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 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!

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.

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.
