- How does the EcoFlow PowerStream manage a load greater than 800W? What happens in the app and how quickly does it respond and update?
NOTE: The 800W capacity of the PowerStream depends on your location. Some locations are limited to 600W. At this time, it's unclear if the PowerStream complies with regulations in the UK. Always check this for yourself and use at your own risk.

thank you for the review ! i wish i bought a EcoFlow instead of a Anker Powerhouse 757. . . so many options with ecoflow
I wonder when they will become available in the UK again?
The 800 watt is the margin a cable should safely be able to deal with coming from a different direction then a fused connection from the grid. The 800 watt is like and extra 3 amp being pushed into the cable without a fuse.
It is only safe when the cables are up to good standards.
Quick question .Do the smartplugs work with you are not connected to the internet? The questions being, are these devices connected locally or do they need Ecoflow servers to work? Zendure's smartplugs don't work when their servers are offline...
Another question :-) Do you know if the Powerstream has 2 independent MPPTs or are the inputs internally wired in Parallel or Series? Thanks for the great videos!
I’m really interested in the Power Stream and enjoyed your videos. How’s the system going? Have you been able to work out your savings? Would you recommend and if so what size battery do you think is optimal for the 800w panels?
Thanks for the videos 👍🏻
Good question on the savings. It’s hard for me to say as I tweak my setup all the time so don’t have everything connected all the time. Currently I’m up to £70 but we’re into October and days are short here in the UK. I might put out another video on making the most out of the PowerStream. 👍🏻
Hi !
This is very interesting!
Could you please share your thoughts on this system, are you still using it?
Hi, i got 3 200w with 25.2 voc and 11.74 isc. Can I make these 3 in parallel and plug to powerstream?
Interesting ! So the app actually shows you at any time how much is being used from the grid ? 1st video where I see that. So here for example your house was using 0 from the grid until you started the kettle ?
It doesn't show you everything used from the grid. Only the amount used from the grid needed to satisfy the demand of the smart plugs if it exceeds the 800W that the PowerStream can supply. If you had a heater plugged in elsewhere that wasn't using a smart plug, that would not show on here.
Oh ok great info thank you for getting back to me so quickly @@tdcattech
I wonder if one could use this so, that the Delta would be just a buffer. A sepate Solar system could be: 1-2 kW panels > off-grid inverter > 48 V Rack 5 kW (1 or 2) battery topping up Delta 24/7. PowerStream would be connected Delta and mains. This system could bring to house max. solar capacity of 800 W x 24 h = 19,2 kWh. Maybe you could even add additional 1-2 solar panels to PowerStream on top of that. Excess solar could be used to charge PHEV or even BEV from the off-grid system
I am wondering if the App show the same when the smartplug and powerstream are on different phases ;-)
Further to reply to @kaxalo, can you advise how a Powerstream (without extra panels) would operate in my situation, namely existing solar panels (3.5kWp) on the original FIT tariff (no metering), a solar IBoost diverter that cuts in to heat water when there is is a 400w+ surplus of PV generation, and grid power bought on Economy 7. I would like the Powerstream to behave like a full battery installation, namely that it would charge either when pv generation exceeded normal use plus iBoost use, and/or during Economy 7 period - and that, once full, it would discharge back into the house system when there would otherwise be on-peak grid purchase. Thanks
You’re right, that App is bloody sexy!! 💪🏻👍🏻
what do you think using the power stream with 800w panels without the battery and with or without 4-5 smart plugs? is it worth it?
Same question too
Hello, I have two Solar panels (Pmax 400W, Voltage at Pmax 30.35V, Current at Pmax: 13.19A) and a DeltaMax Pro Ecoflow.
I just bought an Ecoflow Powerstream to directly connect the two panels
My panels are on a rooftop, about 25m away from where I will position the Powerstream (and the DeltaMax). So I need 2 pairs of solar cables with MC4 connector.
For solar cables, given the length but also that there will be only one solar panel per cable, should I take 4mm2 or 6mm2?
Ecoflow sells a cable of 3m in 4mm2 but it seems to me that if long length, you have to take bigger cable ...
A big thank you in advance and congratulations for your work and your videos.
Didier
4mm2 will handle that kind of current without a problem but I would go with 6mm2 to absolutely minimise the voltage drop.
Thank you for the video. My system is an Ecoflow Pro and a Pro extra battery currently without solar, the maximum I can output to the house is 625 watts, for all the powerstream said 800 watts on the box. Have you tried only using the battery with no solar?
Yes, this is normal. The max power direct from battery is c.600W. The 800W is using battery and solar or just solar.
@@tdcattech Interesting, so at night or times when there is no, or very little sunlight, you are down to a maximum of 600 watts. I wonder if there is a way to spoof the solar input with an additional DC input ?
can i connect it to a 12v100ah to this device?
Where have you got the 800w Firmware for the PowerStream? I am living in Europe and would also like to upgrade? Can you link to the Firmware, or explain, how you managed that? Thanks
That's how it was sold. Some regions are limited to 600W and others 800W.
Can 2 Power Streams be setup in one apartment while being controled by one phone or do u need to diff mobile apps to manage two installed PowerStreams ?
Even in the countries where using them grid tie is legal (like Germany) you can't put multiple units on one grid connection or mix them with any other grid feedin devices.
HI. It's probably stupid but I'm asking you. In your opinion, is it possible to connect the two DC inputs of the powerstream to two batteries (e.g. 24V and 100Ah LiFePo4) or will everything burn? Thanks so much for your videos
Do you mean as a pseudo-solar input. I see no reason why that wouldn't work. The controllers wouldn't know the difference. Please someone correct me if I'm wrong. So you could charge these off-peak and then use them to power everything during peak hours.
@@tdcattech hi. I have 6 kWp of solar panels and my goal should be to charge the external BIG battery during the day and use it to charge the Delta2 during the night. So, I’m asking if is it possible to Connect the external battery by the 2 mppt power stream input. Thank you for your response
@@Enrico80 This works for the D2 at least (but only about 100W in is possible on the D2 car input mode and you lose a load in voltage conversions etc, as well as wearing two batteries not one). You can also make the input look like solar if you are smart and get 48v (just remember 48v is enough to kill you). However given the inefficiencies you'd be far better just buying a proper wired in battery system from Solax, or Growatt or whoever.
Still not sure if its best for me. I do 24/7 crypto mining sometomes about 570 watts, Can you set a base load of 570w.
How does it calculate that "Power grid" amount? Is the grid somehow connected through ecoflow, or it is just an estimate of 800w minus actual power requested by smart plugs?
The PowerStream has no 'knowledge' whatsoever of what is being demanded from the grid. It purely knows what it is providing or what it is unable to provide. So if an item on a smart plug demands 1200W, the PowerStream will bump up to its maximum of 800W and the app will then show 400W as coming from the grid (1200-800). If you plug something else in without a smart plug, this is not known to the EcoFlow in any way and the app numbers won't change.
@@tdcattech If you don’t measure the total current entering to the house from the grid (with some meter at the main electric cabinet), How can you guarantee that the system will not inject into the grid? I guess the only option is defining the baseline as “0W” and this way the invert will only feed according to the total consumption measured by the smart plugs. But you are losing the opportunity to cover other small consumption devices along the house not connected to the smart plugs.
@@franciscojaviermorentin9507 Exactly! Here is my take on this App Magic: The Inverter can't know if it is back-feeding power to the grid (to determine the latter, one needs to measure the main incoming fuse, which equipment can determine the current flow direction).
There is a trivial reason for the app to ask for "Other AC loads," i.e., everything below is deemed to be fed to "know" house appliances, a.k.a. "other loads."
These loads can, in fact, be known loads, i.e., the user-estimated base load power consumption and/or unknown appliances within the house. However, power feed to the grid can also be part of the "load" if the "Other AC loads (setting in App)" are set to a higher value than the actual power consumption within the house. I assume, however, that the app will never show any current flow to the grid.
Can you use it without solar panels? just with the battery? Let´s say charge the battery at night with cheaper electricity and feed it into the system during the day to use less expensive electricity
Yes. If the solar is disconnected, it will just take all the power from the battery. Remember that you have a ‘round trip’ loss with this though so your electricity will have to be much cheaper at night to justify this approach.
I have the night saver, which means at night the price is less than half what is during the say @@tdcattech
Saw your video about the round trip. It could be interesting for days when there is much sun to charge the battery at night with the cheap rate to usi it during the day @@tdcattech
I understood what was going on.... Until you mentioned a base load???
What is that?
How much your home uses without any specific appliance being on. It’s the sum of all your 24/7 devices like an internet router, cameras etc. This might be really low for a non-tech household (maybe under 50W) but might be 100-200W if you have quite a few wireless speakers, WiFi extenders, CCTV etc.
Gets bit more complicated, I wanted to use a cheaper 24v 100AH standatd LifePo4 battery , not sure if that will work. Still trying to get Export tariff from Octopus but 99 percent of time NICEIE inspectors are used. Not sure if they will allow. I will show them G98 certificates instead see if Factory Electrician test certificates are enough to keep tjem happy.
I suggest one plugs devices that are over 800 watt simply into the back of the Delta...
If you don’t want any grid use, absolutely.
@@tdcattech You can still use the AC-in of the Delta to keep it at the backup % as set in energymanagement.
This is odd - when your kettle requests 1kw, why does it take from the grid, instead of simply taking more power from the battery?
The inverter can only backfeed 800W maximum into the mains circuit.
Thanks!@@tdcattech
@@tdcattech Is there no way to change the setup so anything more than 800w gets pulled from the Delta? It feels wasteful since the Delta can theoretically provide more power. Or can one perhaps add another PowerStream into the mix?
@@projectphoenix9805 The problem is not the Delta; the issue is the "Unfused" additional current - 3A (or power - 800 W, if you will) being potentially fed into your cables. Boosting the delta output power (and hence providing means to exceed the 800 watts output limit in the inverter) could cause a fire due to overload on the cables (the fuse will not trip since the total current is not passing the fuse). I assume this is why Gremans are keen on the 600 Watts limit (safer than 800 watts).
i just found out about this product. it doesn't appear to be available in the United States though. bummer.
3.5 months and starts tripping the fuse box knocking the power out red light and dead. 10 Yr warranty?! 10 months would have been nice. Don't bother
The ecoflow 800w microinverter is grid tied , so it switches off if there is a poweroutage, how can it be illegal in UK? Freedom of speech, organic small farming,breathing fresh air was also illegal?
The UK rules require that it is wired in on its own spur and probably with a lockable isolation switch for safety. There are *lots* of equivalent cheaper grid tie inverters you can buy off the shelf for this, but you need an electrician to do the install and paperwork. Octopus will even now give you feed in tariffs from non MCS installs providing you've done the rest of the paperwork.
It's considered an electrical safety issue and actually we are no different to places like Denmark on this. Only some bits of Europe allow plug in grid tie.
