4096Wh DELTA Pro 3,4000-Watt Output

EcoFlow DELTA Pro 3 is a whole-home backup power station — 4096Wh of LFP battery capacity with 4000W AC output handles an entire home's essential load simultaneously, and the expandable architecture allows adding additional battery units to extend storage capacity to 12kWh or beyond. At 4000W continuous output with 8000W surge, the DELTA Pro 3 manages central air conditioning, refrigerators, and high-draw appliances that smaller power stations can't handle.

Who Needs 4kWh+ of Portable Power

Households in storm-prone regions where multi-day grid outages are realistic. RV owners who want shore-power independence at dispersed campsites without a generator. Homesteaders building solar-plus-storage off-grid systems where a standalone battery storage unit is needed. Remote hunting and fishing camps where a seasonal power supply needs to run lights, a freezer, and charging stations continuously for extended periods. At 4096Wh, the DELTA Pro 3 can power a full-size refrigerator for approximately 3 days without solar recharge.

Home Backup Sizing Calculation

Calculate your essential load by summing the running wattage of the devices you need during an outage: refrigerator (100-150W), lights (50-100W), internet router (15-25W), device charging (50-100W), and any medical equipment. At 300-500W of sustained essential load, 4096Wh provides 8-13 hours of continuous operation without solar recharge. With solar panels charging during daylight hours, the system maintains indefinite operation in areas with reliable daily sun.
