A 4 kWh EcoFlow DELTA Pro 3 solar generator with two portable 400W panels. Quiet, fume-free, and safe to run indoors — so your essentials never go dark.
A gas generator roars on the patio all night. This one runs near-silent — keep it right inside, in the same room where the kids are sleeping. No fumes, no fuel to store, nothing to maintain.
When the power drops, you just plug in — no rewiring, no electrician, no fuss. It ships straight to your door, ready to run out of the box, with a step-by-step setup video that walks you through everything.
Holds enough power to run your essentials for days. Rolls anywhere on built-in wheels — plug in the moment you need it.
Unfold them in the yard and they refill the battery straight from the sun — free power, no gas-station runs.
It ships right to your home by carrier — no appointment needed. We send a step-by-step setup video, and you track everything from a simple phone app. (In-home setup or whole-home integration available as an add-on.)
Here's how a single outage actually plays out when the DELTA Pro 3 is sitting in the corner, charged and ready.
No scramble for cords or fuel. The unit's charged and waiting in the corner — ready the moment you need it.
Plug your fridge and WiFi into the unit — or, tied into a transfer switch, they switch over automatically — and they keep running without missing a beat.
The house feels normal — quietly. No roar from the patio, no fumes drifting in the windows.
Medical devices and cooling carry through the night on a single charge.
Set the two 400W panels in the yard and the battery tops back up — free, from the sun.
Run by night, recharge by day — for as long as the outage lasts. No countdown, no gas runs.
Hands-off, automatic switchover happens when the unit is tied into a manual transfer switch or smart home panel (optional add-on). Without one, you simply plug your essentials directly into the unit.
Run one big appliance on its own, or keep all your everyday essentials going through the night. Here's exactly what a single full charge holds.
Run-times are for each appliance running on its own; mix the smaller stuff together and it stretches much further — and the panels refill it by day.
Empty to nearly full in about the time it takes to make dinner — so it's ready and waiting before the storm even arrives. No gas runs, no waiting around.
Start with a single unit for your essentials. Stack extra 4 kWh batteries onto it, or combine up to three DELTA Pro 3 units through a smart home panel — up to 12 kW of output and 48 kWh of storage to carry an entire home for well over a week.
It's built with the same long-life battery as electric cars, and it's certified safe to live with. This isn't a gadget you replace in a year — it's something you'll lean on season after season.
Check your power right from your phone — see how much you have left, anywhere, anytime. Our setup video walks you through pairing the app in minutes, so there's nothing to figure out.
Know exactly how much power you have, in real time.
Tune charge speed and shed loads to stretch power further.
Get a heads-up before the battery runs low — never caught off guard.
