Frequently asked questions
What size generator do I need for run pool pump?
For a typical setup (Pool Pump (variable-speed, high) and Router + Modem), you need at least 815W of continuous power. The single biggest moment is startup: when 1× pool pump (variable-speed, high) kicks on, the momentary draw peaks at 2,415W. For a full day of runtime we recommend at least 6,450Wh of battery capacity (your devices use about 5,160Wh per day, plus a 25% margin for a full day of use).
Which power stations can handle this?
Based on published specs, Bluetti AC200L (with expansion batteries), EcoFlow DELTA 3 Max Plus (with expansion batteries), EcoFlow DELTA Pro 3 (with expansion batteries) cover the 2,415W startup peak and deliver up to 1.6 days fully expanded / up to 1.9 days fully expanded / up to 2.4 days fully expanded 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). On this page the biggest spike comes from the Pool Pump (variable-speed, high): a station that only meets the running load will trip or stall when it starts.
