Product Details
The Ecoflow Delta Pro Ultra Expansion Battery is the modular add on item to the Ultra Power Station, a whole-home backup solution that offers unwavering power for extended outages and daily use. With an unrivaled capacity of 6kWh, you can expand enough to run your entire home. When paired with EcoFlow Smart Home Panel 2 (and Delta Pro Ultra Inverter), get an uninterrupted power backup experience with automatic switch-over, energy consumption monitoring, and lower electricity bills through advanced EcoFlow app settings. With its plug-and-play stackable design, you can expand the EcoFlow DELTA Pro Ultra storage and output in minutes. Compatible with a wide range of energy sources, from solar to gas, to meet your ever-changing power needs.

Expansion Batteries:
Designed to be paired with the Ecoflow Delta Pro Ultra Powerstation
When paired with the Delta Pro Ultra Inverter, it creates the perfect option for Refrigeration, Lighting, TVs, Computers, Smart Devices, Fans, Washers, and so much more!
The Delta Pro Ultra is scalable from one battery of 6kWh, all the way to 15, it multiplies the energy to a gigantic 90kWh.
Requires no gas and emits no pollution.
6kWh - 90kWh Capacity:
The Delta Pro Ultra + Expansion battery is scalable from one battery of 6kWh, all the way to 15, it multiplies the energy to a gigantic 90kWh. For a standard household during a blackout, that's over 30 days of essential power to keep appliances like lights and refrigerators running strong (time may vary depending on use).
Start small and portable and work your way up to an entire home system!


120V & 240V Output:
When paired with the inverter, it features an exceptional 7200W output, peaking at 10.8kW for 10 seconds, allowing you to run almost any household appliance, even a 3-ton central air conditioner.
Pair with the All New EcoFlow Smart Home Panel 2 and triple the inverters for an incredible 21.6kW AC output, allowing you to live life to the fullest even during an outage.


5.6kW - 16.8kW Solar Input:
Using a combination of high and low voltage input (required to output or input power), a single inverter achieves an incredible 5.6kW input max. With the help of 3 inverters and (42) 400W solar panels, triple the input to an epic 16.8kW so you can generate an entire day's worth of energy in just 1 hour!
EcoFlow DELTA Pro Ultra and Battery combination allows you to customize your power using a flexible or rooftop solar system and make energy independence a reality.


ATS, Extended Backup, and Bill Savings in One:
With the EcoFlow Smart Home Panel 2's rapid automatic switchover, you'll never even notice the grid was down. Use the EcoFlow app to prioritize specific circuits in your home, extending your backup even longer.
For more than just blackouts, it intelligently analyzes your home power usage to offset peak rates while utilizing solar to lower energy bills.


3 Ways To Connect with your Home:
The EcoFlow Smart Home Panel 2 will give you automatic transfer capabilities and a Smart View of how you use your power. Features compatibly with 1-3 Delta Pro Ultra Units, up to 5.6-21.6kW Solar input power and 6-90kWh storage potential.
