MidNite's Classic series of MPPT Charge Controllers features HyperVOC, a non-operative VOC safety zone over and above the maximum input voltage.
Read about it here.

good explanation...
made me go look up the manual for my old Blue Sky 2000e. :o
They used 30V max for 12 V system, phew. :) no smoke...

I agree with Eric. Great explanation of the HyperVOC feature.

We used to spend an enormous amount of time at OutBack explaining why you can't put X amount of panels in series. Now we spend an enormous amount of time explaining why you can!
The write up does help though.
Does Hyper VOC apply to the Classic when used for Wind/Hydro? In other words does the Classic allow the ability to exceed the maximum (150, 200 or 250v depending on model of Classic)for brief periods of time or will the results exceeding the max Classic voltage just be clipped with a Clipper?

Yes, Hypervoc applies to Solar, Wind or Hydro.

The OP seems to be empty ?

Mike;
I poked Ryan on this.
Basically. HyperVOC allows the Classic to operate at a higher voltage than the rating in deep cold weather. Like rating plus battery volts.
Ryan will explain better.

The Classic will not operate while in hyperVoc. On the other hand it will not be harmed by the hyperVoc overvoltage.
HyperVoc will occur early in the morning when there is not much power to harvest anyway. When the sun hit the panels they will warm up and the voltage will drop back into operating range.

Yes, good catch. Poor word selection there. Should have said "tolerate".
