have me start off by saying the EcoFlow Delta Pro 3 is the biggest power station I ’ve review to date . At 115 pounds , it scarcely qualifies as portable . The 4 - kilowatt - hour ( kWh ) capacitance alone is enough to put it comfortably in the category of dwelling house backup , but a bunch of lineament make it pliant enough to go out the planetary house once in a while , too .
EcoFlow Delta Pro 3 specifications
EcoFlow Delta Pro 3 setup
The EcoFlow mobile app is as racy as ever . Once paired up , you could remotely monitor the Delta Pro 3 , even outside your home meshwork . you could remotely turn over it on and off , get datum on usage , set up automations , or really get in the weeds by establishing charge and discharge limit point , scheduling tasks , and bind in voice assistants like Alexa and Google Home . Of course , if you have other EcoFlow machine , you could also manage them here and have them exercise in concert with one another .
The front presentation of the Delta Pro 3 has most of the information you ’ll take , though . It shows how much power is left , both as a matter of fourth dimension base on current utilization and an overall percentage . It also shows wattage in and wattage out so you could keep things more or less balanced . Individual release let you work on certain sets of plugs , depending on what you need .
EcoFlow Delta Pro 3 build quality
The EcoFlow Delta Pro 3 is the first might station that ’s made me go “ wow ” when call for it out of the boxwood . Battery packs do n’t tend to have the most exciting designs , but this one await like a dang Cadillac . Superficial ? Sure , but the Delta Pro 3 is self-aggrandizing enough that you might not be capable to just squirrel it away in a water closet . If you ’re going to have technical school taking up space in the open , it might as well look good . Besides , I need all the help I can get convincing friends that batteries are cool . badly , I ’m dyin ’ out here .
The EcoFlow Delta Pro 3 has a extendible sleeve and rearward steering wheel built - in . They ’re not just nice jot — they are dead necessary to move this thing around . At one point , I somehow observe myself stuff the Delta Pro 3 through a torrential deluge and up three escape of step to our testing field . That was for certain a two - man job , but also conveniently gift me a chance to confirm the Delta Pro 3 ’s IP65 rainproof military rating . The two handles have faux - leather strap Velcroed around them , which I found more a hinderance than anything .
EcoFlow boasts that the interior construction of the Delta Pro 3 takes a page from EVs , with a unibody frame that integrates the electric cell into the structure . This create it ideal for pile multiple chained battery packs on top . It was sure enough able to sustain my weight without any buckling .
The rearward dialog box has an array of inputs uncommitted , including for eV . The nice design hint here is that the hack cover can slide into the body of the electric battery once they ’ve been flipped opened . This way they are n’t fall through in the breeze , or uncollectible , blocking any cables running around back there . Similarly , on the side , near the front , two door opened to reveal additional outputs .
EcoFlow Delta Pro 3 performance
Like most of EcoFlow ’s major power stations , the Delta Pro 3 uses a lithium branding iron phosphate ( LiFEPo4 ) chemistry , which we care to see . Yeah , that likely added a act of weight due to reduced muscularity density liken to nickel note manganese atomic number 27 ( NMC ) batteries , but that also mean increase stability and less unelaborated supply range of mountains . Besides , we ’ve jolly much sacrifice up on portability already .
In our tests , the EcoFlow Delta Pro 3 average out 3.7 kWh of discharge electrical capacity across multiple cycle . That ’s a little shy of the list 4 kWh capacitance . These discrepancies are n’t entirely unheard of , though . enfeeble a barrage fire completely is really bad for its overall lifespan . That tell , I normally chalk up these gaps to the direction system maintaining a buffer . lodge the station from 0 % consumes closer to 5 kWh from the wall , which indicates a average pct is being lose . Charging speeds were about what you ’d expect : three hours to go from zero to 100 % .
The big feature film that sets the Delta Pro 3 up for home championship is 240 - V output signal . While most things in your house operate at 120V , bigger gismo require more juice , which is out of reach of smaller power stations . These 240V appliances can include heat ticker , air conditioning whole , piddle heaters , and other heavy - duty home necessities .
If for whatever reason you see yourself in a blackout and desperately require toast , tea , and a pizza pocketright by , you’ll be proud of to hear that the Delta Pro 3 is able to run a wassailer , kettledrum , and microwave simultaneously without bound off a round . These are high - demand appliances , so I was impressed to see them all scat at once .
There are a lot of fun ways you’re able to scale up your power store with the Delta Pro 3 , and I ’m going to blast through them before you have a chance to debate me on my definition of “ fun ” . One of the ways you may do this is by hooking it up withEcoFlow ’s Smart Panel . It provides uninterrupted power to your house ’s important systems like air conditioner and Deepfreeze when the power storage-battery grid goes out . This apparatus can also quietly salve you a few bucks by excite up the Delta Pro 3 overnight when rate are low , and drop off back into your family when rate are at their high . If 4 kWh just is n’t enough to sate your menage ’s thirstiness for mellifluous , sweet electrons , you’re able to always splurge on two expansion packs that bring the total system of rules capacity to 12 kWh .
I was able-bodied to test out the Delta Pro 3 with EcoFlow ’s portable 400 - W monocrystalline solar panel . It being objectionably hot on the East Coast ( routinely over 90 point Fahrenheit ) meant I could also put the operating temperature limits to the test too . The 400W panels were proportional to the Delta Pro 3 , which is to say , massive . Even during overcast period of time , the panels were create enough power to offset the drain from a full image of charging personal devices . If you ’re go through the trouble of hauling the Delta Pro 3 off - storage-battery grid already , and you forebode stay out there for awhile , a big solar jury is an gentle addition to the frame-up .
EcoFlow makes a big to - do about the Delta Pro 3 ’s uninterruptible index supply feature . This means you may have your wall outlet pass power through the assault and battery right to whatever gadget you need to run , and in under 10 milliseconds of the wall power being cut off , the Delta Pro 3 kick in . I was able to see this in action at law through my desktop estimator , which was able-bodied to keep fly the coop without a reboot when the wall mightiness was cut . There are n’t too many instances where this form of characteristic is exceedingly crucial to me , though . Maybe it would be useful if you were run a server that had to stay up no matter what , or did n’t want any col in security photographic camera transcription .
In the same nervure , EcoFlow brags about the Delta Pro 3 ’s sub-40 - decibel racket level . Again , this is n’t much of a business organisation for me personally , but if your fundament of comparison is a gas generator , and you ’re using the Delta Pro 3 where you ’d care to unbend , this may be a useful addition . Other great power Stations of the Cross I ’ve sample have their fans kick in when I ’m charging them , but it ’s never been so loud as to be disturbing .
Should you buy the EcoFlow Delta Pro 3?
At first , most folks will balk at the EcoFlow Delta Pro 3 ’s $ 3,699 hint retail Mary Leontyne Price . But for those that have shopped around for a whole - dwelling house energy backup and actually have a budget for it , that telephone number is likely to land in an satisfactory image . For example , the 4 - kWh power station fromGoal Zerois going for $ 3,399.Bluetti ’s 5 kWh stationis $ 3,499.Anker has a 3.8 kWh systemfor $ 3,999 . Anyone A-one - serious about domicile energy musical accompaniment is looking at even high damage tags that come along with baron stations in the 10 kWh range of mountains .
You ’re going to be devote a pretty cent for these kinds of system no matter which fashion you cut it . On the top , they ’re rate to last a long time .

EcoFlow aver that can take you over 10 class , depending on how hard you ride this thing .
While the Delta Pro 3 is pitch as portable , it ’s a tough tilt to make . If I was going to set up an R.V. for the whole summer , then sure , I could see myself hoofing the Delta Pro 3 in and out of the proboscis for the head trip to and fro , but not more often than that . Nine times out of 10 , I ’m leave it at house . It ’s just too much machine to convey out nonchalantly for a weekend getaway . There are much more portable option for that .
Provided you ’re square in the market for a permanent or semipermanent power storage solution , it ’s really hard to happen something bad to say about the Delta Pro 3 . At the worst , I ’m pretermit wireless charging that some power Stations of the Cross put on top , but even then , a battery this big is probable to be sitting in the garage or somewhere else where phone charging would n’t be occur much .
The Delta Pro 3 ’s robust connectivity lets you keep tabs on your system whenever you involve to through a squeamish mobile app interface . expandible resolution permit you tie it in as tightly to your home as you could give to . tricky styling salves the painful sensation of bear to lug that much weightiness around . gamey yield ensures you could keep even your biggest electrical demands meet in causa of an outage . alfresco of an emergency , EcoFlow ’s wide product mountain chain used in concert with the Delta Pro 3 can help you save on your electrical bills by charging up when rate are cheap .
