What voltage before excess power is sent to the dump load?

I was in our battery shed the other day while the wind turbine was spinning really fast. The LCD screen said the battery bank as was 12.8, but I could feel the heat being dumped into the resisters. Should it really be dumping at such a voltage? I was under the impression it wouldn't start dumping until the bank reached 14.0 volts or higher.

Thanks!
 
Is the dump load on the battery or on the turbine. It could be clipping on peaks. A lot depends on the design, but that certainly sounds wrong.
 
The dump load is setup to come right off the power being generated on the turbine. Okay, I'll dig into the user manual and see what's going on. Thanks.
