I am not am expert in batteries but more a novice. Instructions were brief but tell you pretty much everything you need to know. It is heavy. wheels are a good idea! It is a very high quality device. No question about that. The support team was excellent and they respond quickly. The feature that tells you how much time you can run a device that is plugged in is worth the price.. I ran the garage freezer for 3 days. I had no problem using a wolf oven, bread maker and my computer workstation. I have had lesser batteries but when you are so limited in what you can run, you end up not using them. Worth the price tag.
I would recommend this to a friend!

Quiet and capable home backup power!

I live in a rural area and suffer through at least a few multi-day outages every year. The worst one was during an ice storm right before Thanksgiving a few years ago that left us without power for a week and a half. Coming home to what feels like a cold campsite daily living off whatever you can make on a natural gas cooktop and warming yourself by the fireplace is not my idea of a relaxing evening. Add to that, my neighbors Generac’s taunting me with their loud engines all day and night. After that, I decided that I was going to do some research on the best option and spend the money on a system so that I’d never live through that again.
I had a 10 circuit manual transfer switch installed at my home by an electrician. It allows me to plug in my 7500w gas generator or my 2 EcoFlow Delta Pros and 2 extra batteries via the dual voltage hub. This setup allows me to primarily run the quiet EcoFlow system at night and use the gas generator to re-charge my EcoFlow system during the day, or use it as the ultimate backup if needed.
I have the following on my switch: Water Well Pump, Furnace/thermostat, Garage (internet modem location), basement, bathroom, kitchen (includes fridge, freezer, cooking appliances, lights), living room (TV, work from home office), master bedroom. The EcoFlow handles all of that with no issues. During my first test day, I took a long hot shower and had my furnace cranking on a 19 degree PA night. Ran my lights, TV, internet as usual and woke up the next day with plenty of power left. Coffee was brewed and the house was warm. Obviously, during a real outage, I’d be a bit more conservative on what I use to save the batteries a bit, but the point is that it’s capable of getting you through the night and beyond.
I have tested the EcoFlow system and have found it to be able to power my home reliably and realistically for a little over 24 hours without needing to be recharged. I maintain my setup by running a monthly “fire drill”, connecting my EcoFlow system, shutting off the main breaker, turning on the transfer switch, and living as I would during an outage for a day. The next day, when my EcoFlows get down to about 20% left, I turn the main power back on, fire up my generator, and recharge the EcoFlows.
Having a transfer switch installed and using the EcoFlow combined with a gas generator IS EXPENSIVE. Even on sale, this system is NOT cheap. However, it is still slightly less expensive than what I was quoted for a Generac full home natural gas generator installation. What I like about it is the fact that you can quietly power your home at night, have multiple refuel/recharge options, and most importantly, you’re not at the mercy of the power company, natural gas company, and the Generac repairman when your expensive unit ultimately fails. This setup allows me to plug and play anything strong enough to power my switch if anything happens to fail. You can’t do that with a Generac. My area has also had natural gas issues from time to time with low/no pressure. Again, that renders your Generac useless.
I plan on buying another battery or 2 during one of the sales this year. I kind of regret not waiting for the Delta Pro Ultra to be released and buy that, but I am happy with this system. It’s disappointing that EcoFlow hasn’t made an easy adapter to connect the Delta Pro Ultra and Delta Pros. I know you can do it with the smart panel, but I already have a transfer switch that works perfectly fine. If you’re young and capable of maneuvering them and plugging things in and operating a transfer switch, this is a nice system. I’m so happy it’s on wheels! It would be nice if some of the cords, including the ones that are used to re-charge the units and the ones that connect the battery to the main unit, were longer. I am really hoping the price on this equipment continues to become more reasonable so people like me can have an affordable arsenal of backup power stored in their home for the next disaster that the power company didn’t prepare for and cannot fix in a reasonable amount of time.

Not a complete system
on December 19, 2025
Posted by: Dave 69
I purchased the EcoFlow pro series with 2 extra batteries. Also purchased the 4000 watt Smart generator. For my off grid cottage.
They are supposed to work together, especially during the short day winter weather. Big problem, I can't charge my whole system at the same time. There are only 2 ports to the Pro, so I have to sacrifice 1 battery when I charge them. PLEASE make an adapter so I can use my system in the way it was intended.

Very easy to use - great product for Central Texas

from Texas
Gender:Male
Between the snow storms we had in 2021 and the power outages due to extreme heat, I feel way more confident now with the new Delta Pro and my 400W solar panels (sold separately)
The delta pro is very easy to use as it has a beautiful Interface on the unit display and a great app for your phone. I have used my new setup already and I was able to run the Internet, TV for the kids and all our appliances virtually indefinitely.
The fast charging feature is what got me originally interested in EcoFlow. It’s ridiculously fast to charge it.

California Calamity

from Southern California
Frequency of use:Daily
Gender:Male
I live in southern California where the power company turns off electricity every time the wind blows. I run a small business out of my home with remote workers on virtual machines that I host in my server closet. My Delta Pro allows my workers to have access to their workstations whenever the power goes out. The Delta Pro is great because I can charge with solar and the smart generator meaning I can keep the servers running for more than 24 hours in any given outage. The app is powerful and allows the inverter to be set to always on preventing accidental shut off. The unit is heavy but the Delta pro has an extendable handle and rolls on wheels making it easy to move around. The features, expandability, and available accessories make the Delta Pro my favorite solar generator. I have the smart generator and the 400 watt solar panel. Build quality, shipping materials, software, and support are all excellent.

Outstanding Ecoflow products!

Gender:Male
I started with the Ecoflow Delta Pro, and after seeing the quality and the real use case scenarios, I decided to get another with the Extended Batteries as well as the Smart Home Panel. With the 22KW I can now run my fridge, freezer, lights, outlets, microwave, mini split AC unit and more for about 6 days in case of an outage! In addition adding solar panels will help top off the batteries if needed and the Ecoflow gas generator is also ready to be used if needed. Completely love everything about this system, easy to set up and works like a tank! Thank you Ecoflow!

Powers a Prevost Tour Bus!
on May 18, 2022

For those of us in the music industry, besides your music gear, your Tour Bus is the single most important part of your life while on the road - and access to POWER is a huge concern while on the go and at gigs. And in the world of Prevost Tour Buses, even though they are considered the zenith of the range, the converters making them have been VERY slow to adopt Lithium battery tech. So we took it upon ourselves to do a total electrical system conversion in ours using the Delta Pro(s) as the heart and soul.
There used to be a time when running rooftop AC units on battery power was a pipe dream, but not any longer! We're able to run 3 AC units AT ONCE with our two Delta Pro units and a single smart extra battery (we really wish we had more smart extra batteries!). When combined with the 3960 Watts of solar panels being installed on the roof of the Tour Bus we'll be using both of the DPro's 1600 watt input MPPT charge controllers to soak in all that juice and become very nearly 100% OFF-GRID in our home away from home without ever having to touch the giant diesel generator in the underbay!
To add, we've been invovled in a HUGE renovation of our Prevost, and having the Delta Pro's to power the coach while working within (the generator was shipped away for nearly a year during this process) has been a HUGE help too! They power all of our tools and run AC units at the same time letting us work inside and out without ever skipping a beat!

Power of the Delta Pro

from Houston, Texas

Gender:Male
I bought the EcoFlow Delta Pro with extra batteries and a solar panel for emergency backup mostly but it has many other uses. Recently I had a faulty circuit breaker in my home that kept popping the circuit that powers my refrigerators and freezer. Having the Delta Pro allowed me to shut down the house power and work safely on the electrical panel and allow me to troubleshoot to find the faulty breaker and have it fixed. Had my two refrigerators, one 18 cubic, the other 22cubic foot, chest freezer and a couple of lights and a floor fan, all running about 10 hours of normal use, while I had my faulty breaker replaced and had the home service panel serviced for additional problems as well. Only used about 47% of the batteries total charge and probably could have run it the following full day before it would have run out of power. Could of use this unit last year when we lost power for three day in February in Texas. That was a long three days. Now I am prepared for future power outages. Attached are photos of how I set up my unit.
