Let's look into the C60's first:  I always thought that the C60's didn't have a 48V jumper setting - (see everybody learns stuff).  The Xantrex datasheets I saved a few years ago may be out of date.  I have a C40.  The label on it also says that the C60 is only for 12/24V.

I like the two identical charge controllers in parallel like that - one for wind and one for solar.  The solar one doesn't have to dump to the resistors, it can disconnect the panels any time the batteries are full.  The one for wind is connected to a dump load that looks like it will shed 50 Amps.  This is less than the C60's capability, but I don't know what windmill output you're managing.  If it's 10 feet I guess it would have to be really windy to see 50 Amps, so maybe that's not a concern anyway.

Since you have AGM's, I think that a voltage of 30V is a bit high.  The AGM's must not be so highly charged that they gas out.  There is some variation between battery manufacturers, but not much.  I float mine at 27.5 and bulk at 28V.  Any higher on my set of GNB batteries, and the manual says I would reduce the service life.

I don't see a temperature probe plugged into the CC's.  Judging by the excessively green leaves on your trees in October, I guess you live in one of those places where flakes of white fluff falling from the sky is rare.  You may not need temp correction, but with AGM's, and what I said about not gassing them, I like to have a temperature correction so that they don't sit under-charged on cold days.

The stickiest issue is whether you should set the charge controllers to different bulk or float settings, or should they be as close as possible.  That is one thing I have not yet found in Xantrex installation guides, but I'd like to know more about, too.  If they aren't set right, you could find one dumping power from the wind because it's sunny, not because the batteries are fully charged.  Without knowing more about it, I would have the two set exactly the same, because it's the battery voltage they are regulating, regardless of the source.

I would take that question straight to Xantrex tech support - no need to listen to mixed up opinions on an internet forum for that one.

Lastly, with two sources available, you can have "too much".  Windy and sunny at the same time, could you be putting 50, 60 amps into the batteries?  Can they handle that much charging current?  What is the maximum system charge current in proportion to the C/20 capacity?  Oops scratch that - I just re-read your info and you have a forklift battery.

Also I'd like to see attention toward lightning protection; you are getting into the area of major losses from getting stroked by Natures' fury (ain't talking women)... its always amazing how much grief just the static leaders of strikes that choose to happen elsewhere can inflict.

I set my wind diversion voltage slightly higher than the solar so it doesn't start dumping solar before the batteries are charged.  

The only thing you have to remember is when you manually set the solar controller to equalize you also need to set the wind controller to equalize.   One will finish before the other so you will also need to manually stop the equalize mode on the wind side.  

Using the inverter to charge your batteries when there is no wind or sun you'll need to set the wind controller to equalize mode.   Mine seems to start dumping before the internal charger is done which is a big waste of grid or fuel.   Once the charging is completed you can manually take it off equalize and it will operate normally.  

If you call Tech support about the two working together, share your conversation with us.   I'd like to hear what they said.   It has a few quirks but once you get used them it all seems to work together fairly well...

I noticed that nobody answered your question on wiring
up your dump load.

So let's back up and clarify a few things first. Don't want
to be making assumptions.

Your system is now 24 volt??

Your wind generator is 10 foot diameter swept area??

The number of coils (and number of wraps)???

You said it was a Hugh Piggott, so there are 12 magnets
that measure 2" x 1" x .5"??

If there is any other information that you can think
of, include it.
