EcoFlow DELTA Pro 3 Portable Power Station (4096Wh)
The DELTA Pro 3 is the point in EcoFlow's range where a portable unit becomes genuine home backup. 4000W continuous with true dual 120V/240V output means it runs a 3-ton central air conditioner or a 1 HP well pump — the loads that force most power stations to sit them out — and an 8000W surge covers their startup.
4096Wh expands to three units in parallel for 12,000W, and 0–80% takes 50 minutes with multi-charge input up to 7000W. It's the first power station with an IP65-rated battery pack, resisting water, dust, impact and fire, wrapped in a UL-certified 5VA fireproof shell and monitored by an X-Guard BMS watching 40 safety indicators. 4000 cycles to 80% works out to roughly 11 years of daily use. No installation needed — wheel it in and plug it in.

Why the DELTA Pro 3
True 120V/240V, 4000W
Dual-voltage output runs a 3-ton central AC or a 1 HP water pump — the 240V loads that single-voltage power stations simply can't touch.
IP65 Battery Pack
The first power station with an IP65-rated pack — resistant to water, dust, impact, and fire, inside a UL-certified 5VA fireproof shell.
Scales to 12,000W
Run three DELTA Pro 3 units in parallel for 12,000W, so several high-draw appliances work at once without juggling plugs.
0–80% in 50 Minutes
X-Stream 1C charging, and multi-charge combinations take total input as high as 7000W.
11 Years of Cycles
Automotive-grade LFP cells rated 4000 cycles to 80% capacity — about 11 years of daily use before reaching rated end-of-life.
No Installation Required
Wheels, an ergonomic handle, and plug-and-play setup — no electrician and no remodelling unless you add a home panel.
Building Your Configuration
This listing offers three independent choices, which combine into twelve possible configurations. Rather than list all twelve, here's what each choice actually does — pick the ones that match your situation.
Choice
Your Options
What It Changes
Who Needs It
Expansion Batteries
None, 1, or 2
Adds stored energy — how long you can run, not how much you can run at once
Anyone expecting outages beyond a few hours. Two batteries roughly triples your runtime
Smart Home Panel 2
None or 1
Connects the system to your house — up to 12 circuits under app control, with automatic 20ms switchover
Anyone who wants the lights to come on by themselves rather than running extension cords. Needs an electrician to install
Smart Generator 4000
None or 1 (dual fuel)
Adds a fuel-powered recharge source that starts and stops itself as the battery needs it
Anyone facing multi-day outages without reliable sun. This is what turns hours of backup into indefinite backup
The one to think hardest about is the Smart Home Panel 2, because it's the only choice that involves an electrician — batteries and a generator can be added any time, but retrofitting the panel later means paying for a second visit. If you think whole-home automatic backup is where you'll end up, it's cheaper to do it in one go. Call us at (303) 876-7654 with a photo of your breaker panel and we'll tell you what's realistic.
What's Included
In the Box
EcoFlow DELTA Pro 3 power station (4096Wh)
AC charging cable
User manual and warranty card
Your selected expansion batteries, Smart Home Panel 2, and Smart Generator 4000 ship alongside with their own cables and documentation. Connecting to your home through the Smart Home Panel 2, an inlet box, or a manual transfer switch is licensed electrical work — the power station itself needs no installation at all.

Warranty
EcoFlow 5-year coverage — see the note below on how this is structured
A note on the warranty: EcoFlow's advertised 5-year cover across the DELTA range is generally a 3-year standard warranty plus a 2-year extension you claim by registering the unit in the EcoFlow app. Registration is free and takes a couple of minutes, so it's worth doing the day your unit arrives — call us at (303) 876-7654 if you'd like the exact terms for this model confirmed.
If you're adding the Smart Home Panel 2, your electrician will want its installation documentation before quoting the work.
Up to 5-Year Warranty
EcoFlow's 5-year coverage. Register the unit in the app on arrival to be sure of the full term.

EcoFlow DELTA Pro 3: Frequently Asked Questions
Can it really run central air conditioning?
Yes — EcoFlow rates it for a 3-ton central AC unit, and that's the main reason to choose a DELTA Pro 3 over a DELTA 3 Ultra. It comes down to true dual 120V/240V output at 4000W with an 8000W surge; 240V appliances like central air, a well pump, or an electric range need that voltage, not just the wattage.
Which of the three options should I add?
Think about them separately. Expansion batteries decide how long you run — add them for outages lasting more than a few hours. The Smart Home Panel 2 decides whether backup is automatic and whole-home rather than extension cords, and it's the only option needing an electrician, so it's the one worth deciding up front. The Smart Generator 4000 is what turns hours of backup into indefinite backup when there's no sun. Call us at (303) 876-7654 and we'll work through it with you.
Do I need an electrician?
Not for the power station itself — it's genuinely plug-and-play, with no installation and no changes to your house. You only need an electrician if you add the Smart Home Panel 2, an inlet box, or a manual transfer switch, since those tie into your home's wiring.
How long will 4096Wh last?
At a 1kW average draw — fridge, lights, internet, electronics — roughly four hours. Running central air will cut that to about an hour. Two expansion batteries take total capacity past 12kWh, which is where multi-day essential-load backup becomes realistic. Adding the Smart Generator 4000 removes the runtime limit entirely.
What does the IP65 battery pack actually mean for me?
It's the first power station pack rated IP65, meaning the battery itself resists dust and water jets, and EcoFlow also rates it against impact and fire inside a UL-certified 5VA fireproof shell. Practically, it makes the unit far more tolerant of a garage, a job site, or an RV than a typical power station — though the ports and screen still aren't something to leave out in the rain.
How fast can I recharge it?
0 to 80% in 50 minutes using 1C X-Stream charging, and combining charging sources takes total input as high as 7000W. That's fast enough that a short window of grid power during a rolling outage genuinely refills the system.
Can I use it as a UPS for a server?
Yes. It switches over in 10 milliseconds directly, or 20 milliseconds through the Smart Home Panel 2, which protects NAS systems, servers, and entertainment equipment from dropping out or losing data during an outage.
How is it different from a DELTA Pro Ultra?
The DELTA Pro 3 stays portable — wheels, a handle, no installation — and delivers 4000W, scaling to 12,000W with three units. The DELTA Pro Ultra is a fixed home system: 7.2kW per inverter for the original and 12kW for the Ultra X, with far greater storage ceilings, but it's installed rather than wheeled around. Choose the Pro 3 if you want one unit that does home backup and travels; choose an Ultra if it's staying put permanently.
Is it quiet enough to keep indoors?
EcoFlow's X-Quiet technology is designed so it can sit beside a bed without disturbing sleep. As with any power station, heavy loads and fast charging spin the fans up noticeably, so the quiet claim applies to normal operation rather than a 7000W charge.
Do you offer financing or price matching?
Yes. We offer 0% APR financing options through Affirm at checkout, and every purchase is backed by our Lowest Price Guarantee — if you find a better price elsewhere, call us at (303) 876-7654 before you order.
