EcoFlow enters the Home Battery Storage game, introducing the DELTA Pro Ultra

    We’ve reviewed EcoFlow portable battery products on techAU before, but at CES 2024, they announced a new product that takes their product lineup into a whole new category. The DELTA Pro Ultra is the world’s most powerful smart hybrid whole-house battery generator and backup system.

    EcoFlow DELTA Pro Ultra is a residential power backup system designed for both extended outages and daily use. With an unrivalled single-unit capacity of 6kWh, 7200W output and 5.6kW of solar input, it can run an entire home.

    The stackable design allows for quick expansion of storage and output. While its compatibility with a variety of energy sources, including solar and gas, caters to a wide range of power needs.

    EcoFlow is also launching Smart Home Panel 2, offering an easy way to fully integrate Delta Pro Ultra with any home for a quick grid-to-backup transition with auto switch-over. It also optimizes energy use, reducing costs and extending backup through intelligent analysis and solar utilization.

    In the face of increasing energy insecurity due to grid failures and extreme weather, we have developed DELTA Pro Ultra along with Smart Home Panel 2 to address these challenges. We aim to empower individuals with the freedom to choose the best power solutions in daily use for their households and give them peace of mind during power outages.

    Whole-home power for up to a month

    EcoFlow DELTA Pro Ultra is a flexible solution providing essential power to fit a range of consumer needs. Whether intended for daily use or to prepare for the unexpected, DELTA Pro Ultra boasts an unrivalled capacity from 6kWh to a massive 90kWh – enough essential whole-home power for two days to a month (or to fully charge your EV, something generally not available from home battery storage).

    With 7,200W output, a single unit can run your entire home, including large home appliances like HVAC systems. When combined with EcoFlow’s new Smart Home Panel 2, the system can be scaled up to 21.6kW of output, enough to power the largest, most demanding households.

    The DELTA Pro Ultra can be charged through AC power, solar panels and gas generators, offering maximum flexibility and extended backup time. This creates a highly resilient energy solution, providing users with peace of mind in any scenario. For solar users, the DELTA Pro Ultra seamlessly integrates with both existing rooftop solar systems and flexible solar panels, featuring solar input from 5.6kW up to 16.8kW.

    Safe and reliable with a 10+ Year Lifespan

    EcoFlow DELTA Pro Ultra ensures uninterrupted power switchover in as little as 0ms for devices directly connected to the inverter, safeguarding vulnerable electronic equipment 24/7. When paired with Smart Home Panel 2, it delivers a fully automated whole-home switchover in under 20ms, ensuring a seamless transition during power outages.

    A robust battery management system ensures DELTA Pro Ultra’s safety and longevity. The inverter features EcoFlow’s patented X-Cooling technology, utilizing a groundbreaking heat-dissipating system that increases efficiency by 50%, reduces noise and extends component lifespan. Its EV-grade LFP battery chemistry allows for over 10 years of daily use, with 3,500 discharge cycles before reaching 80% of original capacity.

    Uninterrupted backup, Advanced Energy Management and lower power bills

    With Smart Home Panel 2, users can experience uninterrupted power backup with automatic switchover, energy consumption monitoring, charging scheduling and lower electricity bills – all controlled via the EcoFlow app. The panel provides 12 loads of circuit-level control for managing individual appliances separately, offering complete access to whole-house energy usage.

    The intelligent Storm Guard feature, powered by Weatherbit, automatically monitors weather systems to prioritize power backup in case of an approaching storm.

    Easy installation

    EcoFlow DELTA Pro Ultra was designed for simplicity and accessibility. It’s ready to use straight out of the box, and is part of an open ecosystem that can grow and evolve to meet our customers’ changing demands over time.

    For a simple home connection, a transfer switch or inlet box is all you need. Alternatively, for a comprehensive solution, installing EcoFlow Smart Home Panel 2 is as straightforward as adding a sub panel – a task manageable for any electrician.

    EcoFlow DELTA Pro Ultra is also suitable for off-grid power solutions, thanks to its modular and portable design, including RVs and tiny homes. Neither the battery nor inverter require permanent wall mounting and can be transported for camping, tailgating and other outdoor activities.

    Intelligent and integrated home energy future

    As an industry leader, EcoFlow is pioneering the integration of commercial-grade and electric vehicle technologies into home energy solutions for the first time.

    Harnessing the power of four foundational technology platforms — Energy Charging and Discharging, Energy Expansion Technology, Smart Energy Management System Platform, and Safety Technology Platform — EcoFlow is dedicated to elevating the energy experience for its customers through unparalleled in-house innovation.

    For instance, EcoFlow DELTA Pro Ultra, featuring Energy Expansion Technology, provides users with extensive customization options, allowing them to harness energy from various sources such as the grid, solar and gas. We see it is the starting point for a whole realm of possibilities.

    said Brian Essenmacher, EcoFlow’s head of North American business development.

    Looking ahead, these technologies will converge to deliver a fully integrated, cloud-enabled energy experience. Users can effortlessly manage power generation, allocation, storage and appliances across EcoFlow and third-party devices through intuitive web and app interfaces.

    Price and availability

    EcoFlow DELTA Pro Ultra will be available starting Jan. 9 on the EcoFlow website and

    On EcoFlow website, users can purchase DELTA Pro Ultra (inverter and battery) for US$4,999, and the Smart Home Panel 2 is available for purchase at US$1,599.

    This is also available as a bundled package with DELTA Pro Ultra for US$6,399 until February 9, after which the prices will be US$5,799 for DELTA Pro Ultra, US$1,899 for Smart Home Panel 2 and US$7,499 for the DELTA Pro Ultra bundle.

    There’s currently no word on Australian availability, but I hope they bring this solution down under. In Victoria, Solar Victoria offers interest-free loans to add battery storage to your home. There are currently 2,817 grants remaining, from a total of 4,500 that allow up to $8,800 off the price of the battery.
