Hands On With the EcoFlow Delta Pro

EcoFlow Delta Pro Unboxing And First Impressions


The EcoFlow DELTA Pro Ultra is a robust, efficient, and versatile solution for whole-home power backup. Its capacity, high-powered output, solar input efficiency, and advanced features make it a reliable choice for maintaining power and achieving energy savings. The integration of frequently asked questions provides additional clarity, showcasing the DELTA Pro Ultra as a formidable solution in the face of increasing power challenges.

EcoFlow DELTA Pro Ultra vs. EcoFlow DELTA Pro and the Market: A Comprehensive Comparison

EcoFlow Delta Pro vs. Delta Pro Ultra

When it comes to ensuring power stability at home, particularly during outages, the market is bustling with options. EcoFlow, a key player in the portable power station field, has introduced two notable products: the EcoFlow DELTA Pro and its more advanced sibling, the EcoFlow DELTA Pro Ultra. Each unit is designed to cater to the escalating demand for reliable and sustainable backup power solutions. In this article, we compare the DELTA Pro Ultra with the DELTA Pro and examine how it stacks up against the broader market.

Deltra Pro Ultra & Delta Pro Capacity and Power Output

The EcoFlow DELTA Pro Ultra marks a significant leap from the DELTA Pro, with a base capacity of 6kWh, almost double that of the DELTA Pro’s 3,600Wh. The DELTA Pro Ultra’s power capacity is not just a marginal improvement; it’s a game-changer for homes requiring longer-term backup power, capable of scaling up to a staggering 90kWh. On the other hand, the DELTA Pro can also be expanded, but only to a lesser extent, allowing users to combine two units for a total of 7.2kWh and four batteries for a total of over 21kWh.

In terms of output, the DELTA Pro Ultra offers a baseline of 7200W AC output, significantly more than the DELTA Pro's 3000W. The Pro Ultra can also peak at 10.8kW for short bursts, ensuring it can handle surges from high-demand appliances. When it comes to voltage, the DELTA Pro Ultra naturally delivers 120V and can output 240V, similar to the DELTA Pro when two units are combined. However, the Pro Ultra stands out with its ability to triple the inverters for an incredible 21.6kW AC output, a feature the DELTA Pro cannot match.

Ultra Vs. Pro Solar Input

Solar input capacity is a critical measure for backup power systems, especially for eco-conscious consumers aiming for energy independence. The DELTA Pro Ultra boasts a 5.6kW solar input, extendable to an exceptional 16.8kW with additional hardware. This means that the Pro Ultra can potentially harvest an entire day’s worth of energy in just one hour of sunlight. The DELTA Pro, while impressive in its own right with the ability to use solar energy, doesn't reach the high solar input levels of the Ultra version.

Delta Pro Ultra Connectivity and Compatibility

The DELTA Pro Ultra and the DELTA Pro share several connectivity features. Both can be connected to a home through an inlet box, transfer switch, or the EcoFlow Smart Home Panel. However, the Pro Ultra enhances the experience with the Smart Home Panel 2, offering a more sophisticated energy management system that includes rapid automatic switchover and the ability to prioritize specific circuits.

Market Comparison Vs. The EcoFlow Delta Pro Ultra

When comparing the EcoFlow DELTA Pro Ultra to other products on the market, its most direct competitors come from brands like Tesla with their Powerwall and Generac with their PWRcell. While the Powerwall and PWRcell offer similar scalability and integration with home energy systems, the DELTA Pro Ultra often surpasses them in terms of rapid scalability and flexible energy input options, including solar, AC, and even generators.

A notable market advantage of the DELTA Pro Ultra is its portable design. Unlike the typically stationary nature of the Powerwall or PWRcell, the Pro Ultra offers a degree of portability that allows it to be used in a variety of settings, not just fixed to home use. This adaptability is a significant selling point for users who need backup power on the go or for outdoor activities.

Delta Pro Ultra User Experience and Convenience

The DELTA Pro Ultra is designed with the user experience in mind. The integration with the EcoFlow app allows for a seamless interaction with the device, offering monitoring and control capabilities that are intuitive and user-friendly. While the DELTA Pro also works with the EcoFlow app, the Pro Ultra's enhanced features, such as detailed energy consumption monitoring and more outlets, provide a more comprehensive and sophisticated user experience.

Warranty and Longevity

The warranties provided by EcoFlow are competitive within the market. The DELTA Pro Ultra comes with a 5-year warranty, with its batteries expected to last for up to 10 years, echoing the longevity of its competitors. The DELTA Pro also has a robust warranty, though the Pro Ultra's longer-term assurance is likely to be more attractive to consumers seeking a long-term investment.


The EcoFlow DELTA Pro Ultra is not just an upgrade from the DELTA Pro; it's a statement product that challenges the market. With double the base capacity, a significantly higher power output, and an advanced solar input capability, the Pro Ultra positions itself as a leader in the home backup power segment. Its smart connectivity and user-friendly design, coupled with the ability to meet diverse energy needs, make it a formidable competitor to household names like Tesla and Generac.

For consumers, the choice between the DELTA Pro and the DELTA Pro Ultra will come down to their specific power needs and budget. For those seeking the most robust, expandable, and versatile backup power solution, the DELTA Pro Ultra presents a compelling case. It represents a shift towards more resilient, adaptable, and user-centric home energy systems, setting a new benchmark for the industry.
