EcoFlow 100W flexible solar panel
And last but not least, the component that gives us the “free” electricity in the first place. EcoFlow sent me four copies of their flexible modules, so let’s unpack it.
To prevent damage during transport despite 258° of flexibility, everything is wrapped thickly in foam and reinforced all around with sturdy cardboard.
Even though it also works, of course, for the classic balcony power plant you would rather go for larger, rigid panels. These here are particularly well suited for use on, for example, a caravan.
For the sake of completeness also here again the specifications, more info on the product page at the manufacturer. By the way, the operation of two modules in series is no problem.
Since the whole thing is to hang provisionally on the only available free outside wall, where also sun comes, I have printed me a few brackets.
Not pretty, but rare. The hooking into a gap at the outer frame of the window works amazingly well, the few storms of the last time here in the north were absolutely no problem.
For the first testing it is enough for now, but “real” solar panels for mounting on the roof are still to come.
By the way, with the flat cable grommets simply coming through the rubber seal of the windows to the inside works wonderfully. I even sprayed some water against the window with the garden hose and everything is still tight.
Summary and interim conclusion
The trappings here are coherent in any case. Everything is very well packaged, many accessories are included or can be purchased separately, and there are appropriate instructions everywhere, for example directly on the cables. However, there are also just as many warnings, so read first and then do it.
I have the complete package now some time in operation and already a large block of notes, more about this in the next parts of this small series. Some of the problems I wanted to mention, I can already discard since promptly fixed. In general I have the feeling that especially the PowerStream is still under active development. A solid basic framework is already in place, but there are still some polishing steps to be taken.
But a few words about the hardware, which should be the primary focus of this first part: 10 years warranty for the inverter is really decent, but the most expensive part of the system, the Delta 2 Max, is “only” given 5 years. By the way, it is not suitable as an uninterruptible power supply (UPS), because the switching time of about 30ms is simply too long. This is also explicitly pointed out in the manual, but the function as an emergency power supply (EPS) in bypass mode is given.
In EcoFlow’s own store, where there are often better prices than in the Geizhals comparison, you really still have to work a bit on the clarity. Various combinations on parts have different savings, so you almost have to create a table on how to buy the whole thing together most cheaply. And the bundle proposed here is also completely bananas, there you would just buy three inverters.
For the moment, it only remains for me to give a preview of the next part: Setup of all devices via the app, first yield results of solar energy and all kinds of comments. I was also able to have a very informative conversation with a developer of EcoFlow, which was allowed to be completely without marketing blah blah. In addition, I would of course like to know from you what else you might like to know or I should try out.
The test sample was provided by EcoFlow without obligation. There was and is no influence on the tests and results. There was also no compensation for expenses and no obligation to publish.
