EcoFlow just announced its latest “most powerful” and “easy-to-install” whole-home battery backup system. It’s called the Delta Pro Ultra X because when you’ve already launched the superlative-laced Delta Pro Ultra in 2024, the only thing left is to add a variable to the name.

Perhaps that X stands for 60 percent, which is the increase in power output over its predecessor. The Delta Pro Ultra X is capable of 12kW of continuous output, now scaling up to 36kW when three inverters are used in parallel. That’s enough to power a large central A/C system, induction oven, or EV charger.

Battery capacity scales from 12kWh up to a massive 180kWh. For context, the average US home consumes about 29.2kWh per day, according to the US Energy Information Administration. So, maxing out a Delta Pro Ultra X could power an entire home for about six days, or weeks if you’re only powering critical devices after having EcoFlow’s electrical panel professionally installed.

The Delta Pro Ultra X works with EcoFlow’s third-generation Smart Home Panel. The 200 amp panel can be installed as a main panel or subpanel to monitor and control up to 32 circuits. That way you can easily shut off non-essential loads during a blackout. It supports Time-of-Use to automatically charge and discharge the battery based on real-time pricing and forecasts in the region, and works with third-party gas generators, solar panels, and EV chargers.

And like its predecessor, the Delta Pro Ultra X is modular. That means you can scale the installation over time, easily transport it to a new home, or even take an inverter and battery with you to power a holiday home or RV for the summer.

EcoFlow is also leaning into the ease of installation in the US, touting its 425 certified installer partners, across almost every state. “The Delta Pro Ultra X system can be installed in under seven days from scheduling, with just one day needed for the on-site setup by EcoFlow-certified electricians,” says the company in a press release.

A Delta Pro Ultra X bundle — featuring the inverter unit and two expansion batteries — costs $7,999. The bundle increases to $10,899 if you also want the Smart Home Panel 3, which can be purchased separately for $2,999.
