Classic cycling between resting, pv shade and bulk mppt

If it can be fixed and warrantied i will buy it back.

The reason I asked is, IF it is what I THINK it might be, it could be fixed without removing circuit boards.

Just a resistor on the top PCB.   If you had a multimeter, you can check the resistor to see if it is open.

Not sure if you can solder or not.

I can check it, is there a circuit diagram so I know what to look for?

Found a VERY dusty Classic around.

The resistor that is circled should be 10 or 20 Ohms.

Guessing that it might be open.  It might measure some high value though but would still be bad.


IF this is the problem and if you fix it, you will have to talk with someone at MidNite Solar about it.
I can mention what has happened here though  *IF* that is even the problem 

Good chance that it is though based on what I have seen.

Ok- i have a support ticket so I can pass findings here and up the chain via my ticket.

[schroew]

It measured 2.9M ohms… i will relay this to support.

[boB]

Yep !   That's the problem then

I do NOT know what the policy is or what we do when you are sent a return ticket and another unit and are able to fix the original unit with a bad resistor like this...

I'm not THAT wise in these matters  😁

I have worked this out with support, all is well. Thank you so much for your help!

Fantastic !!

I am glad when a plan comes together !
