Can Go Power Pure Sine Wave Inverter 3,000W Power 13.5k BTU AC Unit With 4 100ah Lithium Batteries?
Published 09/16/2025
Question:
Can the GP44XR run a 13.5k BTU A/C unit 120v if I’ve got four 100Ah lithium batteries?
asked by: Michael
Expert Reply:
Michael, technically the inverter # GP44XR has the wattage of 3,000 continuous, but A/C units are the hardest load for batteries. A 13.5k BTU pulls about 1,500 watts when running, but surges much higher at startup unless it has a soft start installed. Your four 100Ah lithiums might get it going, but expect very short runtime before depletion. Most folks still use a generator for A/C and let the inverter handle everything else. But if you had 4 of the 200ah instead of 100ah, you'd get a few more hours of run time on the AC for sure. Solar also helps if you need that too.
Do you want it mainly for short cool-downs, or full-night operation?
