EF ECOFLOW Stream 800W Micro inverter

I ordered this to dip my toe into the world of solar panels, and it's safe to say I'm now hooked. The inverter comes with some mounting bolts for putting it on the wall, and connecting the panels to it is really easy. You can have two different strings of panels at different voltages without issue, which is what I'm doing. That way, if you've got some old panels and want to add new ones later on, you can do so without having to match the panels to the old ones. Output is clipped down to 800W, so you can add more panels if you want to get a higher average output. I'm aiming for 1150W of panels, to get the most out of it. Something to note - the new UK plug in solar legislation says the plug must be a moulded-on OEM one, and the cable supplied has bare conductors for a plug or hard-wired installation. As others have mentioned, the app is good, but the connection is lost when the inverter isn't making power. It can't sip from the grid to maintain the connection when the panels aren't generating power. At the time of review, the inverter is £122, which I found to be excellent value for the quality of the kit. The fact that you can change the connection cable and hook it up to an ECOFLOW battery unit is even better, as it adds to the functionality. Be aware that the cable comes as a separate package. Mine arrived a few hours before the inverter itself, which did worry me.

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.

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.

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.

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.

Well packaged the mains output lead arrived one day and the unit the following , great communication with seller haven’t installed yet quality looks very good indeed well built

This inverter appears very well made. Delivery was very quick and included a 5m cable ready to put a plug on. I purchased in readiness of the rule change 1st September. Before I purchased I spoke with Ecoflow customer services who assured me the inverter is certified and approved for use as soon as the rules changed September 1st. I tried on the 1st to register but the inverter didn't show as approved so I was unable to. I left it a few days and tried again. Same issue. I spoke again with Ecoflow who assured my everything will be OK in a coupple of days. Waiting for the power grid to update the list. A few days later I tried again with the same result. I again spoke with Ecoflow who again told me to wait a couple of days. As of 22nd September there are no ecoflow products showing on the myplugin.solar website where you must register within 28 days of installation. I have returned my inverter, not because it is faulty which it is not, but because of the registration issue. If these do become approved for solar plugin I will most likely buy another. On the whole I am very happy with my power station and get good results from my panels. I sincerely do hope the issue gets remedied soon.

I should have bought this years ago. Very impressed with the product and ease of installation. Took me 15 minutes to install and redirect solar power from battery feed to mains. The app is very useful and lets you know what power you are generating. Customer service was excellent during a delay in them receiving stock. I have 4 120w panels that I used primarily to charge batteries as a back up in case of loss of power. Can quickly change back if needed in a powercut.

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.

Super Gerät funktioniert einwandfrei und war leicht einzurichten

It's a Very Good inverter with a 10 year warranty if you register at the Ecoflow website Easy to install and configure with the app. So far it doesn't heat up as much as the last inverter that I had. I'm happy so far.
