I believe that a brushless DC motor delivering equal torque is may times more
efficient than an AC motor.
We always look for a DC solution for pumps etc. A second advantage when using
a Trace SW set-up is the ability to operate off the battery bank during sleep
mode, without waking up the inverter.
