FAQ
How does the STREAM system work?
The system prioritizes solar energy. When solar generation falls short of the power demand, the battery automatically steps in to make up the difference. If there’s still a shortfall, the grid supplies the remaining power.When solar output exceeds consumption, the excess energy is first stored in the battery. Any additional surplus can be exported to the grid, depending on your settings and in compliance with local regulations.
What is required to enable energy balancing between multiple STREAM Series units?
All devices must be connected to the same network and added to the same “Space” within the EcoFlow app.
Does the STREAM Series need to be connected to Wi-Fi and the EcoFlow app?
To access the full functionality of the STREAM Series, a connection to Wi-Fi and the EcoFlow app is required. Bluetooth or LAN-only connections will not support features like remote control or historical data tracking.
Is it normal for the product to heat up during use?
Yes, a temperature rise during use is normal and does not affect the product’s lifespan. The unit has passed rigorous testing and includes overheat protection. For best performance, install it out of direct sunlight with at least 3 cm clearance from walls or objects, and away from flammable materials.
Can I install the STREAM Series by myself?
The system can be self-installed and maintained. However, in the UK, local regulations require the EcoFlow STREAM DIY Cable to be wired into the distribution board, which must be done by a certified installer or electrician.
Will the excess power generated by the STREAM system be fed into the grid?
If you disable the feed-in protection switch in the EcoFlow app, the excess solar power will be fed into the grid.
How does the system continue to supply power during a blackout?
For safety and compliance reasons, the STREAM system will automatically detect a grid anomaly and stop feeding current into the grid during a power outage. You can then plug in your appliances directly into the AC outlets to use internal battery or solar power.
Can I receive compensation for excess power fed into the grid by the STREAM system?
Compensation policies may vary by region. You should contact your local grid operator using the contact information provided on your electricity bill to inquire.
Can third-party solar panels be used with the STREAM Series?
As long as the panels meet the input range for the PV port and use the same type of connector, they can be used. Each PV port’s input range is: operating voltage 15-60V, operating current ≤14A.
How many microinverters can the STREAM Series support? Can third-party microinverters be used?
Due to regulatory limits, it is recommended to connect no more than one microinverter.
Each MPPT of the STREAM Ultra/Pro has a maximum power of 500W. Can I connect solar panels with more than 500W to each port?
Yes, as long as the solar panel meets the conditions of operating voltage (15-60V) and operating current (≤14A). This can optimize solar utilization during low sunlight conditions.
If there are multiple devices in the STREAM system, will it prioritize using up one device's power before starting to use another's?
Not necessarily. It might prioritize using one device's power or discharge multiple devices simultaneously. The system employs an intelligent charging and discharging strategy based on the current power levels of the devices, the power consumption of the appliances, the actual connection setup, and your settings in the app. Thus, the discharging performance of specific devices may vary.
What does the AI TOU feature of the STREAM Series refer to?
The AI TOU feature means that the EcoFlow app will use dynamic electricity price data from the local power company to perform smart charge and discharge strategies based on peak and off-peak pricing, maximizing your electricity bill savings. This feature requires a subscription.*An AI TOU strategy will only be generated when the price difference between peak and off-peak is substantial enough because charging and discharging involve losses. If the economic benefits are less than the battery loss, charging and discharging will not take place.
Can I connect the STREAM Series to the output port of a Portable Power Station? Can I connect a Portable Power Station to the STREAM Series' AC outlets to use it as an additional power pack?
No. / No. The Portable Power Station can only be charged by the STREAM Series products, not discharge to them. If you need to expand capacity or power, you can increase the number of STREAM Series products in the STREAM system (up to 6 devices per system).

the support for the shipping was very communicative and fast response. so the first impression is positive. about the product itself, the moment you understand how everything is connected to each other the onboarding linking proccess is very simple a few clicks. be aware that if you change the gird-tide output from 800W to 2300W in some countries as Builgium you need to register this with your regional electricity manager. the app is responsive and it would be great if they can provide more statistics in the future and also add option for if you have an old solar panel installation and now you want to use the stream with the smart meter. all the power from the old solar panels the system will see as if there are no equepments or devices turned on. So be aware of this but the charging and the injection to the gird does take this in concederation so it is not a big problem but it would be grate if we can add two smartmeters to use one for the old installation and one for the new to sub the total from each other. other than that my usage is almost Zero now becuse i have them just for a few weeks .
STREAM Ultra is a great 2kWh storage add on to any balcony solar system. Recommended.
No viene con el smart meter de ecoflow aunque aparece una foto
Ce micro-onduleur powerstream de chez ecoflow est un petit bijou , une pépite !!! ????
Aspect ?
Qualité du matériel ?
Fonctionnalitées?
Le fet de pouvoir brancher n'importe quels panneaux solaires dessus en fait un gros ++++?
L'application avec indications de la production en temps réel des panneaux solaires que j'ai contr?lée au compteur linky est encore un gros ++++?
Du coup j'ai fais comme beaucoup d'autres j'en ai commandé un deuxième ??
Je recommande as tous ceux qui veulent ce lancer dans le solaire pour faire baisser voire annuler la consommation d'électricité les yeux fermés ????
Merci a vous ecoflow pour ce petit bijou !!!! ????????????
Super Content de mon achat
Déjà utilisateur de plusieurs produits EcoFlow, j’ai ajouté l’Ultra X à mon installation solaire. Je cherchais une batterie bidirectionnelle pour stocker le surplus de mon installateur solaire sur le toit avec des micro onduleurs, et celle-ci fait parfaitement le job.
il y a juste une prise à brancher, pas de c?blage complexe et pas besoin de modifier l' installation existante.
Le design est très joli elle passe très bien en intérieur, mais peut aussi être installée dehors gr?ce à son indice IP étanche.
A noter pour suivre et gérer les flux d’énergie, il faut un compteur compatible (Shelly 3EM ou celui d’EcoFlow). J’utilise le Shelly pour l’instant, mais je pense passer à celui d’EcoFlow, qui fonctionne même sans Internet s’il est sur le même réseau que la batterie.
Très satisfait du produit pour le moment
??
Super produit ! Simple à brancher, l’application téléphone est facile d’utilisation et mise à jour régulièrement.
De bonne économie en perspective !
Je recommande sans hésiter !
Merci Ecoflow !
Onduleur qui permet à l’écosystème d’avoir une gestion intelligente de la recharge et décharge de l’énergie provenant du réseau et des panneaux solaire . Matériel de grande qualité et performant
Sí, el Powerstream hace un buen trabajo. ?Todo funciona muy bien!....pero debo se?alar que hay que comprobar previamente la tensión básica de la casa. Aquí en las monta?as tengo un voltaje máximo de más de 250 V al mediodía. Depende de la sociedad Szrom. ?Apago el dispositivo según el aumento de voltaje antes de que lo haga él mismo!
Emballage soigner bien costaud j ai plusieurs ondulateur d autrearque celui bride à 800 w mais bcp de chose compatible et l application est top
J'utilise 2 powerstream avec 4x400w de panneau Trina solar vertex S , je suis très satisfaite, il ne me manque plus que la batterie delta 2 max pour parfaire l ensemble ??
Ohne Probleme durch Fenster und Fenstertüren
Qualit?t super ecoflow halt
Ahora voy a comprar unas más para acumular más energía
Produit correspond à la description, facile à installer
le poids et la qualité de l'appareil lui donne une allure robuste
rien à redire sur la finition, bien pensé malgré de petits bugs au niveau de l'appli, mais qui ne nuisent pas à la production et l'injection de l'électricité.
je recommande ce produit qui me satisfait pleinement pour le moment.
Je songe à en acheter un autre dans quelque temps
Buen producto.
Satisfecho con el sistema ecoflow. Lo que mejoraría es más capacidad de la estación de energía ultra. Por lo demás todo perfecto.
Destacar el servicio de atención al cliente, muy atento.
Die EcoFlow Stream Serie ist für mich interessant, da sie als eine der ganz wenigen ?All in One“ Balkonsolaranlagen den Inselbetrieb unterstützt. Allerdings sind nicht alle Komponenten dafür geeignet.
Die einzelnen Komponenten unterscheiden sich in der Anzahl der Solareing?nge (Ultra 4x, Pro 3, Max 2x) und in der M?glichkeit diese im Inselbetrieb zu nutzen (Ultra, Pro, AC Pro). Keinen Inselbetrieb k?nnen Max und AC, keinen Solareingang haben AC und AC Pro, siehe Bild von der Gegenüberstellung.
Jeder Solareingang hat einen eigenen MPPT (multi point power tracker) mit maximal 500 W Eingangsleistung.
Für den Inselbetrieb gibt es zwei Steckdosen, die zusammen mit maximal 1200 W belastet werden k?nnen. Kaskadiert man zwei Ger?te mit einem Spezialkabel, soll man diese im Inselbetrieb auch mit 2400 W belasten k?nnen.
Alle Komponenten kommen mit einer 1,92 kWh Batterie, die neue Komponente ?Ultra X“ hat die doppelte Batteriekapazit?t und liefert gleich 2400 W bei entsprechend h?herem Gewicht und gr??eren Abmessungen. Ich würde dieser in jedem Fall eine Kombination aus Ultra und AC Pro vorziehen, die lassen sich leichter bewegen und dorthin stellen, wo gerade Strom ben?tigt wird, z.B. als Absicherung für den Kühlschrank oder für die fette Musik mit Lichtshow am Badesee. Allein fürs Elektrogrillen auf dem Balkon mit 2400 W reiner Solarenergie aus dem Inselausgang mag diese Komponente interessant sein.
Im Video ein AC pro im Inselbetrieb mit einer alten 100 W Lampe und einem CD-Spieler.
Die Verarbeitung wirkt sehr wertig und robust, wie man es von EcoFlow gewohnt ist.
Der AC-Stecker mit integrierter Sicherung ist ein echtes Highlight: Er l?sst sich leicht an- und abklemmen und bietet zus?tzlich Sicherheit im Betrieb.
Die zwei integrierten Steckdosen k?nnen nicht nur Strom ausgeben, sondern auch einspeisen – ein echtes Plus in Sachen Flexibilit?t. ?ber beide Steckdosen zusammen k?nnen maximal 2.300?W entnommen werden. Wird nur ein Stream-Akku verwendet, stehen daraus bis zu 1.200?W zur Verfügung; die restliche Leistung wird bei Bedarf aus dem Netz bezogen. Sind jedoch zwei Stream-Akkus miteinander verbunden, kann ein Akku 1.100?W und der andere gleichzeitig 1.200?W liefern – insgesamt also die volle Leistung rein aus den Akkus.
Ist ein Smart Meter angeschlossen wie der von Ecoflow oder Shelly 3em pro kann das system wenn bsp. mehrere Stream akkus im Haus angeschlossen sind , den PV ?berschuss den akkus selbst?ndig zu verteilen.
Im Video ist bsp. eine Split Klima Anlage via Schuko Stecker direkt an der Stream Batterie angeschlossen
Sonne ?? auftanken und gezielt wieder verwenden, so l?uft die Wohnung in den Sonnenmonaten autark.
Facile.. exterieur ou interieur , wifi Bluetooth.. fonctionr seul ou en pilotage application génial et les mise a jour apportent leur lot d améliorations..bref Parfait.. en plus il est beau !!
J'utilise le power stream et les batteries ecoflow pour stocker le surplus d'énergie solaire, que je renvoie la nuit dans mon logement.Deplus J'utilise les batteries nomades dans mon camping car et sur des chantiers. Bon produit.
Top como todos os produtos ECOFLOW.
Sehr zuverl?ssige Firma
