Quick Overview: EcoFlow Delta Pro Ultra

Home backup power used to be challenging, requiring extreme customization and an array of expensive equipment. EcoFlow has been fiercely pushing against this standard to create a simple home backup system beyond anything else around.

The EcoFlow Delta Pro Ultra (DPU) is the brand’s most powerful and advanced system yet, entering the uncharted territory of user-friendly home backup systems. Yet the Delta Pro Ultra remains a portable unit that isn’t anchored to your home.

You can bring your home backup system on adventures and use it as an electrical powerhouse on wheels. If you move, it can come to your new home and provide years of stable backup power and lower energy bills.

The ground-breaking features of the EcoFlow Delta Pro Ultra include:

1. Seamless home integration through multiple high-amp options
2. Modular system can grow with your needs and budget
3. Extreme battery capacity from 6kWh to 90kWh
4. High-performance inverter with 12kW per inverter, up to 21.6kW total
5. Powerful charging inputs can accept up to 16.8kW of total solar (5.6kW per inverter unit)

We’ll translate these specs into words you can understand below. Rest assured that these figures blow competitors away and surpass many fully customized systems.

As far as value and price are concerned, the EcoFlow Delta Pro Ultra is an excellent value compared to other portable power stations. When you equalize prices by comparing the price per battery watt-hour, it falls around $0.90 per Wh or lower usually (depending on current prices/sales). That’s aligned with the best options from other brands like Bluetti and Anker. However, this EcoFlow surpasses almost every single alternative in capabilities. So you get more power and features while paying about the same per Wh price.

It’s no secret you can build DIY solutions for less money. But that’s not always the case when you include every tool, every connection, and every hour spent figuring it out. And it’ll never be as portable, it’ll never have the warranty coverage, and it’ll never have as seamless of a home integration with full app monitoring and control of this EcoFlow model.

The EcoFlow Delta Pro Ultra is the best power station on the market. It’s the most capable system that allows a portable power station to match specs possible with the best custom home backup systems. EcoFlow has put it through the wringer, ensuring high-quality engineering and craftsmanship, backed by an extensive 5-year warranty and knowledgeable support staff.

In-Depth Review: EcoFlow Delta Pro Ultra Capabilities

We’ve done a quick overview of what this heavy-duty power station can handle. Now let’s check out the details to verify it’s the right solution for your needs or if you should look elsewhere.

After this, we’ll also closely review how to connect the Delta Pro Ultra to your home and comparisons to other power stations and products.

Here’s how we’ll go over this in-depth review of the Delta Pro Ultra:

• Battery Specs: How Long Can It Provide Power?
• Inverter Details: How Much Power Can It Deliver At One Time?
• Charging Speeds: How Quickly Can You Recharge It?
• Other Features: Setup, App, and Maintenance
• Weight and Dimensions: Can You Move It?
• Our Recommendation: Is the Delta Pro Ultra Worth It?

DPU Battery: The Heart of the Backup System

The Delta Pro Ultra features a modular system, with a main inverter unit that can have up to 5 external batteries attached to it. Three main units can work together, allowing up to 15 batteries. It can power your home for a very long time, hours at minimum and weeks at most – without any charging.

Each DPU battery has a substantial capacity of 6,144Wh. The individual battery can charge a phone more than 500 times or run a home refrigerator for around 30 hours. If pushed hard with a 1,500W air conditioner (one of the most power-hungry household appliances), it would still last nearly 4 hours from just one battery.

And that’s just the starting point. The maximum system with 15 batteries takes it to 90kWh, enough to power most households for many days and in some cases, weeks.

To calculate exactly how long the Delta Pro Ultra will power your devices, there’s a simple formula to use. Take the battery Wh you plan on getting, then divide by the total wattage of the devices you want to run. Take off 20% due to normal inefficiencies (think heat loss, wiring voltage drops, inverter consumption). Wh / W x 0.08 = Estimated hours of runtime.

Here’s how you can estimate the wattage of your devices:

• Utility Bill: Use the monthly kWh details from your home energy bill and divide by 30 days to see how much energy you use in one day.
• Watt Meter: Plug your devices into this meter for a day or two and see how much energy they use.
• Manual Calculations: Find the running wattage (not peak) for each device you want to use and add them together. Using rough estimates and common figures can provide very useful data, such as:
  • 10W to 100W: Phones, tablets, laptops, WiFi routers, LED lights, small fans
  • 200W to 500W: Large televisions, desktop computers, full-size refrigerators
  • 1,000W to 2,000W: Coffee makers, microwaves, induction cooktops, hair dryers, power tools
  • 3,000W and up: Whole-home air conditioners, heavy-duty electrical appliances

For example, you can power a handful of small devices, a large TV, and a full-size fridge while only reaching around 500W total power use. That’s 500Wh per hour. One Delta Pro Ultra battery with 6.14kWh will last almost 10 hours!

The EcoFlow Delta Pro Ultra battery is built with Lithium Iron Phosphate (LFP or LiFePO4) cells, known for its safety, longevity, and stability. It maintains over 80% of its original capacity after 3,500 charging cycles, typically providing about 10 years of exceptional service. It can still be used after that, it just won’t hold as much of a charge. It’s one of the best off-grid batteries, without a doubt.

The EcoFlow Delta Pro Ultra’s battery is powerful, durable, and dependable. It stands at the core of your energy resilience with one battery unit providing many hours of whole-home backup power. To run heavy-duty devices or ensure you have longer time without a power source, you can stack on up to 15 batteries in total. The Delta Pro Ultra battery capacity is out of this world.

The Inverter: How Much Power Can It Deliver At One Time?

The EcoFlow Delta Pro Ultra’s inverter stands out as a cornerstone in the realm of portable energy solutions. Each unit boasts a continuous 7,200 watts of pure sine wave AC power, ensuring a clean and stable output that’s gentle on your most sensitive electronics.

If you’re not familiar with how inverters work with solar panels and batteries, they convert direct current (DC) electricity from batteries and solar power into alternating current (AC) electricity for household use. It is one of the most important parts of the power station. Without the inverter, you would not be able to connect your home circuits or any device that requires AC power (120V or 240V).

If you’re using smaller devices or have a DC fuse box to power, the Delta Pro Ultra includes:

• 4 USB Ports
• 1 30-amp DC output

These are ideal for small power needs and they let you conserve a bit of energy by avoiding the inverter. Yet the DPU is not primarily designed for this use. It’s so powerful it would almost be a shame to limit your use to these ports.

The larger the inverter rating, the more electricity it can provide at one time. If you connect too strong of a device or too many devices at one time, you can go over the inverter’s limits. Then it doesn’t matter how much energy is stored in the battery. It can’t flow as it needs and your devices won’t stay powered.

It’s also important to be aware of the startup surges some devices have. If you want to power things like a larger air conditioner, those can have very large power needs for a split second when they start. Soft start devices can help mitigate this, but you’ll still want to get an inverter that’s well over the running wattage needs.

A single Delta Pro Ultra unit can confidently run everything from your kitchen appliances to your home office setup without missing a beat. However, it might struggle if you want to use multiple high-watt devices simultaneously. Or if you have an entire house of small devices then want to crank on the air conditioner. The DPU comes with multiple 30-amp outputs delivered at either 120 or 240V.

One outlet on the DPU has an online uninterruptible power supply (UPS), meaning it switches over with no delay (0 ms) so computers can keep running. This single unit will have no problem with multiple televisions, lights, a refrigerator, and even an air conditioner – all at the same time.

The true potential of the Delta Pro Ultra is unlocked when units are combined. The maximum system uses three DPUs.

Two units double your power capacity to 14,400W and allow for a 50-amp split-phase connector, a fancy term for a special power strip. This helps support larger appliances and more demanding environments, such as larger households. It can comfortably power heavy-duty electricals running at the same time, such as an electric oven, induction stovetop, and more.

Many people will hit the sweet spot with two DPU units. This is our common suggestion if you’re looking for whole-home backup.

For those requiring a very intensive power solution, linking three units escalates the total output to a formidable 21.6kW (21,600W). This caters to serious power needs while also allowing more battery support. It creates whole-home systems for extended blackouts and exceptional energy resilience.

With such versatile configurations, the EcoFlow Delta Pro Ultra’s inverter not only promises reliability but also offers scalable solutions tailored to a wide range of power needs. While one DPU unit offers 7.2kW of output, you can link up to 3 units to get 21.6kW in total of AC output power. Most households will have a very hard time maxing out this three-unit system.

Charging Speeds: How Quickly Can You Recharge It?

The charging capabilities of the EcoFlow Delta Pro Ultra are engineered for flexibility and speed. You can harness and store energy efficiently, no matter the source. This can extend your runtime during power outages and save you money by utilizing off-grid charging sources.

AC Charging

For AC charging, the DPU supports 120V at 15A, which is the standard output of most AC outlets. It can also jump up to 240V at 12.5A, a more powerful source common with appliances like dryers. And it has a bypass mode for simultaneous AC charging and AC output. 

If you can max out the AC input, you can charge one DPU battery in about one hour (depending on how much the BMS protection steps in to avoid damage).

You can keep it fully charged while also powering devices. The uninterruptible power supply (UPS) feature that kicks in instantly when power cuts out. Your devices keep running even if the AC charge cuts out.

Solar Charging

The EcoFlow Delta Pro Ultra solar panel input offers an incredible range, with one high-voltage input and one low-voltage input on each DPU, for a total of 5,600W of solar panels.

The high-PV input accepts 80 to 450V at up to 15A, allowing a maximum of 4,000W. It’s ideal for efficiently converting sunlight collected by larger, more powerful solar arrays. The low-PV input can support smaller panels with 30 to 150V at up to 15A, maxing out at 1,600W. This range ensures that even with fewer panels or lower solar conditions, the unit can still effectively gather and store energy. No matter your solar setup, the DPU can handle it.

Here is how many EcoFlow solar panels each input can handle:

• EcoFlow 220W Bifacial Portable Solar Panel
  • Low-PV input: 2 to 6 of these panels
  • High-PV input: 5 to 6 of these panels
• EcoFlow 400W Portable Solar Panel
  • Low-PV input: Only 2 panels at most
  • High-PV input: 2 to 8 panels 
• EcoFlow 400W Rigid Solar Panel
  • Low-PV input: 2 to 3 panels
  • High-PV input: 3 to 10 panels

All of these configurations depend on series connections where you connect the negative of one panel to the positive of another, creating a series string to connect to the DPU which increases the voltage. 

You can also use other brands of solar panels, you just need to make sure the voltage stays within the maximum for each input. This solar panel calculator can help determine how many panels you need.

We also have a hands-on wizard that uses the specs of the power station and solar panels to ensure you maximize solar charging without exceeding your power station’s inputs. It even accounts for temperature drops, which can have a large impact on voltage (volts rise when temps drop).

Fuel Generators

Although we prefer to point people toward solar panels, fuel generators can provide another source of backup power. When major storms roll in, that’s not the time you want to rely on sun power. Nor is it the time you want to run out of power.

A backup fuel generator can offer big bursts of charging for your DPU. You still get a lot of benefits from using the Delta Pro Ultra with a fuel generator because you don’t have to leave the fuel generator on too long. You just charge the battery and then shut it off, using hours of silent battery power from a short (noisy) charging boost from a fuel generator. The inverter power of the DPU also is far above most fuel generators.

Having a dual fuel generator, including EcoFlow Smart Generator, can be especially useful. Use gasoline when convenient or switch to propane which is easier for long term storage. Our only complaint is that the EcoFlow Dual Fuel Generator’s smart features do not work with the DPU due to its different battery voltage than the power stations it is designed for (like the Delta Pro 3).

There are other ways to generate off-grid power, but solar and fuel generators are usually the most convenient.

Overall, the EcoFlow Delta Pro Ultra has incredible charging inputs. The solar input specifications allow for extensive solar panel usage, generating many thousands of watt-hours of energy every sunny day. The AC inputs are super-fast, absorbing all the energy you can throw at it. You will not find a better power station as far as charging specs go.

Other Features: Setup, App, and Maintenance

The EcoFlow Delta Pro Ultra is designed for simplicity and efficiency, ensuring a seamless user experience right from the start. Here’s what makes it a standout choice:

• Quick Setup: Unbox, place it in the location of choice and connect the charging cable to top off the battery. Then connect one high-amp cable from the DPU to your transfer switch (like the Smart Home Panel 2) and you’re ready to go, with no complex procedures. Or just plug your devices directly into the variety of outlets on the DPU.
• Smart Control with EcoFlow App: Puts control at your fingertips. Monitor energy use, adjust settings remotely, and stay updated with automatic software enhancements, all from your smartphone connected wirelessly. It connects through WiFi and Bluetooth, plus has a 4G independent connection too.
• Minimal Maintenance: Regular checks for cleanliness and secure connections keep the Delta Pro Ultra running smoothly, while built-in safety features protect against common electrical issues.
• Troubleshooting Made Easy: Most use is trouble-free, but if anything comes up or you need help with a tricky situation, customer support is a call or click away. A thorough user manual and app assistance provide a lot of detailed information too. As does the large EcoFlow customer community.
• Ready for Upgrades: Add solar panels, extra batteries, or another DPU unit easily, allowing your home backup power system to grow as your needs and budget allow.

Managing your DPU power supply is hassle-free, smart, and adaptable. Every Delta Pro Ultra is packed with the features you need to be able to use it easily and without a hassle. EcoFlow has designed one of the best systems that nearly anyone can use. No tech-savvy experience is needed, but if you want to go crazy with special settings, you can.

Weight and Dimensions: Can You Move It?

One of the greatest things about portable power stations over DIY options is that they are actually portable. And even though the EcoFlow Delta Pro Ultra is one of the largest and most capable power stations ever, it’s still incredibly portable.

Each DPU inverter unit only weight 70 lbs (32 kg). You can stack up to 5 batteries and put that entire system on a wheeled cart.

While you’re most likely going to leave this system stationary most of the time, you can bring it on a road trip, to an event, or when you move to a new home. Compared to other DIY systems, this ability provides excellent value. You can trust that your DPU will be there whenever and wherever you need it most.

The EcoFlow Delta Pro Ultra excels in portability. By separating the battery units from the inverter units, it retains a manageable weight. And no matter where or when you need portable power, you can bring this heavy-duty power station along for the ride. Set up large events anywhere. Be the king of the campground. Or be ready to move to a new house without leaving expensive gear behind.

How to Connect the Delta Pro Ultra to Your Home?

There’s no limit to how you can use the EcoFlow Delta Pro Ultra. Thanks to its massive battery banks and ultra-powerful AC inverter, it can power nearly any device including an entire home. More details on these parts and how long this EcoFlow power station can run your devices or home further below.

The easiest way to use a Delta Pro Ultra is just to plug your devices directly into it. The DPU has outlets that can accept everything from a small USB charger to heavy-duty appliances. 

However, you can get the most out of this device by integrating it with your home circuits and creating a home battery backup (or an off-grid solar system). The DPU’s electricity flows directly through your existing outlets, keeping your entire home powered up through any emergency. It can also cut energy costs by using battery power during peak hours.

You can connect the EcoFlow Delta Pro Ultra to your home’s electrical system through any of these options:

• EcoFlow Smart Home Panel 2 (with integrated critical loads subpanel)
• Generic transfer switch and critical loads panel
• Generator inlet box

Most Advanced: EcoFlow Smart Home Panel 2

The EcoFlow Smart Home Panel 2 offers seamless integration with maximum automation, control, and monitoring. This is an intelligent subpanel that combines a critical load 12-circuit panel with an advanced automatic transfer switch, all made specifically for the DPU. 

After a straightforward installation that shouldn’t take more than a few hours, your home will automatically switch to the backup power from the DPU in less than 20 ms during a power outage, faster than the blink of an eye. You can also set a schedule for it to switch to the DPU’s battery power as you wish, lowering the cost of your utility bill and reliance on grid power.

The Smart Home Panel 2 connects to the sleek EcoFlow app, giving you unrivaled control and monitoring. It works whether you’re steps away in your home or on the other side of the globe. This advanced transfer switch is the way to get the most out of your EcoFlow Delta Pro Ultra as a home backup battery system.

Those looking for the best way to use the EcoFlow Delta Pro Ultra will always reach for the EcoFlow Smart Home Panel 2 automatic transfer switch and critical loads panel. It’s the dream team combo that creates the ideal connection between this heavy-duty portable power station and your home circuits.

Increased Flexibility: Generic Transfer Switch and Critical Loads Panel

If you prefer a more universal approach with a standard connector (instead of proprietary EcoFlow connectors), you can use the EcoFlow Delta Pro Ultra with a common transfer switch and critical loads panel from other brands. Many options integrate both functions into one subpanel just like the Smart Home Panel 2.

You can find automatic transfer switches that will change from grid power to battery as needed without your intervention. Or you can use more affordable manual transfer switches where you must physically change the setting from grid power to battery backup. It’s not quite as convenient, but it keeps costs down.

The DPU has two 30-amp outlets that you can use to power a regular transfer switch and critical loads through a matching 30-amp input. Or you can join two DPUs together to create a 50-amp output to match a higher-powered transfer switch.

Although not quite as impressive as the EcoFlow Smart Home Panel 2, the EcoFlow Delta Pro Ultra will work with a wide variety of universal transfer switches. Two of our favorites are the Generac Automatic Transfer Switch with 200-amp capacity and the trustworthy Reliance Controls 306CRK Transfer Switch Kit with a 30-amp connection or the Reliance Controls 510C 50-Amp Manual Transfer Switch. These two brands, Generac and Reliance, are also reputable brands you can rely on.

Cost-Focused Simplicity: Generator Inlet Box

The cheapest way to use your DPU is through a basic generator inlet. This is a simple high-amp input added to your existing home panel, allowing an external generator to power home circuits when the main power supply is cut off. It should come with an interlock device that prevents simultaneous grid power and backup power (which could backfeed the grid and pose danger to others).

Most experts prefer the extra safety from a separate critical loads panel and transfer switch. It also means you’ll need to flip off or not use the circuits that will overload your Delta Pro Ultra, unless you get enough DPU power to handle your entire home.

But if you don’t mind a more hands-on manual approach and are aware of the risks (including the potential of overloading neutrals from any adapters), a generator inlet box is a very simple and low-cost way to attach any generator to your home circuits. But it’s best for limited use for those with the right knowledge. The transfer switch is a better option for most people.

No matter which way you go, you can use the EcoFlow Delta Pro Ultra as the home backup power of your dreams. Lower your energy bills and discover the confidence to power through emergencies as the neighborhood goes dark.

Delta Pro Ultra Comparisons to Top Brands

To make sure it’s the right choice, let’s quickly compare the EcoFlow Delta Pro Ultra to other power station alternatives, including:

• Less powerful EcoFlow power stations
• Competitor power stations from brands like Bluetti, Jackery, and Anker
• Custom home backup solutions

Before the Delta Pro Ultra was released, the Delta Pro (not Ultra) was the king of the EcoFlow mountain. It is a similar modular power station system with extra external batteries. While it has a lower cost, it comes with less impressive specifications across the board (max 25kWh battery and 7.2kW AC output). If that’s within your desired power limits, then you can save cash by going with the EcoFlow Delta Pro instead of the DPU.

EcoFlow has more recently introduced the EcoFlow Delta Pro 3, a major improvement on the lower model. It can go up to 12kW total inverter output with three DP3 units and 37kWh when you max out the battery capacity. If these specs are within your needs, the Delta Pro 3 might be the right call.

Many other brands have power stations capable of home backup use. But none of them have the near-perfect design of the EcoFlow DPU, nor do they come close to the DPU’s maximum specifications. 

The options that are closest to the DPU include the Bluetti EP900 and AC500, as well as the Anker F3800. We have listed a summary of the spec comparison chart below for your reference. These all have lower maximum capabilities and the EP900 isn’t a true portable power station.

While we like some Jackery, Zero Breeze, Mango Power, and BougeRV power stations for other needs, they don’t quite make the cut for this category. You can read more about the details in our full breakdown of the best power stations for home backup use.

The other Delta Pro Ultra alternatives for home backup power are customized systems, which can be done through various approaches:

• The easiest and cheapest is to use a fuel generator through a generator inlet box, which has no battery bank.
• The most complex is to have a charging input for each source (generator, solar, grid) connected to a custom battery bank and power inverter.
• Hybrid inverters help simplify the system in some ways by combining chargers, inverter, and transfer switch. But it’s still a permanent installation that requires a custom battery bank and many expert-level connections most DIYers don’t risk doing themselves.

These custom solutions used to be the only way to go. But the Delta Pro Ultra provides nearly the same functions in a plug-and-play portable system that is amazingly easy to use, monitor, and control. These custom options require:

• Serious electrical knowledge and skill to create and install
• A heap of different products and devices that must be professionally connected
• A permanent installation for a system that cannot move and will take up significant space
• Significantly more difficult trouble-shooting since you have a one-off system

These systems have the benefit of potentially cutting costs and offering the flexibility to meet your needs with extreme precision. 

You might think of this like you would buying a computer. Some people choose to buy individual components to build an impressive home desktop. While you could pay someone to build a one-off computer like this for you, most people choose to buy a well-built system from a reputable brand, often a laptop. 

Not too long ago, home power systems could only be like building a custom desktop system. This EcoFlow DPU is changing the landscape, offering a laptop-like solution that can be just as powerful as the custom desktop.

EcoFlow is like the Apple of the power station world, providing a premium product with the most user-friendly experience on the market. And the EcoFlow Delta Pro Ultra is the most powerful and capable option on the market.
