Just what I needed

I plan to use this to run a few of the most important items in my house during a power outage. Between the solar panels and my Honda eu2200i, I can keep a charge on it even during an extended outage. Since the unit is portable, albeit heavy, I can take it anywhere I need quiet, clean power.

Best deal I've seen yet!

Special thanks to EcoFlow for offering such a great deal on the Delta Pro 3 and 400W portable solar station. I've been wanting to develop battery backup/solar capabilities for a while but haven't been able to afford a complete starter system until this great sale. I plan to purchase an add-on battery in the next few months.

Couldn’t be happier

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.

Excellent source of independence

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.

Only 2600 Watts of Solar Charging?

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.

Works great but could use a light to see buttons

I’m happy that the DELTA Pro 3 works exactly as advertised. The only difficulty I encountered was when using it at night in my camper i had to get a flashlight to see the buttons and the ports. A backlight to the ports and buttons would have made it easier to use.

Extendable Handle failure on two dp3’s

Purchased two dp3’s and two extra batteries. Best working performance on the market. Both were delivered with non-working extendable pull handles. They need a new source. Imagine having the top of the line suite case and you can’t pull it behind you. Or, you can’t store it because it does not retract.
