Common questions about this product
Yes. At 2,048Wh, EcoFlow rates DELTA 2 Max to keep a fridge running for up to 14 hours.
Combining 1,000W of solar with AC gets you to 80% in 43 minutes. On AC alone, 80% takes about 1.1 hours.
It's built for partial backup — connect it with a transfer switch and up to two Smart Extra Batteries (6kWh total) to keep key circuits running, not the whole house.
It's tested with EcoFlow's own 400W Portable Solar Panel (up to two) and 220W Bifacial Solar Panel (up to four sets) to hit the full 1,000W solar input. Other panels may work but aren't covered by EcoFlow's published figures.
No. At 2,048Wh it's far over the 100Wh limit airlines set for carry-on lithium batteries.
As quiet as 30dB.
