I am puzzled when I read of this practice too.  It sounds as if some 
people do this.  They use a charge controller to deliberately limit 
the voltage of the batteries when running on solar power (or wind) 
and then burn fossil fuels to wildly overcharge them from time to 
time.  It makes more sense to me to use a higher voltage setting on 
the controller, or no controller at all, if the batteries need more 
charging.  Equalisation should then only be needed as a last resort 
if some cells are getting low.
