Solar Powered Fan with Thermostat and Battery, Exhaust Fan 150mm with 12W Bifacial Solar Panel, Outdoor Ventilation Fan for Greenhouse, Chicken coop, Shed, Garage

Just built my shed...man cave! Was just going to fit a normal static vent,but came across this item instead! Unlike most solar vents this one has a battery back up.runs on solar energy during the day also while recharging the battery.then when sun goes down the battery kicks in running the vent almost constantly.it was easy to install, looks good and works better than I was expecting! Glad I bought and would recommend!

Used to add ventilation in a chicken coop, really easy to fit and set up. Quite powerful at full power and has been working consistently for over 6 months now and not had any issues with it.

Works well just a little bit noisy, battery seems to work for about 8 hours on eco

I'm a bit disappointed with this product. The fan doesn't work at all on cloudy days. While the power storage setup is somewhat impressive, the fan itself isn't very powerful. The battery life claims that it will function even during overcast weather, but that's not true either I would have returned it but for the fact that I had to cut a hole in the glazing of me greenhouse to fit it thumbs down 👎🏽

Great product for my bar needed a fan

im not tech or diy logical at all, was trying to improve issue of 2nd hand smoke coming across garden/into home. Costly way to attempt to avoid neighbour issues. AI chat bots kept referring to changing air movement and I was desperate - i think its a lot of money to throw at a problem. I did eventually manage to rig it up (someone with basic knowledge of tools would have found it simple). The control panel is really not great, hence prompted me to come on & write this, as ive just re-watched the video. Have to really hard press on occassion but other times barely touch, its tricky cos just hard plastic. Just fumbled through programming On temp but have given up for now to complete by setting Off temp. I guess it's quite noisy, but as neighbour is also sitting outside watching videos im trying to not worry about. id rather be able to sit and be in fresh air and hear birds/general outdoor noise. I cant say how much it works as ive been a bit hit & miss with set up, but it certainly is in action -so no issues with solar and battery. today im particularly aware of how noisy the fan is being but you dont seem to be able to adjust speed even though the description says 3 speeds

I haven't managed to get the battery to discharge yet. It's fairly quiet, but does a decent job.

Airflow is extremely weak. I don’t know what I was expecting but it is nowhere near enough to provide much ventilation for an 8 metres cubed (small box) room. It periodically turns on and off for no reason.

La notice n'est pas en français

At first it went well, you do need to place the panel in direct sunlight otherwise the batterij won’t charge and the fan wil not work for long after 2 months the fan has stopt working

Ergänzung: In der Beschreibung steht, dass der Lüfter neu gestartet werden muss, wenn der Akku leer gewesen ist. Ich habe den Lüfter mehrere Monate duchlaufen lassen mit angeschlossenem Akkupack. Obwohl wegen des Winterwetters der Akku sich über Nacht vollständig geleert hat, läuft der Lüfter wieder an, sobald genügend Sonnenlicht auf das Panel trifft. Mit dem Akkupack läuft der Lüfter auch gleichmässiger. Das dürfte die Lebensdauer des Lüfters verlängern. Darum jetzt auf 5 Sterne gewechselt. Ich belüfte einen 5 x 3 Meter Holzschuppen mit diesem 1 Lüfter. Ich habe kein Schwitzwasser an der Decke oder an den Wänden. Er scheint für diese Zwecke auszureichen. Der Lüfter soll meinen Schuppen mit Frischluft versorgen, um Schimmel und Feuchtigkeit vorzubeugen. Dabei habe ich das gleiche Problem wie andere. Sobald der Akku leer ist, schaltet sich die Anlage ab und muss manuell neu gestartet werden. Den Akku kann man aber problemlos weg lassen. Die Stecker sind entsprechend ausgelegt. So läuft er zwar nur tagsüber, aber das reicht. In dem 30 Kubikmeter Raum ist die Luft merklich besser, obwohl der Lüfter für kleinere Räume ausgelegt ist. Der Solarkollektor wirkt stabil und hat einen Rahmen mit Halterung. Ich habe den Halter auf eine Steinplatte geschraubt und den Kollektor einfach aufs Dach gestellt. Zu den Bildern: Bei der Bewölkung pustet der Lüfter immer noch gut. Auch bei schlechterem Regenwetter hat er noch einen brauchbaren Luftdurchsatz. Schade, dass man den Lüfter nicht ohne Akku bekommt oder nach dem Entleeren die Anlage selbsttätig wieder anläuft.

Fungerar bra för att få lite rörelse på luften i uthuset.

Usato in stanzino garage , due e funziona ancora bene
