How the result was calculated
Method and assumptions
- 1Running watts are added for every selected load and quantity.
- 2The largest single motor-starting jump is added to the running total. This assumes major motors are started one at a time.
- 320% safety headroom is added, then the result is rounded up to the next 250 watts.
- 4Battery capacity assumes every selected load runs continuously for 8 hours with 85% usable-system efficiency.
Before buying or connecting equipment
Check the actual nameplate wattage for every load. Central HVAC, hardwired pumps, well systems, medical equipment, transfer switches, and panel connections should be reviewed by qualified professionals. Never operate a fuel-burning generator indoors or near doors, windows, or vents.
