DC Split 18000 BTU

Direct Current Air‐Conditioner

  • Daytime and Night Time Operation
  • 18,000 BTU Nominal Capacity
  • Optimized for Solar Air Conditioning
  • Variable Speed BLDC Compressor
  • Uses Standard DeepCycle Golf Cart Batteries
  • All DC – No Inverter
  • Works with Standard PV Panels
  • Cooling and Heating Modes


100% DC ‐ No Inverter = No Energy Wasted

The DC18 solar air conditioner has been designed to make the best possible use of costly solar photovoltaic panels. The DC18 can use approximately 40% fewer solar panels than would be required by a standard AC‐powered  air conditioner of the same max capacity running off solar panels through an inverter. The system is perfect for residential, commercial, telecom, portable classrooms or offices, or remote facilities where conventional or generator power is costly and/or unreliable.
