A/C and an inverter

How big of an inverter would be required to start a 15k btu a/c? I'm not interested in the 12v supply debate, just need to know how many Watts to start the unit. 2500 continuous/5000 surge?

  • A 15K AC is typically going to require about 20-25 amps to start and around 18 amps running.
    Meaning your inverter would consume about 200-250 DC amps to start out of your battery bank.
  • What model of A/C? There should be a listing of what it takes to run it. Others here do run their A/C off of their system. I do but it's just a little window shaker.
