Description
3600W Output: Powerful, Stable, Built to Handle It All
The EcoFlow DELTA 3 Ultra Plus (3072Wh), one of our EcoFlow Generators, delivers 3600W of rated AC output with a 7200W surge. With X-Boost 3.0 technology it supports devices up to 4600W, effortlessly handling heavy-duty appliances like clothing steamers, electric dryers, lawnmowers, and electric frying pans. A high-precision DSP chip samples AC voltage and current every 33 microseconds, delivering pure sine wave output with beyond grid-level stability for powering sensitive electronics reliably.
Why You Need the EcoFlow DELTA 3 Ultra Plus
Whether it's a multi-day outage, a full RV setup, or a busy job site, the DELTA 3 Ultra Plus is built to keep everything running. Automotive-grade full-tab LFP cells and an EV-grade cell-to-chassis structure protect it from overnight condensation and off-road bumps during transport, while a 24/7 battery management system tracks temperature and charge in real time. Two DC ports, an Anderson port and a car cigarette port, keep 12V gear running, and a TT-30 outlet supports your entire RV setup. With Smart Output Priority, you decide which circuits, like your fridge or medical devices, stay powered longest when it matters most.
EcoFlow DELTA 3 Ultra Plus Features and Benefits
3600W Powerful Output, 7200W Surge
With X-Boost engaged, the DELTA 3 Ultra Plus supports heavy-duty appliances up to 4600W, including clothing steamers, electric dryers, lawnmowers, and electric frying pans, so your kitchen, laundry room, and garage stay powered without a hitch.
4 Ways to Charge, Ready in Just 60 Minutes
Charge from a wall outlet, solar panels, an alternator charger, or combine solar and alternator input at once for the fastest of the four, reaching 0 to 80% in about 60 minutes. Storm Guard Mode can automatically trigger AC charging remotely ahead of severe weather once activated in the EcoFlow app.
Smart Output Priority, Extend What Matters Most
Manage each outlet remotely from your phone. Prioritize essentials like your fridge or medical devices to extend runtime when it counts most, even when you're away from home.
10ms Auto-Switch, Zero Interruptions
During a power outage, the DELTA 3 Ultra Plus switches from grid to battery power automatically within 10 milliseconds, no manual intervention required, keeping NAS systems, servers, and other critical devices running smoothly.
Long-Lasting, Durable, and Reliable
Automotive-grade full-tab LFP cells are estimated to deliver around 10 years of reliable use, backed by 24/7 battery protection and a cell-to-chassis structure that's drop-resistant to 0.2m, guarding against overnight condensation and off-road bumps during transport. It's built to keep running through freezing cold, scorching heat, up to 95% humidity, and coastal air with 5% salt spray resistance, and it's certified to Class B EMC standards so it won't interfere with your TVs, Wi-Fi, or other home electronics.
25dB Whisper-Quiet Operation
Powered by X-Quiet 3.0, EcoFlow's stepless fan control adjusts airflow smoothly to maintain precise thermal regulation, holding noise to 25dB or lower under a 600W load, keeping your home or workspace peacefully quiet even under heavy loads.
Power That Grows With You
Start with the 3072Wh built-in battery and scale up to 11kWh with compatible extra batteries as your needs grow. Pair it with an EcoFlow Smart Generator for automatic fuel-to-battery switching and extended runtime through multi-day outages or off-grid adventures.
Smart App Control With EcoFlow's Energy Dashboard
Monitor energy usage and solar generation from one intuitive dashboard. Set timed charging and discharging missions so you can charge during off-peak hours and discharge during peak rate periods to save on your electricity bill automatically.
Storm Guard Mode: Ready Before the Storm Hits
Storm Guard Mode monitors severe weather alerts and automatically triggers AC charging remotely using X-Stream fast charging technology, so the DELTA 3 Ultra Plus is topped off long before a disaster hits. Activate the preset once in the EcoFlow app and it runs on its own from then on.
Solar Charging: Camp Off the Grid
At 1600W input, the DELTA 3 Ultra Plus goes from 0 to 80% in about 101 minutes when paired with EcoFlow's 25% high-efficiency 400W Solar Panels (sold separately), ideal for camping trips, van life, or extended off-grid living where a wall outlet isn't an option.
How Long Can It Power Your Home?
Runtime scales with how much battery capacity you add, based on ideal conditions and typical appliance loads. Actual results will vary.
Half-Day Outage
The 3072Wh base unit covers essential power needs, keeping food fresh, cooling running, work uninterrupted, lights on, and devices charged through a 4 to 10 hour outage.
1-Day Outage
With the 3072Wh base capacity, expect uninterrupted cooking, heating, lighting, and connectivity for a full day.
2-Day Outage
Expanded with an extra battery, it keeps your kitchen running, home office working, lights on, and devices connected for 2 days.
3-Day Outage
Expanded further with additional batteries, it supports a family through 3 days of everyday living, keeping food fresh and devices charged.
Charging Options
The DELTA 3 Ultra Plus offers four primary ways to recharge, so it's ready whether you're indoors, outdoors, or on the road:
- Wall Charging (1800W Max): 0 to 80% in about 89 minutes using X-Stream fast charging technology.
- Solar Charging (1600W Max): 0 to 80% in about 101 minutes when paired with EcoFlow's 400W Solar Panels (sold separately).
- Alternator Charging (1000W Max): 0 to 80% in about 142 minutes using the EcoFlow Alternator Charger Plus 1000 (sold separately), about 10x faster than conventional car charging.
- Solar + Alternator Dual Charging (2600W combined): Combines 1600W solar and 1000W alternator input for a 0 to 80% charge in about 60 minutes, the fastest of the four.
You can also pair the DELTA 3 Ultra Plus with an EcoFlow Smart Generator 4000 (Dual Fuel, sold separately) for generator charging at up to 3200W, reaching 0 to 80% in about 53 minutes, with automatic start and stop for hands-free backup during extended outages.
Charging speed figures are measured in optimal lab conditions and may vary depending on usage environment, device condition, and software version.

Federal Solar Tax Credit
A Brief Overview of the U.S. Home Energy Tax Credit
Discover the financial advantages of the U.S. federal solar tax credit for homeowners considering installing a solar system in their main residence. This incentive provides a 30% discount on the current cost of a solar system. If you've set up a system in 2022, it's advisable to speak with your tax consultant to see if you're eligible for a higher credit rate.
Understanding the U.S. Federal Solar Tax Credit:
This tax credit is tailored for homeowners and applies to solar systems installed in primary homes. The credit covers a percentage of qualifying expenses, and thanks to the recent Inflation Reduction Act, the scope of the Investment Tax Credit (ITC) has broadened. Solar systems installed from 2022 to 2032 are eligible for a 30% tax credit, which will drop to 26% in 2033 and 22% in 2034. There's no cap on the amount you can claim.
What Expenses Are Eligible:
Qualifying expenses include solar photovoltaic panels, attic fan power systems (except for the fan itself), labor costs for installation and setup, balance-of-system components, and applicable sales taxes. Standalone batteries with a capacity of 3 kWh or more may also be eligible! For instance, if the solar system you initially purchase includes a single battery with a capacity of less than 3 kWh, but you also buy extra batteries during the installation process that bring the total capacity to more than 3 kWh, then the entire setup may be eligible for the tax credit.
How to Determine Your Eligibility:
To confirm your eligibility for this federal solar credit, review the guidelines set forth by the U.S. Department of Energy and consult your tax advisor.
Steps to Claim the U.S. Federal Solar Tax Credit:
Verify Eligibility: Speak with your tax advisor to confirm your eligibility and to understand how to make the most of the credit.
Fill Out IRS Form 5695: This form, available online, is specifically for claiming renewable energy credits. Guidelines for completing the form are provided.
Apply Credits on Your 1040: Use the total credit amount from Form 5695 to lessen your tax liability on your Form 1040.
