Spartan Power SpartanStart Soft Starter for RV Air Conditioners


SKU: SpartanStart Category:


The SpartanStart is designed to be used across a wide range of RV air conditioner units, up to 20K BTU. Unlike commonplace designs, this soft-starter only requires access to the compressor’s three wires (Run, Start, and Common). Very easy installation, only 6 wires, 3 per side! Made in Australia.


SpartanStart RV A/C Soft Starter Features:

  • Start up to a 20K BTU RV AC with a 2200 watt power inverter or generator! Not only will the SpartanStart reduce the drain on your battery bank during startup, it also greatly reduces A/C compressor noise and vibration.
  • EASY INSTALL: Just 3 wires (6 crimps). The SpartanStart goes inline with your compressor. Find the wiring diagram on your A/C that shows the R (Run), C (Common), & S (Start) wires coming off the compressor. Match & connect those wires to the appropriate wires listed on the SpartanStart. Done! For full installation instructions, please consult the manual or give us a call.
