EcoFlow STREAM Microinverter

Not cheap, but build quality and software are top notch.

Easy to setup, easy to access over the internet. No issues at all for the first week of use.

EcoFlow DELTA 3 Plus

Costco has this at the warehouses for 500 dolla, 550 online

EcoFlow DELTA Pro Ultra X

works but dont believe the hype

so out of the box this unit works. it has several issues all revolving around software. first issue is the TOU and cost savings settings on the unit. if you are using this as a grid assistted system (plugged into an outlet for charging from the grid) it will prioritize that above all else. no matter how you configure the settings it will always pull maximum wattage from the grid to keep the batteries at full capacity. even when you have surplus solar it will limit solar input to prioritze grid charging. second issue is cell balancing. this is what led to the battery warranty issue i had. it will run one battery to 0 while all others will have 70-80 percent left. they have done several updates and it has gotten better but still has as much as 40-50 percent difference between batteries. also the loss is way underlisted. i am seeing as much as 5 kwh per day loss under 15-20 kwh per day draw. standby with no draw is around 2-3kwh per day. batteries are listed at 6100wh but real world i see around 4-5kwh. then once you set the 10-90 chrage discharge limit you have about 3kwh usable battery

EcoFlow STREAM Ultra

Ecoflow Stream Ultra zero feed-in not quite

My setup is: 2x Ecoflow Stream Ultra connected via paralel cable Ecoflow Smart Meter Ecoflow Microinverter 800W connected to first Stream Ultra EU 230V version 2x Trina Solar 450W connected to first Stream Ultra's MPPT 2x Trina Solar 450W connected to Stream microinverter Zero feed-in is enabled in the app Microinverter is connected to AC1 port of first (primary) Stream Ultra that is connected to the grid, on AC2 wifi router, couple of cameras and two lamps are connected (total of aprox. 35W up to 80W when the lamps are ON), nothing is connected to the second Stream Ultra, he is only connected to the first one via Ecoflow paralel cable. The system is basically OK, but I have a couple of issues. The main issue is that zero feed-in is not 100% which can cause my electricity meter to trip and disconnect. 1. Case: The Stream Ultra can throttle down it's mppt's when it reaches it's set battery SOC max limit (either 95% or 100%, I tried changing it couple of times) but it can not throttle down the microinverter that is connected to the first Stream Ultra's AC1 port. At that point, when it reaches, let's say 100% state of charge MPPT'S are turned off, and no solar is comming in, but the microinverter is still producing power and that power is beeing fed to the grid (photo1,2,3). 2. Case: when the microinverter is producing around 100W or less, the system misbehaves and starts showing that Microinverter is producing 170W, then 60W, then 100W and the power value changes every second and it's all over the place and also start's to export power to the grid. Don't have screenshot from the app unfortunately. When real production is above 100-150W or higher, everything is ok. 3. Case: when for instance a 450W heater, that is connected to the house is turned on, and the smart meter senses that 450W is needed and tells the Stream Ultra put out 450W to the house grid that is ok, a 3-4 second delay is visible untill the Stream Ultra starts feeding that to the house, but when that same heater is turnd off and 450W is not needed any more that same delay of 4 or even more seconds happens and the Stream Ultra is still producing 450W power and feeding it to the house and basically feeding it back to the grid. I understand that some small delay is expected, but 4 or more seconds is enough to trip the power meter. Smart Meter and Stream Ultra should be communicating directly with one another, as it shows in the app when you add and pair the devices, but it seems that it isn't the case. My guess is they communicate through the cloud which causes that long delay and high latency. One note, they are all connected to a stable 2.4GHz wifi

EcoFlow STREAM Microinverter

Just works

I've had one plugged in with 8x100W panels attached (I'm in Utah and can run up to 1200W, but only had 8 panels laying around), two in series to each solar input. It's my third microinverter, but their support has been easy to work. The first one was returned because they didn't realize they had a software error that wasn't really impacting the power generation, it just looked like one of the inputs wasn't working. You can see on the app that they've now combined inputs 2&3 because they're really going through a single MPPT. They sent a new one and it lasted about three months and one of the inputs stopped working. They sent me another and it's now been running for a year and is showing it's input 1.17MWh. The panels are just leaning against my house and about 8" off the ground facing south. I haven't changed anything and it just keeps producing. My power bill is always rated as better than other similar energy efficient homes in the area, and I haven't made any energy improvements to the house over the last 20 years.

EcoFlow STREAM Ultra

Ecoflow stream ultra

this was easy to set up and use. I added it to better control my stream micro inverter. It acts as a gateway and has some battery storage. Biggest gripe is small battery storage and no easy way for just a battery addition for net zero output you will need a power meter I am using a shelly 3em pro 120 for this as that was the only one compatible at the time I purchased unit will output up to 800 wats solo or you can pair it with another for full 1200 or with the ecoflow micro inverter. with the unit acting as a gate way you have two options for self consumption one is to set a manual base load number or you can use a smart meter for auto adjusting. it does have the option for ac coupling but my experience that isn't super efficient because it can only couple the excess solar if you are not consuming the full output amount.

EcoFlow STREAM Microinverter

Simple and easy to use

has worked well was simple to set up. I have not had to contact ecoflow for this I saw some people complain about getting charged for power they send back and yes you can if you produce more than you consume and you do not have net metering set up. However that is not a fault of the hardware. the power company also cannot remover your meter if they do they are actually breaking the law (Utah) and if they threaten you with it point out the bill and let them know they are not allowed to do so. also, if you have measured your base load of your house, you can set the output down from max it outputs of 1200 to a lower level. you do this by setting the amp rating of your breaker. settings grid-tied output power limit the dedicated circuit is 1200 but you can go down to as low as 260 watts and can increase it from there in 5 watt increments. so if your base load is between 260 and 1200 you can set it to that level and you will never feed back to the grid. it will also plug into the ecoflow stream ultra. if you do that teh ultra acts as a gateway to manage the inverter

EcoFlow STREAM Microinverter

One unit working fine, 2nd older unit had MPPT Failure. Warranty Repair in progress.

tl;dr: Good way to expand your existing solar array, but if you don't already have solar probably not that good. --- First off, I already have solar on my roof, and a net metering agreement with my power company. In the 10 years since I installed my rooftop solar I've realized my array is too small now that I have an electric car and I've long wanted to expand my array but didn't want to deal with the hassle of putting in another rooftop system in addition to the one that is already up there. I bought my first EcoFlow STREAM shortly after Utah became the first state in the USA to legalize plug-in solar to easily expand my existing solar. Because I have an existing NEM agreement be aware I _do_ get paid/bank credits when I export to the grid. Most people who don't have solar already and don't have a smart meter will _not_ get paid for power exported. Also YOU NEED A SMART METER or else you will actually be BILLED for exported power. Getting a smart meter can be tricky if you don't already have one. Anyway when the STREAM arrived it worked fine, except for it being limited to a 360w output limit. After watching a review on the YouTube channel "There's a trick for that" I understand now why you really need a dedicated circuit to take full advantage of this unit. YOU REALLY NEED A DEDICATED CIRCUIT if you are going to run this at full power or else you can start a fire. I now have the unit on a dedicated circuit, and it outputs 1,200W when paired with three 450W panels in good sun. My dedicated circuit is actually a 50 amp NEMA 14-50 outlet I already had in my garage. It is just a unused plug I had installed to charge a 2nd EV if I ever bought one. Since it is not being used, I got a splitter on it (since a 14-50 has two 120v legs.) and plug the STREAM into that. In fact it has worked so well (and the 50 amp plug and wiring is massive overkill for the 1,200w load) that I bought a second STREAM unit this fall, and now output a total of 2,400w into the house and grid using both legs of the unused 14-50 outlet. (I got three used solar panels bought off FB marketplace to put on the new unit.) After 1 year of use, one of the MPPT inputs on my original unit failed. Ecoflow quickly got in touch with me after I filled out the warranty form on their site, and got me a return label the next day. I sent the defective unit back on their dime, and am currently awaiting a replacement unit (or for my unit to be repaired). So far the experience has been good, but they have only had my unit returned to them for 1 day so we'll see how quick the replacement gets back to me. The software could be better. For example there is no way to export your data in .csv or any other format. You can't get it out so you are stuck with the EcoFlow app to see how much you are saving/generating etc. Besides the lack of export, the app overall is OK I guess. I wish it integrated the two STREAM units better, but you aren't supposed to have 2 units at one home like I do so they didn't really design the app for that purpose. You can choose one or the other and get the information from one at a time. No way to see how both are doing at the same time. Bottom line: If I was a normie, who didn't already have solar, and didn't already have a net metering agreement with my power company, and didn't already have spare solar panels laying around, I don't know how good this product would be honestly. The point of it is to offset your home's "Baseload" power. You buy this product knowing (again, if you don't already have a solar metering agreement or smart meter) that you will not be reimbursed for any power that you send to the grid. All this does is eat away at the power your home uses all the time. In my case I have figured out my home pulls about 400-500w of power all the time from computers, routers, cable modem, clocks etc... The vampire draw of my house so to speak. So in theory all I would need is a single 450w panel to knock that down to almost nothing and it would only do so during the day obviously. Financially this is terrible. It would take decades to pay itself off. Even at expensive power rates you are going to at best save yourself 50¢ a day, AT BEST. Really more like 10¢ a day. This unit costs almost $400 shipped. You do the math. (and this is before adding in that you need to buy one or more solar panels also) Again, since I DO have net metering, with these two STREAM units I've essentially added 2,400W to my small 3.14kW existing rooftop array. (I am allowed to expand up to 10kW total before I would have to re-apply with the power company for a new Net Metering Agreement.) They don't want you to use this product if you already have solar though. So if you already have some spare solar panels, cabling, have a smart meter, have a dedicated power circuit (important), and want a dead simple way to expand your existing solar capabilities by up to 1,200W, this is for you. Otherwise, probably I would pass.

EcoFlow DELTA Pro 3

DP3 Reliability Problems

Purchased an Ecoflow Delta Pro 3 on 10/4/2025 and plugged into a solar panel setup for HV and LV panels. I have one extended battery as well. Unit has been kept indoors in a temperature controlled office. In March 2026, a temp sensor went bad on the unit which made it think it was too cold to charge. EcoFlow tried to skirt around it with software updates, but eventually decided to replace the unit. Warranty process took a long time, but I did receive a unit that functioned. In October 2026, the unit decided to stop charging from solar. Both HV and LV panels turned off at the same time. EcoFlow responded quickly and identified that there was a problem with the unit. I asked for further details on what specifically failed and was told, "this appears to be a device-related issue. The unit is not detecting or accepting solar input through the affected port, even though your solar panels are functioning properly when connected to the other input." I was quoted a 5 to 7 day turn around time before shipping my unit - "After the warehouse confirms receipt, please allow 5–7 business days" EcoFlow took delivery of my unit on October 21, 2026. I sent them multiple emails asking for an update during this process and did not receive any update until I called them on 11/3/2026. I was connected to their call center who said they would escalate the case. I heard back on 11/4/2026 that, "Upon checking on our end, we regret to inform you that the EcoFlow DELTA Pro 3 is currently out of stock. Unfortunately, we do not have a confirmed restock date at this time." You can purchase a new Delta Pro 3 on EcoFlow's website right now. This really irked me and I have asked EcoFlow for a full refund. I will update this ticket with the current status. Recommend you all steer clear of the Delta Pro 3. If anyone has tips on getting a refund from EcoFlow, would appreciate your help as I'm asking them to refund me the entire order including the extra battery.

EcoFlow Lithium 12V 100Ah Deep Cycle LiFePO4 Battery

2 in series

I bought rwo of these to wire in series for extra capacity for my Pecron E1000lfp. I hook it to the xt60 solar / dc input. It runs at 525w charging the Pecron at 20A. I just ran a capacity test with them wired to an Excelltec xp1100. I ran a 275w load for about 7.5 hrs. Going from 27v to 25.2v. I counted 1.8 kwh through a meter. The inverter is 85% efficient so I estimated total yield of 2.2 kwh.

EcoFlow DELTA mini

Ready to go - out of the box!

No thinking needed. Turn main power on then activate 120 sockets with a button and do almost anything. Portable power, on the go. It has been wonderful for my navigation tablet and phone. I've hooked up a single solar panel with the provided cable, just works. Very happy with the purchase.

EcoFlow DELTA Max (2000)

Flawless at what it does.

I own two of the Ecoflow Delta Max units and each one has two expansion batteries. I originally bought these for potential grid-down scenarios back in the "summer of love".... (2020). All pieces are updated to the latest firmware, and I put a discharge/recharge cycle on them at least once a year. I recently took my refrigerators off-grid and using one power station setup is working well, being charged by 800W of solar on my semi-flat roof. I can charge via grid if I ever run out of sunlight, but not much chance of that in the Arizona desert.

EcoFlow STREAM Microinverter(US)

easy to install

easy to install have had no issues with the system I bought it with 4 panels. I would source my panels separately as i think you can get better panels cheaper from other sources. No problems with the hardware that i got though.

EcoFlow STREAM Microinverter

Works as designed, but not ready for Utah’s grid, and support fell short

I had high hopes for the EcoFlow STREAM Microinverter. Utah recently passed a law allowing small plug-in solar devices without an interconnection agreement, and EcoFlow markets this as plug and play: no installation, start saving. In practice, it wasn’t that simple. The meter problem. My home has an older meter that can’t distinguish power flowing in from power flowing out. Any time the system sent excess power to the grid, the meter counted it as electricity I used, so I was billed for energy I actually produced. I didn’t discover this until months later, when I ran my own analysis of my usage. Rocky Mountain Power. When I contacted Rocky Mountain Power, they told me the device isn’t on their approved equipment list, that they don’t allow these devices on their grid, and that they would remove my meter if I kept using it. This is despite the state law saying no interconnection agreement is required. My state representatives, who helped pass the bill, told me there was nothing they could do. EcoFlow’s support. The marketing promises no installation needed, with no mention of meter compatibility or utility pushback. By the time I understood the problem, I was well outside the return window. Separately, one of the units simply stopped working after a few months. It took weeks of back-and-forth proving it was dead before EcoFlow shipped a replacement, which is still in the box. My review on their site. I submitted a version of this review on EcoFlow’s website in August 2025. More than a year later, it has never been published. That sums up my experience: the marketing is everywhere, but when problems came up, EcoFlow didn’t stand behind the product or support me as a customer. The product itself. To be fair, the hardware works when it works. I liked being able to cap output to avoid sending power back to the grid. But without live monitoring of household usage in the app, setting that cap correctly would have meant building my own monitoring setup. I’m glad I tested it on a temporary ground mount before committing to a dedicated circuit and roof mounting. Even so, it was money wasted, and now both units sit unused. Bottom line: This kind of low-barrier solar is exactly what the industry needs. But until utilities, regulators, and manufacturers are on the same page, it’s plug and play only in theory. If you’re a Rocky Mountain Power customer, call them and confirm your meter type before buying. If they won’t support it, you’re better off with a properly installed grid-tied system from an installer who will handle the utility for you. - The wording of my review was reviewed by AI. I have reviewed the output and it properly summarized my terrible experience. - The Charged Reviews website wouldn't let me select the store I purchased this from, so I selected Amazon. The original purchase store was directly from EcoFlow's main website.

EcoFlow DELTA 2

Excellent, easy to use purchase in 2023.

My wife uses a CPAP machine. When the power goes out (we live in FL). that's a problem. So, doing research, most people were saying get a Jackery 500 or something that size and turn off all the stuff that you would normally run on her ResMed. That seemed like malarkey to me, so I looked for something a little bigger. Hence, the Ecoflow Delta 2 and 2 190w solar panels. Since the initial charge via the wall outlet, I have NEVER powered it from the wall again. With the MPPT built-in, it was a good fit. But shortly thereafter, I thought it stupid to just let is sit there, waiting. I began putting it to work. It runs the washing machine, the slow cooker, an induction burner, charges all of the EGO batteries, even the outdoor Christmas lights for a month each year. I added the external Ecoflow battery before I discovered Will Prowse. So, I have it and use it but wouldn't recommend it. I've also added 4 100ah lifepo4 batteries to help out as needed when we lose the sun for too long. I have a relative that purchased a gas generator about the same time; he hasn't even opened the box yet. The price I originally paid is superfluous as they are much cheaper now and you can get larger units for the same money. But I have zero regrets.

EcoFlow DELTA Pro 3

Expensive but it delivers

I've had 1 of these at my property for about 18 months and it works great. No complaints. It's my only source of electricity and has a 240 plug for a well pump. I use the 30 amp plug with a step up converter because you can't send power the 240 and 120 at the same time. It's small on it's own but I've partnered it up with an ecoworthy power mega 314 (w/ wattlink adapter cable), 900w of panels and It's fantastic. I don't know about the software because I don't use it.

EcoFlow 110W Portable Solar Panel

Generates more than rated!

Love this website Will! I’ve owned a few various portable solar panels made by other manufacturers which never reached their claimed output. Well, I’m very impressed with these Ecoflow 110 watt portable solar panels. These easily reach the rated 110 watts and at times a little over. The construction is excellent and the case it all folds into is well made with a high quality zipper that is sure to last. Yes, these were more expensive than other manufacturers, but worth it. It’s always better to pay a bit more for the good stuff than to feel ripped off by the poor performers. Pluses: Meets and beats rated output. Very well constructed of high quality materials. Cons: My set is a few years old so there’s no stand legs at the rear of the panels. Ecoflow’s design was to use the case to hold these up which is not stable. I need to use whatever such as the car, a bench, whatever to aim these at the sun. I do have a friend with a newer set that now comes with folding leg stands. Summary: I’ll never go with cheap panels again. A few bucks more and worth it!

EcoFlow DELTA 2

My first unit - very satisfactory

I got a Delta 2 in 2024. I used it to get partly through the Palisades fire shutdown. It lasted about 1-1/2 days of the 3-day shutdown. Didn’t have enough solar panels or time to fully recharge. In general, everything about the Delta 2 performed as expected, just needed to set up solar panels better. I am very happy with the unit, build quality, app, everything. EcoFlow is more expensive than other brands, but it just works - EcoFlow is often compared to Apple in that regard. I’m often suspicious of five star reviews, but the Delta 2 is solid.
