Welcome Cj,
I'll just add one other consideration to Spar & Adriaan's comments, just to say that 100AH is not a lot of storage. Most small wind turbines are vastly over-rated. Their "rated power" is often at a wind speed that is higher than all but a finite set of storms. Still, if each unit was hitting 500w, you might see some 35 amps (assuming a 12V system) on each, or a little over 100A combined. Your battery in those, albeit rare, conditions would only sustain that charge level for maybe a half-hour before the controllers would be starting to reduce the charge rate. A portion of the available power soon needs to go somewhere other than the battery, and you're looking at a diversion/dump load to burn some of it off as suggested.
