I was looking to buy a classic 200 from a retailer in Australia so I placed an order only to receive an email saying they were out of stock of that model but I could have the Classic 250 for the same price and they had it in stock.
Ok I did some calcs and I decided I could use it and subsequently replied to them that I would accept their offer.
I arrived today and of course I opened it up to only see that the transformers and ethernet connection were labeled "Lite 250".
It has the MNGP which was connected.
Also I see the back section has a groove for a seal but there is no seal.
What model did I get?
Thanks
Peter
Got a picture of it.
Hi Peter.
A Classic "Lite" is exactly the same as a non-Lite EXCEPT for two things...
The Lite does not ship with an MNGP remote control panel. They gave you
one of those so that part is taken care of.
The other difference is that the Arc-Fault circuit board is not installed on the bottom
of the power board. Australia does not have a AF requirement. It is also unnecessary
for normal operation.
Other than this, everything else including software/firmware and capabilities
are the same.

Thanks Bob,
So what does the arc fault do?

Hi Peter, believe that the groove that you refer to is in the casting, and looks to me like it might have been designed to accept an "O-Ring" type of seal. Have NEVER seen a Classic that has such a seal. So if that is what you was mentioning, believe that you are not missing anything in this case. FWIW, Vic

An O-ring there would not do much considering The Classic has vent holes in the body and the cover.
Just a couple thoughts.

Yea, Tom,
Had deleted a line in my post that noted the Classic has a well-ventilated case, but felt that this was a bit redundant ...
But, do believe that this was what the groove was for, or perhaps an emission gasket (which seems likely). Tooling is expensive, and had felt that this groove was there just in case it might be needed for some special application. All FWIW, Vic
you should do a search for Arc Fault here. It is a complex issue and best if you read what boB and others have to say, rather than muddy the waters...

AF looks at the noise coming from the PV current and if it thinks that there is electrical arcing happening,
it will shut the controller off until you hit a button on the screen.

Thanks to all who replied,
It appears then that the Arc Fault Detection is basically a safety device.
It would protect the system if for example an isolation switch failed, of which I can see that in Australia at least there have been recalls of these because of this exact reason and the net is littered with images of same.
As the Australian regulations mirror that of the U.S. I can safely guess that it will not be long before a similar requirement is introduced here.
After researching various controllers my decision to buy the Midnite Classic was influenced by it's features, the general opinion of it from this forum and others, and the VALUE for money.
Then as the manufacturer promotes this as a feature of the controller, it can be only be that without it, the controller is of lesser value irregardless of its importance or requirement.
On the box it appears that the the contents are described by a barcode sticker placed over the corresponding tick box indicating a Classic 250.
So, did the manufacturer get it wrong?
The box had been previously opened and taped up again, evidenced by the supplier enclosing their 'welcome letter' and invoice in the box.
The MNGP was connected to the controller, as per the included literature this is not done at the factory.(" The graphics display panel (MNGP) may be attached to the main circuit board with a blue phone style cable as seen below if this is not the first time being opened")
So, who would have done this, the manufacturer?
As previously descibed upon noticing the 'Lite 250' stickers I began to question the validity of the controller. Another thing I have since noted is that the alignment markings on the screws and washers holding the mosfet retaining bar in place do not appear to be in alignment.
So again, who would have done this, the manufacturer?
If the mosfet retaining bar had been 'Moved', why. This now leads me to believe this is a used unit that has been repaired.( if in fact it works at all )
If there was a fault with the unit and I returned it to the manufacturer/agent for repair under warranty what would they make of this and would they honour the warranty?
My original post was to determine whether what I got, was what I paid for.
If you were to go to the pub/liquor store and pay for a six pack and only get 5 and 1 of them had been opened what would your response be?
And yes, I have opened a line of communication with midnite solar and the supplier.

If you want to give me the serial # in a PM if you dont want it public. I will look it up and tell you what it left Midnite as. But with the stickers I am pretty sure I already know. Anyhow drop me the serial # and I will look it up

Thanks Ryan,
PM sent.
One thing I have to say is that from what I can see the build quality is impressive.
From the diecast aluminium case to the components and assembly I would be very happy if it were the right one :P.
