EcoFlow Delta Pro 3 Portable Solar Power Station 4,000W 4,096Wh

I bought this power station and a 400w solar panel recently, and I have to shout out Ecoflow's customer service team. Fedex misplaced one of the packages and they were very responsive and helpful! They sorted me out in under a week and I now have a fully charged power bank (the instructions were quite easy to follow!) and a solar panel to charge it. Now all I need it a power outage! :D

I had a very long run 50A generator inlet box with manual transfer switch installed a few years back during rolling blackouts before later deciding that I’d prefer a quieter easier to manage LFP battery generator. After lots of analysis paralysis, I circled back to the DP3 purchasing a dual units with 50A hub package during a sale. I routinely use the DP3’s for peak shaving and supplemental off-grid power after getting roof mounted solar. I enjoy days using 100% self-generated power.

I recently purchased the EcoFlow Delta Pro 3, and it has completely changed how I think about backup power. The 4kWh capacity and 4000W output give me confidence that I can run everything I need during an outage, from my fridge to heavier appliances. Setup was simple, and the app makes it easy to track usage. It’s heavy, but the wheels and handle make moving it manageable. For me, the peace of mind of having reliable whole-home backup is worth every penny.

I purchased this two weeks ago and the unit had damage on the box and unit with small indented scratch. Ecoflow sent a return label and I have tried to convince them to issue a small credit. I do not want the hassle of repackage and then have to wait on a new unit. Frustration with several calls and emails.

This is a powerhouse of a unit. We were struggling off-grid with deep cycle batteries and inverters to provide simple power needs. Once we got our EcoFlow Delta pro 3 we only had to run a generator maybe 1 hour out of the day. Awesome product!

I wanted something to run my pellet stove in outages and had searched for some time. This unit surpasses my hopes. Unobtrusive, looks fine in the living room and does everything advertised and worry free safety wise. It will run my pellet insert for nearly 4 days with additional outlets for anything else such as critical items like the coffee pot. Excellent quality and well thought through like being able to make all adjustments off my phone. Well done EcoFlow.

Enjoying the peace of mind knowing that I have been able to purchase this unit so that I can run it indoors

Full filling one of my “Bucket List” items I purchased the Delta Pro 3 Power Station. Why? Because, 1.) I like the physical design; 2.) I like the number of charging methodologies; 3.) I like the straight forward simplicity of use; 4.) and I like the balanced design of a 4KW inverter operating off of a 4KW battery (keeps the math simple). I’ve wired the DP3 into my home wiring using a manual transfer. The system is expanded with a DP3 Extra Battery and supplemented with solar panels and a dual fuel Smart Generator. The system is simple, effective, expandable and integrated. Doesn’t get much better than this!!

This is the first solar generator I have ever purchased.
Quick delivery. I bought one of the package deals. The ECOFlow DELTA Pro 3 with a 400 watt solar panel. I purchased it on the evening of 6/27/2024, the solar panel was delivered on 7/09/2024 and the generator was delivered on 07/11/2024 not bad since it was the 4th of July during the delivery schedule. I have been working 7 days a week so I just unpacked it last night and I’m going to set it up and start charging it tonight so I’ll update this in a couple of days. The whole unit including the solar panel seems to be of the HIGHEST QUALITY of material, cables included.
Also 2 nights ago while shopping for another 400watt solar panel, I saw the big sale they are having on the same unit, the DELTA PRO 3 so I contacted the company and they gave me a credit for $531 dollars to make up the differance from the price I paid. No hassles at all, the way it should be. Very pleased with this company so far.!!!!!!!!!!
O yea one more thing the items were packaged PERFECTLY so they wouldn’t get damaged.
Once I get the unit set up and use it I’ll be back to rate it.

I bought this last year and love it better than I could have hoped for! I use it at one of my barns with a fixed array of solar panels to operate lights and fans when I’m working on my tractor or other implements and it works great!!! Plus I have the dual fuel generator for backup if the battery gets too low from low sunlight!

As an owner of the DP3 (and formerly the DP), and as I'm leaning more and more about home backup and now journeying into off-grid migration, what a disappointment the DP3 has turned out to be. And it all comes down to one thing: The atrocious low solar input this device has. EcoFlow's release of the Delta 3 Ultra Plus has also really exposed the weakness of the DP3.

As a standalone unit, the DP3 is fantastic. Being able to provide RV camping power and LIMITED home backup power, the DP3 is quite versatile. However, EcoFlow continues to market the DP3 as an "off-grid" solution. Well, it is, but for VERY small loads due to it's lack of solar input. Meaning, if you max out the DP3 with two extra batteries (giving you 12,288 watts of capacity), at 2600 watts of solar input (more like 2000 watts realistically), it's going to take more than a perfect solar day to top off your battery bank to 100% charged. What's puzzling is that the Delta Pro Ultra was released long before the DP3, and the DPU has 600V of solar input as compared to the DP3's 210V of solar input. When you consider that the DP3 can fast charge at 7000 watts across multiple sources, why they arbitrarily decided not to include either a 3rd 150V solar input or a 450V solar input was definitely a questionable design decision. In an off-grid situation, a power station like this should be able to fully charge your maxed battery bank in 4 hours (one solar day), which, in the case of the DP3, puts that at 3100 watts (really 4000 watts max due to VoC low temperature coefficients). In other words, sure, you can power your tiny home or cabin off-grid with the DP3, but you're going to be using a metric ton of propane to keep your batter bank topped off. That's not very economical.

Now that EcoFlow has released the Delta 3 Ultra Plus (which provides a better RV camping experience over the DP3, and which also provides similar limited home backup like the DP3), and with the availability of the scalable Delta Pro Ultra and the new Delta Pro Ultra X, unless EcoFlow plans to equip the Delta Pro 4/X (whatever name the decide to call it) with a MUCH higher solar input capability, there's really no longer a need to go the direction of the DP3. And since the new Smart Home Panel 3 will not be backwards compatible with the Delta Pro 3, it appears the Delta Pro series of products has seen the end of its days. It's too bad, because I REALLY liked the DP and DP3, and where I had plans to get the Smart Home Panel (2 or 3) as I progress further into off-grid living, slowly, one circuit at a time. The DPU/X is now my targeted product to achieve this goal.

I still give this product 4 stars overall, because it IS a good unit on it's own. But as of two weeks ago, so is the Delta 3 Ultra Plus, which is much lighter, and which has a much lower price point.

EcoFlow: I love your products, and I own many of them. But in this situation, a big blunder was made.

I purchased the echo flow delta 3 for camping use. But last night we had a terrible storm and lost power for 9 hrs. I was panicking about the food in the fridge going bad. I had 87% on generator and decided to plug in refrigerator to see how it would do. It ran my huge refrigerator for 9 hours until power came back on and I still had 16% power left. I also briefly plugged in microwave to heat some food. The echo delta 3 saved thousand dollars worth of meats and foods. Unbelievable generator!! I might buy a 2nd one.

I am very well pleased with my purchse. Bought it to power tools in my shop and in case power goes out in my home. It powers most anything I need and the solar pannels are just an added bonus. Love all of it.

Very powerful. Runs everything I need it to run. Very nice made.

Finally, a generator packed with power in one unit and expandable to reach whole home emergency power endurance. Added accessory ports for versatile charging capabilities, including EV charging stations. Great reputation

I’ve done some testing on this one and it’s pretty remarkable.

The DP3 runs our well pump, refrigerator, 2 freezers , refrigerator, wifi and lights. We are pleased with the purchase!

I was overly impressed by the ease of setup and the overall capabilities of the unit. I have been using it as a backup source for two CO2 50 watt laser engravers. It has outperformed any and all expectations. I am now fully confident that if the power should go out during a lengthy engraving, I will not lose the customers product.

This is a very good home backup power source. I have only hooked it up to try it, but it did very well. It was able to run my central heat pump unit, refrigerator, several lights and a 65 inch tv with no problem. The only downside I have seen so far is it loses about 5% of its charge every day, so it has to be plugged in all the time and allowed to charge once a day.

I bought it about a month ago. I received the my station and solar panels together. This is A1.
