task. I'd think a contactor on the HV PV output side suitably rated for 
voltage/current triggered by the aux output once the Classic goes into float 
would do the trick. I recall the Classic has that feature but never used it yet.

  <DIV>The thought was to charge the batteries for a new building utilizing an 
  SW4024 with new classic controller and new L A batteries, and once those 
  batteries are charged send the PV to the house system which is the 48v setup 
  with dual outback inverters and dual SB3048 CCs. &nbsp;Lead acid batteries as
