How the record reads

Energy, output, and the appliance are three separate gates

The battery decides duration. The inverter decides whether a load can run and start. The appliance decides the voltage, connection, and surge demand that must be met.

EcoFlow DELTA Pro 3 power path from 4,096 watt-hours of battery capacity through 4,000 watts of continuous AC output to the connected appliance.

Refrigerator planning profile

An estimated 63.0 hours from the visible defaults

This calculation uses a 150W running load, 1,200W starting load, 33% duty cycle, 90% usable capacity, and 88% AC efficiency. It is planning math, not a measured refrigerator test.
