ECOFLOW Stream 800W Micro inverter, Smart Solar Inverter WiFi for Balcony Solar System, IP67 Waterproof, App Control, MPPT

I gave 3 stars earlier, but raised it to 5, the cable was included in the price, but they had run out of stock due to a hgh demand. it arrived a week later. The EcoFlow stream is very sturdy and high quality. Very easy to install and It worked straight away. Although you need to bind it to the battery system if you have one. There is a learning curve to using the app, however Google AI was useful at taking me through it. Using my home smart meter and the app, it was evvident that the system is very quick to react. Very impressed.

Great product. Missing Cables! Overall, it’s a great product. Now reduces my electricity bill by a small amount every day. However, it didn’t initially come with the solar cables that should have been included. I had to threaten with Trading Standards to get what I had already paid for. What was once an amazing company is going downhill fast in terms of customer service

Feels very solid and seems to work as intended. The app makes setting up and monitoring the device easy and the WiFi is very good, able to pick up the main house WiFi despite being out on the garage! I have it booked up to a couple of 450w solar panels and it is performing well. Don't forget to get the mating mains cable as the connector provided is pretty unique. The App confirms the input from each panel so it has true mppt for both inputs.

Only had this 5 days but want to say a few things to add some clarity for those thinking about buying it. This arrived very promptly in only a few days. The cable arrived first on its own via the postie. The unit arrived a couple of days later also via postie. The Mains cable comes with a connector one end to connect via a screw-together connection to the main unit . The other end is bare with the Live, neutral and earth wires in standard UK colours and labelled with printed stickers. The only connections on the micro inverter are the above mentioned for its mains connector and 2 sets of MC4 sockets to connect to solar panels. There is no direct and simple way to connect this to a delta type power station for saving any excess automatically. (we have one and a cable to connect with but it is impossible to do it that way with this version of the microinverter) To connect to your solar panels, you need them to have MC4 connections from them. They will need leads long enough to go from their location, to the place you affix the microinverter. The cable from the microinverter is not massively long. I think about 10ft and 1cm thick An external weather protected socket is the easiest access place for it but we arent electricians and thats all up to the buyer to arrange. It can handle upto 800watts of input current which is 400 for each pair of MC4s. The panels must give at least 20volts to be seen. The pairs feed into the 2 MPPT controllers which then turn the solar feed into something the unit can convert to AC for the grid. We have tried this with our camping panels (2 rated 24 volts,one is 200w and the other 180w and one rated 20 which is about 120w) It works and the MPPT controllers are efficient, you can see how they perform within the app. The app can be downloaded to your phone. We already had the app for our batteries so just searched for the microinverter which it found instantly. It upgraded its firmware first thing. You need to click on it ,it wont just do it So, it can feed the power into the house electrical circuit. You can see what is coming in on the app. It shows import and house usage, of that which it imports. It does not play with our ecoflow delta batteries as it has no manner of connection to them. Performance. Over the 5 days we have imported 5.85 KWH Of that imported wattage, 111 watts was lost to the grid, the rest was used by us. You cant tell from the microinverter what is lost to the grid, but we have a seperate smart meter monitor installed and can see through that. The camping panels have been plugged in from about 11am till 5pm as thats when we have no shade where we can put them and I moved them about to catch the sun every hour while we are experimenting with things still. It hasnt rained. Its been cloudy 2 days, sunny 3. Conclusion Works well Wont comply with stand alone delta 2 or better due to no connection capability. Hence the new battery inverter combination machines. Its affordable if you dont have the reddies for the all in one things. I think Ecoflow 'could' make their own smart socket plugs and have them cooperate with the app to allow plugging in of a battery for charging on auto whenever the wattage exceeds the houses current use and that would make the whole thing far more budget friendly.

An excellent piece of equipment, well made and delivered quicker than I thought. It came in two separate boxes, which seemed strange. The inverter in one, and the mains connection cable in another. It did not come with any cables to connect solar panels, contrary to what some YouTube videos imply. So I purchased them separately. The app is nice but only works when solar is supplying it with power, as it drops network connection. Still very pleased with it though.

I've had solar panels for years but have been off grid using batteries but this bit of kit is absolutely amazing, it cuts out so much hassle and pumps everything into my house so most of my items run off it for free, I expect it to pay for it self very quickly at this rate, I can't recommend this enough

Works pretty well. The app is a bit quirky but pretty intuitive overall. The inverter is solid and has a bit of weight to it. I would've given more stars but I didn't receive the mentioned MC4 connection cables.

The design looks sleek and contemporary. And it works straight out of the box. The App that goes with it works really well and I will miss that as I've returned the unit due to overheating and it throttling back to 50% for several hours whilst it cools to a reasonable temperature. I can understand overheating in the tropics, but in an outbuilding in the UK at 20c you'd think it would work okay with a decent air gap around it. I've seen folk on the web rig up fans to cool them and thought 'yeah right', but actually they were simply overcoming this very issue. Since replaced it with a spare Growatt string inverter I had which has worked flawlessly in the same conditions. But then that has a much bigger heat sink which I think is the issue here. To keep the cost down I think they have compromised too far on the passive cooling aspect. Do I think its a good micro inverter and the answer is yes caveated with if you cool it or you are happy to loose generation on hotter than 20c days.

Simple d'installation et très efficace. De plus l'application est très bien faite. Je recommande.

He comprado este Microinversor de EcoFlow y tras probarlo durante un tiempo me ha gustado su funcionamiento. Se trata de un Microinversor de 800 w de potencia, con un sistema muy fácil, ya que solo hay que conectarle dos paneles solares y con el enchufe que incluye lo conectas a cualquier enchufe de tu casa, empezando a inyectar la electricidad que produce. Es así de fácil, ya que el Microinversor incluye tanto el cable depara conectarlo como los cables para conectar los paneles, por lo que no tendrás que comprar nada más que los paneles, aunque también lo venden con ellos incluidas. En mi caso puse dos paneles de 505 w, ya que por la ubicación que tengo no dará el 100% de su potencia, siendo compatible con la mayoría de los paneles del mercado, que usen tomas MC4, que son las habituales. Respecto a la producción después de casi dos meses de uso ha sido formidable, el pico de uso ha llegado a los 790 W, variando según transcurre el día o si hay más nubes o menos. El Microinversor genera energía aunque no reciba el sol directo, son con la luz del día, eso si, bastante menos que cuando recibe el sol en la totalidad del panel, y necesita estar conectado a la luz, por lo que no lo podrás utilizar si hay un apagón, para eso necesitarías baterías, que yo no he instalado. Incluyen una aplicación gratuita de EcoFlow con la que conectaras mediate wifi el Microinversor a tu teléfono donde verás en tiempo real la producción que estás generando, con gráficos diarios, semanales, mensuales y anuales, muy fácil de utilizar y de entender, donde almacena todos los datos. En mi caso después de estos casi dos meses, ha tenida una producción de 133 KW/H en el mes de Agosto, que está genial, con días en el mes de Julio de 5,4 KW/H, por lo que estoy muy contento. Principalmente monte este sistema para amortizar un poco el consumo de la depuradora de la piscina que tengo y ha sido todo un acierto, ya que más de la mitad del consumo de está ahora me sale gratis, además de contribuir con el medio ambiente al ser energías que no contaminan, a mi me ha gustado, además de un servicio técnico que contesta bastante rápido ante cualquier consulta que les hagas, que para mi es bastante importante…..

Eccezionale, recensisco dopo 6 mesi, nel quale non ho avuto nessun problema, ne di funzionamento ne con la ricezione del segnale wifi lontano circa 8 metri. Installazione semplicissima, accessori compresi per ogni esigenza. Applicazione fantastica, controlla in tempo reale la produzione dei pannelli individualmente. Preso durante un piccolo abbassamento di prezzo e mai pentito dell'acquisto. Ci tenevo a dire che è sempre stato all'aperto sotto le intemperie invernali.

Ich bin mit dem Ecoflow Wechselricher sehr zufrieden. Er ließ sich einfach montieren. ALLE erforderlichen Kabel waren in bester Qualität mitgeliefert worden. Das einrichten über App. Ist kein Problem und der Inverter funktioniert einwandfrei.

Dopo un mese di utilizzo posso condividere la mia esperienza con questo microinverter, che ha superato le aspettative. Avevo due pannelli da 330W inutilizzati da anni in cantina e non avrei mai pensato di poterli recuperare così facilmente. Scoprire la possibilità di usarli con un sistema plug & play è stata una sorpresa, soprattutto considerando il prezzo di poco superiore a 100€. Il prodotto arriva con tutti gli accessori necessari (cavi MC4 e cavo Schuko), l’installazione è semplice e la configurazione tramite app è stata immediata. Una volta fissati i pannelli, la produzione è partita subito. Nonostante il periodo invernal, il peggiore per il fotovoltaico, sto registrando una media di circa 1,12 kWh al giorno, per un totale di oltre 30 kWh prodotti in un mese. Per due pannelli dimenticati in cantina è un risultato eccellente. Sono molto contento e in conclusione posso dire che installazione è stata rapida, app molto intuitiva e la produzione immediata. Un acquisto che consiglio a chiunque voglia recuperare vecchi pannelli o iniziare con il fotovoltaico in modo semplice ed economico.
