Our take on the EcoFlow Delta Pro Portable Power Station & 400W Solar Panel

The EcoFlow Delta Pro is a large home-backup power station paired with a 400W folding solar panel. It uses LiFePO4 batteries rated for around 6,500 cycles to 80% capacity and delivers 3,600W continuous output with a 7,200W surge, enough to run a window AC, a fridge or a sump pump. The 400W panel folds for transport and recharges the unit from the sun. It suits homeowners building outage backup or off-grid setups; rivals like the Bluetti AC300 split the battery from the inverter, while the Delta Pro keeps everything in one heavy, wheeled case. Owners praise the output and recharge speed but note the weight and app quirks.

Questions and answers

Can the Delta Pro run a whole house?
It can carry essential circuits like a fridge, lights and a sump pump, and with extra batteries or a transfer switch it covers more. It is not a full substitute for a home generator for central AC and everything at once.
How long does the 400W panel take to recharge it?
Expect several hours of good sun to make a meaningful dent, and longer for a full charge. Adding more panels raises the solar input and shortens recharge time.
Is it loud?
The fans are audible under heavy load and quiet at low draw. Most owners find the noise acceptable for garage or outdoor use.
Can I expand the capacity later?
Yes. EcoFlow sells add-on batteries that stack with the Delta Pro to increase stored energy.
What comes in the box?
The Delta Pro unit, the 400W folding solar panel, charging cables and the solar connection cable. Check the listing for the exact bundle contents.
Can it be charged from a regular wall outlet?
Yes, it charges from a standard AC outlet and supports fast charging. It also accepts solar and car charging.
