How long will it run a refrigerator?

A typical fridge draws a few hundred watts with compressor surges. At 3072Wh the DELTA 3 Ultra Plus can keep one running for well over a day, and adding batteries stretches that further.

Can it power a whole house?

It can back up selected circuits through a manual transfer switch or inlet box, not an entire panel at once. The 3600W output and 10ms switch suit critical loads like fridges, networking gear and lights.

What's the difference from the DELTA Pro?

The DELTA 3 Ultra Plus uses LFP cells rated for about 10 years and offers app-based circuit priority plus generator auto-start. The DELTA Pro line uses different cells and expansion batteries, so check compatibility before mixing.

How fast does it recharge?

EcoFlow rates it at 0-80% in about 48 minutes using solar and generator charging together. Wall charging alone is slower.

Does it work with the Smart Generator?

Yes. An EcoFlow Smart Generator can start and stop automatically to recharge the station during long outages, which is how it reaches the 11kWh end of its range.

What comes in the box?

The station itself plus charging and connection accessories. Extra batteries, the Smart Generator and home hookup hardware are sold separately.

Our take on the EcoFlow DELTA 3 Ultra Plus Portable Power Station (3072Wh)

The EcoFlow DELTA 3 Ultra Plus is a 3072Wh portable power station with 3600W continuous output and 7200W surge, built around automotive-grade LFP cells rated for about 10 years of use. It scales from 3kWh to 11kWh with extra batteries and can auto-start an EcoFlow Smart Generator for longer outages. X-Boost pushes it to run heavy appliances up to 4600W, and a 10ms auto-switch keeps critical gear like NAS systems and servers running. It suits homeowners who want whole-circuit backup or off-grid power without a fixed install; rivals in this class offer similar output but fewer ways to tie into a home's wiring and generator.
