ECOFLOW DELTA Pro Portable Home Battery, Expandable Portable Power Station, 3.6kWh-25kWh, Huge 3600W AC Output, Solar Generator For Home Backup, Travel, Outdoor Camping

Fantastic piece of gear. Very very pleased with the Delta Pro. Being used in our van conversion with solar and a DC to DC. The app is so simple to use. Very impressed. Insane power of this has us running everything for days at a time. This includes a 1700W Air fryer, the EcoFlow Wave 2, loads of lights, 4k TV, Google TV, Google home mini. Awesome product.

Although very heavy I'm using it to power tools in my workshop. Works great very happy. I'm using a 400w solar panel. Could do with more in future but still charges in an reasonable time.

Good quality item, works very well expensive initially but seeing the benefit over last few months. Also went away for a couple of months and left it running certain things all good on return and good saving on electric bill

Love the way this product works and i was a happy ecoflow customer until the socket where you plug in your solar cable dropped back inside the unit. Initial contact was good, collection of the unit was prompt but since then it has been a shocking experience given the cost of the item. The repair should have been a simple one, but after 3 weeks of asking how they were getting on i was then told my batteries were faulty and i needed another unit. I was surprised as the unit had not shown any battery issues prior to the socket going faulty. However, i accepted there offer of a good quality refurbished unit. What was delivered was a million miles from the pristine unit i had sent in for repair. This unit had a cracked case, rust inside the USB ports and significant signs of wear and tear, so i could not accept it. Following apologies for that, they arranged collection but the Fedex guy could not take the item as he was expecting a label which was not supplied to me by Ecoflow, so i have contacted them again and they have just gone quiet on me. So now I am having to escalate with Amazon and potential legal claims if that does not work to get another generator or my money back. These generators have become very popular and are being sold on the high street at places like Argos! I am so disappointed and can only hope i get a resolution. If i do i will update the review, but right now I can only give 1 star due to having spent over £3000 and nothing to show for it!5/9/24 update. Eventually Ecoflow did send me a brand new unit, but it took a lot of persistence on my part to get the correct resolution. I can only say that since then the unit has performed fine. I still have some concerns on whether these units will last long enough to repay my investment, but time will tell. I will say again that when operational these units are fabulous in my opinion, the app provides great flexibility in configuring the device. Lets hope the company can maintain a level of service that matches the investment.

Simple to charge, easy plug in for inverter output.

One Year update May 2023:Dropping 1 star off (was even thinking taking 2 off) - poor fan management as it is incredibly noisy you'd need a separate room with closed door for it.Delta Pro is still probably the best performance overall system currently (May 2023) due to its large capacity, big-ish solar input (1600w), very powerful AC output (3600w sustained) and well built solid system. It has been working daily and consistently (mostly) for past year for me. Powering office and even kitchen appliances (kettle, air frier, microwave etc.) without a sweat. Support team was great but after my repeated suggestion for fan management improvement they seemed stopping responding to me which leading me to point out the most / worst part of the Delta Pro - that jet engine noise! You probably won't find any review pointing this out (I did mention in my initial feedback when got it).I am running our fridge/freezer (being the most energy hog in our house, approximately 3.5kwh/day) and with initial startup (drawing 1600w for less than 1 sec) the fan would be on full blast, despite next 10mins drawing less than 150w. With an ambient room temp of around 19'c and machine temp around 20'c - I do not see why the fan needed to be one full blast for all the remaining 10mins (also, as when in AC charging 200w the fan would not turn on at all whole night, despite passing thru providing that initial load). This is one of the examples of fan management can be massively improved but EcoFlow team unfortunately dismiss all my numerous suggestion they should look into this. This is sadly my rant for otherwise a brilliant system. There are YT videos people swap out smaller EcoFlow units with much quieter fans!In contrast, I have now purchased Anker's 767 to supplement my Delta Pro which almost felt like a lifesaver as it operating silently only when at full sustainable output fan with becomes audible (still quieter than Delta Pro). Had Delta Pro have such quiet fan, I would have bought one more unit with supporting batteries to run the whole house.Initial review from May 2022:After considerable research and trawling user feedbacks on the internet regarding to Battery Systems, we have decided with EcoFlow's Delta Pro and bought it to power our office with two 32' 4K monitors with 16' MacBook Pro M1 Pro. And wow we were blown away by every aspect of this product, it has to be the best battery system on the market currently. This review is for the quick initial 3-day since received it, will revert back with any further updates later on. Also shout out to their Customer Service whom had been great too, prompt to respond on any questions/doubt I had.Quick summary: if you are looking for a long battery life (extended charge/discharge full cycle, Delta Pro support 3600 cycles still holds 80%+ capacity), high quality product with huge output capabilities for either portable or home off-grid use, Delta Pro is probably the best you can get. It can be charged via multiple input sources, and most useful with the inbuilt 1600w MPPT that any solar panel can charge it as easy as plug and play; another amazing capability is that it can be charged via electric vehicle charging point! We plan to get a second unit and possible 2 more battery packs to off-grid (at least summer time) powering our whole house/office. Unlike Tesla Wall, we can move these batteries anywhere we like with us and can always add required battery capacity (each unit being 3600w). The unit is heavy (as needed for the power capacity and better materials), delivery was super fast, next day for me (apparently the warehouse is near) and come well wrapped in a pallet as the unit weights 100pounds (49kg).Detail breakdown:First of all, Delta Pro's build quality is amazing, really well build and felt very sturdy and well constructed. Although outside shell is plastic, I have seen video that they are made with honeycomb structure for added strength and being a 3600w battery, I also feel a bit more safe handle it. Unit come with few cable accessories and the EV charging adapter. Edit: correction - not EV charging adapter but was the Smart Generator Adapter. will have to separately purchase the ev charging adapter unfortunately.Secondly, Delta Pro has huge capabilities and in emergency case can even power the small/medium ish house (but we have not tested this) with boost output of over 3600w sustained. It was a breeze for us to test everything we intended it to last 3days but not tumble drier as we dont have one. everything else in our office/house was handled with ease. It takes less than 2hours to completely fully charge up the unit via wall-socket with the standard power plug provided.Thirdly, there are various of ways can charge up Delta Pro: solar panel, wall output, generators, ev charging points, ecoflow's delta pro battery packs etc. We mostly using solar and connecting via standard MC4 connectors it was a simple plug and play as you can see from the screen prints that with our 320w solar panels, in cloudy vs full sunlight conditions both cases we can power our office whilst still charging Delta Pro!Regarding the product's ecosystem, there are additional battery packs can support 2 more with each Delta Pro bringing total battery capacity to over just 10kw (3.6k x 3) with simply plug and play; and can potentially have two Delta Pro in parallel to support up-to 7200w power for almost all domestic (even medium workshop) power needs. They have a smart house panel in the works apparently will make them Tesla Wall equal (but these have wheels can move with us on demand) - although I can't wait further would go with a transfer switch to the consumer box route.Finally, I found the EcoFlow app works well with the unit, can control all aspects of the operation and also have access to full info of the power usage/charging status etc etc.Moving on to any other considerations, if anything I would say EcoFlow can improve on the fan noise, when it is charging/discharging more than 100ws, the fan kicks in to keep the unit cool but it is quite loud (for almost silent M1 Mac users). All in all, we are really impressed with EcoFlow and Delta Pro, will try to set it up for our off-grid living!

If weather permits excellent storage battery

A great unit does everything I could possibly want it to do, good build quality clear display Echoflow UK provide a good prompt service delivered on a small pallet because of the weight, it may shock you how heavy it is but it is a beautiful design and I couldn't be happier with it
