EcoFlow DELTA Pro Ultra Review – Everything You Need to Know!
Today at The Solar Lab, we’re taking a look at the highly anticipated successor to EcoFlow’s incredibly popular EcoFlow DELTA PRO – the EcoFlow DELTA PRO ULTRA. From our initial skepticism to the results of our own tests, this review will cover absolutely everything you should know about the DELTA PRO Ultra.
Spoiler alert: as always, this review is not sponsored, so you know we’re going to give it to you straight!
First Impressions: From Hate to Love
When the DELTA PRO ULTRA was first announced, we have to admit, we weren’t exactly fans. To be blunt, it looked ugly and bulky. We really thought EcoFlow dropped the ball and nobody would want to buy it.
However, once we got our hands on one and could see the thing in person, our thoughts completely flipped. Through everyone else's cameras and EcoFlow’s own promo pictures, it looked meh. In person? This thing is a beast. It looks far less bulky, and actually has a pretty slick appearance.
It's clear now what EcoFlow had in mind when they designed it, and honestly, they've done the DELTA PRO name proud.
Specs and What We Liked About the ULTRA
Sure, the DELTA PRO ULTRA definitely looks better in person than it does in any of the promo pictures EcoFlow released, but that doesn’t tell us too much about it.
To help you decide if it’s actually worth your hard-earned money, here’s a breakdown of the ULTRA’s specifications, features, performance, and what impressed us:
The Basic Specs:
If you're at all familiar with the DELTA PRO ULTRA, you probably know a lot about its specs. But if you don’t, here’s a quick rundown:
The ULTRA was designed to function as a bit of modular-style power station, allowing users to pair the main inverter units with battery packs to create a system that works for their unique needs. The main unit boasts a built-in 7,200W inverter, and each of the attachable battery packs has a storage capacity of 6,000Wh.
Unfortunately, it's a real heavyweight in every sense of the word. The inverter itself tips the scales at 70 lbs, and each battery weighs in at a whopping 116 lbs. So, unless you’re built like Schwarzenegger, you might struggle to carry the combined unit any significant distance. Thankfully, it comes with a handy trolley, which actually really helps in this regard.
With the ability to pair up to three inverters, you can achieve almost 22kW of output power! The inverters also have a split phase feature, offering 240V directly from the front of the unit. Even though it’s primarily geared towards home backup needs, it still includes four 120V plugs, a dedicated 30-amp plug, and an L14 plug.
For input power, the DELTA PRO ULTRA supports a maximum AC input of 3,000W, and a maximum solar input of 5.6kW, expandable to 16.8kW with three daisy-chained inverters. You can also get a variety of charging accessories, like an extreme adapter or an adapter for gasoline generators.
Each inverter can handle 30kWh of battery capacity, allowing you to stack up to five 6kWh batteries for a total of 90kWh. Talk about serious power!
Ports and Connectivity Galore:
EcoFlow didn’t skimp on ports when they designed the ULTRA. It includes two USB-A, two USB-C, an Anderson port, a low voltage solar port, a ground screw, an AC input, and a high voltage PV input.
The input and output ports are neatly hidden behind little doors, complete with specs printed on the inside to prevent any accidental overloads. This level of attention that EcoFlow clearly put into designing this thing was totally lost on us before we got to see it in person.
Preconditioning Feature and Noise Levels:
One of the coolest features we discovered during testing is the ULTRA’s preconditioning capability, which is similar to what you get with a Tesla. Basically, this allows the battery to warm up ahead of time and accept more power at an even faster rate when plugged in.
Speaking of plugging it in, the ULTRA is also surprisingly quiet, especially when you consider the fact that it was designed for whole-home backup purposes. Even when we tested it under a heavy load, it barely made a sound. Perfect for RV use, or, as EcoFlow almost certainly had in mind, any at-home scenario where noise would be a concern.
Smart App and Automation Features:
The ULTRA has an improved display over its predecessor. The updated screen is brighter and easier to view, and it has a simple and clean layout.
Unfortunately, the accompanying smart app hasn't seen much of a refresh. However, you can now control charging speeds and set automations for AC charging, AC discharging, and DC-only discharging. This opens the door to peak shaving, which can save you money by allowing you to charge the batteries during off-peak hours and use the stored energy during peak hours.
With rising utility rates, these features are huge!
What We Didn’t Like About the DELTA PRO ULTRA
Like anything, the DELTA PRO ULTRA isn’t without its faults. Since we always want to give you the most accurate information possible, here are a few things we didn’t like:
Direct 240V Output and Connectivity Concerns:
One of the standout features is the direct 240V output, eliminating the need for a dual voltage hub like the original DELTA PRO. However, the new connections mean that accessories from previous models aren't compatible, which is a bit of a bummer.
This isn’t the end of the world, especially for those who are okay with buying from scratch, but it would have been really beneficial for those already running an EcoFlow DELTA PRO.
Solar Input Limitations:
Despite being designed primarily for home backup, the DELTA PRO ULTRA’s solar input is limited to just 5.6kW. This might not be sufficient for some users, especially since EcoFlow itself doesn't sell it paired with panels. If you don’t already have a solar array, and you want everything in one convenient package, you may need to look at one of the third party sellers that will feature the unit as part of a complete kit, like you get with Shop Solar.
So, who is the DELTA PRO ULTRA For?
At first, it wasn't clear to us who this unit was designed for. After playing around with it and running a few tests, we started to get what EcoFlow was aiming for. If you’re willing to shell out for a few batteries and an adequate number of solar panels, it can be a serious game-changer for the home backup market.
It simplifies the process of setting up a home backup system, offering a one-and-done solution. No need for multiple products or extensive knowledge about solar power systems. Plus, it may be heavy, but it’s still technically portable, so it can come with you if you own multiple properties, or even plan on moving in the future.
Despite the overwhelming number of positives, it does come at a fairly steep price. A setup with one inverter and three batteries costs in the ballpark of $12,400, which is comparable to a 15kW solar kit with panels and accessories for $13,500. So, the decision boils down to whether you prefer a plug-and-play solution, or a more customizable (and potentially cost-effective) permanent solar setup.
If you just need basic backup power and portability, we’d probably lean more towards a more budget-friendly alternative, like the previous version of the DELTA PRO or the Anker SOLIX F3800 Power Station.
Final Thoughts
If you love DIY projects and getting the most bang for your buck, a full residential solar power kit might be the way to go. But, if you want a hassle-free, innovative solution, the EcoFlow DELTA PRO ULTRA is actually a pretty incredible option. It’s silent, powerful, and incredibly user-friendly.
Overall, it gets two thumbs up from us.
