it will be found a sensor.  This is the only error or fault with a yes.

When “on” it makes a reassuring buzz and both lights come up green and there is 
no error or warning in the Mate.  Just one problem - no output.  

Another weird thing.  I go to the status menu and check meters  STATUS/FX/METER 
output voltage and it says “4V”.  So it knows that it is not working but it 
appears to have no qualms or misgivings about this state of affairs.  NO error, 
no warning, two green lights.

I tried rebooting with the battery fuse.  I tried resetting to factory 
defaults.  No joy.

I suppose I will take it to pieces and try to figure out a hardware failure but 
I wonder if anyone has seen this and can give me a clue?

cheers
Hugh
