EcoFlow Delta Pro Ultra is a smart hybrid whole-house battery generator

A residential power backup system, the EcoFlow Delta Pro Ultra is intended to handle both extended outages and daily use. Its chief role is to keep the electronics at home in operation during a power cut, but it can go further than that.

With a single-unit capacity of 6kWh, with a potential to output at up to 7,200W, it can easily keep the lights on until power is restored. Thanks to its stackable design, you can combine multiple units together, so you can considerably extend how long you can last with the power out.

At up to 90kWhn when combined with other units, that could mean up to a month of standby power is available at a moment's notice.

While it is useful in an emergency, the Ecoflow Delta Pro Ultra is also able to recharge from solar panels, including both permanent rooftop systems and flexible solar panels. Taking charge from 5.6kW to 16.8kW, it can consistently recharge from the sun, saving home owners money on their energy bills.

EcoFlow designed the Delta Pro Ultra with a new cooling structure that uses sintered heat pipes. Deemed to have a lifespan in excess of ten years for daily use, it can last for 3,500 discharge cycles before reaching 80% of the unit's original capacity.

At the same time, EcoFlow is introducing Smart Home Panel 2, which manages power sources and supply, including a 20ms auto switchover in the case of power outages. The panel includes circuit-level controls for longer backup periods, and via the EcoFlow app, web browser, and Powerinsight, users can see their usage habits and work out how to conserve even more energy.

EcoFlow will start selling the Delta Pro Ultra from January 9 via its website and on Amazon. The Delta Pro Ultra inverter and battery is $4,999, with the Smart Home Panel 2 priced at $1,599, though all can be bundled together for $6,399 until February 9.

After February 9, the launch pricing will end, with the Delta Pro Ultra rising to $5,799, the Smart Home Panel 2 selling for $1,899, and the bundle for $7,499.
