Starting watts apply to motors and compressors only. Size a generator for all running watts plus the single biggest starting surge.
Put the numbers to work
Pick the appliances you need in an outage and the generator size calculator adds them up for you, including the battery size for a power station.
For battery runtime, the runtime calculator does the math.
What size generator do I need? A simple sizing method
Add running watts, then the largest starting load. Worked examples for outage essentials, a well pump and whole-house central AC, plus a size chart.
How long will a power station last? Runtime math and examples
How long a power station will run a fridge, CPAP, router or Starlink: the Wh × 0.85 ÷ watts formula, fridge duty cycle, worked examples and solar recharge.
