Frequently asked questions
What size generator to run a refrigerator?
For a typical setup (refrigerator (top-freezer, ~16 cu ft)), you need at least 125W of continuous power. The single biggest moment is startup: when 1× refrigerator (top-freezer, ~16 cu ft) kicks on, the momentary draw peaks at 375W. For overnight runtime we recommend at least 1,250Wh of battery capacity (your devices use about 1,000Wh per day, plus a 25% margin).
Which power stations can handle this?
Based on published specs, Goal Zero Yeti 1500X, Anker SOLIX F1500, Bluetti AC200L all cover the 375W startup peak and give you 1.5 days / 1.5 days / 2.0 days of typical daily use. Check the comparison cards above for the full numbers.
Why is the startup surge higher than the running watts?
Motor-driven devices (fridge compressors, well pumps, air conditioners) draw 2-5× their running power for a split second at startup — measured as locked-rotor amps (LRA). A generator that only meets the running load will trip or stall when the biggest motor starts.
