The terms “DELTA” and “RIVER” as mentioned on this page refer to products exclusively manufactured by ECOFLOW INC.
Introducing the world's first portable home battery with an expandable ecosystem for home backup, outdoor recreations, professional production, smart energy management, lower energy bills, and more. The EcoFlow DELTA Pro is the next leap in portable power technology, offering you power security and independence, wherever you are.
Power for any situation.
From tailgate power to extreme blackouts that last for days on end, DELTA Pro delivers up to 25kWh of capacity. With that, you're covered for any situation. That's the industry gold standard.
All the AC output you’ll need.
A single DELTA Pro unit packs a 3600W AC output, which can be expanded up to 4500W with X-Boost technology. Power 99.99% heavy-duty devices at home, outdoors, or at work. You can even pair two units together to achieve 7200W.
The world’s fastest charging portable power station.
MultiCharge delivers record-breaking speeds at 6500W. To reach 6500W, you can opt for these charging methods.
A battery that lasts for years on end.
DELTA Pro sports a brand-new LFP battery with 6500 cycles, which means you can use DELTA Pro for years and years before your unit reaches 50% of the original capacity. EcoFlow’s battery management system provides real-time analysis and regulation of voltage, current, and temperature. This unique protection mechanism makes DELTA Pro an incredibly safe and efficient home battery.
Works in Sync with EcoFlow PowerStream Balcony Solar System
Transform your power station into a grid-tied solar energy solution that combines solar panels, a power station, and a microinverter. Power your home and save on energy bills day and night.
Smart home battery ecosystem.
DELTA Pro's expandable ecosystem provides you with uninterrupted power during blackouts, customizable smart energy around the clock for critical loads, and lower energy bills.
Prepare your home for power outages.
When a blackout hits, the Smart Home Panel immediately switches to your 10 integrated circuits and draws power from your DELTA Pro(s). You'll barely notice a loss of power as your chosen circuits stay powered with a mere 20ms switchover time.
Expand capacity and output.
The Smart Home Panel supports and fast charges up to two DELTA Pro(s) at a time, alongside their extra batteries + smart generator(s). That gives you a potential 7200W output and 25kWh of capacity at your control, enough to power pretty much anything in your home, delivering days of power during blackouts.
Smart energy management.
Control each of your integrated home circuits via the EcoFlow app and get a birds-eye view of your energy consumption habits. Dive into the settings to customize your power use. You can optimize for home backup, saving money, or custom options to schedule your energy use based on your needs. Once you're set, you can even control which power source your house uses, all from your phone.
Save money on your electricity bills.
Draw power from your DELTA Pro(s) to power your home during peak energy use hours, this lowers your bills and reduces pressure on the grid during peak hours. During off-peak hours, use low-cost/renewable energy to charge your DELTA Pro(s) back to full.
Achieve power self-sufficiency.
Reduce your reliance on the grid and prepare for blackouts. Opt for EcoFlow's range of portable solar panels to store energy at any time, or charge from your AC coupled rooftop solar panels while the grid is on-line. No sun? We're working on a wind turbine. No sun or wind? Charge via the grid. No sun, no wind, and a blackout hits? You're still good. Lean on the EcoFlow Smart Generator as a last resort to charge your batteries.
Travel without limits.
Experience the ultimate freedom of off-grid living with a clean, silent power source, no campground necessary. With its wheels, extendable handle, and dedicated 30A Anderson port, take power along for the ride, whether you're RV-ing, camping, or just want reliable power on the go. You can even juice up your EV on the road. Now that's freedom.
Go off-grid for extended adventures.
Connect DELTA Pro with an Extra Battery for a huge capacity of 7.2kWh, and stay powered for up to a week*. Run daily essentials such as a fridge, laptop, coffee maker, and even the air conditioner. You'll have the power to experience all that nature has to offer.
*Power Van / Class B / Class C RV with daily consumption of 4kWh using DELTA Pro + Extra Battery (7.2kWh)

FAQ
When charging DELTA Pro and its extra battery together, you can reach 6500W max charging speeds by combining AC, solar and Smart Generator methods. For DELTA Pro single unit, you can recharge it at standard wall outlets (2900W max), at EV station (3400W max)/Smart Home Panel (3000W max).
It depends on the combined voltage and current of the solar panels you choose. It's fine as long as the solar panels use solar connectors and their combined voltage and current are within 11-150 volts and under 15 amps.
First of all, make sure your DELTA Pro is connected to the EcoFlow App using Internet mode. Secondly, go to the Firmware section in the Setting of the DELTA Pro you're looking to upgrade. Check for the latest firmware and follow the steps to finish the upgrade.
